A few months ago, I completed my own rooftop solar energy project. Since I worked as an application engineer for a number of large electric-utility vendors (most notably Siemens and Landis & Gyr), I was familiar with the proposal process, including the stage where the buyer (me) prequalifies the potential bidders. Because of this I ended up with a reputable vendor for my project, and all went as planned.
Recently, I found three other resources for potential residential solar energy clients in an article from PV Magazine. I drilled though Reference 1 to the three federal agencies mentioned therein, and found some useful information. Below I will devote a section to each agency, with a summary and a link to their resources. At the end of this article, I added a fourth section on a California Agency, since I’m from this state. And suspect some readers will also call California home.
