Get matched with top solar panel pros in Berkeley, CA

"We had a 19 panel solar system installed at our home in Oakley by United Solar. They were very responsive and got the job done quickly! We will be back for any expansions or upgrades in the future."

"Hiring them is a great way to support your local businesses. They were professional and weâ  re very happy with our solar system so glad we hired them!"

"I recently had the pleasure of working with Ken at Ellison Electrical on a service panel upgrade for my electrical vehicle and completely rewired my new kitchen. Ken was incredibly patient, explaining every step of the process. He immediately understood the floor plan and installed everything to code. His attention to detail and knowledge was exceptional. The quality of his work is evident in every connection and fixture. The service panel upgrade was seamless, my kitchen looks amazing and now my home feels more secure and efficient. He was always punctual, respectful of my property. I highly recommend Ellison Electrical for any electrical project."

"After having a nightmare working with two smaller companies, I decided to go to NRG Clean Power for my solar needs. I?m understating when I say the experience was like night and day: efficiency, communication, and progress the whole way forward. Before I knew it, my installation was complete and my solar equipment was operational. I want to thank Miles in particular for his hard work and constantly being available to answer my questions. Everyone does their job right at this company. Wonderful experience and I?m saving money while helping the environment!"

"Jeff was great to work with. He took the extra time to discuss questions we had while making sure our solar project was managed seamlessly from start to finish. Everything was planned for and taken care of, down to the small details where his crew took the time to color match the new electrical conduit on the roof as well as on the exterior wall of the house. The entire process was completed in a timely matter, from the initial planning stages, through permits, installation and inspections."

"I had a wonderful experience with Solar Sesame. My salesperson Emanuel was professional, courteous and truly awesome to work with... Thank you guys so much..."

"I have to have my roof replaced of the 3 companies that came out Spartan was the only one who addressed the leak I was concerned about. The other companies were going to charge me a bunch of money and let it still leak. They were not going to address it until it was an issue and tell me it was not covered. Spartan was top notch start to finish. The guys working on the house were awesome as well as every one I worked with. I would highly recommend them."

"Appointment was scheduled between 8am-4pm. Waited all day for the tech (Jeremiah) to arrive. Then received a phone call a little after 3pm indicating they needed to reschedule for the next day almost at the last moment. Needless to say, we got off to a rocky start, but Jeremiah did finally show up around 5pm, isolated the problem in less then 5 minutes, showed me what to do and what not to do when changing batteries out of the thermostat, and pointed out which fuse had blown keeping the furnace from coming on. In conclusion, they made this right, I received a well-needed lesson on minor furnace maintenance, and was able to get the furnace working again. Would I hire this company again? Absolutely, and if you are having problems with your furnace, you might want to consider these people as well!"

"Our landscaping in Menlo Park needed a complete refresh. The team replaced thirsty plants with drought-tolerant options that still provide plenty of color and curb appeal. We're using much less water without sacrificing appearance."
