Many solar panels come with 25-year warranties, but that doesn’t mean they no longer work after that time frame. Instead, 25-30 years represents the “useful life” of solar panels, after which they degrade, but still work. Solar panel degradation can be caused by wind, rain and cold, but also by heat and sunlight (especially during their first exposure to it). One way to prevent degradation is to regularly remove debris, build-up and corrosion. Professional check-ups are also useful. It further makes sense to position them panels away from hazards such as large trees that could get knocked over.
Key Takeaways:
- Solar panels often come with 25-year warranties, but this doesn’t mean they stop working at that point.
- Solar panels degrade due to rain, wind, cold, heat and even sunlight.
- To extend the life of your panels, clean them regularly and have a professional perform a check-up.
“Once your solar panels have outlived their “useful life,” depending on your financial goals, you can choose to replace them or produce energy at a lower level.”
