Diablo Solar has been maintaining my pool solar for a couple years and have always done a great job. I called them for an estimate for solar for my house. Dino was very helpful and responsive. The estimate he provided was extremely competitive, and I look forward to Diablo Solar installing my new system. Excellent experience!

After a year of issues and a lien on our property of $2,500 that the owner Bryan Raymond stated he would pay, I would not recommend this company. We had an unorganized and quick install in 2019 where our roof was compromised many times. Diablo Solar called in their roofer who subsequently put a lien on our property. I guess it's time for Small Claims Court...

This company did our solar installation in the last 6 months. They were always timely, efficient, very communicative throughout the process, and reasonably priced (and not the lowest). We had to call them back in order to fix a broken tile on the roof that was leaking. A roofing company said it likely will take weeks to get the solar company back but they were dead wrong. Diablo was here within 2 hours of calling them, readily admitted the problem was likely caused during the installation and proceeded to fix the problem. If you are thinking of getting solar, I can't imagine a better

The experience with Diablo Solar Services was excellent from the beginning. They responded quickly. From initial contact to designing custom solar system was approximately 1 week. Design Supervisor Dino Calaguas listened to me and didn't try to push equipment on me, but gave me quotes for what I requested. I found many Companies would trash equipment that they did not sell. He gave me different quotes as I requested and each time his quote was adding more value for the system. After revising 5 different quotes in 5 days, it was time to sign the contract and my family was convinced Diablo

Diablo Solar replaced the twelve 8ft Fafco panel system that they had originally installed in 1987 with a new 12x 8 ft Sunsaver system. They did an outstanding job. Our original system performed well but had to be removed and replaced when we had a new roof installed. The removal and replacement were done by the roofer who claimed experience, but the result was not good and I called Diablo Solar twice to fix the problems. The first time was to re-plumb the system (necessary because the new roof was higher). The second time was to re-install the system. This was only partially successful because

We have been Diablo Solar customers for the last several years. This year we had a leak in our solar system and it took weeks for them to come investigate it (I understand, not enough employees, COVID, etc, etc.). When someone did look at it, they never even looked at the system on the roof, they immediately told us the whole system had to be replaced. It took them months to come out to give us a bid. When they finally did, they wanted to shrink our system and told us it was because of existing drainage on the roof. Our previous system (installed by someone else) was installed on a racking system
