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.

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!

I had one good experience with these guys when then installed a tesla charger at my old house and…read moreat terrible experience with them with they installed a tesla charger at my new house. The first time they did it they installed a 240 volt outlet in my garage and I plugged a tesla mobile connector into that, worked well. The next time they did it at the new house, I thought they would do the same thing but apparently they stopped installing the mobile connectors. Now they only install the wall connector which is a large sci-fi looking thing that is permanently affixed to the wall. It's also more expensive than the mobile connector. None of this was made clear to me when we started the project with Grayzer. They came to my house, got about 90% done with the job then saw the equipment I had and said "sorry we don't do those anymore". They explained the situation to me but since I didn't have the equipment they wanted they couldn't finish. They did however insist on being fully paid for the job. Stupidly, I agreed to pay them and they left saying "call us when you have the wall connector". That was a mistake. Never fully pay for the work until the job is fully done! So I bought one and scheduled a time to finish at which point they said they would need to charge another trip fee to come back out. I explained that it wasn't made clear to me that I didn't have the right equipment until the job was almost complete but they didn't care. They were insistent that I give them another trip fee before they would come back. Frankly they were pretty rude about it too. Like really rude. Whoever I was emailing was belligerent and completely unprofessional. It was extremely frustrating. I tried to explain that as the professionals in this situation they should be the ones checking that all the equipment is ready to go before the job starts. At the time I didn't know the difference between a mobile connector and a wall connector. I didn't even know that tesla had multiple options for wall chargers. I had what I used the first time so I figured it would work. It's not that the trip fee was so much money but after having to drag this out over two visits, spend another $150 to upgrade to a wall connector, a trip fee on top of all that was a bit much. In my opinion, a reasonable company would just accept responsibility and waive the second trip fee. Or at least offer to split it. But not these guys. They dug their trench and they weren't coming out. It was childish and stupid and I'm embarrassed for them. And to boot, the people they sent out to finish up the job were jerks. One of them was yelling and cussing at somebody on their phone like a crazy person in my garage. Honestly, these guys are like school on a Sunday -- no class. I guess this is what happens when you get to be a popular company. Customer service and basic decency goes out the window because what do you care, you have plenty of business. Right? Yeah right.

So I was in the process of adding a Tesla Wall Connector to my home. I sent out a request to three…read moredifferent companies ( all Tesla Certified installers ). All were prompt in their responses and provided well written proposals. Only Grayzer included the cost of a permit in their proposal. Further a friend had their wall panel upgraded and their Tesla Wall Connector installed by Grayzier and recommended them highly. After looking at the reviews for the different certified installers, and given that a permit is required in my town to install an EV charger, I went with Grayzer. They provided a date and service window ( a week in advance of my appointment ) and the electrician, Max, pinged me about an hour prior to his arrival. I showed Max my ideal location for the Tesla Wall Connector and he was able to accommodate without having to cut away any drywall or running conduit outside the wall ( YMMV ). Very friendly, professional and knowledgable. He took the information/pictures required by Tesla and by my town's permitting authority, commissioned the Wall Connector, showed my how to add it to the Tesla Application on my iPhone and verified that it was charging at the specified rate (48 amps). He was happy to answer any questions I might have, and I am just delighted by the service and work done. I would recommend highly to friends, neighbors, et al. All in all, quick, fast, efficient, and professional. Cleaned up work area when done. Thank you!

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.
