Most solar panels come with a warranty of 25 –30 years, though they can continue working for longer. Our guide explains the factors that impact solar panels’ life span and provides tips for helping them last longer. Below is a list of some of the most well reviewed solar providers, who can all provide long lasting solar systems.
What affects a solar panel's lifespan?
Even less dramatic conditions, like high humidity or temperature fluctuations, can affect the panels’ performance and structural integrity. A panel’s lifespan isn’t just about how long it can produce electricity; it’s also about ensuring that it can be recycled at the end of its life.

You can expect to replace your inverter every 10-15 years. Because the racking system is drilled into the roof to hold the panels, it is more exposed to the elements, including sun, rain, snow, and extreme temperatures.
What happens to solar panels 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 well do solar panels perform over time?
Solar panels do not perform poorly over time. According to NREL’s findings, solar panels have an average degradation rate of 0.5% per year. This means that after five years of operation, your power generation will be 2.5% lower than the initial output.
