South Texas Solar Systems

South Texas Solar Systems works as electricians based in San Antonio, Texas, where they handle solar power installations for homes and businesses across the region. Their focus stays on fitting panels from makers like Panasonic and Mission Solar along with inverters from SMA, Enphase, and SolarEdge plus battery options including Tesla units. Homeowners in the area often call on them for residential setups that aim to lower monthly power bills while commercial clients seek systems for offices, schools, and farms. They also take on ground-mounted arrays and solar carports when properties allow for those configurations rather than roof work alone.

Electricians from the company arrive to complete full installs that include wiring the new equipment into existing home or business electrical systems, and they offer annual panel cleaning as part of ongoing maintenance contracts. Specific jobs have ranged from quick multi-day residential placements where crews set dozens of panels at once to larger commercial projects that require careful integration with backup batteries. Technicians have been noted for moving fast once on site during busy seasons, yet follow-up calls for warranty repairs on items like recalled Tesla Powerwalls or non-working arrays have sometimes stretched into months with delays reported by owners. Ground mounts and maintenance visits form regular parts of their schedule in the San Antonio heat where dust buildup can cut output over time.

Customers have pointed to solid initial workmanship during the actual electrical and panel connections, with one engineer homeowner watching every step of a 2019 residential job and calling the results professional from start to finish. Praise often centers on the speed of the core installation phase and the quality of the physical setup itself, though communication after the crews leave drops off for many and price complaints arise when extra service fees appear for warranty items. Speed and quality during active work earn the higher marks while post-install support pulls the overall average down. DIRT Score 3.28 from 145 reviews on Finds.

“Had them install solar on my house in 2020 and 2021, they have never cleaned or serviced them. The Telsa 2 powerwall was shutdown due to recall by Telsa and they wanted to charge me to replace under warranty/recall the powerwall2 . I having to contact a legit solar company to do the recall. There not even Telsa certified and phone number don't work but yet goodleap was able to get a hold of them. Sound fishy??”

“Don't use them!!! They don't honor their warranty! My system doesn't work and since several months they are telling us that we are on the waiting list! They didn't reply to complaints with the BBB.”

“We signed up at the end of 2018...a busy time as everyone wanted a tax break. They got off to slow start installing in January 2019. First day a few panels...next day the entire system. As an Electrical Engineer, I was observing every point of the installation. Very professional JOB! There Master Electrician made several trip after reviewing the installation photos. Mainly issues with decals. The system is working at or above my expectations, generating more power than it was rated at one point. The system is saving us money in two ways. We are making more power than we are using even with a 5 ton AC. Second, is a real added benefit. By covering up nearly all of my south facing roof, we have essentially shaded the hottest part of our roof. With the ac set at 76 daytime and 71 nighttime, it is late afternoon before the AC cycles. We have had no issues with this Company, but I got the impression they would work with me to resolve any issue.”

“South Texas Solar is great to work with while you’re spending tens of thousands of dollars to purchase and have solar panels installed. Once installed it’s a very different story. We purchased our panels from South Texas Solar a little more than 2 years ago. In their contract they provide 2 free cleanings per year…good luck getting them out that!! Our gateway stopped responding in February this year. I contacted Enphase and they quickly sent us a replacement gateway but it needs to be installed. I contacted South Texas Solar and they scheduled me a few weeks out. I took the day off to be home and they never showed up. I called the next day and they said “oh yes we only had 3 people scheduled in your area and 2 canceled”. Ok so you just don’t show up? No home call??? Bad business! So they rescheduled me for the following week, today! I had them add my brother to their list in my area because in 5 years they’ve only cleaned his panels once. Thinking to myself, that gives them 2 people right there. So they had 4 people scheduled and my brother on stand by in case they had a cancellation. It is now 6pm and see if you can guess what happened? Yep…no call no show again!! The customer service with South Texas Solar is terrible. If I could give zero stars I would. I’ve contacted Enphase back and they’ve sent an email to South Texas Solar. My guess is they no longer care about the customers who aren’t spending new money with them. Absolutely horrible!!”

“DO NOT do any business with this company. My Tesla batteries stopped working since September and they ordered replacement batteries and they haven’t been delivered. I called them many times to try to get them to deliver them and install them, but now their office numbers have been disconnected and I can only reach one of his technicians that has told me he James the owner hasn’t responded to his texts. This is very unprofessional of the owner. I wish I knew how unprofessional James way, so that I could’ve done with another company.”
