Great Repair Service

Photon Brothers is fantastic! We had solar panels installed on our home in 2011. In 2022 they quit working. I attempted to work with the original installer, but they would take, on average, a month to respond to phone calls or emails, and finally quit responding at all. I found Photon Brothers in late 2023 and despite the crazy Colorado weather (causing us to reschedule multiple times), and a very heavy workload, they worked with us until our problem was fixed. The in-house team, Jake, Kaitlyn and Tom, were communicative and really worked to make sure we were taken care of. The field people, especially Mark and Mike, were outstanding. They knew their stuff and were able to resolve multiple problems and get our system up and running. Best of all Jake called us, proactively, to go over every item on our bill to make sure we understood the charges and were satisfied. We will only be using Photon Brothers from now on! Highly Recommend!

PHOTON BROTHERS replaced an off-grid system (24 lead-acid batteries with a generator backup; this arrangement was in place for twenty-five years and more than ready for an upgrade). Getting their attention to evaluate the job was the most challenging part of contracting PHOTON BROTHERS; finally Theo, their estimator, arrived on the site and from there the process went well. Conversion from the old system was a labor intensive task (removing 32 solar panels from a steep roof along with 24 lead acid batteries, two inverters, charge controller & wiring infrastructure). Weather was stormy much of the time, creating delays. In spite of uncooperative weather, though, the new Tesla Powerwall system was in place in approximately three months. Since then it has performed flawlessly. Installation staffers were knowledgeable, good communicators and answered all questions. Communicating with Project Manager Katlyyn was always uplifting. She gave a timely and thorough response to any inquiry, always with a happy tagline, and provided flexibility when needed. I recommend PHOTON BROTHERS for an off grid conversion. Their experienced and efficient people know how to expedite the permitting process, complete the work expeditiously, and keep clients up to date as the project evolves.

Excellent Job - Installation to Follow-up Issues

Photon Brothers did an excellent job in the midst of the Covid of getting the proper perm and installation of our solar system with the back up batteries. It was challenging but thanks to their team especially Theo the lead Electrician on the job, as well as some needed follow-up work during the last couple years has been exemplary, we were not charged for any of the follow-up work. They felt it their responsibility to get it right.

Terrible, terrible company and people. They just lie and lie and lie. They ruined our roof installing the panels and refused to pay for the damages because “it was already an old roof” even after telling us our roof was in fine shape for installation. They also refused to remove and reinstall the panels when we did get our roof fixed unless we paid them almost $9000. The cherry on top is that they breached our contract by not installing part of the system and then lied by saying it was impossible to install on our house when in reality it would have just been more work than they wanted to actually do. Currently pursuing legal options. DO NOT use this company

Great experience with Photon Brothers

We had our solar system installed by Photon Bros in 2021 and have enjoyed using the monitoring app to see our production month over month and year over year. Recently we had the misfortune of an inverter issue. When we learned of the loss in system production we emailed Photon Brothers directly. I received an email response from their service department and the individual had included their direct contact information in the signature line of the email. Who does that anymore!!! I was thrilled to have this line of communication, so I immediately picked up the phone. Again, to my surprise, the individual answered. I proceeded to explain what was going on and they said they would check on the work order and get back to me the next day. They did just that and even continued the line of communication for the next week until the issue was resolved. That individual was Katlyyn Arnoldi, out of their CA office. Katlyyn is a huge asset to Photon Bros. as she was very professional, patient with a frustrated customer, presented a positive attitude, gave me the basics and facts and earnestly cared about my experience and system. I told Katlyyn how much I enjoyed working with her and how happy we were with Photon Bros. Photon Brothers, you need to work hard to keep Katlyyn on your front lines, as she is the face of your organization and takes pride in her work, which shows through her interactions. Thank you Photon Brothers for standing behind your product and workmanship. Best regards, Tonya

You should pay in full after ALL work is complete.

I made a mistake when I signed the contract for my panels by agreeing to pay the full price as soon as the panels were finished being installed. I was told several times “Our work is done” and you have to pay us in full. But here’s the problem: their work is not done. At least here in Boulder, CO. Photon needs to pass inspection (with an employee present) and then apply and be accepted into the utility company’s (Xcel) queue for new meters to accommodate the panels. I agree, it is not difficult to do this. My panels we installed in early May and I paid the bill as required by the contract. Several weeks went by before the inspection, which did not pass. Several more weeks went by while the plans were modified and someone came out to the house and made the required changes. Then several more weeks went by before the next inspection, which required a little more work on Photon’s part before fully passing. Another week passed, and then I started calling Xcel to see if I was on the queue. Turns out they did not fill out the application correctly, so another week was wasted. Oh, and then we had a leak in the roof where Photon forgot to put in a screw and our bedroom ceiling was stained and the carpet wet. They did come quickly to fix the leak, the project manager no longer works there, and they did pay one month’s electric bill because of the delays. The system was turned on September 7, 4 months after I paid the bill. I strongly recommend you sign a contract requiring 50% up front, 25% at completion of installation, and 25% when you are in the queue with the electric company and the solar company’s work is actually finished. I paid too early and had no recourse, because they had all my money. And I feel like our project was a low priority for them as soon as the bill was paid
