Longhorn Solar, Inc.

Do not honor warranty

Update: Installer corrected the problem by installing a new inverter, 26 days after reported. I paid a system in full with longhorn solar, the system did not last 1 year, a broken inverter. Longhorn keeps claiming chain supply issues while still getting new businesses, but not repairing mine. Their support system is basically none, one email contact that might or might not reply you in 3 days if you are lucky, and never gives a clear answer. I have a dead system, including a 16kw battery. Lesson learned, Look somewhere else, and force them to put a specific repair time window in your contracts.

Just OK

Our experience was overall fine. We got more information about available rebates than the other company we got a bid from, but the prices were comparable. We had a ground mount system installed and it seems to be working as expected. We did have to call them back for not filling in the trench properly. After a rain, we had a 200' ditch of almost a foot, where human or cattle could be injured. They came back out to fill it...filled half and wanted to be done. I had to point out the other half beyond the fence. They initially were going to install a "Sense" monitor, but said we did not have space on our box so put one on the array that we could not even read from the house. We got a new box and asked for the Sense. It took them weeks, poor communication, and then they installed and left without making sure it was functional. Basically the breakdown seems to be in the coordination/communication department. People would show up to work without notice. They would try to move up work dates without regard to other issues we were coordinating. There were just a number of annoyances that didn't have to exist if they had better management and communication. So while the work seems solid (time will tell), the overall experience was not great. I felt like once we wrote that last check, I could expect the bare minimum.

Came up short

I had my system for a year now. Despite not using more energy than the prior year, I'm still getting an electric bill. My system size was under estimated by at least 2kw. Not pleased that I made a significant investment that wont pay for it self for at least 10 years and still have to deal with electric bills.

Excellent, but then Poor

I recently had a PV system installed by Longhorn Solar. From the beginning, Rex and Paul did an excellent job of advising me of my options and working with the engineers to design the best system for my needs. At that point my experience with Longhorn was simply outstanding, so I chose them over two other companies and signed a contract. After that, there was a long delay while the electric utility and HOA approved the design, etc. That was expected, but even so, it would have been great if somebody at Longhorn would have touched base with me at least once every couple weeks to let me know what was happening on my project. After about a month I inquired, and finally met my project manager. Not long afterward, there was some progress on my project. Eventually the project manager and I set up a time for installation, and I arranged to take that day off of work. The day arrived, but the installers did not. After three hours I contacted the project manager. I learned that the installers were running so late that they would need to reschedule for another day. I wasn't happy about wasting half of a day off, but we rescheduled for the following week. That day also came, and essentially the same thing happened. This time I called after only hour to confirm that people were still coming. I learned that the installers were running behind because of recent rains, so I would have to reschedule again. The installers actually showed up at my house by surprise one day and performed the installation. Later I learned that there had been some supply issue with my panels, and that I had therefore received an upgrade for free. That was great, but I should have been informed before the installation. Finally, Longhorn neglected to set up the monitoring of my system until I reminded them a couple weeks after it was switched on. In the end, I am happy to have an excellent system, but my experience with Longhorn Solar was incredibly mixed. The pre-contract people were extremely professional and responsible. The post-contract people never showed up when they were supposed to, and communication was either missing or misleading. I have no post-contract experience with any other companies, so I don't know if this is unusual. Based on other reviews, it is possible that I was just unlucky, and I drew an inexperienced or overworked project manager.
