3MECHANICAL/ELECTRICALSPECIFICATIONS

Module electrical ratings are measured under Standard Test Conditions (STC) of 1000 W/m2 irradiance, with an AM1.5spectrum,andacelltemperatureof25°C.Detailed electrical and mechanical characteristics of Canadian Solar crystalline silicon PV modules can be found in datasheets and on www.csisolar.com. The main electrical characteristicsatSTCandatbifacialnameplateirradiance (BNPI)arealso stated oneachmodulelabel. Pleaserefer to the datasheet or the product nameplate for the maximumsystemvoltage.

Under certain conditions, a module may produce more currentorvoltagethanitsStandardTestConditionsrated power.Asaresult,electricalcalculationsanddesignmust beperformedbyaqualifiedengineerorconsultant.

A correction factor should be applied to the open-circuit voltage (see Table 1 below), when determining componentratingsandcapacities.

Table1:Low-temperaturecorrectionfactorsforopencircuitvoltage

selectedmodule(refertothecorrespondingdatasheet) Please contact Canadian Solar’s technical support team foramoreaccuratecorrectionfactorifnecessary.

The module short-circuit current under STC should be multiplied by 1.25×1.25 (i.e., 1.56), when determining appropriate wire and fuse specifications. For bifacial modules, short-circuit current is related to specific installation conditions. It varies with different mounting heightsandmountingsurfaceswithdifferentreflectivity

Consequently short-circuit current of bifacial modules shouldbemultipliedby1.56andthenby1.2.Forbifacial modulesmountedclosetotheroofsurface,nosignificant bifacial gain can be obtained, and therefore, the 1.2 additionalcoefficientisnotapplicableandcanbeignored.

OCPD rating selection should be done per the following guidance, where the minimum OCPD rating possible is determinedbycalculatingtheexpectedmaximumcircuit currentforthePVsystem,andthemaximumOCPDrating constrained by the IEC 61215 and UL 61730 standard requirementsforthecertifiedPVmodules.

Formonofacialmodules,thestringfuseratingshouldnot exceed the maximum string fuse rating listed in the correspondingdatasheet.

For bifacial modules, the following method can be appliedtodetermineanappropriaterating(X):

Minimum string fuse rating ＜ X ≤ Maximum string fuserating.

The maximum string fuse ratings can be found in datasheetsandnameplatesforallthecertifiedCanadian Solarmoduletypes.

TheminimumstringfuseratingforcompliancewithNEC: 2017codeandIEC62548:2016requirementissuggested tobedeterminedasfollows:

Minimumstringfuserating=IscSTC x1.25xMax(1.175, Imppα ÷ImppSTC).

Alternatively, the correction factor for the open-circuit voltagecanbecalculatedusingthefollowingformula:

T (°C) is the lowest expected ambient temperature at the systeminstallationsite

αVoc (%/°C) is the voltage temperature coefficient of the

Imppα = the highest 3-hour current average resulting from the simulated local simultaneous irradiances on thefront and rearsidesofthe PV array accounting for elevationandorientation.

 When installing the modules, ensure the assembly is mounted over a fire-resistant roof covering rated for theapplication.

 Photovoltaic systems composed of UL 61730 certified modules mounted on a UL 2703 certified mounting system should be evaluated in combination with roof coverings in accordance with UL 61730 standard, with respect to meeting the same fire classification as the roofassembly.

 Mounting systems with a System Fire Class Rating, tested in conjunction with ‘type 1’, ‘type 2’ or ‘type 29’ fire-ratedmodules,areconsideredacceptableforusing with Canadian Solar modules, providing the mounting systemdoesnotviolateanyotherrequirementsofthis manual.

 Any mounting system limitations on inclination or accessories required to maintain a specific System Fire Class Rating should be clearly specified in the

installationinstructionsandUL2703certificationofthe mountingsystemsupplier.

ENVIRONMENTALCONDITIONS

 PV modules are intended for use in general open-air climates, as defined in IEC 60721-2-1: Classification of environmental conditions Part 2-1: Environmental conditions appearing in nature-Temperature and humidity.

 It is recommended that PV modules be installed in an environmentwithambienttemperaturerangingfrom40 °C to +40 °C. The 98th-percentile of the module operational temperature should be of 70 °C or lower under any mounting conditions If the application where the 98th-percentile of the module operational temperature of 80 °C is needed, please request IEC 63126Level1moduletypes.

 This environmental temperature range encompasses many locations and installation methods. Annex A provides the reader with modeled PV module temperature examples, at the 98th-percentile dependingonthedifferentworldwidelocations.

 Please consult the Canadian Solar technical support department for more information on the use of modulesinspecialclimates,suchasanaltitudegreater than 2000 m, heavy snow, severe hailstorm, hurricane, etc

 Donot installmodulesnearopenflamesorflammable materials.

 Donotimmersemodulesinwaterorconstantlyexpose modules to water (either fresh or salt, e.g. from fountains,seaspray).

 Exposing modulestosalt(i.e.marineenvironments) or sulfur (i.e. sulfur sources, volcanoes) incurs the risk of modulecorrosion.

 Do not expose modules and their connectors to any unauthorized chemical substances (e.g. oil, lubricant, pesticide,etc.),asmodulesmayincurdamages.

