Solar Panels FAQs, answered by experts

As long as your solar panels are properly installed without damage to your roof, they will not shorten the roof’s life span. Solar panels can act as a cover or barrier to your roof and help block external elements, such as debris, heat, and UV rays. Reduced exposure to the weather can extend your roof’s life.

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.

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.

The best way to know if your roof can support solar panels is to hire a structural engineer. They’ll look at your roof and approve the design of your solar panel system or suggest changes. The best roofing for solar panels is made from strong materials like asphalt shingles and metal, but tile and gravel will work. Softer materials like thatch or temporary structures are not a good fit.

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.
