Solar will remain strong in 2017 With the industry expected install more solar in 2016 (10 GW) than in any previous year, and with a clear path to 2022 under our feet—thanks to an extended ITC—it’s a great time to be in solar.

I say this with confidence, despite concern that renewable energy development won’t prosper—and may even come to a halt—under the new presidency. For every commentary igniting panic over possible solar and wind policy repeals, I’ve read another instilling faith in the strength of both markets and their bipartisan support.

Having heard out both opinions, I tend to side with the latter. True, the new administration could slash renewable energy tax credits, revoke programs and ignore recommendations, guidance and goals of the previous office. This would certainly hurt the pace of renewable development but definitely not destroy it. Perhaps eight years ago the absence of a federal focus on renewables could have devastated solar energy growth. But if it happened today, the market will survive—we’re so established that we could take the hit.

While we still have educating to do, solar is no longer such a blue versus red issue. I remember former SEIA President Rhone Resch touting, “We’re not an issue, we’re an industry.”

Based on the number of representatives from both parties I see supporting renewables, this idea is catching on. Studies, such as those from the Pew Research Center, confirm that most Republicans and Democrats favor expanding renewables.

Renewable development does help combat climate change, but politicians and citizens alike are also seeing it create energy

independence, dependable jobs and additional electricity for our increasing population.

Yet, we can’t be blind to industry challenges.

Cheap PPAs in the utility market are making it more difficult to be profitable. Investorowned utilities in California are set with enough renewables to fulfill RPS obligations through the next few years. It’s clear the industry needs to find ways to reignite procurement.

Offsite commercial solar—community solar, virtual NEM and offsite wholesale projects—is expected to grow fourfold over 2015, according to GTM Research, but onsite commercial development is still challenging. Solar may be booming, but it’s getting more difficult and expensive to find residential solar leads. This issue’s special business section provides insight into ways to overcome these challenges.

Barry Cinnamon of Cinnamon Solar gave the industry a “pep talk” in a recent blog. To keep the momentum around solar going, Cinnamon said we need to do “more of what our industry has been doing for the past two decades. We need to continue to reduce costs, we need to create more domestic jobs, and we need to do a much better job educating the ‘red’ states and new policymakers about the benefits of solar.”

If you watched Michelle Obama’s December television interview with Oprah Winfrey, you may have caught her overarching theme of “hope.”

She stressed the importance of thinking positively and supporting the new administration, saying, “What else do you have if you don’t have hope?...

The words that we say moving forward—all of us—it matters, which is one of the reasons Barack and I are so supportive of this transition, because no matter how we felt going into it, it is important for the health of this nation that we support the commander-in-chief…So we are going to be there for the next president and do whatever we have to do to make sure that he is successful, because if he succeeds we all succeed.”

I think that if we, as an industry, do our best to follow her lead, solar will succeed too. SPW

A solar installation in downtown Anchorage was commissioned on winter solstice, one of the darkest weeks of the year.

The installation, designed by Arctic Solar Ventures, will supply 15% of the 20,000 square-foot commercial office space’s annual energy usage, significantly reducing its overall annual energy costs. Alaska receives roughly the same amount of annual solar energy potential as Germany, which has more than six times the amount of installed solar than the United States.

New solar financing council Washington, D.C. The Solar Energy Industries Association (SEIA) and the Solar Energy Finance Association (SEFA) are joining forces and forming a new entity under SEIA to support wide-scale, lowcost solar deployment through better access to investment capital. Under SEIA, the two entities will better serve their membership and act as a single voice and organizing force for current and potential solar developers, investors and lenders.

Arizona ends net metering Arizona Arizona utility regulators voted to end its net metering late last December, drastically reducing export rates. Though current solar customers will be grandfathered at current rates for 20 years from interconnection, new customers will only be granted 10 years. Critics fear the move will end mainstream solar in what has been one of the largest residential solar states.

The San Antonio solar market is on fire.

About 207 MW were installed statewide in 2015, according to Environment Texas.

Solar advocates credit a successful incentive program, which has fed consumer interest despite the state not having a net-metering law. The market ranked sixth nationally for metropolitan growth in 2015 and seventh for the spread of solar, setting the pace for the Lone Star State.

ranberry bogs and solar installations at first seem like a weird combination. Why crowd usable farmland with solar?

One bog in Carver, Massachusetts, proved the relationship could work. A 1.1-MW ground-mount sits atop the plants because shade actually creates an ideal growing environment for the cranberries underneath. The land now has a dual purpose—growing fruit at a more productive rate while also generating solar power.

Although this solarized cranberry bog is not the flooded-type that Ocean Spray commercials have familiarized, owner Mike Paduch does use the land to grow healthy plants that are later transplanted to other bogs for harvest. So while there isn’t a sea of floating red berries underneath the solar array, there are living, growing plants that need careful attention.

Cranberries grow on vines low to the ground and can survive only under specific conditions. They thrive in wetlands layered with peat soil, sand, clay and gravel during an April to November growing season. Air pockets inside the berries allow them to float, which is why most bogs are flooded to more easily separate the berries from the vines during harvest. These unique growing conditions, and the fact that the bog in Carver was already planted with live vines, made the installation of a solar array slightly tricky.

“One of our main concerns was the timing of the install,” said Dan Girard, director of EPC and global business development at S&C Electric Company, which was the EPC on the project. “It was explained to us by the owner of the site that in spring, plants are more flexible, as compared to summer or fall when the plant becomes more brittle and more substantial damage could occur.” Pile driving had to be done earlier in the year so as not to damage or break the cranberry vines on the functioning bog.

Local contractor Synergy Solar assisted with the installation. President Noah Jones said the project was challenging because of the logistics— machines had to be carefully moved around the living plants.

The largest challenge on this project was the tight, confined space. We had to protect the live plants.

“The largest challenge on this project was the tight, confined space,” Jones said. “We had to protect the live plants. We had to use a matting for the machinery. Any time we moved a machine, we had to make sure we had matting under it so it didn’t rip up or damage the plants. We had to have a decent force of manpower just to move the matting.”

However, the layered ground conditions provided a silver lining for positioning piles.

“In New England, we typically run into a lot of refusals when we run the piles,” Jones said. “Cranberry bogs are mostly sand. This was pretty easy to do.”

Although a smooth installation, the piles did have to go a bit deeper than normal for a secure foundation. Jones said RBI Solar’s ground-mount system used on the project was easily adaptable to depth differences.

“The advantage to RBI is their ability to change their post lengths to get different embedment depths. That was useful,” he said. “The ability to change as

S&C’s Girard said the arrays were designed to be higher than standard rack level for future harvest and flooding considerations.

The project, which was completed in 2016, is owned by Connecticutbased Lodestar Energy, a long-time S&C partner. Astronergy 310-W modules and Yaskawa - Solectria Solar string inverters were also used.

Although initially assumed to be an impossible installation combination, cranberry bogs and solar prove to be a good working pair. Installing solar on usable farmland doesn’t necessarily mean giving up growing.

What solar contractors NEED TO KNOW about NEC 2017 The 2017 triennial update of the National Electrical Code (NEC) is complete and has been released for adoption. Though AHJs may take months or years to adopt the latest edition (California won’t adopt the 2017 NEC until 2020), it’s important for solar contractors to know what’s coming.

Here’s an overview of the changes that will have the most impact on solar installation.

Rapid shutdown expands Probably the most argued change to

the 2017 NEC is in article 690.12, Rapid Shutdown System (RSS). Compared with the 2014 RSS, the 2017 edition is much more proscriptive and, more importantly, will usually require module-level isolation for compliance.

What’s changed: All PV system conductors are now controlled conductors. The limitation placed on a conductor depends on its location in relation to the PV array boundary or point of entry into a building. The PV array boundary is

NEC Adoption by State

located 1 ft from the PV array measured in any direction. Conductors inside this area, or less than 3 ft from point of entry into a building, must be reduced to 80 V or less within 30 seconds of RSS initiation. Conductors outside this area, or more than 3 ft from the point of entry into a building, must be reduced to 30 V or less within 30 seconds of RSS initiation.

