Nicolas in sales was very responsive and easy to work with - answered pretty much all questions we had. Lorena from project management provided timely updates. When it came to actual scheduling and installation Adam & team were right on the money. From signing the contract to permit to installation it took about 3 weeks. Another week for inspection & then PTO was quick too. Installation crew arrived before scheduled time, installed in few hours, and cleaned up everything. Eduardo was spot on with final inspection - the city inspector told me that this was the first inspection that passed on first attempt. So kudos for doing great job without any corrections. Adam was just a phone call away with any questions and he updated regularly during the entire process. They provide tier 1 panels, are certified Tesla installer and provide great price. Their labor warranties are great too. Highly recommended if you're looking for local installer in the Bay Area.

He was extremely knowledgeable about solar and made the process of designing our system straightforward and easy. Because I had travel plans, we couldn't start immediately, but the Syndy team scheduled our installation for Jul 27 - 28. Everything went exactly as planned. The materials arrived on Jul 24, and Martin and his crew, showed up right on time at 7:45 AM on Jul 27. They worked incredibly hard, efficiently completing most of the installation that day and returning the next day to finish the remaining panels and cleanup. That evening, seeing our panels generating solar energy for the first time was an amazing feeling! PG&E installed the Tesla Backup Switch a few days later, and everything seemed to be moving perfectly - until our Livermore city inspection on Aug 7. Unfortunately, we failed because an approved heat detector had not been installed. I was extremely disappointed. It felt like having an amazing present sitting right in front of me but not being able to open it! There were a few additional hiccups, but Jason stepped in, took ownership of the heat detector issues, and worked to get everything resolved. We finally passed inspection and received our permit on Aug 26, followed by PG&E Permission to Operate (PTO) on Aug 28. A huge thank you to the entire Synergy Power team: - Martin, Eliel, Manuel, and Nate for the excellent installation - Rebekah, Melissa, Mark, and Amy for keeping us informed - Jason for stepping in and getting the final issues resolved Overall, we are extremely happy with our solar system and grateful to the entire Synergy Power team for seeing the project through from start to finish. Thank you, Synergy Power, for a job very well done!

Having East Bay Power Systems design install and certify a rooftop solar panel system has been a…read morewonderful experience. Working with the team (Darlene, Jeff, David etc.) to get the system designed and installed was very easy, they took care of everything, including getting the city to approve the design/installation for PG&E. Installation was a simple one day process, and best of all, we were essentially off the grid the next day. Interestingly East Bay Power Systems use American made solar panels (Aptos) and an American made power backup system (Tesla). Not only does the system perform flawlessly, because of there high output of the Aptos solar panels (up to 450W per panel) the whole array of 10 panels is virtually unseen. As an added bonus, they set up a Tesla app on your phone so you can see at a glance how mush power the system is generating, how much is being used to power the house, how much is used to charge the backup system and how much power is being sold to PG&E. For a system this good, overall cost was relatively low, far less than what I was quoted 5 years ago by two different companies. You may have noticed all my reviews to date on Yelp have been 5 star, this is deliberate. Life is too short to focus on that which does not make us happy. This is why I restrict my reviews to those things/places/services that make me happy and appreciate life. Sure, I have been to some really dreadful shops, hotels and restaurants etc., but, like I said, life is too short to spend time thinking and writing about them.

I got answers from Darlene that did not make sense. Sometimes her computer was down other times her phone was down. Sometimes she would call to give me a message only to realize that she had called the wrong customer. Did not enjoy working with her. Finally, Kara engaged and we got the Permission to Operate about two months after the install. Supposedly Jeff (the Business Owner) is no longer with the company and has gone back East, so not sure who is leading their future efforts. For future customers: hang on to a portion of the payment till the Permission to Operate is received not just the installation.

Then he explained the process to me with patience, knowledge and an understanding of my situation. We settled on a date for roof inspection. My roof is difficult to access and they had to come back several times with different ladders but they never gave up and the weren't ever not confident that it could be done easy. Finally the right tools were located. The team was very professional. The install went very well and caused no damage to the roof or my house. The service afterwards has also been great. This is a great value with no cost upfront. PG&E is naturally trying to claw back some sort of a pay increase but so far has been honest at true up. They just increase the price for gas. 5 stars. I recommend them

My experience with Collin was frustrating and confusing. I initially spoke with him about…read moredisconnecting and reinstalling solar panels for an upcoming roofing/expansion project. After learning about the expansion, he strongly encouraged me to meet Benny, a general contractor, because he said Benny was very competitive. I was already in the process of selecting contractors for the expansion but had not signed a contract, so I agreed to let Benny inspect the project and show me how competitive his proposal would be. However, I did not agree that Benny would receive the expansion project, and my main reason for the introduction was still the solar-panel work. I specifically told Collin that Benny did not appear interested in doing only the solar project. Collin assured me that the solar work would have nothing to do with whether Benny received the roofing or expansion work. Based on that assurance, I continued the process and asked Benny to prepare a contract for only the solar portion. When Benny stopped responding, I asked Collin whether I should find another solar contractor. Collin responded, "We can do it," and agreed to contact Benny about preparing the contract. Benny later informed me that the solar price had actually been offered with the expectation that his company would receive the entire addition project. Since I wanted only the solar work, Benny declined the job. I forwarded Benny's response to Collin. Collin apologized for the confusion and said he would call Benny the following day to sort it out, but I never received another update. The main problem was that I specifically asked whether the solar proposal was tied to the larger expansion project and was assured that it was not. I relied on that assurance and lost valuable time. Clear disclosure of the condition from the beginning--and a final follow-up after promising to resolve the issue--would have prevented this experience.

The project was delayed because they required upgrading my main electrical panel from 100A to 200A, and PG&E process took too long. I eventually had to cancel the contract. This year EnergySage referred me to Next Solar, and I'm so glad they did! Their price was excellent: $24,600 for 18 solar panels and one Tesla battery, and they designed the system without requiring a main panel upgrade. The entire process was simple, smooth and fast. Installation was completed in just 6 weeks, and the final city inspection and permit were finished 2 weeks later. From start to finished, everything was done in only 8 weeks.

PG&E was very slow with providing PTO (permission To Operate). We did not receive PTO until end of May 2026, over 6 months from the date when system was operational. PG&E will need to upgrade transformer (December ???) before we can send greater that 2000 watts back to the system. Right now, we have conditional permission to operate, limiting output to PG&E to 2.2 KW.

We were interested in solar for our 1940s home and provided a deposit in good faith. However, after further inspection of our roof and the overall project viability, we decided not to move forward. When we requested our deposit back--before any equipment was ordered or installation began--the company initially refused, claiming it was 'passed' the point of a refund. It was a high-pressure situation where we felt they were trying to lock us into a contract we weren't comfortable with. While we did eventually receive our deposit back after pushing the issue, the initial refusal to return funds for work not performed was a major red flag. Homeowners should be very careful with the fine print here. If you are looking for a company that values transparency and customer comfort over just 'closing the deal,' I would suggest looking elsewhere. We're glad we didn't get stuck with them and are instead putting that money into improvements that actually fit our home.