 Canadian solar modules have passed the salt mist corrosion resistance test according to IEC 61701, but thecorrosionmaystilloccurwherethemodulesframe

is connected to the bracket or where the grounding is connected.Should theinstallationlocationbenearthe ocean, Canadian solar recommends stainless steel or aluminum materials be used in the areas with direct contactwiththePVmodules,andtheconnectionpoint should be protected with anti-corrosion measures. For more information, please contact Canadian solar technicalsupportteam.

INSTALLATIONREQUIREMENTS

 Ensure that the module meets the general technical systemrequirements.

 Ensurethatothersystemscomponentsdonotdamage themodulemechanicallyorelectrically.

 Modulescanbewiredinseriestoincreasevoltageorin parallel to increase current. To connect modules in series,connectthecablesfromthepositiveterminalof one module tothenegativeterminalofthenextmodule. To connect in parallel, connect the cables from the positiveterminalofonemoduletothepositiveterminal ofthenextmodule.

 The quantity of bypass diodes in the module junction boxprovidedmayvarydependingonthemodelseries.

 Onlyconnectthequantityofmodulesthatcorresponds tothevoltagespecificationsoftheinvertersusedinthe system. In addition, modules must not be connected togethertocreateavoltagehigherthan themaximum permitted system voltage stated on the module nameplate, even under the worst local temperature conditions (see Table 1 for the correction coefficients thatapplytoopen-circuitvoltage).

 Amaximumoftwostringscanbeconnectedinparallel without using anover-currentprotectiondevice(fuses, etc.)incorporated inserieswithin eachstring.Threeor more strings can be connected in parallel if an appropriate and certified over-current protection device is installed in series within each string. And it shall be ensured in the PV system design that the reversecurrentofanyparticularstringislowerthanthe modulemaximumfuseratingunderanycircumstances.

 Onlymoduleswithsimilarelectricalparametersshould be connected in the same string to avoid or minimize

mismatcheffectsinarrays.

 To minimize risk in the event of an indirect lightning strike, avoid forming loops with the wiring when designingthesystem.

 Modules should be safely fixed to bear all expected loads,includingwindandsnowloads.

 A minimum clearance of 6.5 mm (0.25 in) between modules is required to allow thermal expansion of the framesandmodules.

 Thedrainholesshouldnotbeblocked.

OPTIMUMORIENTATIONANDTILT

 To maximize the annual yield, please calculate the optimum orientation and tilt for PV modules in that specificinstallationsite.Thehighestyieldsareachieved when sunlight shines perpendicularly onto the PV modules

AVOIDSHADING

 Modules shall not be permanently shaded (including partial shading, spot shading, even shading or uneven shading)underanycircumstances.Permanentshading means cells are continuously shaded for extended periods of time, such as installing modules behind a pipeorachimney,etc.Ifadefect(suchasahotspot)is causedduetoapanelbeingimproperlyinstalledinthe shadeorduetopoormaintenance,itwillvoidCanadian Solar’s warranty. Power dissipated in fully or partially shadedcellswillresultinpowerloss,reducedyieldand can cause localized overheating, which in turn may negatively impact the module service lifetime. Permanent shading may cause accelerated ageing of theencapsulationmaterialandplacethermalstresson the bypass diodes. This would void the module’s warranty unless properly mitigated through the use of ModuleLevelPowerElectronic(MLPE)devices.

 Regularmaintenanceisrequiredtokeepmodulesclean. Particular measures should be taken to avoid permanentshadingfromdirtordebris(e.g.,plants,bird droppings,etc.).

 Do not install modules directly behind any object (e.g., tree,antenna,etc.)topreventoccurrenceofpermanent shading.

 Even temporary partial shading will reduce the energy yield. A module can be classified as unshaded if its entire surface is free from shading all year round, includingontheshortestdayoftheyear.

 Foroptimizingthepowergenerationoftherearsideof bifacial modules, obstacles between modules and the mounting ground should be avoided as much as possible.

RELIABLEVENTILATION

 Bifacial modules use direct, reflected, or diffuse

sunlight on the backside to generate additional power. Therefore, bifacial modules are not suggested to be usedinbuildingattachedphotovoltaicsystems(BAPV).

 Sufficientclearanceofat least10 2cm(4.0in)between themodulebottomsideandthesurfaceofrooforwall needs to be provided to allow cooling air to circulate around the back of the module. This also allows condensationormoisturetodissipate.Inparticular,the minimum clearance of any modules applied in BWh area (please refer to Annex A Figure A.2) should be determinedbyCanadianSolar’stechnicalserviceteam.

 According to UL 61730, any other specific clearance required for maintaining a system fire rating should prevail. Detailed clearance requirements pertaining to system fire ratings must be provided by your racking supplier.

5.1MODULEWIRING

CORRECTWIRINGSCHEME

 Cable management scheme should be reviewed and approvedbytheEPCcontractor.Requiredcablelengths should be cross-checked and account for tracker structure particularities e.g. bearing house gaps. If longercablesoradditionaljumpercablesarerequired, please contact Canadian Solar’s sales representative in advance.

 Ifthecablesaresecuredonthebacksideofthemodule by locating tapes. Please remove it from the module during installation. It is recommended to remove glue remainingonthesurface,ifthereareany.

