Diamond Solar Inc.

This company provided a very services at very good price. They always on time and came trew with al the answer to my questions I highly recommend them.

I’ve had the solar system installed on Dec 2021. You can literally watch your meter go backwards and know that you are saving yourself a lot of $$$. Diamond did a fantastic job on installing my system. Diamond's project management team walked me through the installation process. The project coordinator (Tiffany) explained every detail regarding how the system works and how to monitor its productivity. She is great to work with and is very responsive to his customers. I've researched a lot of solar companies, Diamond is by far the best in the industry. I'm going to use Diamond again for my rental properties!!

My experience with Diamond Solar was great! I got my solar installation done with them. I was very impressed with there work. I appreciate how they help maintain my solar panels and make sure to assess my roof for any leaks.

Customer service was excellent. They are very helpful and knowledgeable people. My questions were answered to my satisfaction. All in all it was a pleasure to have their services. I recommend this company to my family and friends 10/10 work

The Diamond Solar team did an excellent job with our installation. From the outset, the quoting was informative and reassuring, not the pushy sales technique we'd encountered from some of the other providers. Diamond's quote wasn't the lowest, but still very competitive and the system was spec'd with premium equipment. No corner cutting here. Overall, we weighed up the cost versus quality, responsiveness, and company reputation to select Diamond as our provider. We weren't disappointed! Tiffany did a great job coordinating our installation around our own contractor taking care of some necessary roof repairs. The team showed up at the time and date promised, and set to work quickly and efficiently. The quality of workmanship was first rate and we had no problems at all with the install. The permit and PG&E sign-off process went well with no effort needed from us - all handled by Tiffany and the team. Our installation exceeds our expectations and easily pays for itself. Again, you will find cheaper companies, and you will find more expensive companies, but Diamond Solar gave us a top-tier system, high level of professionalism, and a great overall experience. Overall, I would highly recommend speaking to them if you're considering a solar installation.

Tiffany, Leo and Adam at Diamond Solar have been an excellent team to partner with on a highly specific solar system design that maximizes production from my roof.

The technical approver (Tiffany) really knows her craft, and also has the credibility and connections within Diamond Solar to make things happen quickly and correctly — even when a project goes well outside of the average equipment for a residential install.

I appreciate that the team helped source equipment that was relatively harder to get (high-wattage solar panels), and also has been open to working with me on creative layouts that almost 50 panels on my flat roof (just under 20kW DC).
