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.

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.

Communication was excellent throughout the process. The system was installed in one day by the proficient field staff. The start up and instruction of the solar app that monitors the system was professionally executed by Mark. He explained the entire system and the set up in layman terms. My overall experience with this company was excellent. I would highly recommend them.

Working with him has been one of the best experiences I've had in many years. The solar system has been a great benefit to me, and I really appreciate all of Jamie's help throughout the process.

Thank you, Jamie, for your honesty, hard work, and outstanding service. I wish you continued success for many years to come! Kay

A Team That Actually Cares About Their Work…read more From the start, Solar Harmonics stood out because they treated me like a person, not just another lead. Jamie and his team were responsive, clear about costs, and never pushed anything unnecessary. The installation crew showed up on time, worked cleanly, and left my property spotless. They installed 19 panels with Tesla Powerwall 3s at my home in Antioch, and everything has been running perfectly since day one. The panels look great, the Powerwalls perform flawlessly, and the app setup was smooth. It is rare to find a company this transparent and easy to work with in the solar world, but these guys nailed it. I highly recommend them. Gordon & Jana

These guys are the real deal. Honest, good quality work, they communicate well, and best of all…read more.. they are competitive on pricing. So many solar companies are overpricing there systems. It's common to see AFTER rebate quotes. These guys did an amazing job for about the same price BEFORE rebates. That's right, 30% less than some of these crazy quotes, for the exact same product, REC panels and Enphase. It was a difficult install too given the roof. I have 12 facing west, 5 facing south, and 3 panels facing east. I highly recommend the west facing panels as they produce the energy the most, when you need it the most.

This "company" is run by one, very old guy who takes weeks to reply to emails. He FINALLY finished…read moremy initial installation 4 months late. He uses contractors to do the actual work, and, in my opinion, they are sub-par & sloppy. Mark guarantees your system for 25 years, yet, since it is a one man show, and that one man is quite old, unvaccinated, and VERY unlikely to live another 25 years good luck getting that guarantee honored after he dies. He says his son is taking over the business, but in my dealings with him I have seen zero evidence his son is involved in any way. Even worse, I have had 2 panels/or inverters fail in my system. The first one took Mark months to address! For the second one, I have been asking Mark to honor our contract for 9 months! He refuses to do so and has blocked my email and texts, thus he is again, in breach of contract. Working with this company has been an ongoing nightmare since the first day over 6 years ago. He also marks up the panels and inverters 400% over actual cost. I strongly advise you to avoid this company like the plague, unless terrible communication, LONG project delays, and a meaningless warrantee is what you are looking for. If in spite of all this factual, first hand experience you ask for a bid from Mark, ask him for a simple breakdown of materials and labor. He will refuse. But...if you get one, check the actual online prices for the Enphase inverters and solar panels yourself. You'll see the mark-up I'm talking about. One more thing, I have several leaks in my roof since Mark installed the system over it, and Mark refuses to take any responsibility for that either.

Follow up email from Charlotte Fontanilla stated the Support Team suggested a visit to my residence for further assessment. She stated she would let me know when a service appointment could be finalized. Didn't hear anything and honestly I forgot about it until January. Called again in January and supposedly Charlotte was pretty good at NOT following up with customers according to person I spoke with. Well the response was better this time. They came out and tested "installed modules" and submitted claim on my behalf with Canadian Solar. That claim was denied but after consulting with SolarEdge they identified that it was related to the optimizers rather than the solar panels themselves. Optimizers were replaced and now different panels are not working properly. After back and forth for 4 more months now it's the panels that are bad BUT not bad enough to warranty. Very interesting. I'm hoping someone in the company with integrity will read this and fix the situation. When I purchased my solar from West Coast Solar I was told and I quote "you got bumper to bumper 25 year warranty everything is covered". Well apparently it isn't.

By which I mean the technicians who come out have been awesome, pleasant to deal with, and do good work. When its working as Id like, the system works great. All that to say as long as you never ever ever need to reach out to them for literally anything, you'll have a great experience. Otherwise, its a nightmare. After installation it took 6 - 8 weeks of constant emails and phone calls multiple times per week to get them to resolve the installation issue (circuits missing off the backup loop) and correct my storage profile for charge/discharge. Trying to get their help both times after that has been equally atrocious, and with my system currently down I emailed the, and opened a ticket on their website (where both their phone numbers are non active) and it took another week to get a response. At this point i'd say 2 years feels consistent enough to say 4/5 stars on install and installers, 0/5 stars on customer service.

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.

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.

My mom and I couldn't be happier with the service we were provided from start to finish. We contacted the business in late July of last year to see about installing a solar system on our home before the end of the year. Within in days, Alessandro was here to meet us in person and provided us with a comprehensive breakdown for solar options and pricing. We loved that we were treated like actual people instead of a number in a queue. Given that there was a slight backlog of jobs they had to work through we were assured that we would have our system fully installed and activated before the end of the year, which we did! It was great working with Nick who was our onsite rep and Juan was always available to answer any questions we had by phone (of which I had many). Despite the number of times I called, he was always patient with me and provided detailed answers that gave me a better picture of our installation and how our system would operate moving forward. I can't say enough about how amazing the whole process was. Looking at our electrical bills right now and we're in awe of all of the savings we're getting, which validates our decision to purposefully oversize our system. If and when we decide to install a car charging station in our home we're definitely going back to Sunlight!

I can't say enough good things about Carlos Gomez from Sunlight Electri-Cal Solutions…read more I've been working on a non-standard solar setup using an EcoFlow Delta Pro Ultra X and EcoFlow Smart Home Panel 3, and finding a contractor who truly understood this type of system was incredibly difficult. I spoke with many contractors, and almost all of them sent salespeople who gave generic answers or tried to push cookie-cutter solutions that clearly didn't fit my setup. Carlos was completely different. From the moment he arrived, it was clear he wasn't a salesperson -- he's an engineer, and it shows. He took the time to deeply understand my system, reviewed actual spec sheets on the spot, and immediately identified issues that other contractors completely missed. Multiple companies told me Hyundai panels would work fine. Carlos checked the amperage limits, applied proper safety margin calculations, and clearly explained why those panels would not work with my EcoFlow system -- saving me from a costly mistake. He also walked me through: Proper panel selection within voltage and amperage limits Safe string configurations and series wiring How to maximize roof space while staying within code Permitting requirements I hadn't been told about before On top of that, Carlos identified critical code and safety requirements that no one else mentioned: Bollards required in the garage to protect battery units Correct battery placement to maintain required clearance from doors and entrances Heat detector requirements for battery installations in a garage These are all things that would have caused inspection failures later -- and Carlos caught them immediately. He spent well over an hour with me, climbed onto my roof to check for obstructions, inspected battery placement, reviewed wiring paths, and answered every question in detail without ever rushing me. What truly sealed the deal was how efficient and transparent the pricing process was. Carlos was able to turn around a detailed quote very quickly, and when I received it, I was honestly surprised -- it was a significant amount lower than every other quote I received, even though his evaluation was by far the most thorough. Given everything: His technical expertise The level of detail and care The ability to integrate with my existing system The fast turnaround And the much better pricing Choosing Sunlight Electri-Cal Solutions was a complete no-brainer. Carlos is knowledgeable, meticulous, honest, and genuinely passionate about doing things the right way. After meeting him, I completely understand why this company has such strong Yelp reviews. If you're in the Bay Area and need electrical or solar work done the right way, especially for a non-standard or custom system, I highly recommend Carlos and the team at Sunlight Electri-Cal Solutions.
