I received a call from that number today and after questioning the guy for a long time, set up an appointment for next week. He said a follow up call would come in from Chris, his supervisor. When Chris called, I told him I knew it was from A1 Solar Power and NOT PG&E and told him I wasn't interested. I told him to cancel my appointment. He was very nice and said OK. So now I will see if someone still shows up on Tuesday. I won't give them the time of day. Thank you for this site. It was very helpful.