Impact on installation: There are three options for complying with RSS inside the PV array boundary:

1.

The PV array can be listed or fieldlabeled as a RSS PV array.

2. Conductors will be limited to 80 V within 30 seconds of initiation of RSS. 3. If the PV array has no exposed wiring, no exposed conductive parts, is not closer than 8 ft to any other exposed grounded conductive parts and at least 8 ft from the ground, then compliance with RSS is not required.

Residential Installations

Projects Other_1-17_Vs3.indd 16

Option 1 is not yet available because the standard has not been developed.

Option 3 would require raceway for all wiring in the PV array up to the PV module junction box, which few PV modules currently support. But the other requirements could be met with existing equipment. This leaves option 2 as the one most likely to be used to comply. The requirement is two part, first the 80 V limit and second is the 30-second timeout. The 80 V limit will require breaking up higher voltage strings into segments that are 80 V or less. Because almost all modules have a temperature-corrected Voc of more than 40 V, each module must be isolated. This can be accomplished by many means including microinverters, DC-DC converters or simple remote controlled contactors.

The compounding factor is the 30-second timeout. If the array is disconnected from an inverter, the voltage on the conductor can take several minutes to decay below 80 V on its own due to the DC input capacitors in the inverter. Active discharge of the voltage, or a contactor internal to the inverter, is usually required to meet the 30-second requirement, which means that putting a disconnect on the module alone is usually not enough to provide a compliant system. The RSS system must also address the inverter discharge.

While in the 2014 NEC there was no prescriptive requirement for initiation, the requirements for RSS initiation are called out in detail in the 2017 NEC. Basically, there will be three ways to initiate RSS as outlined in 690.11(C): 1.

Service disconnect, in which removing utility power to the main service panel would initiate RSS.

16

2. PV system disconnect, disconnecting the PV system would initiate RSS. 3. A stand-alone RSS initiation switch.

It’s anticipated that simply removing utility power will initiate RSS in most PV systems without any backup power functionality. This is the simplest method to achieve compliance. With the growing use of energy storage or direct PV system backup power without storage, allowing the PV system to provide backup power RSS initiation will require the use of option 3 with a shutdown initiation switch.

System grounding redefined Significant changes have been made to the wording concerning system grounding, but this will actually have little impact on how systems are installed.

What’s changed: With the advent of non-isolated inverter designs that do not allow for DC system grounding, a new term “functional grounded” has been introduced. This is defined in the NEC as, “A PV system that has an electrical reference to ground that is not solidly grounded.” The term “electrical reference to ground” is not defined but is basically a system designed to detect when there is a failure in the insulation of any ungrounded conductor, raise an alert and shut down the PV system. This is a sea change in system grounding design because much of what was previously defined as solidly grounded in the DC circuits is now functional grounded and is installed in much the same way as an ungrounded system.

In the process, 690.5, describing GFDI, has been moved to 690.41(B), and GFDI will now be another form of functional

grounding. Section 690.41(A) lists the acceptable forms of PV array system grounding with 690.41(A)(6) being a catchall to allow for new equipment. Equipment grounding is not affected by any of these changes. The only solidly grounded PV systems will be small systems allowed by the 690.41(B) exception.

Impact on installation: For most PV arrays, functional grounding will be provided by the inverter. DC circuits will be installed as functional grounded circuits with no conductor marked as a grounded conductor, similar to ungrounded systems. Disconnects will open both current carrying conductors, and section 690.9(C) will require an overcurrent protection device (OCPD) only on one polarity of the circuit—the positive or negative—as long as all OCPDs are in the same polarity of the circuit.

Section 690.47 covering the grounding electrode system has been significantly simplified from prior NEC cycles to take advantage of the new functional grounded type of system grounding.

Other NEC changes worth noting Section 690.7(A)(3) was added to allow a PV system 100 kW or larger to have the maximum PV array voltage calculated under the supervision of an electrical engineer using methods other than the lowest expected ambient temperature.

Section 690.31(C) will now allow the use of USE-2 as well as PV wire as single conductor in PV arrays with any type of system grounding.

Section 690.47(D) requiring an additional auxiliary grounding electrode has moved to 690.47(B) and has been made optional.

Section 705.12(B)(2)(3)(d) provided a method for interconnecting to centerfed panelboards using the 120% busbar rating allowance instead of requiring engineering review. This change will also be made to the 2014 NEC. Section 705.12(B)(6), the requirement for AFCI protection of microinverter AC circuits, has been deleted. This change

will also be made to the 2014 NEC. Section 310.15(B)(3)(c) requiring temperature correction for conductors in raceway exposed to sunlight has been significantly simplified. It now only applies if the raceway is mounted closer to the roof than 7/8 in. and the correction is 33°C. Because most standoffs are going to be higher than this, temperature correction will rarely be a factor.

Section 312.8(B) was added to provide requirements for the addition of power monitoring equipment such as CTs to switch or OCPD enclosures. Because PV monitoring system CTs are often added to the PV AC fused disconnect, this section will need to be understood to size the enclosure appropriately.

A brand-new

year for the solar roof fter a somewhat tumultuous year for roof-integrated solar, we’re heading into 2017 with unprecedented attention and momentum.

The past 12 months of lows and highs have left roof-integrated solar shingle and tile manufacturers in a better position than ever, but not without some serious whiplash.

Until 2016, there was little general interest or awareness in roof-integrated solar. Most people in the solar industry considered building-integrated photovoltaics (BIPV) a niche market appealing to those willing to pay the markup for a more expensive and often less efficient residential solar system.

Homeowners had shown interest in roofintegrated solar, but general awareness of roof-integrated options was low.

With Dow Chemical’s discontinuation of its Powerhouse Solar Shingle product line in July 20

2016, what many considered to be an already dubious market took a real delegitimizing blow. Dow joined an ever-growing list of roof-integrated solar manufacturers that could not find a path to commercial success, and the solar roof was faced with misconceived questions about its market feasibility.

Dow’s failure was seen by some as a reflection of the solar shingle market as a whole, while in reality, it was due to Dow’s faulty technology strategy.

Dow’s shingles used thin-film technology, which is less efficient and much more difficult to manufacture at a small scale than standard crystalline technology. Mono/polycrystalline solar shingle products currently on the market are not bound by the same price and scale restrictions. Dow’s exit certainly presents questions for the viability of thin-film as a technology strategy for emerging solar markets, but it is not indicative of slowing market demand for roof-integrated solar.

And yet, to the casual observer, roof-integrated solar might have seemed fraught with industry doubt.

So when Elon Musk announced in August that Tesla was developing its own solar roof product, the solar industry was forced to consider whether roofintegrated solar will be the future of residential solar, and the general public’s awareness increased exponentially.

Cue the whiplash mentioned earlier.

With Musk’s announcement and subsequent unveil in October, roofintegrated solar received a major boost in market acceptance and awareness, sending customer demand skyrocketing through the end of 2016. At SunTegra alone, we saw about 300% revenue growth in Q4 over Q3, plus a huge uptick in inquiries about solar roofs submitted through our website.

customer demand. And with this momentum still behind it, the solar roof market is coming out roaring in 2017 and shows no signs of slowing down.

Take RnR Market Research’s 2015 BIPV study as an indication of expectations for the solar roof market.

The study predicted the BIPV market would grow from $3 billion in 2015 to more than $9 billion in 2019, reaching $26 billion by 2022. According to the study, roof-integrated solar is expected to remain the largest segment of this market throughout the forecast period.

Despite skeptics, the research clearly predicted a burgeoning market space for roof-integrated solar. The challenge we faced until now was consumer awareness.

Looking at where we are at the beginning of 2017, having a major cleantech player like Tesla and a celebrity CEO like Musk advocating

roof-integrated solar will certainly only continue to attract the attention of the mass media and consumers. If Musk’s previous pursuits are any indication, the “Musk Effect” has a potent and tangible ability to help emerging markets explode.

