How long do solar panels last?

Most reputable manufacturers offer production warranties for 25 years or more. The average break even point for solar panel energy savings occurs six to 10 years after installation. If the panels continue to produce at a high level for another 15 years after that, you will end up saving thousands of dollars during the solar panels’ lifespan.

Do solar panels stop working after 25 years?

After 25 years, solar panels will be less efficient and produce less power. This doesn’t mean your solar panels will stop working, but they may be less effective at powering your home and lowering your energy savings. When panels degrade to the point where they no longer produce power, they’re ready to be recycled.

How long do solar batteries last?

Solar batteries can last anywhere from 5 to 15 years on average. Lithium-ion, lead-acid, and nickel batteries are some of the most commonly used types of batteries in solar energy systems. Just like solar panels, solar batteries degrade over time.

Do solar panels degrade as they age?

As solar panels age, they begin to degrade; although they may no longer be considered functional, they still produce electricity to some degree. Degradation is a measure of the decrease in output of a solar panel over time. This is not the same as failure, which happens when the solar panel suddenly stops producing electricity.

Do solar panels expire?

There is technically no expiration date on solar panels. However, over time, they naturally tend to become less efficient at producing energy. Some panels can also break due to physical damage from extreme weather conditions.

How often should solar panels be replaced?

One way to keep your solar system operating at its peak is to sync up your roof maintenance with solar panel maintenance and replacement. Depending on roof shingle types, a typical roof needs to be replaced about every 25 years, which is the perfect time to potentially replace your solar panels.
