Common Mistakes And Misconceptions
| Mistake/Misconception | Correct Viewpoint |
|---|---|
| Solar panels degrade quickly and become useless after a few years. | While it is true that solar panels do experience degradation over time, they are designed to last for decades. Most manufacturers offer warranties of 25-30 years on their products, and many panels continue to produce electricity beyond this timeframe. Proper maintenance can also help extend the lifespan of solar panels. |
| All solar panel degradation is caused by physical wear and tear. | While physical factors such as weather conditions and exposure to sunlight can contribute to degradation, there are other causes as well. For example, some types of solar cells may experience a decrease in efficiency due to light-induced degradation (LID) or potential-induced degradation (PID). These issues can be addressed through proper design and installation techniques. |
| Solar panel performance degrades uniformly across all cells in the array. | In reality, different cells within a single panel or across an entire array may degrade at different rates depending on various factors such as shading or manufacturing defects. This non-uniformity can lead to reduced overall system performance if not properly accounted for during installation and maintenance processes. |
| Once a solar panel reaches its end-of-life point, it cannot be recycled or repurposed. | Many components of solar panels including glass, aluminum frames, copper wiring etc., are recyclable materials which could be used again in new products once extracted from old modules using appropriate recycling technologies available today. |
