Mr. Gayler educated us on the various solar panel systems and custom designed a plan for our home. The crew showed up during construction hours, and cleaned up their mess on a daily basIs. Mr. Gayler kept us informed through the entire process and was on the job site frequently making sure that all went well. Going solar can be a daunting and expensive project but Mr. Gayler made it a breeze. If you are looking for a trustworthy and dependable construction company that offers white glove service and great value for your solar needs, I recommend giving Greg Gayler Construction a call.

I have recommended HomePro Solutions to a few friends and neighbors and they had a similar positive experience with their installation.

We can't say enough great things about our experience with our solar installation from Northstar…read moreSolar in Danville. From start to finish, we were so comfortable with every individual we interacted with. Our salesman, Patrick was no pressure, extremely helpful and very responsive. Danielle in the office was a joy and our project manager Jason was there for us all along the way. The install crew was phenomenal and completed the entire project in two days. We absolutely love having battery backup especially from 4 to 9 PM when PG&E charges the highest peak rate in the Continental U.S. California has the second-highest electricity rates in the U.S., (only behind Hawaii) which makes receiving power from the sun especially rewarding. If you are considering solar power, we highly recommend giving Northstar Solar an opportunity.

Wow, I cannot say enough good things about Ryan and his team! I hired them to remove our 69 solar…read morepanels and reinstall them after a re-roofing of our home. It's a nerve wracking process but Ryan gave me reassurance things would go well. Upon Ryan's recommendation, we also decided to replace the solar panel racking system installed by Sunrun because we were plagued with roof leaks due to improper sealing of their footings. Ryan and the Northstar team were absolute champs at removing and reinstalling the new system for us. Everyone we dealt with was so professional, kind and easy going. The work was beautifully done and based on all the photos and detail provided by Ryan I am confident we will be safe from leaks going forward. He also had to coordinate the reinstall with our roofer and everyone handled it so well. I 100% recommend Northstar and the team for this task, and also wouldn't hesitate to hire them for roofing based on their strong work ethic and product with our solar project. The price was fair and in line with other quotes I'd received. A couple of questions unrelated to this particular job have come up and Ryan has gone above and beyond to help me out by providing his professional input. So happy with these guys. Thank you!

My wife and I purchased a new 19 panel solar system and Tesla Powerwall in mid 2025. The install…read morewas completed in October 2025. The crew and all of the people at United solar Electric were very responsive and professional. I would, and will do business with them again, (adding an additional battery). PG&E was a problem. 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. To United Solar Electric's credit, they were with us the entire time dealing with PG&E and were just as irate with PG&E as we were. Thank you, United Solar Electric!

My wife and I had a very concerning experience with United Solar Electric regarding their business…read moreethics and refund policies. 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.

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.