Electric vehicles, home battery storage— these only became modern symbols of luxury and amenity once Musk injected them with his hype and eye for design.

This “Musk Effect” has already dramatically changed public perception of the once-overlooked roof-integrated solar system. With Tesla expected to launch its solar roofs at the end of summer 2017, the escalating media buzz will create more opportunity for current products on the market, including shingle and/or tile products from companies such as CertainTeed, LUMA Resources and our own SunTegra. Every Musk announcement and update will catalyze

demand and foster exponential growth in this market for many years to come.

As market awareness builds through 2017, the key will be to educate consumers on the economic offerings of roof-integrated solar. Musk’s unveil might have left observers starry-eyed for 2017, but it has been noted he avoided a discussion of his product’s functionality, cost or any other financial metrics. With only an unclear implication from Musk that Tesla’s roof will cost less than a regular roof and will “by the way” produce energy savings, the fresh buzz around roof-integrated solar is ripe for education. That will be a job for solar shingle manufacturers with products currently on the market.

No doubt, the selling points are there. With the price of producing crystalline technology continuing downward and efficiency on its way

up, mono/polycrystalline solar roof systems are seeing an increasingly level playing field with roof-mounted solar systems.

Perhaps the most compelling argument for roof-integrated solar is the savings to consumers when installed as a new roof. For a homeowner already paying for materials, labor and transportation, the difference in cost between a new roof plus solar versus solar shingles becomes negligible. A roof-integrated system saves on the racking and footings needed for conventional solar modules, as well as the cost of traditional roofing materials. For the 5 million new residential rooftops installed in the United States every year, roof-integrated solar is a no-brainer.

With an aesthetically superior residential solar system on the market that makes economic sense to potential customers, the solar roof will see greater customer demand than ever before. To paraphrase Musk, who wouldn’t want a roof that looks great, saves you money and generates electricity?

It’s a brand-new year for the solar roof. SPW

Inverters are LEADING THE WAY to meeting new rapid shutdown requirements The NFPA has published the 2017 edition of the National Electrical Code, and technically, as of Jan. 1, any state could adopt the code’s new rules.

However, as with any code cycle, there will be a lag in adoption. California is just beginning to enforce NEC 2014 this year.

Still, any solar contractor installing on “the rooftop of an occupied building” needs to be aware of the new code changes.

One of the most controversial additions to the 2017 code mandates conductors within 1 ft of the PV array boundary or point of entry into a building, or within 3 ft of an entry into a building, must be reduced to 80 V or less within 30 seconds of rapid shutdown initiation. Of the three options the 2017 code allows for compliance with rapid shutdown, the use of module level isolation is the most 24

readily available using current equipment.

Module-level isolation has been hotly debated in the industry since it was proposed during the 2017 NEC revision cycle. First responders see limiting the voltage anywhere within the array to 80 V or less as a step toward increased safety, and MLPE providers are obviously on board since their devices would be required. Other parties like SEIA, SunPower and SolarCity opposed the addition, concerned it would hamper the industry in terms of cost and reliability and not entirely convinced it makes arrays safer.

Meeting NEC 2017 rapid shutdown today While NEC 2014 rapid shutdown requirements only limited voltage for the wiring outside of a certain perimeter

around the array, NEC 2017 added detail by limiting the voltage at the module level. While there are various ways to achieve this, only one is possible with the technology and standards commercially available today—isolating or separating modules in a string through modulelevel electronics. Inverter manufacturers have taken the lead on providing solutions to meet the code.

Using power optimizers or microinverters alone, or as integrated smart or AC modules, will inherently meet the code requirements. A string inverter will have to be paired with some type of module-level technology. String inverter manufacturers are taking different approaches, offering DC optimizers for every module or partnering with MLPE or panel manufacturers with integrated

technology that already meets the code— optimizers, microinverters and even chips.

For example, SMA America has partnered with Tigo Energy to offer a range of MLPE options, from those that simply shutdown the module to those that offer additional benefits such as monitoring and shade mitigation. The company’s director of marketing Brad Dore said the right choice for contractors depends on their business model.

“What’s the most cost effective way to meet the code, and what does your design dictate you need?” he asked.

“With many incumbent microinverter and optimizer companies, you’re putting one of these MLPEs on each module no matter what. With SMA’s, if an integrator just wants shutdown capability, they can utilize a particular MLPE that’s just for that purpose. It doesn’t provide monitoring, shade mitigation or other benefits of an actual optimizer, but it’s less expensive. Likewise, there are module companies that have MLPEs embedded into the module that can provide similar benefits. It’s really up to the integrator to determine what’s best for his or her business model.”

The future of rapid shutdown It’s important to be aware of the options available today to meet the code, just in case you’re lucky to have an inspector keen on immediately enforcing NEC 2017 (Massachusetts may be one of these early adopters).

But Mike Mahon, technical training specialist at SMA America, noted the code actually

out in the 2011 cycle requiring arcfault circuit interrupter functionality.

That code was written, and 2011 came without any commercially available way to meet the code requirements.”

But implementation was delayed and solutions came to market.

Dore said another interesting aspect is how the code requirement impacts the cost of the system. “It’s in the best interest of the industry’s growth to provide additional safety but in a responsible way so the cost is minimal,” he said. “The residential market, so far, has been a little better able to absorb the additional cost of using MLPEs. Some of these ‘to be developed’ solutions may find applications in the commercial market, which has a little less price elasticity. The same code applies to the commercial market, even though that market is more sensitive to pricing. When you think about the construction and design of a rooftop, it’s something that will need to be taken into account. The solutions are still to come.” SPW

“While it was decided this addition should be in print before the next code cycle, there was an understanding that there’s a lack of maturity in the solutions available for compliance,” he said.

Mahon explained that one compliance method describes a ULlisted rapid shutdown system (RSS) PV array, which is a UL standard that doesn’t currently exist. “It would require a standard testing procedure to be developed to achieve that listing,” he said. “Then an array or install could be in compliance.”

The SunSpec Alliance is also working

There is a lot of work to be done before the full suite of solutions is available. That’s not terribly unusual. delays enforcing rapid-shutdown requirements in 690.12(B)(2) until January 1, 2019. This is to allow time for the industry to develop a product safety standard for rapid-shutdown PV arrays, so that arrays may be listed and labeled as rapid-shutdown installations. The NFPA recognizes that some options don’t exist yet.

on communication protocol that allows module manufacturers to produce a basic remote control switch for shutdown. “As time goes on, we’ll have more and more options for getting there,” Mahon said.

“There is a lot of work to be done before the full suite of solutions is available,” Dore agreed. “That’s not terribly unusual. We saw a similar play

New mounting system provides QUICK WAY to install bifacial panels on residential roofs Bifacial solar panels are picking up steam, especially in groundmount conditions or on flat, white roofs where sunlight can easily reflect onto a panel’s backside. Even in not-so-ideal conditions, bifacial modules are standout products not requiring grounding (since they’re dual-glass and frameless) with a higher lifetime power yield. And when companies like Trina Solar provide an industry-high, 30-year power warranty, why not bring these panels to residential rooftops?

The issue has been in how to successfully (and effortlessly) mount these frameless panels to sloped planes.

One company has spent the last four years and $1.5 million in DOE funding to find a solution. California’s SMASHsolar set a goal to eliminate complexities

We use a bolted connection with a toggle on the backside of the decking and a stainless-steel hex bolt on the top. We call it the ‘secured decking attachment.’”

Using this lax installation technique, the assembly feet are attached to the modules on the ground, and the full system is lifted onto the roof and bolted to the decking—an easy snapin assembly on the ground, and then a direct attachment to the roof.

In demanding vehicular applications, battery degradation can start to cause problems because the battery can’t always perform to meet the instantaneous and long-term demands of the vehicle’s operating system.

However, the battery is able to be reused in other applications like EV charging stations.

