Installing a solar panel system is a major investment, which is why you’ll want to know how long it’ll last. The good news is that solar panel life expectancy is great and only getting better thanks to advancements in technology, meaning you’ll be able to harness the many benefits of green energy for years after the installation! 

If you’re interested in learning more, let’s take a look at solar panel lifespans, maintenance, and how to take good care of them.

How Long Do Solar Panels Last?

Modern solar technology has significantly improved solar panel longevity, allowing solar systems to be a reliable source of energy for years to come! Most solar panels are designed to last for several decades, with most having a life expectancy of 25 to 30 years. 

Solar panel manufacturers usually provide solar panel warranties that cover solar energy production for up to 25 years. However, solar panels can still generate electricity beyond this period, albeit at a slightly lower efficiency. 

The solar panel degradation rate, which measures how quickly solar panels degrade over time, is relatively low — around 0.5% to 1% annually. By installing high-quality panels correctly and taking good care of them, you can ensure they last for as long as possible!

Do Solar Panels Need Lots of Maintenance?

Even though solar panels might seem really delicate and complex, they don’t actually need much maintenance! While it’s still a good idea to keep an eye on your panels, there are a few key reasons why they don’t need nearly as much maintenance as one might expect.

No Moving Parts, No Wear

One of the main reasons why solar panels need minimal maintenance is that they have no moving parts. This absence of mechanical components means no friction or wear that could otherwise cause breakdowns, allowing each solar panel’s lifespan to extend across decades without the need for regular repairs. 

Slanted Design

The slanted design of most solar panels not only optimizes energy absorption from sunlight but also helps with maintenance. This design helps rainwater naturally wash away dust, debris, and other particles that might accumulate on the panels’ surfaces, which lowers the need for frequent cleaning. A clean surface ensures that the solar panels’ quality and efficiency remain high so that you can enjoy the benefits of a solar panel system with minimal effort.

Want to Help Your Panels Last a Long Time? Monitor Its Performance!

While solar panels require little maintenance, regularly monitoring their performance can extend their lifespan. This is because checking energy production levels and comparing them to the expected output allows you to detect any issues early on. 

Cleaning solar panels can help clear away any accumulated dust or debris and will restore solar energy production to normal. If you live in areas with high dust or pollen levels, where panels are more prone to debris build-up, you should be a bit more cautious.

All you need to do to clean your dusty panels is spray them with a hose carefully, and their slanted design will help the water flow right off. By taking these proactive steps, you can maximize your solar panel system’s longevity and continue enjoying the benefits of reduced energy bills for years!
