You would think if we're paying $50,000, they would make sure everything is installed properly! We tried calling and calling them. When our panels were installed, they didn't give us what we wanted. We wanted to be off grid, and to connect our old panels to our new panels. This didn't work out. We were also promised a $15,000 rebate check by Jonathan and Nate. Jonathan told us it would take two weeks. Nate said it would take 4. Now, we're a couple months in and we haven't seen anything. I leave voicemails for the office and I get no reply. I really wish I would've gone with a bigger company with more experience. I feel somethings off here.

The Freedom Forever guys cut my water line TWICE while installing the panels. Then they sent me an amendment stating my monthly bill would now be more than twice the cost the sales guy told me.

I didn't sign anything after the amendment and did not turn the system on. When I called Freedom Forever they said the system had been turned on and was running. These ppl are so shady and the sales ppl they use are garbage. They'll screw you and then say "well you signed". Very expensive lesson learned. Do NOT do business with this company.

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!

We unfortunately had our solar installed by a company that went out of business and completely stopped returning our calls and emails, regardless of our warranty status. Enphase referred us to Lighthouse Solar to try to resolve our issue. Not only did they resolve our issue, they did it quickly. I cannot attest to how their pricing compares to others, but their workmanship and professionalism are worth it, even if someone else could offer the service for less. So thankful we were referred to Lighthouse Solar. They have found a lifelong customer in us. HIGHLY RECOMMEND!

Solar review. TLDR;…read moreWorking with Blake and his team was super simple and very personal feeling. Always in direct contact via texting and emails. Would recommend. ATX SOLAR came around our neighborhood door-to-door where the houses were just being built with only a handful finished. If you've ever been in that situation, there are LOT of people that knock on your door daily. Blake's team was very different, and the only ones that got our business. They were laid back, not pushy and just had facts about solar along with some nice small talk. Should also note they were the only people that had a business card. We set the appointment and a few days later Blake himself came to give me more info on solar and the whole unique process he takes. You could tell that Blake goes about business differently compared to the rest of the solar industry where scams are frequent. Integrity, upfront facts about panels and their output and clear communication along with setting reasonable expectations in regards to solar was how I was sold on solar, not the feeling of being pushed. We opted for the REC Alpha Black series panels and their 25year warranty. Blake and his team kept us informed via text, and email through the whole process. He was always answering questions we had via text, regardless of business hours. It was a breath of fresh air to deal with a small family company, and the superior customer service. Blake and his family have also stopped by numerous times to make sure everything had been going well and to make sure the install was completed to his high standards. I would highly recommend ATX solar again and again.

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.
