Solar PPA gives Foothill Ranch Medical Plaza HOA clean power, lower energy costs, and a new roof solution without an assessment, reserve draw, or upfront check.
FOOTHILL RANCH, CA, UNITED STATES, June 8, 2026 /EINPresswire.com/ -- The Foothill Medical Center Association has energized a 300-kilowatt (kW) rooftop and carport solar system at its commercial property at 26700 Towne Centre Drive, completing a combined solar and roof modernization delivered through a fully-financed power purchase agreement (PPA). The project was financed by Sunrock Distributed Generation, developed by WattHub Renewables, and built by SunRenu Solar. Under the agreement, the Association received both a fully operational solar system and comprehensive roof reconditioning across all solar-supporting individual tenant units with no upfront cost.
The newly-installed system is forecast to generate approximately 506,000 kilowatt-hours (kWh) of clean electricity annually, offsetting around 95% of the center’s Southern California Edison (SCE) load under the GS-2-TOU tariff. This is expected to reduce CO₂ emissions by around 359 metric tons annually, equivalent to removing 78 gasoline-powered passenger vehicles from the road each year.
A Smarter Solar Model for Commercial HOAs: Solar + Roof, No Check Written -
For many commercial HOAs, going solar looks attractive on paper but is complicated in practice. The biggest obstacle is often the roof. 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, re-install the array. Foothill Medical Center Association was able to avoid this issue entirely.
WattHub Renewables structured the project so the economics of the PPA could support both the solar installation and roof reconditioning. SunRenu Solar then executed both scopes together, delivering a coordinated roof-and-solar project designed for long-term performance.
The result is a cleaner, lower-cost energy solution paired with a warrantied roof system, delivered through a single agreement and without requiring the Association to fund the work upfront.
“As a non-profit commercial HOA, every dollar of operating budget matters to our members/owners. This project lowers our electricity costs immediately, protects us from utility rate escalation, and gives us a new roof with warranty – and we did not have to levy an assessment or draw on reserves to do any of it,” comments Ashley Cardo, Real Estate Manager with Pacific Coast Commercial Real Estate, agent for Foothill Medical Center Association.
Chris Leonard, Chief Revenue Officer of WattHub Renewables, comments: “Foothill Medical Center is exactly the kind of property that has historically been left out of the commercial solar market. It is a well-run HOA with a suitable roof for solar that had reached the end of its useful life. By structuring the PPA to cover the roof reconditioning alongside the array, we eliminated the single biggest obstacle to adoption for properties like this one. “Our job at WattHub is to make clean energy work for real buildings with real constraints. The Foothill project is a template we are already applying to other commercial HOAs across Southern California: one agreement, one contractor, one lower monthly bill – and a new roof included.”
John McDonnell, Principal of SunRenu Solar, says: “Executing the roof reconditioning and the solar installation as a single, coordinated scope meant the Association didn’t lose use of its property to back-to-back construction campaigns. Our crews completed both workstreams on a tight timeline and handed back a building envelope and a generation asset that will perform together for decades.”
“This project shows how creative financing can turn a capital challenge into an operating advantage,” says Wilson Chang, CEO of Sunrock Distributed Generation. “Foothill Medical Center Association needed more than a solar array – it needed a roof strategy, energy savings, and budget certainty. By financing both the solar system and roof reconditioning through a single PPA, we helped the Association move forward without an upfront check, special assessment, or reserve draw.”
