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. Not only are solar panels remarkably reliable, but the longevity of solar panels has increased dramatically over the past 20 years. As a general rule, solar panels last between 25 and 30 years.
However, this does not mean that they stop producing electricity after 25 years, it just means that energy production has declined by what manufacturers consider to be a significant amount. Good solar panels can last between 20 and 30 years, but there isn't necessarily a date when you should immediately replace yours. It's more important to pay attention to your productivity. If your solar panels are still in good condition and produce enough electricity, they may not need to be replaced.
On the other hand, if you find that your electricity bill is going up because your solar panels no longer work, then it's probably time to replace them. You can count on most photovoltaic solar panels to last 25 years before they start to degrade noticeably. Most solar panel companies offer a standard 25-year warranty for the expected lifespan of solar panels. After 25 years, your solar panels won't necessarily need to be replaced; however, their ability to absorb sunlight will be reduced.
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.
If you notice any damage or dirt on your panels, but you can't access them safely, it's best to call a solar energy provider with the right equipment and expertise to help you. While solar energy is a relatively worry-free investment, regular maintenance reviews and cleaning can also help extend the life of solar panels. Among other industry-defined criteria, top-tier manufacturers have been producing solar panels for five or more years, have stable finances, and are highly regarded for the service and quality of their products. Still, you can do your part to extend the life of your solar panels by keeping them clean and free of debris, leaves, snow and more.
Solar panels also come with a few different warranties that can give you an idea of how long you can expect your solar panel to last. Just as a car only travels a certain number of miles or a team starts to lose contact after so many years, degradation of the solar panel is likely to occur. Degradation rates vary from brand to brand; higher quality panels have a lower degradation rate compared to lower quality panels. However, a solar panel will not die after 25-30 years, but its production will drop significantly below what the manufacturer projected.
The European Union Waste Electrical and Electronic Equipment Directive requires producers to finance end-of-life treatment of solar panels sold in Europe. 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. As long as you can avoid physical damage to your solar panels, they will continue to produce energy for many years, possibly well beyond the 25-30 year lifespan of typical solar panels. Each solar panel manufacturer offers different warranty guarantees, so be sure to read the fine print to make sure your panels are covered in any condition.
Depending on the types of shingles, a typical roof should be replaced approximately every 25 years, which is the perfect time to replace solar panels. It's really surprising that some of these solar panels are going to last around 40 years if properly maintained. All solar panels slowly degrade over time, which means they produce less electricity with the same amount of sunlight. .