Giving electric vehicle batteries a SECOND LIFE in solar projects UL and the University of California San Diego are working to bring repurposed EV batteries into the solar market faster.

Electric vehicles and solar are often categorized under the umbrella of green technology, but what exactly is their relationship? Should the solar industry pay attention to what’s happening with EVs? Panelists in an educational session at Solar Power International 2016 thought so.

“It’s important to look at all potential technologies together because they’re complementary. There’s a lot of synergies between them,” said Angela Strickland, director of product development for the Southern Company Energy Innovation Center, during the “How are trends in electric vehicles impacting solar and storage” session. Fellow panelists noted that EVs drive down battery costs just through sheer volume. As more people 30

drive EVs, they’ll need a place to charge them, which creates even more potential for solar power.

Kenneth Boyce, principal engineer director of energy and power technologies for UL, also sees connections between EVs and solar. “Perhaps the most important nexus between solar power and EVs is energy storage,” he said, in particular referring to EV batteries being reused to store solar power.

According to IEA’s Global EV Outlook 2016 report, more than one million EVs were on the road in 2015 globally, compared with just hundreds in 2005. The United States alone had about 400,000.

But EV owners have to replace their batteries about every eight years—once

the battery capacity is below 80%. Still, that leaves a lot of life in the batteries, which could be used to store other energies like solar. Using second-life EV batteries for solar is becoming a stronger consideration as the first wave of EV batteries is about to exceed their warranties and require replacement. This could result in a new stream of lower-cost batteries for solar.

“As the population of available EV batteries grows, they can play a key role in the expansion of the energy storage infrastructure,” said Boyce. “Repurposed batteries can be used at utilityscale, commercial-scale and even in community or local power applications, recognizing that the economic profiles may be different across the continuum.”

Using a baseball analogy, Byron Washom, director of strategic energy initiatives at UC San Diego, explained, “We’re not very interested in innovations that may be single or doubles.

But if something comes along that’s a

home run or a grand slam, that’s where we like to focus our interest.”

One of these interests has been second-life EV batteries, which are deployed in several on-campus projects funded through partnerships with NREL, the California Energy Commission and manufacturers.

For example, the university worked with electrical vehicle charging solutions provider EVgo to develop a project that brings EV batteries full circle. The project consists of four EV charging stations, a solar panel roof and two second-life EV batteries to help charge other EVs. The batteries lower the cost of using the charging station, which makes owning an EV cheaper. The project even won an Energy Storage North America 2016 Innovation Award, which Washom took as important validation that his team had picked winning technologies.

TECHNOLOGY

The U.S. had about 400,000 electric vehicles on the road in 2015, according to the IEA Global EV Outlook 2016.

The UC San Diego Strategic Energy Initiatives team doesn’t just test these technologies, but it also provides feedback to manufacturers like EVgo and BMW. “It’s a continual process of nurturing products into commercialization,” Washom said.

The Strategic Energy Initiatives team works to get products to market faster, but a lack of UL listings was slowing the process.

UL recognized the value in UC San Diego’s work and approached the university. The two formed a partnership to accelerate commercialization of second-life EV batteries and other innovations.

“I give credit to UL for inspiring this relationship,” Washom said.

“We both realized we could do our jobs a lot better if we teamed up.”

Cable Management for Solar Installations Revolutionary cable pathways drastically cut installation time lowering construction costs!

Snake Tray products have built-in mounting hardware and nest together for cost-effective shipping and handling.

Developing a new safety standard When it comes to second-life battery certification, UL’s main point of order is developing a safety standard. UL has more than a decade of battery research under its belt, but Boyce said testing EV batteries for reuse is a whole different ballgame.

“The biggest difference in the development of this standard from others is that instead of certifying a product as it is originally produced, the new standard will focus on the processes to requalify a product that has already been in use in a very different application,” he said.

Boyce explained that EV batteries are typically classified for their state of health through initial screening tests. Those not suited for continued-use are weeded out through additional testing to determine what part of a battery pack will be qualified, what will be replaced and what will be recycled.

“The real challenge is finding a method of evaluation for EV batteries that is nondestructive, otherwise we would destroy the battery,” he said.

The new safety standard will be known as UL 1974, which will fit into UL’s existing suite of battery and battery-operated equipment standards for integrating batteries, alongside UL 9540, the standard for the safety of energy storage systems.

TECHNOLOGY “The standard will provide users with the confidence that an EV battery will function effectively as an energy storage device in a residence, commercial facility, microgrid or utility-scale applications,” Boyce said.

Looking to the future Use of second-life EV batteries is still in its beginnings. Even once UL establishes a baseline of safety, it will need to study other important aspects such as how second-life batteries perform.

Economics will also be important. “The cost of a battery remains far and away the most expensive element of an electric vehicle, so there is quite a bit of value tied up there that supports the premise of continued use,” Boyce said. “It is a very dynamic time in the battery sector—prices are trending downward and global production continues to increase.

Only time will tell, but UL is fully committed to providing a path for the safe deployment of these repurposed EV batteries.” SPW

UC San Diego is among the first to attempt this integration of repurposed EV batteries with solar power. Efforts such as these provide important practical insights into the applied use of the technology.

contractors by serving as a single point of contact for accessing modules, racking, inverters, balance of systems and most—if not all—ancillary services necessary to install solar.

As a result of their strategic market position between supply and demand, distributors gain knowledge they can pass onto solar contractors to guide their regular business operations and long-term strategic decisions. By establishing a partnership with solar distributors, contractors gain an extension to their team and access to tools and knowledge needed for achieving a competitive advantage.

How distributors can help Distributors help solar contractors grow their businesses by acting as the fully-managed warehouse for contractors who deliver equipment on-site and job-to-job. Distributors also provide technical guidance on product innovations, design support and permit preparation. In addition, they serve as the top of the sales funnel for solar installers by notifying them of project opportunities and/or providing referrals. Solar contractors also look to distributors as the extension of their market research team, keeping an eye on changes in

36

technology, policy and market forces that could impact their business.

As the partnership grows, both entities can reduce risk, increase sales and profitability and continue to approach the market with confidence.

Choosing a distribution partner Establishing a contractor-distributor relationship can occur in many ways.

Distributors are actively looking for new customers to support, while solar contractors are continuously working to improve their businesses. Whether the conversation begins with a distributor’s prospecting efforts or a solar contractor’s online research, solar contractors should complete their due diligence before entering a relationship with a distributor.

As with any relationship, transparency is key for success. Similar to instilling confidence in the home and business owners they serve, contractors should have coinciding expectations for their distributions partners.

A quality distributor will have a proven-track record, a commitment to set and fulfill accurate expectations and the ability to deliver quality equipment and services. Each aspect cannot stand on its own and is equally as important when choosing partners.

As a solar contractor pursuing a partnership with a distributor, one should have a good understanding of what they consider valuable and important for their business. Preparing a list of pain points, important value adds and business-driven questions before an introductory conversation will ensure everyone’s needs are met.

For example, does the distributor assist with design and engineering? This could make a huge impact on the contractor’s business if in-house technical expertise needs additional support. At a higher level: What would the distributor consider to be its strengths and weaknesses? How long has it been in business?

How many installers has it supported? These exploratory questions will foster a productive conversation and ultimately a transparent, value-driven partnership.

[DISTRIBUTORS]

This is the time for contractors to share candid thoughts on how a distributor can add value to their business and set expectations.

Preparing important documents When a contractor is considering a partnership with a distributor, they should also begin preparing documents that showcase their company. This includes basic business information such as: • Licenses and certificates (contractor’s, business, resale, etc.)

• Financials to ensure eligibility for authorized dealer programs and lines of credit offered by the distributor (P&L statements, tax returns, etc.)

• Current lenders and credit references • Volume installed and project/customer references to support said work

The distributor may also request other information to better understand the contractor’s experience and product preferences.

As with any business partnership, one between a solar contractor and distributor should be mutually beneficial.

