"We had a large solar system installed a year ago by a local solar company. After a year the system melted down due to some faulty wiring. It took a month before the system was functional again, but our battery was also taken out in the melt down. We were told it would take a few weeks to get the paperwork through the system to warranty out our battery. After waiting three months we decided to contact Green Ridge Solar to see if they could help with our problem. To say they were life savers is an understatement. They answered the phone immediately, understood the problem and sent out a very experienced electrician in a very timely manner. They were able to warranty out our existing battery and we decided to order an additional battery through their company. The new battery was only half the cost from the first one that was installed by the original company. They were fast, friendly and professional. I would hire them again in a heart beat."

"Great . First company contacted wanted to replace the Cadet heater even after I replied it may only be the thermostat. Merrill listened to the customer, replaced thermostat and now working fine. Inspected electrical panel, explained why no replacement needed and advised to use my money on upgrades.?"

Solar Panels FAQs, answered by experts

It’s possible that installing solar panels can lead to mold on the roof. The panels themselves are not the issue. Problems caused by improper installation—such as roof leaks and mounts that aren’t sealed properly—can cause mold. Another potential cause of mold is debris accumulation under panels, which can trap moisture. If you live somewhere with extreme snow, rain, or hail, your home could be more prone to mold.

DIY solar panel installations are hard to manage by yourself. You’ll likely need some help or prior experience to make the project worth the effort.

Learn about common solar blockers in your area to determine how often you should wash solar panels and the best cleaning method:

  • Soot: If you have a fireplace, soot can disperse and accumulate on the solar panels.

  • Debris, dirt, and leaves: These natural elements require light cleaning. Being close to trees or living in a desert area can cause more of these to accumulate.

  • Pollen: Areas with a high pollen count require more frequent solar panel cleaning, and sticky plant material requires a deeper cleaning.

  • Bird droppings: Bird droppings are binding and more difficult to remove. Keep this in mind if you live near a lot of surrounding trees. 

Solar shingles typically last between 20 and 30 years, a lifespan comparable to that of traditional solar panels and standard asphalt shingles. The exact duration depends on the manufacturer and the quality of the installation. Because solar shingles are a newer technology, there is limited data on their actual long-term performance. Factors that can impact their durability and longevity include weather conditions, roof ventilation, and regular maintenance. To extend the life of your solar shingles, you should conduct regular inspections and cleaning, and make any necessary repairs as quickly as possible.

There are a few great questions to ask a solar contractor or inspector when you speak to them. You’ll probably want to find out about the energy yield and efficiency of your array, ensuring the actual output matches the amount you calculated when installing the array in the first place. It’s also a good idea to find out about any damage or wear and tear on the array and to inquire about how soon you need to make repairs or replacements to essential components.
