SunPower Corp. says it has completed four solar power systems totaling 3.8 MW at public water agencies and water treatment facilities in California. The systems are expected to significantly reduce electricity costs at each site, relieving strained public budgets, the company says.
Two of the SunPower systems serve the Rancho California Water District (RCWD) in Riverside County. One of the RCWD installations is a 1.1 MW system at the Senga Doherty Pump Station. It uses the SunPower T0 Tracker, a ground-mounted tracking system. A 612 kW solar parking canopy system was also completed at the RCWD's headquarters.
The purchase of the RCWD systems was financed using low-interest Qualified Energy Conservation Bonds available as a result of the federal American Recovery and Reinvestment Act of 2009.
The other two recently completed systems include a 1 MW installation for Castaic Lake Water Agency's Rio Vista Water Treatment Plant in Santa Clarita and a 983 kW system for the City of Galt's Wastewater Treatment Plant. Both use the SunPower T0 Tracker and were financed through solar power purchase agreements with SunPower. PNC Energy Capital LLC purchased the systems.
