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.

Installing solar panels is worth it if you’re frustrated with paying high utility bills, live in a sunny location, and qualify for tax credits and incentives. Most homeowners cut between $650 and $1,500 from their utility bills each year by installing solar panels. Over the course of your panel’s warranty, you could save anywhere from $16,300 to $37,500, though those in sunny areas with high energy costs could save more than $100,000.

There are a few great questions to ask a solar contractor or inspector when you speak to them. You’ll probably want to find out about the energy yield and efficiency of your array, ensuring the actual output matches the amount you calculated when installing the array in the first place. It’s also a good idea to find out about any damage or wear and tear on the array and to inquire about how soon you need to make repairs or replacements to essential components.

Solar water heating systems are not one-size-fits-all. You'll likely work with a team of experts to get the job done—including solar panel installers, plumbers, and water heater installers.
