In recent years, the average cost of solar panels has fallen by almost 70%. This cost reduction has made this green source of renewable and sustainable power more accessible to people around the country.
While this is true, if you are like most people, you probably have a few questions you want to be answered before investing in solar panels. One of the most common is, how long do solar panels last?
If you have wondered this, you are in luck. Here you can find the answer to this pressing question.
The Lifespan of Solar Panels
Solar panels, often called PV or photovoltaic panels, are designed to last 25 years or longer. Some solar panels installed in the early 1980s are still working at full capacity today.
Along with being remarkably reliable, solar panels longevity has increased significantly in the past two decades. To prove this, many manufacturers now provide performance guarantees in the warranties given with a solar panel purchase.
However, it’s important to remember that the life expectance of solar panels doesn’t mean they will stop producing electricity after a few decades. It just means the production will decrease.
The Solar Panel Degradation Rate
Something your solar installation company should discuss with you is the solar panel degradation rate.
As time, the solar panels lose the ability to absorb sunlight and convert it into solar power. This is because of factors like hot weather and the reduction of the chemical potency in the panel.
The reduction in this potency is called the degradation rate.
When buying panels, try to find options with minimal degradation rates. That means it is a higher-quality panel. It also means the panel will produce more energy over its life.
Extending the Life of Your Solar Panels
As mentioned above, solar panels are designed to be durable. Manufacturers invest in extensive testing to ensure their panels can withstand heavy snow and high winds.
Some panels are even tested to see how they perform in hail.
Modern solar panel systems don’t have many moving parts either, which minimizes the required maintenance.
One of the best ways to ensure your solar panels last as long as possible is by hiring a professional for installation. You should also only purchase solar panel systems with generous warranties.
Also, while solar panels don’t require much maintenance, inspecting and cleaning them regularly will help reduce the degradation rate. This results in a longer lifespan for your solar panels.
