When you invest in something as significant as solar panels, you want to know that they will survive for an extended period. A good set of panels will last around 25 to 30 years in total, although they may still operate after that. This is all you need to understand about how long your solar panels will last.
Please remember that just because your solar panels are predicted to last a couple of decades doesn’t imply they’ll stop producing electricity. It means that their energy production will be reduced by the amount that solar panel manufacturers believe is necessary to meet the energy needs of the ordinary American family.
Photovoltaic (PV) panels, commonly known as solar panels, are designed to last for more than 25 years. Many solar panels that were placed as early as the 1980s are still operating at full power. Solar panels are not only incredibly dependable, but their lifespan has risen substantially in the previous 20 years. Many solar manufacturers back their equipment with performance guarantees in their warranties, in addition to decades of successful performance.
How long do solar panels last?
In normal circumstances
You may expect your solar panels to endure decades under typical conditions. They will not stop producing electricity after 25 years, but their production rate will begin to decline. You may expect the panel to last long if it is not harmed by an outside factor such as water or wind.
The best way to extend the life of your solar panels is to get them maintained by your installers regularly. Maintaining the panels will result in higher output rates that do not decline over time, so you should take advantage of the services provided by your manufacturer.
You will probably have more experience with your solar panel if you live in a calmer environment. It will hold up exceptionally well when it is not at risk of being damaged by debris. It’s always important to remember that solar panels are built to last.
In Harsh Environments
But how does the solar panel perform in less-than-ideal conditions? Although high-quality panels can resist adverse conditions, they may not yield as much energy. On days with a lot of cloud coverage, they often reduce their production rates to 10% to 25%.
Even if you reside in a location with a lot of rain, you should expect decent output rates. This is because the panels continue to perform even when they are wet, and the rain even clears them of debris, allowing them to create more power – as long as the cloud coverage isn’t too high.
High winds will not affect your solar panels. This is because all manufacturers must have their products pass a test against wind speeds of 140 miles per hour, which is only found in a Category 4 hurricane. Your panels and roof will be fine as long as the wind in your location isn’t too strong all the time.
Nevertheless, any electronic item, including solar panels, can be damaged by lightning. Your installer will ensure that the solar system is protected from lightning. Grounding the panels is usually part of this, but you may need to take the necessary measures depending on your environment.
On The Roof vs Off The Roof
On the Roof
Roof-mounted solar panels take up less area and are less expensive to install. However, depending on your roofing and the direction they must face, they may be more or less efficient.
Solar panels placed on the roof are typically more difficult to diagnose if something goes wrong because your installers will need to access them from the roof. But don’t let that discourage you.
Roof-mounted panels utilize fewer resources, take up less space, and are far more cost effective in the long run. Their lifespan is still estimated to be between 25 and 30 years, during which they will give you pure energy.
Off the Roof
For some, putting your solar panels on the ground is an alternative. Because they are easier to access and maintain, they have a little longer life. They may also maintain a higher energy production for more prolonged periods since the ground is cooler.
However, where you reside will have the most impact on the type of panels you receive. If you live in a city with limited space, you’ll probably be allowed only to have the panels installed on your roof. Ground-mounted panels may be possible if you have the space; however, they are more expensive upfront.
Can You Make Solar Panels Last Longer?
If you want them to endure as long as possible, take advantage of any additional services the installer may provide. They know exactly what to do to keep your panels producing at a high rate for years.
If something goes wrong with your solar panels, your installer will be able to fix or replace them under warranty. Production guarantees can last up to 25 years and ensure that your system produces at a specific rate.
If they don’t meet the required production rate, the installer will have to adjust your panels to meet the rate, ensuring that you get 25 years of life and power out of them.
Keep Debris Away
Lastly, you’ll want to make sure your solar panels are clean of trash as much as possible. Debris such as leaves, dust, and pollen can stifle production or cause your solar panels to deteriorate over time.
Critter guards are available from some manufacturers, which prevent critters from residing beneath the panels. Small animals, on the other hand, can wreak havoc on your system’s wiring and cells.
Solar panels will endure many decades if you take the time to preserve them from physical damage. If there are any more actions, you need to follow, make sure to ask your manufacturer.

Is It True That Solar Panels Degrade Over Time?
Solar panels, like most technology, will produce less energy with time. The degradation rate refers to the reduction in power production. The median solar panel degradation rate is around 0.5 percent per year, which shows that the energy output of a solar panel will drop by 0.5 percent every year. 3 Your panels should still be producing around 90% of their original output after 20 years.
When it comes to solar panels, how long do they last? They have a 30-year lifespan, which is a considerable length of time. They can withstand the elements as long as they are clean and free of debris. This applies to both taxing and non-taxing situations.
When you compare solar panels to electric generators, you find that this eco-friendly way of producing power has a much longer lifespan. So why not switch to solar panels today? Check out the product and reduce your carbon footprint.
