A Review of the Mitigating Methods against the Energy Conversion Decrease in Solar Panels

Using solar panels is one of the cleanest ways to generate electricity ever created by mankind. The efficiency rapidly expanding decreases during their lifetime for several reasons, such as photodegradation, hot spots, potentially induced degradation, etc. Dirt and debris accumulation on surface can also significantly contribute performance degradation due diminishing radiation reaching active surfaces. Numerous mitigation methods are cited in literature. This article briefly outlines these basic measures.