5.2GROUNDING

 Forgroundingrequirements,althoughthemodulesare certified to Safety Class II, we recommend them to be grounded and that module installation should comply withallapplicablelocalelectricalcodesandregulations. Minimum size of equipment grounding conductors for ground raceway and equipment from NEC 690.8(D) should be considered. Grounding connections should be installed by a qualified electrician. Connect module frames together using adequate grounding cables: we

recommend using 4-14 mm² (AWG 6-12) copper wire. Holes provided for this purpose are identified with a grounding symbol (IEC 61730-1). All conductive connectionjunctionsmustbefirmlyfixed.

 For grounding requirements in North America, a modulewithexposedconductivepartsisconsideredto comply with UL 61730 only when it is electrically grounded in accordance with both the instructions presented belowand therequirementsofthe National Electrical Code. Any grounding means used with CanadianSolarmodulesshouldbeNRTLcertifiedtoUL 467 and UL 2703 standards. Please consult our technicalserviceteamfortheformalapprovalprocess.

 Do not drill any extra ground holes for convenience as thiswillvoidthemodule’swarranty.

 All bolts, nuts, flat washers, lock washers and other relevant hardware should be made of stainless steel, unlessotherwisespecified.

 CanadianSolardoesnotprovidegroundinghardware.

 Canadian Solar material selection substantially limits potentialinduceddegradation(PID).ShouldfurtherPID suppression be desired for the project, negative grounding is still an optional measure for PID mitigation and for optimal performance Anti-PID function of inverters is another option. Please consult yourinvertersuppliersformoreinformation.

 The grounding method described below is recommendedforCanadianSolar

GROUNDINGMETHOD:BOLT+TOOTHEDNUT+CUPWASHER.

To fix the wire between the flatwasherandcupwasher, place the cup washer (concave side up) between theframeandthewire. Then tighten the bolt usingthetoothednut.

 AgroundingkitcontaininganM5(3/16")SScapbolt,an M5 (3/16") SS flat washer, an M5 (3/16") SS cup washer, and an M5 (3/16") SS nut (with teeth) is used to attach copper grounding wire to a pre-drilled grounding hole ontheframe(seeimageabove).

 Place the wire between the flat washer and the cup washer. Ensure that the cup washer is positioned

between the frame and the wire with the concave side up to prevent galvanic corrosion. Tighten the bolt securely using the SS toothed nut. A wrench may be usedtodothis.Thetighteningtorqueis3-7Nm(2.2-5.2 ft-lbs).

 For bifacial modules, mounting rail designs should be such to allow easy access to the grounding holes locatedonthelongsideoftheframe,inordertoenable theequipmentgroundingfunctionwhenrequired.

6MOUNTINGINSTRUCTIONS

Theapplicableregulationspertainingtowork safety, accident prevention and securing the construction site must be observed. Workers and third-party personnel shall wear or install fall arrest equipment. Any third party need to be protected against injuriesanddamages.

 The mounting design must becertified by a registered professional engineer. The mounting design and proceduresmustcomplywithallapplicablelocalcodes andrequirementsfromallrelevantauthorities

 The module is considered to be in compliance with UL 61730 and IEC 61215/61730 only when the module is mounted in the manner specified by the mounting instructions included in this installation manual or whenspeciallyapprovedbyCanadianSolarinwriting

 The system designer and installer are responsible for load calculations and for proper design of support structure.

 Themechanicalload testsinthismanualareonlyvalid whencoupledtomountingandsupportstructuresthat are capable of withstanding equal or greater mechanical loads. The mounting system supplier is responsible for the strength and stability of the mounting structure, which must meet the requirementsoftherelevantdesignspecifications.

 The loads described in this manual correspond to test loads. For installations complying with UL 61730 and IEC 61215/61730, a safety factor of 1.5 should be applied for calculating the equivalent maximum authorized design loads. Project design loads depend on construction, applicable standards, location and

local climate. Determination of the design loads is the responsibility of the racking suppliers and/or professional engineers. For detailed information, please follow local structural code or contact your professionalstructuralengineer.

 Itisknownthatloaddistributiononthemoduleareais not balanced. Wind and snow loads are unevenly distributed onthemodule’s surface,and such must be considered in the definition of the PV module design load and the respective restrictions to apply for the mountingsupportsystem.Thetestloadvalueshownin this manual is the uniform load. The maximum allowable unbalanced design load (Pmax) must be lowerthan0.8(unbalancedfactor)×Testload.

 During installation, it is necessary to inspect the componentsbelowthemoduletoensurethatthereare no zinc slag protrusions or burrs on the surface, in ordertoavoiddamagetotheglassorbacksheet.

3) When using serrated bolts and/or serrated nuts, it is not necessary to attach spring washers, but in order to ensurethestabilityoftheconnection,werecommendthe use of nuts with anti-loosening function for installation During tracker installation, ensure that the outer diameter of the M6 serrated bolt falls between 16~16.8 mm. If not, insert a 16 mm outer diameter washer betweenthemoduleandthebolt Fastenersmuststrictly follow the relevant standards to ensure that the quality and performance. The grounding connectivity check of theserratedboltstogetherwiththemoduleframeis out of the scope of this manual and is sole responsibility of the racking supplier and installer, following local regulations.

