Many people install solar panels to reduce energy costs but may be concerned about how long the system will last. While it’s true that solar panels don’t last forever, there are things you can do to maintain and extend the life of your solar panels.
The most important thing is to regularly check your solar panel system for signs of damage or wear and tear. A professional can help you identify and address problems before they become serious.

Clean Your Panels Regularly
Clean solar panels like those at experts like EMT Solar are essential for optimum energy production. Dust and dirt can block sun rays from reaching the solar cells, which decreases overall energy conversion. A typical bit of dirt or leaves can cause a 5% decline in energy production over a year, so cleaning your panels regularly is an effective way to maximize their performance.
Solar panel cleaners are affordable and available at most home improvement stores. However, it is essential to note that harsh chemicals or abrasive sponges can damage your solar panels. This can reduce their energy output and potentially void your warranty.
Before cleaning your solar panels, ensure the system is powered down per manufacturer instructions, and you have a safe place to work from. Also, be careful not to touch or work on the batteries if the power is still on.
Keep the Area Around Your Panels Clean
A clean solar panel is more efficient and produces more electricity than a dirty one. This is why cleaning and maintenance are so important.
Many factors can affect how dirty your panels get, from the weather and pollution to the roof’s pitch and whether you have deciduous trees that drop leaves in fall. But generally, the more sun they see, the cleaner they will be.
Keeping your PV system clean is easy with a garden hose or telescopic spray wand, but it’s best to avoid putting too much water pressure on them as this can crack your PV panels. Also, don’t spray cold water on hot panels, which can cause a sudden temperature shock and damage your solar systems. This is why cleaning your solar panels early or on a fantastic, overcast day is best.
Keep Debris Away from Your Panels
When dust accumulates on solar panels, it interferes with sunlight absorption. Over time, this can lead to a significant reduction in performance. It can also cause damage to the underlying materials.
You can avoid this by keeping debris away from your panels. For example, if you live in an area with many trees, keeping their branches away from your PV system is essential. This can help prevent falling leaves and other debris from hitting your solar panels and reduce the risk of bird droppings getting on them.
If you need to clean your solar panels, working from the ground instead of climbing up on your roof is best. A garden hose is the best option, but you can also use a telescopic hose wand for extra spraying control. You should also use non-abrasive cleaning products that are safe for solar panels. Also, try to do your cleanings during excellent hours of the day. This will help ensure your panels don’t dry out and leave water stains behind.
Check Your Panels for Damage
Even though solar panels are rated to last up to 25 years, they are not indestructible. They are subject to regular wear and tear that comes with converting sunlight into energy, but it is essential to know the signs of damage so you can act fast before things worsen.
Physical damage can occur in several ways, from shattered glass caused by hail storms to cracks that form due to extreme temperature changes. These cracks can speed up the degradation of your panels by blocking sunlight and reducing their energy absorption.
Suppose you have a power purchase agreement or are working with a maintenance provider. In that case, they can thoroughly inspect your panels and catch any issues affecting their performance before they get out of hand. Using a multimeter, they can test your panels to see how much power they are producing and compare them against their stated specifications.
Take Care of Your Panels in Harsh Weather Conditions
Keeping your solar panels clean can prevent dirt and debris from building up on the surface, affecting how well they function. It will help if you clear away any snow accumulating on the panels during the winter, as too much snow can reduce the energy your panels generate.
In addition, it is a good idea to install a protective system for your panels. While there are many different options available, it is essential to choose a cover that will allow sunlight through while also being able to withstand hail and other severe weather conditions. A simple solution is using a spray-on monomer such as methacrylate, which can protect your solar panels without reducing efficiency.
By following these tips, you can extend the life of your solar panels and ensure that they continue to produce electricity at total capacity for years to come. If you have any questions about how to take care of your solar panels, contact a reputable solar energy provider.
Check Your Panels for Defects
Solar panels are a big investment, and you want them to continue producing energy for decades. That’s why it’s essential to research and take the necessary steps to keep them in good condition.
One issue that can impact the lifespan of your solar panel is delamination. This occurs when a layer of plastic on the rear surface of your solar panel starts to peel away from the rest of the PV module. This can lead to reduced power generation, so if you notice any signs of delamination, contact your installer immediately.
Micro-cracks throughout crystalline PV modules are another common issue. These cracks are invisible to the naked eye, but they can cause a reduction in energy absorption over time. They can also result in hot spots, indicating that your panel may suffer from Potential Induced Degradation (PID). Check with your installer about the best ways to test for this problem.
