Robert C. came to my home and went over the advantages of adding a few more panels that would still keep me in tier 1 status with the power company as well as consideration of adding a Powerwall III battery. Considering the increased power generating capacity of newer panels and storage capability of the Tesla battery, I was sold by the quality and value of the expanded system. The design and contract review was done online in a timely fashion and it was a swift transition to installation taking place in just one day, as the the lead installer (Antonio) was joined with two co-workers who explained how the project would move forward and answered all my questions. The work was complete by 3pm and I was extremely satisfied with the entire process. Thank you Semper Solaris for a quality job for a fellow veteran. Dan

I recommend Sunlight Electrical Solutions…read more My home solar/battery system was having intermittent issues. The company that installed my solar had gone out of business. The owner of that business recommended Sunlight Electrical to fix my system. I spoke with Carlos at Sunlight. He sent out Isaac who seemed very capable. Isaac's assessment was that my system had multiple wiring issues and recommended a service that would require a larger team to complete. He explained why, and I concurred with Isaac's recommendation. Carlos scheduled a larger team to come out the next week. They were led by Jesus, who also seemed quite knowledgeable. Jesus and his team worked diligently for 4 hours. They found more wiring errors as Isaac has predicted. And they found a damaged Tesla MC2 unit on the roof which had cracked. After they completed their repairs, the system started operating better than it ever had before. I estimate that I am now getting an extra 10-15% more power from the solar panels. In addition to providing capable technicians, I really appreciate that Sunlight is so easy to work with. I asked several highly technical questions and always got thoughtful answers. If you want something done a specific way, just ask them. They have such a positive, customer oriented attitude that makes them a pleasure to deal with.

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 want to start by saying I don't understand all the negative comments. People with solar systems…read morethat are years old and complaining about Tru Up bills.. the prices from PGE have gone up dramatically over past few years and you need to still use energy conservation once panels are installed. Lastly, financing anything comes with additional costs. A great way to avoid the finance charges is pay cash or get your own loan under terms that fit your financial needs. It is my understanding that 1st Light Energy does NOT finance solar systems but outsources that for customers who need/want to go that route. After considering these three facts let's move on to my review. Garrett was my point of contact person and he was upfront about the costs versus my savings. He called a month prior to my appointment for installation because he had a cancellation and I was able to get them installed the same day! Any questions I have had he is a email away and has been friendly, honest, and helpful. Fast forward three years I have now installed panels again on my second home. Same great company and customer service. Same situation where the company had a cancellation and I was able to get my panels installed sooner than expected. A year from my second installed panels has past. I never had done a review and realized it was time to do so! Fun fact, this is a small local business that the owner and his brother (co-owner? Idk ) both work at. I highly recommend this company!

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.
