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. He always took the time to answer my questions and made everything easy to understand. If I ever buy another house, Jamie is the first person I will call for my solar needs. 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

Well all was pretty good until May of 2025. 2 panels were putting out about 35% less than the…read moreothers. I called and was told they would get in touch with SolarEdge Support Team. 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 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.

I was promised to be put on the installation calendar month after month. Employee was rude to my mother. Our system went offline because they didn't install something correctly. We were not informed and received a huge bill. Del Sol did re-imburse us for 1 month's bill. Was promised by the owner he would look at our system for issues, then didn't show up as scheduled. I recently had a leak in my pool solar system. I called the office to schedule a service call. Once again, I was told someone would return the call and get me on the calendar. It's been 7 weeks and no return call. Go figure! I would NOT recommend!

Our Story: We got our panels installed in Nov 2022. We got…read morequotes from two other companies and looked online to a solar energy brokerage for more quotes. We got a recommendation for Del Sol from one of our friends that was happy with their process and service. We reached out to Elvin and he was able to send us over a proposal very quickly based on whatever tool they used to see our roof. He provided two options for our roof, a 19 panel configuration and a 21 panel configuration. We decided to go with the 21 panel configuration for our roof and it estimated putting us at 98% of total output. After looking at the cost of the system, we didn't think we would be able to get it for a couple of years, but Del Sol offers multiple financing options. We decided to use the local credit union for financing. After we decided on the configuration and got the financing locked down, the turnaround time was approximately three weeks. Which was a whole lot faster than we would have anticipated. Installation took a total of two days with the city inspector coming out the second day. After the installation, paperwork has to be submitted to PG&E to be turned on, which took about 10 more days. Bird proofing for our panels was part of the package and it was done a few days after the final install. Our Conclusion: So we've had our panels for about four months and are extremely happy with them. The process went extremely fast. Supporting local reputable companies are very important to the wife and I, for us it definitely felt like the process was very streamlined to the point of being overwhelming. Using reputable local companies for our home improvements has definitely paid off in spades. Del Sol already installed panels in our neighborhood and knew exactly what our HOA required. The permits were pulled in a timely manner, and inspection was scheduled and concluded on the final day of the install. The major hiccup we had was we wanted to get our roof. Inspected prior to the install. The installation team was very professional, and courteous to us during the install and checked in with us every day with what to expect for that day. The final solar manual was delivered by Elvin and he went over everything in it, which also included the app used to track the performance of your system. Everything was laid out and explained as far as all the warranty information and what to do when the county sent you that "home-improvement" letter. I shared our whole story for people that are just looking into getting solar and wanted to know what they might expect. If you're a Brentwood local, and you decide to go with Del Sol, you won't be disappointed. The quote was very comparable to all the others we received. Elvin's service and knowledge was outstanding and the installers were professional and efficient. Also being able to use a local credit Union for financing was an additional plus for us. Yes, I would recommend them for your solar system needs.

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.

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.

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.

It took them weeks and they had never installed these devices before, and ran into numerous problems that required assistance from one guy who appeared to know what he was doing. They do not appear to be working properly. For instance our Ford EV trips the entire system and the system has to be booted back up. The power sold back is so low we are looking at a higher PG&E true up's than when we had no Power Walls. Synergy pointed the finger at Tesla, who said everything appears to be OK, but it really is not working and my PG&E bills show that. Synergy has taken no responsibility to help us diagnose what is happening and maybe it is because they have their money now so why bother with me? Without going into all the back and forth and very little help from Synergy, I will say that they simply stopped returning my phone calls or emails and are offering no more customer service in any way. These systems were put in 6 months ago and yet we know people with NO battery backup systems that pay nothing in true up's, so I ask myself why I wasted $25,000...unless this company does not know anything about the Model 3's and they were installed incorrectly. My only recourse now is to bring in a competent 3rd party company at my expense to look at the system. So the best I can say about Synergy is "buyer beware" and you have been warned.
