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.

You can install solar panels on a flat or pitched roof, but keep in mind that they will need to rest at a 30- to 50-degree tilt for optimal sun absorption. It costs more to install solar panels on a flat roof because you will need to install a framing system and likely hire a structural engineer. If your roof has a pitch of more than 40 degrees, it may not be a good candidate for solar panels.

Insurance companies aren’t against solar panels, but they may have concerns about the risks and costs of insuring solar. The type of policy, where you live, and the insurance company itself matter. Extreme weather can damage solar panels, and faulty installation or electrical malfunctions pose a fire risk—this, in turn, can increase insurance company liability and payouts. However, you’re likely to keep coverage as long as you have a pro install the solar system, keep it maintained, can pass a solar panel inspection, and update your homeowners policy to include solar.

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.
