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!

Upon learning…read moreabout a roof leak and some other areas of wear and tear, I decided to do a full roof replacement with Northstar this year along with a change to my solar array. Again, Ryan was very approachable and accessible. For both jobs, he facilitated an informative teleconference, describing the scope of each job. Project costs are competitively priced. His team is timely and professional. Both jobs were done on time. Minor adjustments or work order changes were easy to navigate. Overall, great experience.

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.

Now he tells me my solar system is gonna cost me around $7000 more. I waited 4 months for this nonsense. I have pics of messages 1to8. Be aware and do your research, if you have ac running , 2 batteries is good for a couple hours only after dark. I have solar and 2 powerwall before so I know. In the daytime the panels are good to power your house and fully charge the 2 powerwall with good sun light. Nighttime powerwall takes over only for a couple hours with my ac set at 78 degree in Modesto ca. when battery is drain I'm back using power from the grid. So I have to pay for solar system and to the electric company. Winter is better but doesn't have good sunlight so Battery doesn't get fully charged. Winter consume less electricity but consume more gas from heater. I try to talk myself out of getting solar but They keep raising electricity or else I wouldn't need solar. Solar and battery degrade over time and warranty only cover if it's broken so down the line when your system is not producing enough power but still working they not fixing it. Thats to what I understand . I guess you're stuck and out of luck. I got nothing against Tim he's a good guy but I'm just upset about how he went back on his words

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.

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.

As a custom home builder in the Bay Area, I regularly coordinate solar installations for new…read moreconstruction homes. Many cities now require solar systems to be installed, inspected, and signed off during rough construction, and fully completed before final inspection approval can be issued. I reached out to High Def Solar for a quote on a new construction project and scheduled a phone consultation. To help streamline the design process, I requested an email address so I could provide all the relevant project information upfront, including: * New electrical panel location and amperage * Appliance load sheets * Roof plans * Exterior elevations * Homeowner energy usage statements * Construction timeline and rough inspection schedule Instead of working collaboratively, the salesperson refused to provide an email address and stated they would only speak directly with the homeowner. Once I explained that I was the builder managing the project, I was told they did not want to discuss the system with "a construction worker" and insisted on dealing only with the client. This made absolutely no sense considering the homeowner has little to no knowledge of the construction schedule, rough inspection requirements, electrical infrastructure, or timing needed to successfully integrate solar into a new build. As the builder, coordinating these systems is literally part of my job. I've already received proposals and had productive conversations with several other solar contractors who understand how new construction projects operate and were happy to work directly with the builder to properly coordinate design, scheduling, and permitting. Unfortunately, my experience with High Def Solar was dismissive, unprofessional, and unnecessarily difficult. If you are a builder, contractor, or anyone managing a new construction project, I would strongly recommend looking elsewhere. Working with professionals who understand construction coordination will save you a tremendous amount of time and frustration.

From the very beginning to the very end, every detail of the installation was thought out in advance so there were no unexpected delays along the way or issues with the inspection!

In my experience, it's relatively easy to get 80% on a job, but achieving that last 20% is as difficult to get to as the first 80% is. Earthwise never dropped the ball and unbelievably... I'd score them at 100%. SO RARE! I built, own and operate a world class recording studio which has been in Marin for 30 years. Believe me...

Got Watts installed two phases of solar panels on my roof, 67 panels in total. The job was massive,…read morethe price was fair, and the follow up service was excellent. There were hardware glitches after installation, but the Got Watts team reliably spotted them - without me realizing there was even an issue - and sent teams out to ensure my equipment worked as promised. Years later I noticed some leaks through my roof where some phase 2 panels were installed. I notified Got Watts and they sent large crews to my home to rectify the issue over several days. This was no small fix. They probably spent vastly more to rectify the leaks than they did to install the panels to begin with. No one likes to have problems with an install. But, it means a lot for a contractor to honor their commitment and spend vast sums to honor their warranty, and their word, to their customer. I've had "good companies" make promises they wouldn't honor once the initial check cleared. Got Watts was true to their word and treated me in a dignified manner that is rare these days. I would unreservedly recommend the good people at their firm. Special thanks to Sam Moore and Daniel Harrold for their excellent service.