Contractors should be offered more certainty and consistency with every transaction, while enjoying the support and positivity such a relationship can award. SPW

refocus on its long-term future, rather than a short-term goal of installing as much as possible before the end of 2016. The extension gives developers much more runway to plan through 2022. The companies SEFA has worked with feel much more relaxed about having sufficient capital and the financing they need to meet their goals. Looking ahead, PPAs, leases and loans will continue to be used to finance solar in 2017. Here’s a close look at how some options are trending, along with the continuing emergence of more commercial financing solutions and solar+storage projects.

Improvements in solar equipment and installation have contributed to a 63% reduction in installation costs since 2011, which is quite remarkable. A solar array has become a much more affordable item. For some customers, the monthly payment on a loan to own the system is about the same as what they’re paying on their energy bill, which is leading to a growth in solar loans. Customers are increasingly wanting to own their system and feel they’re getting 100% of the ITC benefits and the energy produced.

As loans gain popularity, solar leases are dropping from about 80% of the residential market to 60% or less. But this is a positive development because it shows the industry is evolving and able to offer more products to meet the different needs of its customers.

Leasing Solar leasing continues to be one of the most important tools for deploying solar.

It’s convenient; the customer puts next to no money down in return for 10% to 20% savings on their energy bill. Also, because the system is owned by the developer, customers don’t have to worry about maintenance or repairs. The lease was especially key to mass solar deployment in the early days of rooftop solar when installation costs were a lot more expensive.

Commercial solar The C&I market has been the toughest nut to crack, in terms of financing. Commercial projects are all unique with different locations, sizes and off-takers. It’s difficult for investors or lenders to make the economics work. Still, the industry views this as the biggest untapped

market because there are so many commercial rooftops. At SEFA, we spent a lot of time looking at this area and facilitating solutions. Commercial solar installations are good projects and usually find financing eventually; they just have a more difficult time getting financiers interested.

One solution has been the deployment of warehouse financing.

This short-term financing allows the developer to pool projects together and begin them over a period of time.

Pooling projects often attracts some of the larger, more sophisticated financing sources. This short-term financing allows developers to get projects started and operational. Once projects are complete, investors and lenders see them as lower risk, making it easier for developers to refinance the

Business-Financing_1-17_Vs2.indd 39

short-term operational debt into longterm debt or securitization at a lower cost of capital.

Solar+storage In 2015, the industry was looking toward solar ownership with storage as the next frontier for solar, and we’ve started to enter that—it’s amazing what a little more than a year will do!

We are seeing a rapid evolution of battery technology in renewables driven by the EV industry as well as the solar industry because of the need to manage its variable nature.

Right now, it’s not economic for most home or business owners to buy battery technology. But we see solar+storage following a path similar to the early days when solar was expensive and leases helped make it

more obtainable. Different solutions will evolve, such as owning just the solar system and leasing the batteries.

People are working diligently to find solutions to address the whole solar energy picture and its interface with the grid. The techniques to finance equipment have been around for awhile and it’s a matter of rebranding and redesigning them to fit the needs of the solar+storage market. SPW

Key findings Three general observations are worth noting.

First, overall performance across the 154 installers was mixed. A small number of installers demonstrated strong online marketing performance overall, but most had room for improvement in at least a few critical areas—SEO unresponsive websites, lack of email marketing and marketing automation tools and stagnant blogs and social media pages.

prospective customers at scale, with measurable results. But there is no magic bullet—no single activity that companies can check off a list and declare its online marketing efforts done.

Successful online marketing starts with a well-designed, search-optimized website that performs well at a technical level. The website should be updated with fresh, compelling content added to a blog. And companies should continually engage prospective customers through social media and encourage satisfied customers to leave reviews. Some efforts will work better than others; the key is to learn and adjust tactics accordingly.

Second, performance does not always correlate with company size. Many smaller installers stood out from the pack in certain areas.

For instance, one small Massachusetts installer had almost as many consumer reviews as Vivint Solar, and two small California-based installers each had more YouTube videos than SolarCity.

Even small companies with limited resources have found ways to do specific aspects of online marketing effectively.

Finally, there is a lot of low-hanging fruit to grab. In online marketing, small improvements can yield big results. Free (or relatively inexpensive) and easy-to-implement processes can go a long way.

Social media is another free way to connect with current and potential customers. The majority of researched companies had accounts with the major social media properties (for instance, 96% have a Facebook account) and 81 sites had blogs. This is great, but these platforms are only as good as how often they’re updated.

Unfortunately, most companies we evaluated rarely posted anything to them. Take time to assign a person to update social media at least weekly, and blogs even monthly. Or even assign multiple people to the platforms they prefer. Maybe one employee enjoys writing, while another likes to snap photos for Instagram? Alsok don’t forget to link your company’s social media accounts to its website. Only 46% of contractors with a YouTube channel and 38% of those with an Instagram account did this. It’s a missed opportunity to engage more prospects. With

Simple first steps Based on the data we examined, we found some easy ways contractors can improve their online marketing right away.

For example, implementing a content management system (CMS) is an easy way to simplify updating your website. While we found 71% of companies used them, there’s plenty of room for others to jump on board. WordPress is a great choice and is used by 57% of the installers we studied. It’s free, though hosting costs are extra.

Approximately half of all websites are now accessed from smartphones and tablets.

That makes it imperative that your site is “responsive,” meaning it displays correctly on these devices. We found that 79% of the installers researched had responsive websites, which is great, but with so many users accessing your content on a mobile device, everyone should be using a responsive site design template (also called a theme) like WordPress.

It’s also important to understand your website traffic and from where it’s coming.

Google Analytics is a free and powerful tool to understand who visits your website and how they found it. We were glad to see 77% of companies we evaluated use Google Analytics. Just visit google.com/analytics to start.

Why a referral-based solar business makes for the best profits Pamela Cargill Pamela Cargill is principal at Chaolysti

Customer acquisition is a vexing topic for many solar contractors. By looking at what strategies have worked over time, we can determine best practices to build a profitable solar contracting business.

contractors to strike the right balance between growing and staying profitable.

Non-referral strategies and the growth of residential solar

In 2013, NREL and the DOE published a soft cost study and found that non-hardware costs contributed to nearly 65% of a project’s total.

At least 9% of that cost was associated with customer acquisition (exact percentages differed based on geography, business models, etc.).

Since 2013, solar hardware costs have continued to decline, but soft costs have remained stubborn for many. In some regions, especially more competitive areas like Southern California, they have even increased. Customer acquisition remains a perennial challenge for the residential rooftop sector because solar isn’t right for

Non-referral customer acquisition strategies (content marketing, telemarketing, providing a proposal before an in-home consultation and canvassing, for example), have resulted in tremendous growth for residential rooftop solar installers—about 53% in the residential sector since 2005, according to SPV Market Research.

But what is the cost of that growth? High growth rates of 50, 60 or 70% are great, but they also require putting a lot of money into generating non-referral leads. It’s important for 4 4 SOLAR POWER WORLD

everyone, and certain forms of advertising may provide little to no return.

While some factors have affected the solar customer market size since 2015, such as changes to NEM, it’s critical to keep in mind that the total addressable market for rooftop solar is not every person and not even every homeowner.

So how do we reach the addressable market while lowering our acquisition costs?

Steps to lowering customer acquisition costs Step 1: Know your target customer How well do you know your customer and, specifically, the customer that results in a profitable install? The first step to knowing is measuring.

Synchronizing your accounting, estimation and customer information can help you analyze your projects and customers to better understand what types are most profitable and why.

Many marketers look at customer demographics—ownership of the home, age, income, creditworthiness, level of education attained, etc.—to help identify and target their ideal population. For solar, we also have to consider site characteristics, such as home orientation, shade and potential signs of high energy use like pools, AC units or particularly large homes.

During this analysis, it’s also important to understand the maturity of your market. For example, pinning down ideal demographics in emerging markets (such as those in the South and Southeast United States) can seem nearly impossible. Early market buyers bring a different mentality about purchasing a new type of product than those in more mature markets like California or Massachusetts.