 The laminate of the PV modules will sink downward to varying degrees due to gravity, with the center of module being the maximum deflection position. While using bolting or clamping mounting method or insertion system, the maximum allowable deflection (ΔL shown in the picture below) is 20 mm (in the absenceofexternalforcescausedby,forexample,wind and snow). Note that applying pressure to the module surface during storage, transportation and installation willleadtomoreseveredeflection.

6.1MOUNTINGMETHOD:BOLTING

 Themechanicalloadtestwiththesemountingmethods wereperformedaccordingtoIEC61215.

 Modules should be bolted to supporting structures through the mounting holes in the rear frame flanges only.

 Each module must be securely fastened at a minimum of4pointsontwooppositesides

Suitable bolt length should be chosen based on actual module frame height. For double glass module with 30 mm frameheight,ourrecommendedmaximumboltlength is 20 mm in order to properly insert the bolts through themountinghole.Thesystemdesigneris responsible to check that the racking supplier specified bolt length complies with above requirement and will not affect installation.

 In areas with heavy wind loads, additional mounting points should be used. The system designer and the installer are responsible for correctly calculating the loadsandensuringthatthesupportingstructuremeets alltheapplicablerequirements.

8MODULECLEANINGGUIDELINES

This manual covers the requirements for the cleaning procedure of Canadian Solar photovoltaic modules. The purposeofthesecleaningguidelinesistoprovidegeneral informationforcleaningCanadianSolarmodules.System users and professional installers should read these guidelinescarefullyandstrictlyfollowtheseinstructions.

Failure to follow these instructions may result in death, injury or damage to the photovoltaic modules. Damages induced by inappropriate cleaning procedures will void CanadianSolarwarranty.

SAFETYWARNING

 Cleaning activities create a risk of damaging the modules and array components, as well asincreasingthepotentialelectricshockhazard.

 Crackedorbrokenmodulesrepresentanelectricshock hazardduetoleakagecurrents,andtheriskofshockis increased when modules are wet. Before cleaning,

thoroughly inspect modules for cracks, damage, and looseconnections.

 The voltage and current present in an array during daylight hours are sufficient to cause a lethal electrical shock.

 Ensure that the circuit is disconnected before starting the cleaning procedure, as contact with leakage of electricallyactivepartscanresultininjury.

 Ensure that the array has been disconnected to other activecomponents(suchasinverterorcombinerboxes) beforestartingwiththecleaning.

 Wearsuitableprotection(clothes,insulatedgloves,etc.).

 Donotimmersethemodule,partiallyortotally,inwater oranyothercleaningsolution.

 Rear side cleaning of the modules is not required, if cleaningtherearofamoduleisdesired,careshouldbe taken to ensure there is no damage caused to the module,especiallythesoftsurfaceofthebacksheet,by simplyclearing the contaminant byhand orwithasoft sponge.

HANDLINGNOTICE

 Useapropercleaningsolutionandsuitablecleaning equipment.

 Donotuseabrasiveorelectriccleanersonthe module.

 Particular attention should be taken to avoid the module rear glass or frame coming in contact with sharp objects, as scratches may directly affect product safety.

 Do not use abrasive cleaners, de-greasers or any unauthorized chemical substance (e.g. oil, lubricant, pesticide, Gasoline, white flower oil, active oil, mold temperature oil, machine oil (such as KV46), grease (such as Molykote EM-SOL, etc.), lubricating oil, antirustoil,stampingoil,butter，cookingoil,propylalcohol, ethyl alcohol, essential oil, bone-setting water, Tianna water, mold release agent (such as Pelicoat S-6, etc.), glue and potting glue that can generate oxime gas

(suchasKE200,CX-200,Chemlok,etc.),TBP(plasticizer), cleaning agents, pesticide, paint strippers, adhesives, antirustagent,disincrustant,emulsifyingagent,cutting oilsandcosmetics,etc.)onthemodule.

 Do not use cleaning corrosive solutions containing hydrofluoric acid, alkali, acetone, or industrial alcohol. Only substances explicitly approved by Canadian Solar areallowedtobeusedforcleaningmodules.

 For cleaning methods using rotating brush, please consult with Canadian Solar's technical support before using.

 Dirt must never be scraped or rubbed away when dry, as this will cause micro-scratches on the glass surface. The module damage due to improper dry cleaning methodwillvoidCanadianSolar’swarranty

 Improper cleaning equipment design may cause localizedheavyloadsontothemodule.Localizedheavy loadsmaycauseseveremicro-cracksatcelllevel,which in turn may compromise module reliability and void CanadianSolar’swarranty.PleaseconsulttheCanadian Solartechnicalsupport department for informationon the use of cleaning solutions and loading specifications..

OPERATIONPREPARATION

 Noticeabledirtmustberubbedawaybygentlecleaning implement (soft cloth, sponge or brush with soft bristles).

 Ensurethat brushesoragitating toolsare not abrasive toglass,EPDM,silicone,aluminum,orsteel.

 Avoid cleaning during the hottest hours of the day, in ordertopreventthermalstressonthemodule.

