What Customers Are Saying
"I decided to "Go Solar" last summer and called Larry Giustino at A1 Sun, Inc. Careful, efficient, outstanding workmanship - the process was painless."
– Helen Green, I.E.P., Berkeley
"My experience with A1 Sun has been great! Not only was the work done on time, on budget, and exactly as promised, but Larry has gone way out of his way to help with forms, bureaucracy, and new developments. I couldn't recommend this company more enthusiastically."
– Joe and Betsy Schlessinger, Berkeley