Step 2: Focus on referrals first Focusing only on growing quickly may cost you the satisfaction of your customers. When the customer experience suffers, they are less likely to provide a referral.

Referrals are important because, although you may only see a 10 to 25% growth rate, you are likely to be more

dissatisfaction with understanding what would change after they adopted solar.

Instead, provide outlets for consumer education, such as through videos, blogs, seminars and open house events. The consumer can decide how and when they engage with these resources.

Continue to track, nurture and educate any prospective customers you touch through email marketing and a CRM. It may take months or years for some to decide they are ready. When they decide, you want your brand to be top of mind for them.

Don’t forget to keep in touch with customers even after project completion. Reach out on a semiregular basis through timely customer newsletters with tips and tricks on how to read their bill, how to understand their savings and maybe some invitations to fun customer-only events or opportunities. Ask for the referral.

Keep your customers happy and engaged. Respond to their concerns and service requests promptly.

Set up your processes and software project management systems to help support the delivery of great customer experiences. You’ll be well on your way to a strong and profitable referral-based business. SPW

profitable given you have the right process controls in place.

Don’t be afraid to ask for referrals.

Based on my experience, I recommend asking after the installation is totally complete and the customer receives the first utility bill showing solar savings. You’re likely to catch them on a high note.

Step 3: Deliver an excellent customer experience To generate referrals, you must meet or exceed the customer’s expectations. This may sound simple, but making customers feel comfortable involves spending a lot of time educating and communicating with them because they are likely purchasing solar for the first time. They may not have any preconceived notions or experience with the solar buying process or know what to expect when the project is underway. Help them understand what to expect. This means ensuring the expectations you set during the sales process are true, realistic and carried through during project delivery.

Find out how, when and with what method the customer wishes to communicate with your company to learn about project updates. Help them understand the reality of potential delays in construction planning, the approvals necessary and who they can contact when they have questions.

Inappropriate sales compensation, high-pressure sales tactics, onecall closes and dubious promises of savings lead to long-term customer dissatisfaction.

Noted solar market researcher Paula Mints conducted a consumer satisfaction study in 2015 wherein even respondents who claimed satisfaction provided long-form comments indicating confusion and

Is it finally time to add energy storage to your solar services?

It seems as though energy storage has moved from being an “industry buzzword” into something to finally seriously consider.

The technology is there, and utilities are taking notice. And while dedicated residential solar installers might have some experience with a battery or two, most C&I and utility-scale installers have never dealt with large energy storage systems. With the way the industry is going, is it time for solar contractors to add a new service to their installation repertoire?

For most larger developers and installers, the answer is yes, and it’s better to get involved now instead of getting left in the dust. One can go the route of partnering with an established energy storage provider, as California’s

Kelly Pickerel Kelly Pickerel is the managing editor of Solar Power World magazine.

Business-New Markets_1-17_Vs4.indd 46

REC Solar recently did, or starting an in-house storage division, as Swinerton Renewables has done. This is the tale of two companies trying to take advantage of new opportunities.

Partnering up When REC Solar started exploring energy storage installation plans, it wasn’t because of market desperation. Instead, the company wanted to provide its commercial customers with the best options.

“I think we could be successful without energy storage. There is still a big market out there for solar, and storage just doesn’t make a lot of sense for [everyone],” said REC’s John Hostetter, senior director of product management.

“But this allows us to be more successful than we are. There are customers where this is a great opportunity for them.”

Hostetter said REC Solar first started the search for a storage partner five years ago, but the maturation of the market just wasn’t there. This past year, the market seemed to finally catch up.

“More and more customers are talking about it and requesting it,” Hostetter said.

“In a couple years, it’s going to be a major part of the market. If we don’t get ahead of that game, we’re going to miss out.”

In 2015, utility Duke Energy secured a majority stake in REC Solar and brought the commercial solar installer into an exclusive alliance, alongside energy storage provider Green Charge. REC Solar and

REC Solar and partner Green Charge use PV and commercial energy storage solutions at Sonoma Mountain Village, the county's largest solar+storage installation.

[NEW MARKETS]

Green Charge now work collaboratively on solar+storage sales, addressing customer needs on a holistic level.

“Green Charge allows us to have discussions that go beyond just solar projects,” said Garrett Colburn, director of marketing communications and demand generation at REC Solar. “There’s a natural alignment when you form the right alliances. You have similar customers.”

REC Solar and Green Charge don’t work together to bundle solar+storage packages. Not all buyers want cookiecutter options. It’s better to provide them with more options than just a few one-size-fits-all.

“We didn’t go the route of creating our own offering because people don’t want to be told that the one thing we have in our bag is the one thing they need,” Colburn said. “We have this eco-system enabled through Duke. We’re able to at least have the discussion if that makes sense for the customer.”

In November, the two companies announced a plan to build the largest commercial solar+storage project in Sonoma County, California.

The 1-MW system will serve a mixeduse development, including shops and apartments, on a 200-acre campus. The savings and returns on a solar+storage system rather than either a standalone solar or standalone storage system really piqued the development’s interest.

“It’s what differentiates ourselves— positioning ourselves as [having] the scale and the ability to have that larger energy discussion,” Colburn said. “They like to know we’re a serious player that is thinking at that level early on. They want someone who can think long term, into that 30-year schedule.”

Entering into energy storage offerings really came down to providing the best customer service for REC Solar.

“We like to educate ourselves on what the customer’s needs and wants are and then educate the customer on their options and make a recommendation based on their needs

and wants, not necessarily just to push an option that we have,” Hostetter said.

Going solo Utility-scale solar EPC Swinerton Renewable Energy knew it wanted to get involved with storage in a big way once 2017 rolled around. The uncertainty around the ITC extension in 2015 only helped fuel that urgency.

“We saw the trends in the market that 2017 was going to be challenged in utilityscale, with or without the extension of the ITC,” said George Hershman, Swinerton’s senior vice president and general manager. “We knew that in late 2016 we would need to start putting active pieces in motion so in 2017 we could be in a number of different markets that would support the scale of the organization and fill in what was going to be some downturn in the utility market.”

More and more customers are talking about it and requesting it. In a couple years, it’s going to be a major part of the market. If we don’t get ahead of that game, we’re going to miss out. don’t know who the winners or losers on technology are going to be. The marketplace will determine the best technology.”

Swinerton really saw getting involved with storage as a necessary key to survival in the utility-scale market.

“We are a 130-year-old construction company that has evolved over time as markets change. We always look at how we can continue to build a sustainable business model,” Hershman said. “Not in every market will storage be adopted, at least initially. [But] solar+storage is becoming at least an item that utilities and owners are looking at. Having a storage résumé is an important differentiator we saw in this growing trend.” SPW

Luckily for the company, the opportunity came about in late 2016 to assist on an 80-MWh storage project for Southern California Edison—currently the largest lithium-ion battery storage project in the world. A project of that size clearly gives Swinerton a strong résumé to work with.

“Our first storage project is a significant project in the storage market,” Hershman said. “We see it as an opportunity to grow our strength and resources. We didn’t want to be just a utility-scale solar contractor. It was a good short-term play but not a good long-term play.”

The company will now search out large-scale energy storage projects, especially in the active California market.

Business-New Markets_1-17_Vs4.indd 47

“We believe the California market is going to support large-scale storage because of the significant concentration of solar,” Hershman said. “We see our developer clients that are doing traditional solar or wind looking at standalone storage projects. We have a client base that is looking at this as an alternate development opportunity. It’s natural for us to support them directly.”

Rather than partnering with a specific storage technology, Swinerton has chosen to ride the waves of innovation.

“We have stayed technology agnostic in the solar space, and we believe that has served us well,” Hershman said. “We are able to provide the best product offering for any project, because we have a vast array of suppliers and manufacturers that we have relationships with. We look at storage the same way. We

[INSURANCE]

Pete Wilcox Pete Wilcox is the national underwriting officer at Travelers (Edited interview)

Insurance concerns for entering new solar markets When solar installers jump from residential into the commercial or small utility-scale markets, how do their insurance needs change?

