How long do solar panels really last?

Solar as an Alternative Energy Source
2022-10-15

How long home solar panels last is a question that inevitably pops up. To put your mind at ease, solar panels can last anywhere between 25 to 30 years — or sometimes more.

However, this does not mean the panels on your roof will stop producing electricity after a couple of decades. It just means their energy production will decrease by what solar panel manufacturers consider optimal to meet the average Nigeria family’s energy needs.

Solar energy system degradation rates vary depending on the brand, as well as the climate where they are installed. The good news is, modern solar systems are outperforming all expectations.

According to an analysis by the National Renewable Energy Laboratory (NREL), some premium panel manufacturers offer degradation rates as low as 0.3% per year; Meaning, even if you get a standard solar panel 25-year warranty period at 0.5% degradation, your solar panels should continue operating at around 88% of their original capacity after this time.

Do Solar Panels Require Maintenance?

Modern solar panels are incredibly reliable, yet, they do require proper caring and cleaning to stay in top shape to guarantee you receive the most significant solar savings possible during the next 20 to 30 years. So if your solar panels don’t experience any physical damage by high winds, debris, or other factors — you can rest easy knowing they’ll last you decades.
