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.

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.

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.

He was extremely knowledgeable about solar and made the process of designing our system straightforward and easy. Because I had travel plans, we couldn't start immediately, but the Syndy team scheduled our installation for Jul 27 - 28. Everything went exactly as planned. The materials arrived on Jul 24, and Martin and his crew, showed up right on time at 7:45 AM on Jul 27. They worked incredibly hard, efficiently completing most of the installation that day and returning the next day to finish the remaining panels and cleanup. That evening, seeing our panels generating solar energy for the first time was an amazing feeling! PG&E installed the Tesla Backup Switch a few days later, and everything seemed to be moving perfectly - until our Livermore city inspection on Aug 7. Unfortunately, we failed because an approved heat detector had not been installed. I was extremely disappointed. It felt like having an amazing present sitting right in front of me but not being able to open it! There were a few additional hiccups, but Jason stepped in, took ownership of the heat detector issues, and worked to get everything resolved. We finally passed inspection and received our permit on Aug 26, followed by PG&E Permission to Operate (PTO) on Aug 28. A huge thank you to the entire Synergy Power team: - Martin, Eliel, Manuel, and Nate for the excellent installation - Rebekah, Melissa, Mark, and Amy for keeping us informed - Jason for stepping in and getting the final issues resolved Overall, we are extremely happy with our solar system and grateful to the entire Synergy Power team for seeing the project through from start to finish. Thank you, Synergy Power, for a job very well done!

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

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.
