terrible company

signed contract with company in august 2021 and still waiting to have it installed jan.2022. Lied to me from very start. they would start in sept didn't do anything until i started to complain middle of oct. and blamed it on utility co. they never started anything with utility co until oct and i checkedwith utility co. which had no record of anything from these people.they don't reply to emails or return will regret doing business with this company. save your money. they seem to have only one electrician to do their work.the last people they had here,middle of dec, didn't seem to know what to do. i bought good equipment Panasonic. Panasonic should use better judgement in picking dealers.

Run away! Lies on recordings and emails

Worst business experience I have ever had... Dan Moran lies soamy times, ripped me off, didn't order parts and failed to communicate anything about my project after getting his money and running around calling me a liar. Even the emails in his face and he's disrespecting me on a recorded call and won't stop repeating himself that they don't exist. I never got my rebate for paying in December, I still don't have power because they still haven't set the entire system up because they never ordered the parts, I have been lied to four times about install dates or arrivals and task of the day. The commincatiin is non existent. Once they have screwed you and robbed you, they won't contact you ever again. I even have recorded call of james the owner lying out his rear and promising me this and that. Then never speaking to me again and falling on his stupid face for the promises he made. Disabled veteran with a child and service animals freezing to death with no power for xmas or new years and now they areovkng towards ruining our Valentine's day also. Run as far as you can and don't believe their false promises and remarks. They want your money and that's all.

Excellent solar panel company

I recently had my solar panels installed with South Texas Solar systems They could not have done a more professional job if they tried. I am extremely please with my panels the installation and all the workers but most of all I’m loving my $22 electric bill I got last month.

Great company with the best prices

I had an array installed at my house by this company and most months don't have an electric bill to pay. The price was great and so was and is the service. Highly recommend South Texas Solar to anyone wanting to go solar.
