How Many Years Do Solar Panels Generate Energy?

While searching for the perfect solar provider for your solar needs, you may be wondering how long solar panels actually last. With such a big investment, it is important to make sure that your solar panels will withstand the test of time.

Luckily, there are studies that have shown that solar panels can last between 30 to 40 years. This doesn’t necessarily mean that solar panels will abruptly stop working after a few decades. Instead, it means that their energy production will slowly decrease so that they no longer fully meet the Average American family’s energy needs. The modern technology of solar panels is proving to outlast and outperform any previous models.

ION Solar uses only top-tier, premium equipment to ensure your solar panels will last as long as possible. According to an analysis by National Renewable Energy Laboratory, premium panel manufacturers offer degradation rates ranging from 0.3% to 0.8%, with an average of 0.5% per year.

Solar panels with an average of 0.5% degradation rate will continue to operate at 88% of their original capacity after 25 years. This means that solar panels will continue to produce energy long after their lifetime, just at a slightly lower capacity.

Do Solar Panels Require Maintenance?

Solar panels are now produced to be incredibly reliable. With the proper care and cleaning, your panels will last well over the standard lifetime. The rain is a great cleaning mechanism for your solar panels, but if you are stuck in a dry season and your panels need a touch up, all it takes is a bucket of water, a non-abrasive sponge and some soap and your panels will be clean.
