PowerFin Brings SolarHost, First-of-its-Kind, Rooftop Solar Program to San Antonio

CPS Energy selects PowerFin as Provider of Innovative Rooftop Program

PowerFin Partners, a solar development firm based in Austin and San Antonio, today announced SolarHost TM, a groundbreaking pilot program with CPS Energy that will allow participants to host photovoltaic systems on their rooftops in exchange for credits on their energy bill.

Working under a power purchase agreement with CPS Energy, PowerFin will install and operate five megawatts (AC) of rooftop solar on homes and businesses throughout the CPS Energy service territory, offering the community the chance to realize the benefits of local solar at no cost to them. Interested CPS Energy customers can pre-enroll into the program by going to

“SolarHost makes solar available to a much larger cross-section of our community by removing the upfront cost for the customer and in fact creating an income stream for them,” said Cris Eugster, Group Executive Vice President, Chief Generation and Strategy Officer.

“We are excited to provide affordable and reliable on-site electricity to CPS Energy’s customers through this innovative program,” said Jason Pittman, PowerFin’s Vice President of Development. “PowerFin is coordinating with CPS Energy and the local solar installer community to seamlessly integrate this new solar option into the existing grid.”

Through SolarHost TM, qualified residential, commercial, or non-profit electric customers of CPS Energy can apply to have solar systems installed on their rooftop.  Bill credits will be awarded at the rate of $0.03 per kilowatt hour produced by the panels for 20 years.  PowerFin will pay all costs for installation and maintenance.

The innovative program complements CPS Energy and Clean Energy Collective’s  Roofless Community Solar program announced in July.  Together, the programs make participation in solar energy more accessible, affordable, and available to a much broader base of the community than ever before.

Both the Roofless Solar and SolarHost pilot programs will roll out later this year.
