SunPower has signed an agreement to design and construct solar power systems totaling 1.7MW at two Rancho California Water District (RCWD) facilities in the US.

Under the agreement, SunPower will build a 1.1MW SunPower T0 Tracker system at the district’s Senga Doherty Pump Station in Murrieta.

The company will also construct a 610kW solar parking canopy structure, providing both shade in the parking lot and solar electric power for RCWD’s facility in Temecula.

The solar systems are expected to save the district nearly $8.5m in electricity costs over the next 25 years.

The state of California, through qualified energy conservation bonds, will provide funding for two solar systems.

RCWD will own the renewable energy credits associated with the solar power systems.

SunPower will begin construction on the two solar systems which will be complete by the end of the year.
