How Long Do Solar Panels Last? A Basic Guide for Homeowners
With demand for solar energy systems in America growing by almost 24% each year, now is the ideal time to look into installing solar panels for your home.
If you are here, it probably means that you already know about the many benefits of installing solar panels from Solar Quote.
What you might still be asking, though, is how long do solar panels last?
The answer to this question isn’t as simple as you might think. From the type of solar panel you are using to where you live, there are a lot of factors that affect the lifespan.
Read on to discover what the average lifespan of solar panels is as well as what you should do to make them last longer!
How Long Do Solar Panels Last On Average?
Solar panel lifespan can vary dramatically, but the Federal Trade Commission estimates that they should last for about 20 years.
This figure is a good place to start, but the truth is that there is no set number of years your solar panels will definitely last for.
It is important to note that this doesn’t mean that after 20 years your panels will stop producing electricity. Rather, it means that their energy output will have decreased below what is needed to meet the power needs of the average American family.
You will find that many local solar companies offer 25-year warranties, so you can have peace of mind for longer.
Tips to Make Your Solar Panels Last Longer
To make the most of your solar panels, you need to ensure you perform regular maintenance on them. Here are some simple steps you can take to increase their lifespan.
Solar panels are designed to handle harsh weather conditions, but you should regularly check the panels for any signs of physical damage. Remove any debris to relieve pressure and reduce the chance of minor scratches or microcracks.
Make sure to keep your panels clean. The best way to do this is to wash them with water when you notice any buildup of dirt or debris. Even dust and sand can cause scratches and harm the panels if left uncleaned.
Finally, have your solar installer conduct routine maintenance checks by searching online solar panel installers near me. These will flag up any signs of degradation in the panels and will ensure the systems are working smoothly.
When to Replace Your Solar Panels
Even with regular maintenance and ideal weather conditions, there will be a time when you need to replace your solar panels.
If your 25-year warranty period has expired and you notice your energy bills getting higher, it may be a sign that your solar energy system is degrading. In this case, you should invest in some new panels.
It is a good idea to install an app or tracker to monitor your electricity generation levels. If you know how much energy your panels generally generate, you will know if there is a gradual decrease occurring.
Consider replacing your solar panels when they no longer produce enough electricity to power your house.
