Common Mistakes And Misconceptions

Mistake/Misconception Correct Viewpoint
Solar panels last forever. While solar panels are durable and can last for decades, they do have a lifespan. The average lifespan of a solar panel is around 25-30 years.
Solar panels degrade quickly over time. While it’s true that solar panels will experience some degradation over time, the rate at which this occurs is relatively slow. Most manufacturers guarantee that their panels will still produce at least 80% of their original power output after 25 years of use. Proper maintenance and cleaning can also help to slow down the degradation process even further.
All solar panels are created equal in terms of lifespan. Different types and brands of solar panels may have varying lifespans depending on factors such as materials used, manufacturing processes, and quality control measures in place during production. It’s important to research different options before making a purchase to ensure you’re getting a high-quality product with a long lifespan expectancy.
Extreme weather conditions can significantly reduce the lifespan of solar panels. While extreme weather events like hailstorms or hurricanes can damage individual cells within your panel array, most modern systems are designed to withstand harsh environmental conditions without significant loss in performance or longevity.
Once installed, there’s no need for any maintenance on your system. Solar panel systems require regular maintenance just like any other electrical equipment; however, it’s minimal compared to traditional energy sources since there aren’t many moving parts involved with generating electricity from sunlight! Regular cleaning (at least twice per year) helps keep dirt buildup from reducing efficiency while checking connections ensures everything stays connected properly so nothing gets damaged due to loose wires or corrosion over time.
