What I like about Diablo Solar Services is the fact that they are a local owned business versus being a big national chain and they have been around for a long time and they can also do both solar options that I needed.
I used them only once and if they offered the solution that Tesla is working on or if I needed more panels I would call them back.
I don't need them anymore but I was happy with what they did and if they had other services related to solar technology that I could gain they would probably be the company that I would call.
