The answer largely depends on how you take care of them. Solar panel maintenance consists of keeping the panels clean and free from debris, like leaves or dirt. Companies that provide solar systems usually offer their clients a maintenance plan to ensure their system is running at its maximum capacity. Additionally, it’s important to assess your solar panel array every couple years to make sure no panel is overproducing or underproducing from the others in your array. This can cause a decrease in efficiency and should be addressed as soon as possible.
By taking proper care of your solar panel system, you can ensure that it will last anywhere between 25-30 years and continue to produce energy for many years after that.
How much do solar panels degrade over time?
Solar panels don’t really degrade over time. Rather, their efficiency decreases as they become covered in dirt and debris, or are subjected to extreme temperatures or weather conditions. While the average rate of degradation is 0.30%-0.80% annually, proper maintenance and cleaning can help keep that number down.
Factors that can affect the lifespan of your solar panels
- Temperature – Extreme temperatures can cause solar panels to deteriorate over time, so it’s important to make sure they are installed in well-ventilated areas.
- Quality – Higher quality solar panels tend to last longer than their cheaper counterparts due to better construction materials and processes.
- Installation – Poorly installed solar panels can cause catastrophic failures in the system, shortening its life span.
- Maintenance – Keeping your solar panels clean and free from debris will help to extend their life. Regular maintenance can also catch small problems before they become larger ones.
How are solar panels recycled?
Solar panel recycling is still a relatively new practice, but there are already programs in place to encourage the responsible disposal of solar panels. According to one study, up to 98% of the materials used in solar panels can be recycled, including glass, plastics and metals. These materials can then be put back into production for other uses. To find out more about recycling your solar panels, you can check with your local solar service provider.
Summary
It’s important to keep in mind that the lifespan of solar panels largely depends on how they are taken care of and the environment they are placed in. Taking proper care of your system will help ensure that it lasts for 25-30 years and continues to generate energy for many more. Additionally, programs are in place to help recycle solar panels responsibly and keep their materials out of landfills. With proper maintenance and care, your solar panel system can last you a long time!
