Alter Systems

Alter Systems specializes in custom designed residential roof mounted, ground mounted, and pole mounted PV systems using only the best equipment at the best prices. Whether it’s a grid tie, a hybrid, or an off grid system we have over 25+ years of combined experience working on solar projects across California.  Alter Systems has the ability, the know-how and the experience to offer our customers a broad range of solar solutions. When it’s too expensive to run a utility line or you just want some backup power when the lights go out, Alter Systems provides off-grid solar solutions that are reliable and ideal for your home, cabin, ranch or farm. If you have an existing grid tie system and would like to integrate backup power, Alter Systems can re-configure your existing system to create a hybrid design that spins the meter backwards and provides back up power when the lights go out. Call us today and speak with an associate who specializes in off grid applications. We have helped homeowners, businesses and government agencies with hundreds of projects. We’d be happy to show you what we have done in the past and what we can do for you in the future. Click here for more information.Alter Systems serves the greater San Francisco Bay Area with office locations in Sebastopol, CA  and now Oakland, CA.  Counties served include:
