Solar panels can be a great investment for any home. However, before you go to the trouble of installing them, you might want some assurance that your investment will have a long-term payoff. How long do solar panels last?
How Long Do Solar Panels Last?
Whether you’re thinking about leasing solar panels or purchasing them for a permanent installation, you likely want to be sure that your investment will pay off before you take the plunge. So how long do solar panels last? The answer to that question is actually more complicated than you might realize.
The Average Active Life of a Solar Panel
If you just want to know how long the hardware will last, you’ll be happy to know that solar panels are made to go the distance. They are made of tempered glass and built to withstand the elements. They also don’t have moving parts or other elements that can easily degrade with time. If they’re properly installed and not affected by adverse weather conditions or accidents, they’ll continue to work for decades. Once your solar panels are in place, they will reliably produce electricity for your home for between 25 to 35 years.
What Happens After That?
As long as a solar panel is able to soak up the sun, it will continue to store and create electricity for you. However, the efficiency of the battery will degrade over time, and it will produce less electricity overall. According to industry experts, an average solar panel puts out .08 percent less electricity every year they are in operation. So if you have a 25-year-old solar panel, it will still be functional, but it will not be as efficient as a newer model.
Is There a Way to Make My Solar Panels Last Longer?
If you want to try and get the most life possible out of your solar panels, here’s what the experts recommend:
- Buy quality technology from a reputable sales outlet, and have it installed by experienced technicians. Sometimes solar panels fail earlier than predicted because they’re installed incorrectly.
- Have your solar equipment regularly checked for functionality. Keep an eye on your solar array’s typical output, and have the equipment checked if you notice significant changes.
- Solar panels don’t need to be cleaned frequently, but they work better if they’re kept clear of debris. Use a long-handled cleaning implement to safely remove leaves or other weather-related debris from your solar array. If it is visibly dingy or dirty, consult with your solar panel’s documentation for cleaning tips, or contact a solar professional for assistance.
- If you notice your solar panels are putting out less energy than usual and you aren’t sure why, be sure to look for things that could be blocking your array’s access to sunlight, like shade from trees or other sources. Shade interference can lower a solar panel’s effectiveness by up to 25 percent.
Technology continues to improve all the time, and solar panels with lower degradation rates are now available. If your solar panels are approaching the end of their useful lifespan, it may be time for an upgrade. If you’re interested in purchasing new solar panels or upgrading your existing technology, talk to an expert about what’s available today.
