"Adrian was very professional and bent over backwards to make sure that I understood the entire methodology of monitoring my 15 solar panels. I have needed this help for years. I would trust him for installation of solar panels as well."

"Rep. checked entire system. He found several wires not connected properly and fixed this. He also made recommendations regarding the attachment of the panels to the rood that would provide more stability and leakproofing. The representative appeared to know what he was doing - much better than others, including the representative who was engaged by the roofer (who replaced our rood due to hail damage) to disconnect/connect the panels."

Solar Panels FAQs, answered by experts

If you’re deciding between a solar battery versus a generator for the best backup power solution, you can take a few factors into consideration. Solar batteries are quiet while generators can be quite loud. Generators have a lower up-front cost, but they require fuel and ongoing maintenance while solar batteries are more expensive but don’t have many ongoing costs.

While you can minimally overshoot the number of solar panels you need for your home, it's not smart to go too far. Not only is the extra cost unnecessary, but your state may put caps on how much energy your home can produce and send back to the grid. It is always best to work with a solar energy professional to determine the best system size for you.

Ideally, you want to place them facing true south. This is different from what a compass shows, which is called the magnetic south. You can find true south by using an online calculator as long as you know the longitude and latitude of your property. Solar panel placement is key to maximizing the energy you generate, so this is an important step.

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.

In most states, solar installers need to be licensed and insured as solar professionals, although some states don’t have specific requirements for installers. You can use our state licensing tool to check if an installer you’re considering hiring holds the proper licensing. No matter where you live, a member of your solar panel installation company must be a certified electrician to connect your panels to your home and the electric grid.
