SunPower Corporation, a leading manufacturer of solar panels, willsoon improve Arizona’s already impressive solar power portfolio. Thecompany has started construction of a 3.5-megawatt (MW) solar energysystem atop the Macy’s fulfillment center in Goodyear, Arizona. Whencompleted, it will be the largest single-rooftop solar energy system inthe U.S., according to a company statement.
The system is made up of SunPower’s E19 panels, which, according toSunPower, are the most powerful panels on the market today. They will be mounted on the SunPower (R) Solar Roof Tile system, the company’s newroofing solution that promises to roughly double the amount of energygenerated per square meter compared to panels that are mounted flushwith flat rooftops. The roofing system is tilted at a five degree angleand is the first all-in-one photovoltaic (PV) rooftop product thatincorporates the solar panel, frame and mounting system into a singleunit.
Arizona Public Service (APS) has already agreed to purchase therenewable energy credits (REC) from the new Goodyear solar power system, which is expected to account for 70 percent of the energy consumed bythe 600,000 square-foot facility and offset 3,500 tons of carbon dioxide emission annually.
This latest installation builds upon a relationship between Macy’sand SunPower that began in 2007. Since then, SunPower has installed more than 12 megawatts (MW) of solar capacity at over 30 Macy’s buildingsthroughout the United States.
