Arizona VA Medical Center Going Solar ! ❂

New Solar Project Will Provide Almost 28 Percent of Facility’s Electricity Requirements When Completed
BY IRWIN RAPOPORT
y next October the Carl T. Hayden VA (Veteran Affairs) Medical Center in Phoenix, Arizona will be enjoying the complete effect of the 18,000 SANYO and Samsung solar panels (via 15 solar inverters at five locations) providing 4.45 megawatts of electricity (seven million kilowatts of clean energy) annually. The panels were placed on newly constructed covered parking spaces, providing shade for more than 1,625 cars at the hospital. This represents the largest solar carport installation in the United States, and it is expected to eliminate 9.3 million pounds of CO2 emissions. Last December the hospital switched on 665 kilowatts of power via Phase I of the project. When completed, the solar panels will provide almost 28 percent of the facility’s annual electricity requirements. The balance of the system is waiting for the interconnections from the utility company and, for the moment, is considered to be the largest solar carport installation - solar photovoltaic (PV) system - in the U.S. The Carl T. Hayden Center, part of the Phoenix VA Health Care System, offers services to more than 80,000 veterans. It has 130 inpatient beds for medical and surgical patients, 80 beds for nursing home patients and 40 inpatient beds for mental health patients. James Larson, the facility’s Energy Manager, worked with the installation company to oversee the project. He notes that the VA is bound by
two mandates – one for renewables and another to reduce energy consumption. An additional investment is being made to reduce energy consumption at the facility by replacing outdated and inefficient systems. “The two are not necessarily linked together, but I tried to combine them,” he says, explaining that the hospital’s original plan called for a covered rooftop application, producing only about 640 kilowatts of power. “But if you put solar on your roofs and you don’t have brand new roofs, you will need to replace the roofs before you replace the solar. That didn’t make sense, especially when we had nearly 30 acres of land that we could use to generate solar and also get the benefit of covered parking for our veterans. You can’t over emphasize the benefit (to the veterans) of having covered parking in the summer in Phoenix - staying out of the sun in Arizona in the summer is the rule.” This led to the solar project being expanded to produce 4.45 megawatts of electricity. The installation company, notes Larson, met the VA’s requirements for the highest amount of covered parking and power generation for the lowest cost. The system cost less than $20 million and the solar power generated is expected to offset approximately $300,000 worth of electricity annually that the hospital purchases. Larsen says,“While it may not appear to make immediate financial sense to go to Arizona [to place solar panels], because our electricity rates are Continued on page 3
