We signed an agreement with Solar Optimum in September 2025. We were assured several times by the…read moresales rep that the solar panels and battery with the advised non-export option would be installed and operating by the end of 2025 in order to qualify for the 30% federal tax credit. However, Solar Optimum did not even start construction until January 2026 and it took until July 2026 to get the approval of PG&E and the solar panels operational due to both foreseeable delays by PG&E and delays in response and follow-up by Solar Optimum. We spoke with the customer service manager about some sort of compensation for the delays (paying PG&E for power for an additional 7 months) and the lost 30% Federal tax credit. After several weeks of waiting, senior management decided not to offer ANY compensation. The delay by Solar Optimum resulted in several thousands of dollars in lost tax credits and PG&E power cost savings. Shortly after notifying us that no adjustment would be made to the amount owed, the company's attorney sent a demand letter threatening litigation if we did not pay the full amount within 10 days. This was an extremely frustrating and disappointing experience. Don't give Solar Optimum your business!

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.

The product is good, the process left us wanting…read more Eric, David, Jose and the crew did an excellent job. My frustration was with the post installation process. 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.

This review is long overdue!!! I had a new roof put on last summer and had to have both my home and…read morepool solar systems dismantled and then reinstalled once the new roof was in place. Sun Marshall Solar Services went above and beyond my expectations....on time, worked in close to 100 degree heat, with unmatched expertise (they discovered 1/3 of my panels hadn't even been connected....by a well known solar company in my area). I even decided to have them install a new solar system for my pool... it has worked beautifully. In today's environment, where good service is hard to find, this company shines above all others. The owner (Marshall) was a delight and went above and beyond to make sure I was well taken care of. If you need solar work, Sun Marshall Solar Services are the best.

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.

My husband and I dug in our heels FOREVER, when it came to getting solar. There were all kinds of…read moresalespeople who came to our home on a monthly basis, and we just never had a real peace about being able to trust what we were being " sold", or told. My parents purchased solar from a HORRIBLE company that sounds a lot like 'SunFun'. After they passed away, and the house was sold...we were STILL making the monthly payments for over a year!!! That SunFun organization REFUSED to transfer the solar to the new homeowner, and eventually stopped taking or acknowledging our calls. It wasn't until we had to threaten the new homeowner with a lawsuit that SunFun finally transferred ownership. Due to this, we could not trust any of these solar companies...that is, until Kevin Bedard came to our home, and explained everything in great detail to my husband and I. He took the time to hear about our concerns, and he showed us how he truly cared. That same week, we spoke to two other families who shared their positive experiences about Ambrose Solar that made us feel that we would be in great hands. We had FINALLY FOUND A PEACE about getting solar on our home; KNOWING we would be in good hands, and we were ALL IN. It's been six months now, and we are beyond pleased with our solar panels, and the two Tesla batteries we have purchased. We are true fans, who have NOTHING but RAVE REVIEWS for this company. If you don't have solar, or if you need to add solar, Kevin Bedard is your man! and Ambrose is your company. Every employee has been amazing and helpful. In a world where customer service has taken a dump, this company has remained a class act. So again...if you are considering solar, call Ambrose, and tell them Albert and Rhonda sent you.