[It comes down to] the overall liability that they’re going to have to take on. If they’re doing a bigger system on a rooftop, they really need to know what’s under the roof. Is solar going to have an impact?

[As a residential installer] you’re looking at just the homeowner and their exposure. Now you’re putting solar on a top of a factory that has $200 million under the roof and 1,000 employees. It’s bigger, more expensive. It’s a totally different liability exposure.

When they go to utility-scale groundmounts, a lot of those are in remote areas. You have to think about how to get workers out there. You have to find quality workers. With more hands working on a project, there’s more chance of having a failure, especially when your big thing is to get it up and operational as soon as possible.

It’s a greater financial liability and insurance ties into that. If they can’t prove they’re using the best possible products and the best possible quality control on their installations, cost can be impacted.

4 8 SOLAR POWER WORLD

Business-Insurance_1-17_Vs2.indd 48

What should installers consider when adding new product offerings, such as energy storage?

When they’re going new into it, they’re [hopefully] going to their broker and showing them their plan: Yes, we’re getting into this industry, these are the additional risks that we’ve identified, these are the things we’re doing to minimize that risk to the customers we’re working with. The more knowledge they provide up front, then the broker will feel better about it. It shows they’re not just looking at the revenue stream.

If they’re going to go into battery storage or electrical vehicle chargers, it’s all about where this stuff is located and how it’s being protected from being struck by vehicles, are there enough warning labels on it, are there [user] instructions. Having the OEMs come out and check the installations or [offer] training programs about proper installation [helps get] brokers and customers comfortable with their ability to do the work.

A factory that needs a whole bank of batteries may want to know their chemistry.

Are these a fire hazard to my building? If contractors are getting into a new business, they need to understand all the questions that all the parties are going to have, whether it’s the building owner, the insurance carrier of the building owner or their own insurance carrier.

The more people they make comfortable with what they’re doing, the easier it is to get insurance and better terms and conditions. SPW

Podcast Alert!

Midwest developer promotes solar on national stage

Listen to this and other Contractors Corner podcasts on solarpower worldonline.com

Inovateus Solar South Bend, Indiana

Some may find it surprising that a solar developer based in Indiana is making such an impact on the promotion of solar energy. The Midwest isn’t the quintessential region for solar installations, but the times are a-changin’. As more utilities retire aging coal plants, South Bend’s Inovateus Solar is helping to guide the energy transition to solar.

“It’s exciting to see that what we do—the 40 people here at Inovateus— can have such a big impact,” said president TJ Kanczuzewski. “It’s fun to be part of this energy revolution that’s happening. I couldn’t think of a better profession to have.”

Inovateus Solar started in 2008 as a spinoff of Midwest construction company Inovateus Development. Initially functioning as a distributor, Inovateus Solar quickly shifted to an engineer, then a project manager, then an EPC and finally landed as a developer.

“As we really started to get our foot in the door with some larger companies and utilities, we quickly realized that we had to grow our efforts into being able to provide our customers with other resources,” Kanczuzewski said. “We’ve really come full circle since we kicked off our efforts. It’s been interesting and exciting at the same time to see the

50

Midwestern market really pick up and see several utilities launch solar programs.”

The commercial market is a sweet spot for Inovateus, but the developer is involved with some larger utility-scale projects as well. Currently working on a 60-MW project for DTE Energy in Michigan, Inovateus has been at the forefront of solar’s arrival in the Midwest and expects many more projects going forward.

The major goal for Inovateus Solar, which has been on the Solar Power World Top Solar Contractors list all five years, is to be a Top 5 U.S. solar company.

It’s exciting to see that what we do can have such a big impact.

“We think if we can be the top solar developer in the Midwest, within about 10 years we’ll definitely be in the Top 5 of the country because the Midwest market is really going to become a bigger one,” Kanczuzewski said. Already, Inovateus Solar ranks at No. 11 on the overall 2016 SPW Top Solar Developers list and is the highest-ranking Midwest developer.

The company appears to be on track to its goal.

One way to expand its efforts is to make the company a national name. In a unique partnership, Inovateus Solar has teamed up with IndyCar driver Stefan Wilson to promote solar energy to new audiences.

“I was scratching my head. How does someone in racing, an industry that burns fossil fuels, help promote solar?” Kanczuzewski initially thought. “Stefan quickly put things into perspective. Our purpose as a company is to build a brilliant tomorrow. Stefan’s mission is one to promote sustainability through racing. He really has the foundation in place to talk to the people and take it to the next level.” www.solarpowerworldonline.com

When Wilson drove in the 100th Indianapolis 500 this year, he was racing with Inovateus Solar sponsoring the car.

“We want to help sponsor his racing efforts, but at the same time, he is helping to promote solar energy with the audience he has,” Kanczuzewski said. “One thing we’ve always tried to do at Inovateus is connect ourselves with people who are involved in different industries. With solar, we kind of all preach the same thing to each other within the same industry. That’s great, but we have to get outside of that bubble. For solar to be a mainstream product, you need mainstream folks sharing that story.”

As Inovateus Solar takes steps to spread the gospel of solar energy throughout the Midwest and to bigger national crowds, Kanczuzewski said everyone’s passion for the industry makes the job easy.

“I enjoy the opportunity to make not just a positive impact on the world, but a profound impact,” Kanczuzewski said. “Our core values at Inovateus are passion, engagement, ambition, creativity and esprit de corps— or the acronym PEACE. The solar energy industry gives us the opportunity to really do all of those things 110%.” SPW

Showing solar leadership

Brendan Neagle COO of Borrego Many of your peers on LinkedIn have mentioned your strong leadership skills. You’ve been quoted on Borrego’s blog saying you focus on “empowering other employees to take initiative and to lead and implement their own improvements.” What advice can you offer solar contractors trying to empower and inspire their own teams?

First, listen. Even though I am in the role of the boss, I don’t think of myself as the boss, and I really like to listen to others’ ideas and encourage them.

I try to look for people’s interests and strengths and then encourage those. In that way, employees feel empowered because they can do what they want.

We’ve also had a strong culture of promoting from within, so trying to understand employees’ career paths and goals and trying to make those things happen for them.

A lot of the things I’ve learned about leadership, I also learned through my 12 years of summer camp in New England. I started as a camper and rose through the ranks to be one of the leaders of the different divisions.

It’s a YMCA organization, which is really focused on leadership growth and development.

Even though mainstream solar is still a relatively young industry, some solar professionals have had the opportunity to watch the industry grow and change for decades. Solar Power World has launched a monthly “Ask a Vet” podcast series to highlight these individuals who have spent 10 or more years in the market. Through the podcast and excerpts we will share here in each issue, we hope to provide a platform to share the unique perspectives and insight of these industry veterans.

In our inaugural podcast, we spoke with Brendan Neagle, COO of Borrego Solar, who has spent 10 years with the company and 15 in solar. Neagle’s journey to solar started with studying American civilization and environmental studies at Brown University, working for a beverage distributor, becoming a school teacher and eventually selling residential solar in response to the California Solar Incentive program, which was paying rebates at $4.50/W. Here’s some of what he shared. Listen to the full interview at solarpowerworldonline.com.

What has changed in solar since you started?

When I started in 2001, it was a very small, underserved industry—not very well known. With skyrocketing electric rates, solar incentives being offered and paybacks of five to 10 years, I saw an opportunity. As the industry matured, costs came down, reliability improved and public perception became better.

That’s where we really saw the growth of the commercial and utility market.

Probably the two biggest areas of change have been in cost and reliability. We are literally selling systems for about one-eighth the cost we were selling them when I started.

That’s tremendous. It’s made the technology more accessible. The other side of it is, even with that rapid cost reduction, reliability and confidence in the technology has increased unbelievably. I remember when PPAs were a brand-new, crazy idea. Getting banks to actually finance based on the revenue from kilowatt-hour production from solar was a revolutionary concept.

