How Long Do Solar Panels Last on Average?

There are over 50 billion solar panels installed around the world today, as more and more homes are using solar panels to power their electricity.

But how secure is a solar panel investment? How long do solar panels last before you have to replace them?

If you’re looking to install solar panels, these are some pressing questions. In this article, we’ll be looking at the factors that affect their lifespan while offering tips on how to extend your solar panel’s lifespan.

How Long Do Solar Panels Last?

Figuring out how long solar panels last depends on a few factors. The biggest one is the solar panel degradation rate. Let’s take a look at what that means.

How Fast Do Solar Panels Degrade?

Solar panel degradation rate is the rate at which solar panel output falls every year. A 2012 study by the National Renewable Energy Laboratory found that on average, solar panel output falls about 0.8% every year.

Now that 0.8% isn’t the same across all solar panels. Some brands might build sturdier panels, and technology is improving all the time. This means we might see lower degradation rates each year.

That’s why some have a 0.8% degradation rate, while others might have 0.5% The top brand even go as low as 0.3%!

How fast your solar panels degrade also depends on where you live. The climate can often hamper or extend a panel’s lifespan.

Average Lifespan (and What That Means)

So with all that in mind, solar panels generally last between 25 to 30 years.

That doesn’t mean most solar panels just break down and stop producing electricity after 25 years. It just means that by that time, the energy production is lower than what the manufacturer thinks is an acceptable amount.

As such, solar panels can technically work for decades. Since it’s stationary, the climate and external damage are really the biggest factors