CLEANINGMETHODS

MethodA:CompressedAir

Canadian Solar recommends cleaning the soft dirt (like dust) on modules just with air pressure. This technique canbeappliedaslong asthemethod isefficient enough consideringtheexistingconditions.

MethodB:Wetcleaning

If excessive soiling is present on the module surface, a

non-conductive brush, sponge, or other mild agitating methodmaybeusedwithcaution.

 Ensure that any brushes or agitating tools are constructedwithnon-conductivematerialstominimize risk of electric shock and that they are not abrasive to theglassorthealuminumframe.

 If grease is present, an environmentally friendly

cleaningagentmaybeusedwithcaution.

 CanadianSolarrecommendsthefollowingtobeused:

 Waterwithlowmineralcontent

 NearneutralpHwater

 The maximum water pressure recommended is 4 MPa(40bar)

ANNEXA:GUIDANCEONMODULETEMPERATUREFORSEVERALLOCATIONS

 The operational temperature of a PV module changes duringthedayandalsofromdaytodaythroughoutthe year. The 98th-percentile temperature represents the temperature that is larger than 98% of all the temperatures, and consequently it is met or exceeded only2%ofthetime.

 The 98th-percentile temperature is to be determined from measurements taken on hourly-basis, or even more frequently. For a standard year, the 98thpercentile temperature would be met or exceeded 175.2hours.

 The operational module temperature is influenced by the environmental temperature but also by how the module is installed (e.g. mounting distance to roof, array size, array spacing and anti-nesting features), as it may allow a more efficient ventilation. The graphics below from IEC 63126 show this influence, the maps

presented here are a general guidance and assumed conservative, please contact your local sales representativeforfurtherinformation.

 The operational temperature is influenced by the minimum distance between the module bottom and thesurfaceofrooforwall.Thedistanceisrelatedtothe climate. Figure A.2 shows climate area distribution of the Köppen climate types for the period from 1901 to 2010. In any climate regions except for BWh area, the minimum distance should be 10.2 cm (4.0 in). If you want to determine a specific distance on your project located in the BWh climate area, please contact Canadian Solar’s technical service team. For more information about Köppen climate types, please refer tohttp://hanschen.org/koppen

I General

Please carefully follow this manual to learn how to correctly install the GameChange Solar Max-Span™ Ground System. The Max-Span™ Ground System is engineered and tested to withstand wind and snow loads to specification when installed properly. Failure to precisely follow the install manual and to install the racking system properly may decrease the performance of the installation and will void the warranty.

This is the generic manual and it includes all components utilized in all variations of the Max-Span™ Ground System Please refer to your particular permit/layout detail sheets and bill of materials for the specific components for your system as some components may not be required.

II Safety Precautions and Responsibility of Installer

The installer is responsible for the following:

 Following all instructions in this Install Manual

 Utilization of only qualified personnel

 Using only GameChange parts. Using other parts to complete the installation as substitutes may void the warranty.

 Making sure the ground structure (notably in the case of a capped landfill) can support the loading resulting from the Max-Span™ Ground System

 Following all safety procedures as outlined in this Install Manual, both for mechanical and electrical aspects of the solar PV array installation

 Following all safety instructions that are required by relevant local, regional and national organizations

 Materials are packaged in optimal manner to protect components. Do not un-package until time of installation. Un-packaging and restacking may cause damage to components.

General safety precautions:

 Plan for safe practice during any installation activity with respect to hazards from tripping, falling, lifting, repetitive stress, and any overhead or electrical hazards. Refer to OSHA safety guidelines.

 Metal components often have sharp edges. Handle carefully! Wearing gloves is good practice.

 This document is not prescriptive regarding safety and does not purport to address all the safety concerns that may arise with its use. Contractors should become familiar with all applicable safety, health and regulatory requirements before beginning work.

 Electrical safety notice – The Max-Span™ Ground System is a mechanical system and contains no “live” parts. Mechanical installers and electricians should coordinate in order to ensure that all personnel are aware of electrical hazards that may result once panels have been placed on the racking structure.

 Build rate – Estimated mechanical installation rate (racks and panels per day) for an array consisting of commercial-class modules installed with the Max-Span™ Ground System and assuming a well-equipped five-person crew working 8 hours / day with full task interchangeability: approximately 227 panels and racks per day. 15 men install 1.05 MW per week with 300 watt modules.

 Field modifications and Work arounds – Unauthorized field modification and workarounds of Gamechange components or assemblies may affect GameChange warranty coverage. Provide marked up drawings for Gamechange’s review, comment and approval prior to attempting. Installers laying out or installing arrays may encounter undocumented or unexpected obstacles requiring a work around. Since PV arrays are intended to be primarily regular and repeating structures, work arounds should be brought to the attention of GameChange personnel prior to being done. If approved by GameChange, they should be noted on working drawings.

Suggested driver torque

1/4-inch hardware (7/16-inch driver), use 6 ft-lbs

3/8-inch hardware (9/16-inch driver), use 20 ft-lbs

3/4-inch hardware (1 1/8-inch driver), use 140 ft-lbs

 All regional safety requirements shall be followed when installing the Max-Span™ Ground System. All equipment/tools shall be properly maintained and inspected prior to use. This installation manual is intended for use by professional installers with a working knowledge of construction principles. If the install manual is not followed completely the warranty may be voided and the solar system may not operate optimally.

