How long do solar panels last?

Most reputable manufacturers offer production warranties for 25 years or more. The average break even point for solar panel energy savings occurs six to 10 years after installation. If the panels continue to produce at a high level for another 15 years after that, you will end up saving thousands of dollars during the solar panels’ lifespan.

How long do monocrystalline solar panels last?

However, when it comes to longevity, monocrystalline panels have the upper hand. While both types of panels typically come with a 25-year warranty, monocrystalline panels have a longer lifespan. According to the American Solar Energy Society, monocrystalline solar panels last around 40 years, whilst polycrystalline models last roughly 35 years.

When do solar panels stop working?

Solar Panels don’t simply stop working after 25-30 years. They will continue to produce electricity, however at a lower rate due to panel degradation. Some brands of solar panels will continue to function long after 25 years.

Do solar panels expire?

There is technically no expiration date on solar panels. However, over time, they naturally tend to become less efficient at producing energy. Some panels can also break due to physical damage from extreme weather conditions.

How much do solar panels deteriorate a year?

The National Renewable Energy Laboratory (NREL) has been tracking degradation rates for the last several years as part of its Photovoltaic (PV) Lifetime Project. NREL’s findings indicate that solar panels have an average degradation rate of 0.5% per year.

Are solar panels durable?

Solar panels are generally very durable. Most solar panels are designed and tested to withstand the elements like hail, high winds, and heavy snow loads. And thanks to their lack of moving parts, solar panel systems usually require little to no maintenance. Still, maintaining your solar panels can boost production.
