We had some solar panels installed by Diablo Solar Services a couple years ago and we are very pleased with the high level of customer service that they provided. We found out about them from a flyer we received in the mail and I'm so glad we did. When they came to check things out for the installation they were very thorough, they made sure to describe in detail everything they were going to do. The installation process itself went very well and we had no issues whatsoever. The only thing I wish they would is follow up with us on new solar products because I am very interested.
