"I selected Home Energy Center based on Angie's List ratings and their coupon for a free diagnostic service call. Steve Cupps was fantastic. He arrived at our home on time and quickly diagnosed two problems. Although he had another service call to make at 5:00 pm, he returned at 7:30 with the required parts (three in all-two from his warehouse and one from an auto parts store) and finished the job. Since the weather was in the 90's every day, we were extremely grateful for his willingness to provide same day, after-hours service. They honored the Angie's List coupon and allowed us to avoid the costly bill of replacing our furnace and AC."

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.

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.

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.

The best way to save money on solar panels is to take advantage of federal and state solar incentives. For example, the solar investment tax credit (ITC) offered by the federal government can save 30% of your total—if you can take the entire credit, which is based on income taxes owed—or an average of around $9,000. You can check the Database of State Incentives for Renewables and Efficiency (DSIRE) for state and local incentives that could save you even more.

Professionals use the same methods to install solar shingles that they do for asphalt shingles, so you’ll often see a similar installation timeline of one to two days. The amount of time required will depend on the size and slope of your roof and the number of shingles installed. Weather conditions can delay installation, as working on a roof is unsafe during high winds or heavy rain.
