If you need work on your solar panels on your roof ask for Luis Orona, he did a great job inspecting my panels and made sure everything was secure! Thanks for helping me after hours Luis, I’ll be back next season where we could look at upgrading. I appreciate your attention to details, and helping me out!

We had a new home built in 2021. We are 100% off-grid, so we rely solely on our solar for all our electrical needs. We had always been on the grid in the past. We feel we were not given any instruction/education on our solar system from the original contractor –perhaps the intent was to keep us in the dark so we would stay dependent on him. So, we learned as we went. After struggling with the original solar contractor for two and a half years, my builder called Prometheus who contacted us. We are in the Chino Valley area, so it is over 1 ½ hours to our home from Flagstaff. Ryan Holtz, the owner, came to survey our system. He solved a surging problem we were having which the original contractor wouldn’t or couldn’t fix. Ryan patiently educated us and answered questions to which we couldn’t get answers from the original contractor. He didn’t hesitate and assured us he would take care of us and the system. Ryan installed surge protectors on both sides of the inverter, to add to its protection and to safeguard our home electrical. Watching Ryan work, we noticed him slightly shaking his head, as an expert will do when looking at substandard work. As Ryan made recommendations, it became painfully obvious the original contractor had taken many shortcuts when installing our system. Ryan, with my permission, was given remote access to our inverter so Prometheus could monitor our system from Flagstaff. A couple of weeks later, Ryan sent Louis and Christian to our home. Lightning arrestors were installed on the solar field to help protect the charge controller circuits in the inverter. A larger box was put on the solar field for the wiring which should have been done originally. The original electrical box (standard duplex) barely contained the wiring. Larger sized wiring nuts were used instead of ones barely big enough. Inside, an electrical distribution box was added, so all the cabling to the three batteries were the same length, which the manufacturer of the batteries insisted upon for their warranty. A heavier cable was run from that box to the inverter. And the wires were red and black for positive and negative, not all black! An LED indicator light was replaced in one of the batteries that hadn’t worked in over a year which the original contractor claimed they couldn’t obtain. Overall, Louis and Christian got rid of two “rats nests” of wires. Now our wiring looks expertly installed, instead of a haphazard mess. Louis even cleaned the dust off the tops of the batteries, indicating, to me that he took pride in his work! Shortly after Louis and Christian left our home, I noticed a warning light on our generator indicating the battery on the generator wasn’t being charged. After quickly trying to diagnose it myself as it was getting close to 5pm, I called Prometheus. Ryan sent them back and solved the problem, staying on the phone with them. Outstanding! We are very happy with Ryan and his team. We now have peace of mind and a new confidence in our solar system.
