I have had the system installed by 1 Solar for about a year or so now. It is a new system. This summer, my system wasn't functioning right. I looked into and found that the microconverter wasn't working. I contacted Emphase who supplied the materials. They sent it immediately and explained that the business that installed my solar system would need to change it. I contacted Valor Solar, not sure how they work with 1Solar but both have emailed me to let me know their business is too busy to respond to my situation. I contact them on July 15th. It is now over a month (August 17th) and I have not been contacted to set up a date by a technician to come address the matter. They have explained that they have been very busy this summer which I understand. However, I am paying a lot of money for this system. It is unacceptable and poor business that that do not have a process to ensure current customers are taken care of in a reasonable amount of time. Not to mention, I asked if I could change it out myself, no response! Though I believe I should not be the one to fix it. I was told by a representative that it would take 2-3 weeks before someone could come out to take care of it. My system is not working correctly and I find it incredibly discouraging that I am about to go on week 5 and still no effort to set a date to repair it. With all that being said, I do not recommend utilizing either Valor or 1 Solar. Hopefully, there is an effort to address this matter soon.

Had a good experience overall. There was communication throughout the whole process. Ben let me know ahead of time that Xcel and the city can sometimes be slow with approvals, and reassured me that if I didn’t hear from him, it meant things were moving along smoothly. To my surprise, the system was installed in about 45 days and it looks great.

I haven’t received the annual excess energy payment from my energy company. The energy company is starting that the solar panels were not connected (Solar1 is responsible for this). Solar1 texted me recently and I explained the issue. No response for Solar1. I’m suck with solar panels that I can’t receive excess energy payment on. Please help. Solar1/energy not trusted companies! Kenzie doesn’t respond to the issue (text screenshot attachment).

The 1Solar folks have always been very helpful with explaining the details regarding my solar system's performance. And I appreciated Eric's honesty during my recent system review when he said that there really would be no advantage to adding extra panels to my roof when all of the appropriate factors are considered.

Eric Schrader from 1Solar created a nice simple report to help me understand how efficient my solar system was. He was super kind, helpful, and honest in his analysis and recommendation, which I'm very grateful for. Highly recommend! Thanks so much, Eric!

We deeply regret ending up with a solar panel system installed and serviced by 1Solar, because everything about the experience has been time-consuming, frustrating, and incredibly disappointing. From the beginning, the system has never performed as sold and promised. It took over a month of repeated follow-up before 1Solar proposed any kind of resolution. When they finally addressed the issue, 1Solar admitted to making a mistake during the original estimation and design process—but their team also openly stated that the company doesn't want to pay to fix it. They later began citing a lower threshold for guaranteed production that was never mentioned during the sales process. Even by that newly introduced limit, the system still continues to underperform. Worse, 1Solar’s customer service has been unresponsive, difficult to work with, and at times dismissive and bullying. It has taken nearly two months of back-and-forth to get even minimal clarity, and during that time, the company has refused to take accountability or offer any meaningful remedy for the financial harm caused by their design errors—even though we are still under warranty. I strongly caution anyone considering 1Solar—our experience has shown the risks aren’t worth it. Also be aware that they sell systems through third-party vendors. You may not get what you paid for—and should be prepared to deal with a company that operates in bad faith to avoid taking responsibility when problems arise.

I’ve had nothing but problems with 1Solar on my solar addition project. We’ve had over five failed inspections, all due to poor planning and lack of communication on their part. As a result, my solar array has been inactive for months, costing me money every single day it sits unused. The process has been frustrating, with no sense of urgency or accountability from the company. I do not recommend 1Solar to anyone looking for a reliable or professional solar installation experience.
