We incorporated A1 Sun, Inc. in 2007 with the goal of installing superb, affordable photovoltaic and thermal solar energy systems to benefit our neighbors, our community, and the larger global environment. We are located in Berkeley and work locally in our home town and the surrounding cities of Oakland, Emeryville, Albany, El Cerrito, Richmond and Orinda and beyond. Founding members Larry Giustino and Paul Cooper both have 30+ years of experience in the solar field. Alameda County folks may remember Paul and Larry from the solar installation company Solar Station, Inc. and the nonprofit sister organization AEC - Alternative Energy Collective in the late 70’s and 80’s.
