  I was almost run off the road by one of their drivers. I recommend nobody trust their employees to deliver quality service.

  Just had a white utility truck driving all over the road. Tailgating me and other vehicles on highway 12 going towards I 5. What type of people do you hire? And then When I took a picture of the vehicle that has your name and your phone number all over it He crossed over a solid line to pass all the traffic. Like he was running away from something. Does your company hire sketchy morons?

  They do exactly what they say they'll do, at the exact time they say they'll do it. Quality installers, quality electrician, Corrine is a gem!

  We chose Calsolar based on their outstanding response to my initial calls and questions. Don was very responsive and listened to my questions and concerns.

• It posts on Facebook. A page that stopped posting years ago tells you something a listing will not.

Google’s own “people also viewed” set, in Google’s order. It is Google’s comparison, not ours.

Ordered by how much we can tell you about each, which is not an order of quality. We do not know which of these is better and would not say if we did.

• —The date above is the newest review we hold, which is not necessarily the newest that exists — we hold a large share of Google's reviews, not all of them.
• —We do not verify licences, insurance or bonding. Nothing here has been checked against a state licensing board.
• —We cannot tell you what an installation costs, and we hold nothing about the equipment they fit.
