The system, manufactured and installed by SunPower Corp., is expected to generate the equivalent of 51 percent of the electricity demand at the airport's rental car center, two parking garages and its toll plaza.
"With this SunPower system, Sky Harbor Airport is reinforcing its commitment to energy conservation and improving air quality in Arizona, while saving airport funds," said Phoenix Mayor Greg Stanton. "Councilman Bill Gates has been championing this effort at the city and it's exciting to see it come to fruition."
Rick Whisman, SunPower's Director of Western Project Sales, said the company's technology, "will ensure that the system delivers energy over the long term, reducing operational expenses significantly with no upfront expenditure."
The project was facilitated in part by Arizona Public Service Company's (APS) Renewable Energy Incentive Program, which offers financial incentives to customers that help to offset up to 40 percent of the costs of installing solar energy.
The airport has a solar services agreement with SunPower, which designed and built the system, and is operating and maintaining it.
The airport is hosting the system and buying electricity at rates that are competitive with retail electricity, providing a hedge against rising electricity costs with no capital investment. The renewable energy credits (RECs) associated with the energy produced by the system will be transferred to APS in fulfillment of the state's renewable energy standard and tariff.
At the airport, SunPower installed SunPower E20 solar panels, the most efficient solar panels on the market today, at three rooftop locations: the Rental Car Center and two buildings that comprise the East Economy Garages. System construction was completed in two months at the end of 2011.
