The Foothill Medical Center Association in Foothill Ranch, California, recently energized a 300 kW rooftop and carport solar system at its commercial property, completing a combined solar and roof modernization delivered with a fully financed power purchase agreement. 

The newly installed system is forecast to generate approximately 506,000 kWh of clean electricity annually, offsetting a substantial portion of the center’s Southern California Edison load under the GS-2-TOU tariff. This is expected to reduce carbon dioxide emissions by around 359 metric tons annually, equivalent to removing 78 gasoline-powered passenger vehicles from the road each year.

For many commercial owners associations, going solar looks attractive on paper but is complicated in practice. The roof is often the biggest obstacle. Installing a solar array designed to operate for 25 years on a roof nearing the end of its service life forces an expensive sequence: Strip the array, replace the roof, and re-install the array. Foothill Medical Center Association was able to avoid this issue. 

The project was financed by Sunrock Distributed Generation, developed by WattHub Renewables and built by SunRenu Solar. Under the agreement, the association received a fully operational solar system and comprehensive roof reconditioning across all solar-supporting buildings with no upfront cost. 

WattHub Renewables structured the project so the economics of the power purchase agreement could support the solar installation and roof reconditioning. SunRenu Solar executed the scopes simultaneously, delivering a coordinated roof-and-solar project designed for long-term performance. The result is a cleaner, lower-cost energy solution paired with a roof system under warranty, delivered without requiring the association to fund the work upfront.
