Occidental Power Solar & Cogen

We're celebrating our 25th anniversary leading the way in solar PV, solar thermal installations and cogeneration systems for San Francisco homeowners, commercial and non-profit. We provide the best American-made solar panels and products with our partners SolarWorld, local companies like solar thermal component manufacturer Heliodyne of Richmond; San Francisco's Tom Lee Roofing, Inc. and Excelsior Roofing Co. We are a California corporation, a licensed California General contractor (B license) and licensed Solar contractor (C-46) CSLB #591549. We've been designing, installing and maintaining solar PV, solar thermal and natural gas cogeneration systems since 1989. Our mission is to sustain good business practices. We also use quality products from local, national and international companies. Every job we do is designed by our professional staff and often meets or exceeds government and industrial codes. Together, our staff has decades of experience working with alternative energy systems. You won't find that anywhere else.
