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.

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.

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.

Yes, it is possible to install solar panels on a tar and gravel roof, but it is not the ideal roofing material for a solar installation. The process requires roof penetrations to install the solar racking system. While installers will seal these penetrations, they still increase the risk of leaks. This risk is higher on tar and gravel roofs, which are often flat. Flat roofs are more prone to leaks than sloped roofs because they can pool water during heavy rain and hold snow for longer periods, exposing the roof to more moisture.
