Electric utility Salt River Project (SRP) and SunPower Corp. have completed a 1 MW solar photovoltaic power plant at Arizona State University's (ASU) Polytechnic campus in Mesa, Ariz.

SRP is buying the entire output of the solar plant from SunPower under a long-term purchase-power agreement. The facility is the first commercial deployment of the SunPower C7 Tracker technology, a solar photovoltaic tracking system that concentrates the sun's power seven times. The tracker combines single-axis tracking technology with rows of parabolic mirrors, reflecting light onto SunPower Maxeon solar cells, which have a conversion efficiency of 22.8%.

SunPower engineered and constructed the plant on the southeast corner of the ASU Polytechnic campus, and is currently operating and maintaining it. The plant is expected to produce an amount of energy equal to that needed to serve about 225 SRP customers' homes and requires minimal water use.
