Recent reviews frequently mention professional presentations, smooth permitting, and tidy workmanship. Several customers note timely completion and successful integration of batteries and upgraded panels. Communication and guidance through questions appear as recurring positives. There is also at least one critical review about a deposit and refund dispute, reflecting a concern about clarity in cancellation terms.

Thomas Phavong on United Solar Electric

My wife and I had a very concerning experience with United Solar Electric regarding their business ethics 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.

John Hollis on United Solar Electric

We had a great experience with United Solar Electric. They had a professional presentation for a proposed system, and they professionally and timely installed an upgraded electrical panel and 10.5 kw system. They handled all of the permits as you would expect. I would highly recommend them.

Doug Brott on United Solar Electric

I couldn’t be happier with how my solar and battery project turned out. From start to finish, the installation was handled professionally and thoughtfully, even when the system involved some fairly advanced components.

The solar panels, Enphase batteries, IQ System Controller 3M, and meter collar were all installed cleanly and correctly, and everything works exactly as it should. What I appreciated most was the willingness of the team to take the time to get things right, answer questions, and work through details rather than rushing the job. That gave me real confidence in both the equipment and the installation.

Now that the system is fully up and running, it’s been rock solid and performs just as expected. This was a significant investment for me, and it feels great knowing it was done properly. I’m genuinely grateful for the support and follow-through and would absolutely recommend them to anyone considering solar and battery backup.

Paul Cheng on United Solar Electric

I had a great experience getting my solar system from United Solar Electric. From sales to installation and turning on the service, the entire process was executed according to the schedule outlined in the contract. Everything went smoothly. The project was scheduled to be completed in three months and was finished two weeks early. It's working without a hitch.

Shoutout to some people I worked with the most at USE:
Sales: Angel Ortiz
Angel was a great guy to work with. He was patient in helping me understand how solar works and what competing options were available. He helped me find the right size solar system for my needs. His pricing was also competitive. Most importantly, I really appreciated that there was one go-to person that I could get all my questions answered before I buy.

Project Manager: Anahi Ortiz
Anahi managed my installation. She communicated with me regularly to keep me updated on our progress. Everything went smoothly and on time, from the evaluation, installation, inspection, permits, touch-ups, to the final turn-on. Every target date was met on time, and there was never a moment when I felt lost or unable to find someone to help.

Evaluation/Installation Team and Inspection/Turn-on
The installation looks good. I didn't see any visible damage to my house. The installation team installed the equipment as I had instructed. For example: (1) they kept the electric conduits away from the skylights to avoid future skylight maintenance that could damage the solar system if they were too close, (2) they installed the batteries on two wall studs instead of one for stronger support, and (3) they made the conduits more aesthetically pleasing by using more straight lines with minimal steps.

Areas of Improvement:
The battery outer shell cases had multiple scratches along the edges and on the front side. They were probably laid on the concrete ground and dragged or kicked while the main batteries were installed or during inspection. While the product is outside the house and I won't notice the cosmetic blemishes, I still wish that they could look impeccable, especially considering the cost.

Gus Cicala on United Solar Electric

United Solar completed a rooftop solar installation for me and I am very happy with their work. I had a ton of questions and they were able to help guide me through the process. I completed a roof replacement right before the solar, so I was a little nervous about the penetrations. However, my roofing company sent someone to inspect the solar install and they said it was one of the cleanest solar installs they have seen.

I would definitely recommend United Solar and Electric for your solar project!
