"Per my contract with Redrocks Roof and Solar, I am to notify them if I suspect my solar system is not producing per their design, and to begin an "underproduction claim". If underproducing, they will compensate for lost production. My system operational as of May 5, 2025, I contacted them in August 2025 informing them of above stated concern. Called 3 times without a response until finally tech came out with last second notice on 9/2/2025. Fortunately I was home, helped him find 9 out of 14 panels that were never wired in. Photos were taken/sent to Redrocks. Additionally, it was discovered a setting on the system phone app given to me to monitor system was not enabled, which they were supposed to explain in detail to me and never did. So for 4 months my system was only producing 33%, Brooke (owner) acknowledged in a live phone call on the spot. I never received parts warranty details per the contract, no response after emails and phone messages about all this. I DO NOT RECOMMEND!!!"

The install crew was extremely professional, always on time, quick and did a great job. The monitoring software is medium. I was also sold on the 110vac 20amp outlet that ties directly into the inverter. This is a very handy feature."

"Mario, the technician, seemed very nice and knowledgeable The $49 quoted trip charge turned into a $220 diagnostic charge not including any service. He wasn’t sure why water was appearing on the floor, but felt it may be due to some clogging of a PVC drain tube. He said it was not possible to simply clean it out, but it should be replaced at a cost of another $250 (for a pipe?). We declined. We subsequently had another repairman come in who said there is no problem cleaning the tube and did so. The material clogging the pipe is shown in the photo."

"Paul could not fix the furnace because he didnt know what was wrong with it!

Oh, but he did charge her for this! The problem was a tripped power supply breaker. None of the listed components needed replacing. Paul is a CROOK!"

Plumbing problems are never convenient and can be quite costly and stressful. The last thing you need is for a company to give you the run around. When you contact Benjamin Franklin Plumbing®, we will promptly send one of our qualified, professional and friendly plumbers to your home to take care of your problem as quickly as possible. Each of our plumbers must undergo months and even years of rigorous training before they are sent on an installation or repair job on their own. Whether you are looking to maintain or repair your plumbing system or install a new toilet, faucet or hot water heater, our services have been created to fit your needs. We look forward to working with you!

"This company sent out a tech to our home. He took a look at the water heater and saw the pilot light was out. He did not do any troubleshooting whatsoever, only proceeded to say we needed a new water heater. He gave us a quote which included many warranties we did not want so we declined the quote and only paid for the service call. I asked the tech if he could at least light the pilot for us he said he could not for safety reasons. We had another company install which did not do any troubleshooting either. Turns out the gas meter outside was clogged and that is why our old heater was not working. They should have did some troubleshooting but did not do so to make an obscene amount of money. We were screwed by both companies. Our utility company changed out the gas meter and started our new water heater. Companies need to do troubleshooting and actually care about people and not just about making a quick buck."

FAQs for solar panel installation projects in Longmont, CO

Annual inspections are recommended for residential solar systems, though specific needs vary based on several factors. Newer installations in moderate climates require less frequent professional evaluation, while systems over a decade old or those in harsh environments benefit from more regular attention. Always arrange an inspection following severe weather events that might have damaged components or affected system performance.

Pre-inspection cleaning isn't necessary, as evaluating the current condition of your panels is part of the assessment process. Professional inspectors can effectively examine systems regardless of cleanliness level, as accumulation patterns often provide valuable diagnostic information. However, if panels are completely obscured by heavy debris, bird droppings, or other materials that prevent visual examination of the surface, a basic rinse might be helpful before the scheduled inspection.

A comprehensive solar inspection examines all system components, including panels, wiring, mounting hardware, and inverters. Technicians check for physical damage like cracks or delamination, evaluate electrical connections for corrosion or looseness, and assess overall system performance against expected output levels. The inspection may also verify that safety systems are functioning correctly and that the installation complies with applicable codes and standards.

While traditional manual inspections are effective for most residential systems, specialized inspection methods may provide advantages for certain installations. Factors to consider include system size, roof complexity, accessibility challenges, and safety considerations. For multi-story homes or commercial installations where roof access is difficult or potentially hazardous, alternative inspection approaches offer improved documentation and reduced risk, though potentially at a higher cost.
