The industry standard for the productive lifespan of a solar panel is 25 to 30 years. However, a solar panel will not die after 25-30 years, but its production will drop significantly below what the manufacturer projected. Solar panels, also known as photovoltaic or photovoltaic panels, are built to last more than 25 years. In fact, many solar panels installed as early as the 1980s are still operating at the expected capacity, 1 Not only are solar panels remarkably reliable, but the longevity of solar panels has increased dramatically over the past 20 years, 2 In addition to decades of effective performance, many solar manufacturers support their products with performance guarantees in their warranties, 1.Based on this information, solar panel manufacturers typically offer warranties of approximately 25 years or more.
And for newer or well-built systems, the panels can last 30 years. The average solar panel loses 0.8% of its production each year according to a study by the National Renewable Energy Laboratory (NREL). However, premium manufacturers such as SunPower offer panels with degradation rates as low as 0.3%, which means their panels will last much longer compared to most other manufacturers. This makes the degradation rate a vital aspect to consider when comparing solar panels during the pre-purchase research process.
Solar panels last about 20 years, says Federal Trade Commission. But the answer is much more than that. The exact number would depend on several factors, such as the type of panel, the way the system is installed, the climate in which you live, and the maintenance. The good news is that, with proper maintenance, your panel can work for up to 40-50 years.
Read on to learn how you can make your panel last as long as this. So what happens after the 25-year mark ends? Panels that produce 80% efficiency still work, right?. The average break-even point for energy savings of solar panels occurs six to 10 years after installation. If the panels continue to produce at a high level for another 15 years after that, you'll end up saving thousands of dollars over the lifespan of the solar panels.
Even though quality solar panels are built to withstand high winds, heavy snowfall, and even inch-sized hail that falls at about 50 miles per hour, you still need to keep them clean at all times. But as long as your solar system is expertly installed and you use good quality panels, this shouldn't contribute much to degradation. Solar panels can be an important financial investment, especially when you need to buy a large number of them for your home. Once I get a solar panel installer to help us with this, I'll be sure to use their tips to keep it well.
In this blog, we'll explain how long solar panels last, discuss solar panel degradation rates, and ways to ensure your solar panels last as long as possible. Solar panel systems will continue to produce electricity even after the 25-year warranty period if they are well maintained. Solar panels aren't immune to this, and it's that constant coming and going that puts them under pressure and creates those little cracks. While solar energy is a relatively worry-free investment, regular maintenance reviews and cleaning can also help extend the life of solar panels.
Taking into account the climate in your area will help you organize your solar panels so that they support sufficient airflow, thus keeping them at the right temperature for optimal operating conditions. To avoid situations like this, it is advisable to regularly clean the solar panels or install insect protectors on the solar panels. Solar engineers will need to consider the connection system as well as the condition of a roof when arranging solar panel arrays.

The European Union Waste Electrical and Electronic Equipment Directive requires producers to finance end-of-life treatment of solar panels sold in Europe. If your solar system pays for itself and your panels continue to produce, your ROI will far exceed the estimate provided by online calculators (including ours). Solar panels are generally quite easy to maintain because they are built to withstand weather events such as snow, hail, and wind. .