III Materials and Tools Required

The following tools are required for the installation of the Max-Span™ Ground System:

 String line, 48 inch long level and 30 foot tape measure

 Anti-seize may be beneficial to prevent galling for bolts used to mount panels, but is not required

V Assembly and Installation Instructions

Step 1: Placement of the Posts – Post Installation

1.0 Measure the footprint of the array according to the installer’s design and site plan.

2.0 Find the edges of the array according to provided design.

3.0 Drop a string line on the southern edge.

4.0 Mark Post Locations with locator nails according to array plan starting at south-east corner of array -Make sure define distance between foundations is measured from center of post to center of next post along the ground (not from plan view). Otherwise foundation locations will creep if there is rolling terrain since plan view does not factor in dimensions differences caused by terrain. This could make purlin attachment more difficult.

5.0 Install first Post to the proper height above the ground

5.1 There is an adjustment range given by GameChange for posts with a minimum embedment depth governing on one side and the distance for ground clearance requirement on the other.

5.2 This is typically from 4 to 8 inches.

5.3 It is good to vary embedment depth from minimum to maximum allowed on this range in order to align tops of piles in a flat or relatively smoothly sloping fashion as per the ground being flat or sloping.

6.0 Make sure the two longer sides (approximately 6-inch) face East-West, and the open side faces north North↑

7.0 Make sure next Posts are installed at specified distances from marked locations:

7.1 East-west +/- 1 inches The racking system allows for +/- 2 inches but this will make more adjustment of purlins necessary and slow down installation

7.2 North-south +/- 1 inch

8.0 Make sure posts are squared to within +/- 1 degree to the azimuth of the array

9.0 Tops of the posts are leveled to be at a consistent height or slope depending on the topography of the land (with a tolerance of optimally +/- 1 inch). Note that embedment depth will vary. GameChange provides range of embedment depth to allow for this. Be careful to always meet minimum embedment depth.

10.0 Make sure post is plumb, optimally +/- 1 degree so long as:

10.1 Not more than +/- 1 1/2 inches on east to west direction at top of post (from the proper post location marked on ground). The racking system allows for +/- 2 1/2 inches but this will make more adjustment of purlins necessary and slow down installation)

10.2 Not more than +/- 1 inch north to south direction at top of post (from the proper post location marked on ground)

V Assembly and Installation Instructions

Step 1: Placement of the Posts – Refusal Instructions

Inform Game Change immediately if refusal is encountered when driving posts. Refusal is defined as a blow count of 10 or more per inch (120 blows per foot). Refusal of posts shall be addressed as follows:

Option 1 – Use post at shallower embedment depth

a) Based on the embedment of the post at time of refusal and the location of the post relative to the array, GameChange engineering staff may determine it to be acceptable to leave the post at the shallower embedment depth. If instructed by GameChange engineering staff, cut the top of the post to the appropriate height and field drill bolt holes for connection to the beams per post drawings.

b) Pull testing may be required to confirm the post at the shallower depth has sufficient resistance to the design uplift and lateral forces. Pull test procedures, including test loads, will be provided by GameChange engineering staff.

Option 2 – Install post in Aggregate Base Course

a) Pull Post out using a crane attached to the topmost slots (or equivalent method)

b) Drill hole for Post using a 10” drill to the depth prescribed for Post embedment depth within tolerances.

c) Fill hole with aggregate base course. Depending on site conditions, this method may not be applicable, or compaction of the aggregate fill may be required. Consult GameChange engineering staff for more information.

d) Drive post at original location, through aggregate, in accordance with typical post installation instructions above.

Option 3 – Install shorter post in concrete pier

a) Pull Post out using a crane attached to the topmost slots (or equivalent method)

b) Drill hole for Post using a 12” drill to the depth prescribed for Post embedment depth within tolerances.

c) Insert Post into drilled hole and hold plumb. Temporary wooden bracing supports may be used for this.

d) Fill with 4,000 psi concrete, in consultation with GameChange to amount of concrete and method of installation.

Installing Posts using drill and concrete pouring method to ensure proper Post top alignment:

 Attach tape to the drill bit (for pre-drilling holes for pile holes to be filled in with concrete) so that the distance from the tape to the bottom of the drill bit is the same as the height of the post.

 Set a stake at each end of a row line.

 Attach a string (or aircraft cable and use come-alongs to keep taught) from one stake to the other, and make sure it is at the proper post height above the ground.

 Dill holes vertically and plumb until bottom of the tape is level with the string.

 Remove drill and place post in hole.

 This will align every post to a consistent slope

 Embedment depth will vary, make sure minimum embedment depth meets GameChange requirements. Please consult with GameChange for more detail.

Deformation at the top of the piles rarely occurs, and typically only when piles are driven into rock, and is minor and easily remedied. Deformation could cause problems for the installation of the NS Beam. If any deformation at the top of the piles occurs during installation:

a) If mushrooming is locally isolated above any slots or features and within 1/8 inch of the original drawing dimension (4 15/16”), use a hammer (or equivalent equipment) to reshape the top end of the Post back to within 1/16 inch of the original drawing dimension.

b) If piles are deformed more than 1/8 inch then consult with GameChange regarding re-use.

