He has earned our trust by selling and installing 9 panels. So we recently ordered 16 more. He was completing those today and i had an urgent MRI, which required sedation so my wife drove me. We left Jesse in our home as he needed to do some work in the attic. Not only did he do that part of the job, he blew away the chips left by previous roofers. Yes and he cuts no corners. He is finishing up now, putting end caps on the open frame's metals - he wants our roof to look good. If you're interested in some solar or a lot of solar, he's you go-to.

My husband and I wanted to add solar panels to our roof, and we're so glad we went with 512 Solar…read more They were efficient, responsive, and within budget. We did our installation in 2022 and have seen our energy bills lower than ever before! (We have some shade on our roof so we didn't do the full roof, ~20 panels or so, but it worked out well.) They did the rebate work with the city so our out-of-pocket cost wasn't exorbitant at all. Our household also recently purchased a second electric vehicle so we contacted 512 Solar again, this time for a level 2 charger installation. Once again, 512 Solar was excellent at getting our quote together, suggesting two hardwired chargers that the city does rebates on, and actually getting the work done as well. We have to do the final step with submitting the rebate paperwork to the city, I believe, but that's small beans compared to all the work that JP and Huiyun did for us at the outset. Really happy we went with these folks and will continue to recommend their business!

You can tell they're totally in your court, they're insanely efficient at getting you solutions and they genuinely care about doing a great job. It's rare to get a company these days that isn't full of crap, but Cool Roofs is certainly one of the good guys! Looking forward to having them in my address book for a long time!

Wanted to review right away but I waited a couple of months to see if the system performs as expected and I am finally ready to review now. I am an electrical engineer myself and I had done my research so I know when someone is giving me bs on a solar system. I got 10+ quotes from different big and small solar companies. Not only Texas Solar guys had the cheapest quote but they also did not give me any bs. I was a little concerned because they were relatively new in business (although Sean had previously worked with a large local solar provider). However, Sean and the crew did an excellent job. They customized the system according to my requests and installed it in 1.5 days. Had a minor issue after installation and Sean responded promptly to fix. Very satisfied with the whole experience.

I purchased my solar system from Longhorn Solar in April 2022. Unfortunately, my experience after…read morethe installation has been very disappointing. In August 2023, I needed a new roof and paid over $13,000 to have Longhorn Solar remove and reinstall my 37 solar panels. The panels were supposed to be cleaned before being reinstalled, but they were not. They were also reinstalled with the dirty side facing my front porch, which was very noticeable. On top of that, I had to wait approximately four weeks after my roof was completed before the panels were put back on. In May 2025, a connection issue caused my entire system to stop producing power. Because my system uses a single inverter, when one issue occurred, none of the panels worked. It took nearly two months to get the problem resolved, leaving me without solar production during that time. Now, in May 2026, the system has stopped working again. It has been almost three weeks, and I still do not have an appointment scheduled for repairs. It feels like customer service and system maintenance are not a priority once the sale is complete. I purchased 37 panels with the expectation that they would offset approximately 80% of my electric usage. That has never happened. Even when the system is operating, I consistently have electric bills between $180 and $200 per month.
