How Long Do Solar Panels Last?

Solar Panels

Solar panels last a lot longer than most people think and have a significant return on investment.

A lot of technology seems disposable these days. Your phone lasts a few years before you chuck it, you’re lucky to get a full four years of college out of a laptop, and there seems to be a new TV to replace the one you’ve got every year. It’s no wonder then that some homeowners are concerned that solar panels will suffer from the same longevity issue. The good news is, solar panels are in it for the long haul. Let’s take a look.

Simplicity Wins

Solar panels are actually, in a way, somewhat simple pieces of tech. There aren’t any digital processors, motherboards, flywheels, pumps, or fans. As a result, this means that there are very few moving parts that can break our wear out. It also means that solar panels typically require little-to-no maintenance. The components a panel does have include a glass-protected solar cell, which is often made of silicon. This simple design allows for solar panels to outlast other kinds of modern tech.

Longevity Matters

Today’s solar panels have improved in some ways: they’re lightweight, produce more energy, and look a lot more sleek and stylish. However, older solar panels have been running for over 30 years. Not to mention the fact that as technology has improved, these panels will last even longer. That’s why we guarantee our panels–both parts and labor–for 25 years. This is also a linear power warranty, as opposed to a standard power warranty, which plots a linear curve of power loss over 25 years so you know exactly what to expect out of your system.

Efficient Panels

We’re not trying to claim that your panels will last forever. After 20, 25, or potentially 30 years go by, your solar panels will start to lose out on some of that efficiency in noticeable ways. It’s been shown that annually, solar panels’ performance goes down by about half a percent. This is due to exposure to water vapor and temperature fluctuations. Still, that’s a much better investment than most pieces of equipment out there and you can be sure that you’re still getting a solid return on investment in the coming years.