If there is any cracking of galvanized coating on piles make sure to wire brush then paint area with zinc rich paint.

Step 3: Purlin Assembly

1.0 EW Purlins attach to NS Beams using:

1.1 Two 3/8-inch bolts

1.2 Two serrated flange nuts

1.3 One Purlin Washer (must use Purlin Channel Washers for 16 gauge Purlins)

1.4 One Wide Beam Washer

2.0 EW Purlins should be installed facing uphill or downhill as shown in drawing set for each individual system provided as by GameChange.

3.0 Post distances may vary due to site conditions or Post installation variances, therefore do not install all table purlins first. If you install all table purlins first, you will likely need to go back and take some of these off and reinstall if connector purlins do not reach. It is better to install only a few table purlins ahead and then go across the row using table then connector purlins as you go.

4.0 Attach first EW Purlin at center holes on the southernmost position to the first and second NS Beams using center set of holes for EW Purlin attachment.

4.1 Hardware attachment sequence:

4.1.1 Insert 3/8-inch bolt through Purlin Washer nearest to EW Purlin wall, EW Purlin, NS Beam, and Wide Beam Washer. Make sure Purlin Washer is pushed up tight against the wall of the Purlin, this is important.

4.1.2 Attach 3/8-inch flange nuts below NS Beam

4.1.3 Insert 3/8-inch bolt through EW Purlin furthest from EW Purlin wall, NS Beam, and Wide Beam Washer

4.1.4 Attach 3/8-inch flange nuts below NS Beam

4.1.5 Finger Tight on hardware

4.1.6 After Panels mounted and Purlins properly aligned, tighten hardware to specification, using driver to turn bolt head.

4.1.7 Alternatively bolts may come up and flange nuts be above purlin

4.2 Then, noting the length of the connecting EW purlin, attach the second southernmost EW Purlin to the third and fourth NS Beams

4.3 For completing EW Purlin installation on tables:

4.3.2 Using the tape measure to confirm the table is square(by cross measuring or golden 345 triangle.

4.3.2.1 May need to tighten bolts to hold the table square.

4.3.3 Install the second EW Purlin and the fourth EW Purlin.

4.3.4 Use a tape measure or t-square to make the second and fourth EW Purlins are square with the first and third.

Attach connector EW Purlin to between the table EW Purlins. There will be a nominal drop of 1/8 to 1/4 inch from one purlin to the next, which will result in a small corresponding drop from one panel to the next at these junctions. This is normal for connecting systems and is not a shading or functional issue. Try to attach slots at center if possible. This will make for better spaced panel install.

4.4.1 Hardware attachment sequence:

4.4.1.1 3/8-inch bolts (or serrated head bolts),

4.4.1.2 washers (on either side, one under the bolt head and another under the nut) and

4.4.1.3 serrated flange nuts.

4.4.1.4 Alternatively bolt direction may be reversed.

Connecting purlins allow for articulation to handle east-west slopes of up to 8%

4.5 Repeat for all table EW Purlins and connecting EW Purlins

4.6 Make sure to attach the alternating table EW Purlins and connecting EW Purlins starting at one end of row and continue to the other end of the row.

4.7 Do not attach table EW Purlins at several points along the row in isolated table format or you may not be able to utilities all of the EW adjustment features provides as easily as if you start on one end and work your way across.

Step 4: Additional Support Attachments

Attaching the Bend Strap

1.0 Bend Straps shall be installed on the underside of the EW Purlins approximately midway between two adjacent Beams. Use 3/8-16 hex bolts and serrated flange nuts. Torque to specification

Attaching the Roll Ties

2.0 Roll Ties shall be installed on the EW Purlins approximately midway between two adjacent Beams (one on either side of the Bend Strap) Assembly drawing will identify where the Roll Ties are to be installed. One Roll Tie will be installed from the top of the southern Purlin web to the bottom of the northern Purlin leg. The other Roll Tie will be installed from the top of the northern Purlin web to the bottom of the southern Purlin leg. Use 3/8-16 hex bolts and serrated flange nuts The Roll Ties must be taut, this is very important Torque to specification.

Attaching the Roll Straps

3.0 Roll Straps shall be installed at both ends of first and third EW Purlins to the Beams. Use 3/8-16 hex bolts and serrated flange nuts. The Roll Straps must be taut, this is very important. Torque to specification. Bolts through purlin may be installed in either direction with flange nut on either side, however bolts through beam must have head above beam and Flange nut under Beam. Torque to specification.

Attaching the Purlin Angle

4.0 Purlin Angles (if required) shall be installed on the underside of the EW Purlins at the holes next to the NS Beams on the upper EW Purlins, holes near the center of the lowest EW Purlin, and the respective holes that line up for the 2nd and 3rd Purlin. Use 3/8-16 hex bolts and serrated flange nuts. Torque to specification.

Step 5: Module Attachment

Panel Mounting Hardware:

 Stainless steel:

o Hex bolts - 1/4-20 x 3/4 inch long

o Flange nuts (1/4-20)

o External tooth star washer

1.0 Attaching first panel to EW Purlin through mounting holes in EW Purlins nearest to NS Beam:

1.1 Place star washer at one location per panel inside panel frame.

1.2 Insert hex bolt through the EW Purlin, through the mounting hole in the back of the panel, then through the star washer.

