"Ian and his crew were excellent! Very knowledgeable and professional. He told me more about my solar system than the company that installed it! They arrived and went right to work removing my solar panels, and once the needed work was done on my roof they came right back and reinstalled them! I would highly recommend them to anyone needing work with their solar system!"

"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!"

Solar Panels questions, answered by experts

In almost every case, solar panels need to be removed to replace roof shingles. In some cases, such as solar installations where the panels are on raised platforms above the roof surface, installers may be able to install new shingles without removing the solar installation. However, to get a quality roofing installation, panels need to come off. Most roofing contractors won’t remove or reinstall solar panels as part of a roofing project, so you’ll need to contact your solar provider.

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.

The average homeowner needs around 22 solar panels, but the exact number depends on your monthly energy consumption. Your solar professional should size your array to offset your consumption, meaning you’ll need fewer panels if you use below-average amounts of electricity, or more than 22 if you use above-average amounts of electricity. The number of panels also depends on the output of each panel. The average is around 400 watts, but you might need more panels if you install less capable equipment. Since there are so many variables, you should have a professional size your system.

No, you cannot turn on a new solar system before inspection. The inspector checks that the system is correctly connected to the grid and that safety components and features are in place. This process prevents problems on the electrical grid and offers protection against fire in your home. 

Your local utility company may also require inspection documentation before you can connect to the grid. An inspection can ensure solar power efficiency and determine how you might increase it.

Yes, installing solar panels or a solar roof can increase your home's value by approximately 4% to 6%. For a home with a median value of $429,000, this could translate to an increase of around $17,000. A well-maintained solar installation appeals to environmentally-conscious buyers and those looking to lower their utility bills, often helping homes sell faster and at a premium in areas with high electricity rates. However, the exact increase in value depends on factors like the local real estate market, energy costs, and available solar incentives. It's also important that the system is correctly installed and maintained; an older or poorly maintained system may not add significant value, particularly if it's near the end of its lifespan. Other solar features, like panels on a shed, can also boost your home's value.