The reliability and bankability is probably the biggest change I’ve seen, allowing the technology to really reach the mainstream.

What do your children think about solar?

I have a five year old, a three year old and a five month old. My oldest was first exposed to solar panels in our community, pointing them out on the roofs from the stroller. She’s come into work a number of times too and definitely knows “Daddy builds solar panels.”

While she doesn’t know the finer details, she’s also familiar with coal and natural gas plants, and she’ll actually use the term “traditional energy generation” only because she’s repeating what I’d said. But she’ll get the twinkle in her eye and I really think she understands we’re trying to make the world a better place through clean energy.

We’ve also done a lot of projects on schools. I always make a point to say to my staff and to the management group at the schools that putting solar on schools is my favorite application, because not only does it do all the good that any solar project would do, but it exposes the children to the technology in a way that will allow them to grow up thinking solar is normal. They won’t think it’s alternative energy; they’ll think it’s the standard type of energy that was on their school roof. That’s how I empower my employees to get through tough summer sprints on school projects. It’s based on the additive good associated with putting solar on a school, rather than just another application. SPW

designed to offer a higher level of performance with dimensional interchangeability for the “LS” spherical bearing category; a market segment which has remained largely unchanged since the 1950s. “LS” bearings are characterized by being of 3 or 4 piece construction, with an inner ball, an outer ring, and a one or two piece brass, bronze, or cop-per alloy race between.

Since the early 1950’s users of these bearings, which are also mar-keted with a “FLBG”, “RS”, or “VBC” prefix, have had to accept the low strength and poor vibration resistance of these bearings do to the low strength race material.

Aurora’s LCOM bearings incorporate superior materials and manufacturing processes to overcome the performance deficiencies associated with “LS” bearings.

This weakness is addressed in the Aurora Bearing Company’s COM-M series spherical bearings. Like all Aurora inch dimension spheri-cal bearings, these metric bearings all feature a 1 piece steel race way, cold formed around a chrome plated, alloy steel ball for strength, precision and structural integrity.

Aurora COM-M series bearings are available in sizes from 3mm to 30mm., and follow the dimensions of DIN 648 schedule K. Bearings are optionally available with Aurora’s self lubricating AT series ptfe liner, for a smooth, zero clearance fit that is self lubricating and maintenance free.

Maintenance free & cor-rosion resistant rod ends from Aurora The Aurora CM/CW-ET series rod ends

offer a combination of features unique in the rod end industry. Instead of the low strength steels typically found in stainless rod ends, the ET series features bodies made from heat treated 17-4PH material. Not only do they offer excellent corrosion resistance compared to conventional rod ends, they provide greater load capacity, strength and durability as well. The ET series comes standard with Aurora’s exclusive AT2100 PTFE liner. This, combined with a heat treated 440C stainless ball, gives a durable, zero clearance, self lubricating, maintenance free bearing interface to go with the benefits of the heat treated body. Their two piece design allows these high performance features to be exploited at an economical price. The Aurora ET series bearings can be used to enhance the perfor-mance of equipment in wash down, marine, and other environments that require extra corrosion resistance.

COM-M Bearings are stronger choice for DIN ISO 12240-1 applications

Metric spherical plain bearings built to DIN ISO 12240-1 (formerly DIN 648) schedule K often are made with inner races or rings made of brass, bronze or copper. For many low demand applications these bearings have proven to give satisfactory service. However, in applications with high loads and/or high

CPS America launched in 2012 under the umbrella of Chint Group, a $6B energy focused industrial firm - sometimes called the “GE of Asia”. CPS championed 3-phase string inverter architecture in America for commercial and industrial PV applications. The CPS line of 14-60kW inverters earned #1 market share in the USA by 2015 (GTM Research).

Americas leading 3-Phase string inverter maker CPS introduced advanced 3-phase string inverters in 2012 when nearly all DG projects used central inverters. Also, CPS entered the USA when a surplus of incumbent suppliers were already in place (no one wanted another inverter supplier!).

CPS was first to evangelize 3-phase string architecture from standpoint of overall life-cycle costs including soft costs, installed costs (including BoS) and service expenses. In our first year, most resisted changing from central inverters, but today, almost no one uses central inverters for DG projects.

CPS changed the ‘cost’ game in Amercia - CPS supply chain and engineering were able to drive costs down by 25% or more verses other active suppliers. And, year after year, with newer product’s CPS drove costs down further. CPS cost leadership led the way for inverter price reduction from approximately $0.22/W in 2012 to well under $0.10/W today.

Others followed or gave up and exited the industry.

Chint Power Systems America 7060 Koll Center Parkway #318 Pleasanton, CA 94566

CPS is a leader of global supply chain optimization - no other Chinese headquartered inverter firm was successful in American until CPS proved that strong engineering and operations from Asia could be complemented with local USA service, applications engineering, fulfillment and support.

Execution of this global supply chain is hard! But, CPS was first to prove it can be done well. Now others have followed and it is good for the USA solar industry.

[ L E A D E R S H I P I N S O L A R EN ER G Y] Leader of the New Wave of Solar Inverters

There’s a lot of hype in solar, with many products claiming to be revolutionary when the reality doesn’t quite match up.

HiQ Solar focuses on 3-phase inverters for commercial installations, and are quietly changing the way people think about 208 and 480V projects. Our NEMA6 3-phase string inverter is a rugged problem-solver.

Have a difficult roof layout? Unequal strings, are no problem. Harsh conditions?

It’s sealed and ready. A retrofit with no mounting space, or a carport with difficult aesthetic restrictions? Tuck it under the array out of sight. Try the award winning TrueString today.

Based in the heart of Silicon Valley, HiQ Solar is a team of entrepreneurs and industry veterans focused on the needs of commercial rooftops, carports and tracker systems. Where 3-phase string inverters go bigger and bigger for low cost, HiQ has built low cost into a small inverter with features that also lower the total cost of installation. With this approach they won the 2016 “Best Solar Product Innovator” award from Global Energy News, the Intersolar PV Award for 2015 and the NREL “Best Venture” Award for 2014. Is that leadership? We think so.

For decades, S-5!® has produced innovative attachment solutions that make metal roofing the most cost-effective platform for rooftop ancillary attachment.

S-5! has achieved international notoriety by designing easy-to-use products that outlast the roofs to which they are mounted, providing durable, trouble-free service.

Manufactured in the U.S. to the highest quality standards at the lowest possible cost, S-5! clamps are made of compact, lightweight aluminum that is compatible with today’s Al-Zn coated sheet used for roofing. S-5!, with its unique innovations, tested holding strength, metallurgical compatibility, and do-no-harm attachment philosophy is the most trusted name in metal roofing attachment.

Why S-5! Is the Leader in Solar Since S-5!® innovated the first non-penetrating roof clamp more than two decades ago, it has been trusted on over 1.9 million roofs and is recognized as the international authority on ancillary attachment in the metal roofing industry.

Founder and CEO, Rob Haddock, is universally recognized as one of the top metal roofing experts in the world. Frustrated with rooftop ancillary attachments that were difficult to install and performed poorly over time, Haddock transformed the industry with the innovative clamps that employ roundpoint setscrews that compress the seam material against the opposite wall of the clamp creating a mechanical interlock that protects the roofing material rather than penetrating or damaging it.

S-5! is now known as the metal roofing industry’s leading evangelist for the proven advantages of mounting solar panels onto metal roofs. Factors such as compatible service life, durability, and efficiency all contribute to making standing seam roofing and PV a “perfect marriage.” Solar integrators around the globe trust S-5! clamps for permanent attachment of solar panels to metal roofs. More megawatts have been mounted with S-5! than any other attachment product in the metal roofing industry.

The S-5-PV Kit is the easiest, most cost-effective way to install solar panels directly to standing seam metal roofs, automatically providing a grounding path for the module frame. With no lugs or wiring required except to connect one string of modules to another and to ground the system, the S-5-PV Kit provides savings in labor and materials sufficient to pay for the entire attachment system.