1.3 Attach with a flange nut on end of bolt inside panel frame over star washer.

1.4 Tighten bolt to specification.

1.5 Repeat 1.1 through 1.4 for three more bolts for each panel without using star washer.

Bottom mount method: Portrait configuration:

Alternate Panel Mounting Method: If panel mounting hole diameter or slot width is 0.28” or less, the orientation of the bolt and nut can be flipped such that the stack-up order from top to bottom is: hex bolt head, star washer, panel frame mounting hole, EW Purlin mounting hole, and flange nut.

2.0 Repeat for all panels

3.0 For bottom mount attachment of panels GameChange typically provides slotted panel mounting holes to enable panel adjustment in case purlins are not perfectly aligned due to rolling or otherwise uneven ground situations.

4.0 It is the customer’s responsibility to make sure to follow panel spacing guidelines if any are given by panel vendor in their specification sheet or elsewhere, otherwise panel warranty could be voided. In all cases make sure panel spacing is the greater of 1/8 inch or the minimum called out by the panel vendor. This will allow for thermal expansion of panels. GameChange systems typically enable ¼ inch panel spacing if aligned properly.

4.1 Spacing between panels can be set by placing a temporary spacer such as bolt shaft or plywood of same thickness as required for panel spacing between panels while they are being installed. This spacer should be removed after panel installation is complete.

Step 6: Wire Management

It is the installers responsibility to install wiring properly. Care should be taken fasten wire firmly in place to prevent movement or chaffing against metal parts over time. Wires should be checked on a routine basis to make sure they remain firmly attached and in place.

IV Assembly and Installation Instructions

Step 7: Grounding

The modules and EW Purlins are all bonded together across the entire row, East and West.

To achieve grounding of the system, GameChange recommends installing Cooper, Burndy, or Eaton UL approved grounding lug(s) with 1/4-inch bolts as in accordance with NEC Article 690 to the Post below the last EW Purlin which has panels attached to it which are to be bonded, using 8 gauge copper wire.

The Purlin to Purlin bonded connection is rated for up to 25 amps. Therefore, conductors with expected currents greater than 25 amps may not be installed on the racking system without installing additional grounding measures.

The entire system needs to be grounded from a single point to an appropriate grounding source.

**Please confirm with an electrician, as this is their responsibility**

In case of a configuration where there is a break in the array, UL 2703 listed jumpers (e.g., Burndy WILEYBRAID) may be used to bond one segment of the array to the next (only one jumper in between two tables). Install jumpers via unused or field-drilled holes on the Purlin, Beam, or Post, and using UL 2703 approved attachment methods.

VI System Overview

The Max-Span™ Ground System is a simple, affordable, easily installed ground-based solar mounting system. Components are made from galvanized and stainless steel. Max-Span™ Ground System may be installed on solar arrays of up to 200,000 solar panels each (approximately 50 MW). Maximum panel size for the system shall be 45 x 82 inches. Slopes up to 10% are allowable under all normal conditions for continuous systems, and up to 30% for table systems only in consultation with GameChange personnel.

VII Materials, Storage and Warranty

All materials are made from non-corrosive materials, galvanized, magni coated or stainless steel, with a product warranty of twenty (20) years.

Suggested driver torque

3/8-inch

Make sure to install system within several days of receipt of components. Storage of components in a damp or wet environment can lead to white rust on galvanized parts as well as other damage on other protective coatings which can lead to accelerated corrosion of components, and void the warranty. Galvanization is especially prone to white rust when components are still bundled because the zinc coating requires airflow over its surface to establish its protective patina, otherwise water can cause corrosion of the zinc and it has no protection against it in enclosed spaces, such as those between parts that are bundled.

VIII Site Selection

 Proper preparation of surface must be ensured for a well-performing system to be installed. For continuous racking without breaks, ground must be at an east-west slope not to exceed 5 percent to minimize east /west shading from panel to panel.

 Grading of the ground on the installation area is the responsibility of the customer and should be completed properly to enable the slope tolerance for the Max-Span™ Ground System.

General guidelines include:

 Choose a clear area free of shading

 Suggested ten (10) foot border surrounding array

IX Preventative Maintenance

Proper preventative maintenance must be conducted or warranty may be voided. After installation of the Max-Span™ Ground System, installer must annually monitor for any surface rust that may occur over time due to scraping of the components or for any other reason. While the extensive galvanizing protection should minimize any such rusting, it is essential that preventative maintenance be performed annually to include:

 Identifying any rust areas

 Wire brush the rust area to remove all rust

 Coat the area with 70%+ zinc rich or equivalent field life paint

 This step is not required if rust is limited to edges which were cut during fabrication

After extreme wind turbulence (in excess of 80% of design wind speed), and on an annual basis, an inspection must be done for mechanical movement (which could also be due to any reason including thermal expansion and contraction). Any mechanical movement must be rectified. Torque settings must be checked for all hardware. All Clips shall be checked to make sure there is no gap between the side of the Clips and modules.

It is estimated that two qualified persons should be able to properly inspect and maintain racking for approximately 1,000 panels per day.
