"Exact Solar and the Bortman’s installed solar panels for me on both a previous house and my current house. The panels turned my poolS from the cold poolS that no one wanted to go in, to the fun warm pools all summer with no marginal cost to heat. They did a free solar study from google earth to determine if my house and pool were good candidates for the panels, answered every question and installed them as advertised on time and on budget."

"Matt from Super Powered Solar arrived within the expected time frame. He took his time and answered all my questions before starting the job. He was able to to get to the solar panels on my two story home and replace the failed micro-inverter under one of the solar panels. He then came inside and helped me get the new micro-inverter activated with the company that supplied this replacement unit. He knew what he was doing and the job was completed to my satisfaction and the new unit is now working normally with the rest of the system."

"Stone Energy diagnosed and replaced a damaged solar panel on our house. Our system was installed years ago by a company that's now out of business, and the first few solar companies we contacted did not want to touch it. Stone Energy responded promptly and positively, and they completed the work quickly and at a very good price."

"I contacted Solar Medix replace two DC string inverters on our 15 year old solar array. As it turned out, they were able to correct some wiring instead of replacing the inverters! Thank you for doing a fantastic job! They saved us a few thousand dollars! And I highly recommend them!"

"The work went well. The exterior faucet had to be replaced but the work had to be done from inside my house on the wall. Sam cut the lower panel, removed the leaking faucet, replaced it with a new faucet and then reapplied the panel and trim perfectly. I was very pleased to see there wasn't any excess damaged done to my interior wall and all looks like nothing had been removed. Job well done!"

"Our AC kept tripping the circuit breaker, so Vaughn came out and told us we needed a new compressor. However, even after installing the new compressor, we kept having the same problem. Vaughn sent two different techs out to troubleshoot and they could not find anything wrong with the unit, so they told us we needed an electrician. We had two different electricians come and neither could find any problems with the circuit breakers, one even replaced the circuit breaker just to be sure. So Vaughn came back a THIRD time and finally found the problem which indeed was electrical. The techs pulled a length of damaged wiring that ran from our unit to the circuit panel that was black and smelly and so badly burned that no insulation was left, just exposed wires. We are so glad they found this enormous hazard that could've started a fire. Throughout the entire experience, everyone I spoke to on the phone was kind and patient and they cleared their schedule for me two days in a row. They show up on time and they stand behind their work. Couldn't be more pleased!

Solar Panels FAQs, answered by experts

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. 

While solar panels can be a great investment, they aren’t ideal for every roof. For example, some roofs, especially older or structurally weak ones, may struggle to support the added weight, leading to potential damage. Roofs with complex designs, obstructions, or limited sunlight exposure might not provide optimal conditions for solar energy production. Consider these downsides when determining if solar panel installation costs are worth it.

Depending on the climate in your area, the best time to install solar panels is either winter or early spring. Summer is a fine time to install panels, too, but it tends to be the busy season, so prices may be higher and companies may have packed schedules. The installation process can take more time than expected between getting permits and finalizing a design, so start as soon as you can.

While you can install solar panels by yourself, it can be a complicated process full of lots of manual labor, risky roof work, and knowledge of electrical wiring. Most solar panel installation projects should be reserved for a trained professional—especially if you plan on connecting your panels to the electrical grid rather than for off-grid use, which doesn’t require utility services.

Homeowners replace their solar panels after 25 years. That said, you don’t necessarily need to replace them at the 25-year mark. You’ll notice a declining ability to produce electricity over time. Most homeowners spring for a replacement when they notice their energy bills creeping up to regular levels or when solar panel repairs are extensive, frequent, and no longer economical.
