Why Do Solar Panels Degrade. The period of degradation is measured against the lifespan of. Cracked solar cells are signs of poor production quality.
The primary causes of solar panel degradation are thermal shock, heat, and humidity as well as exposure to light, weather elements, and deterioration of the components in the panel over. After 30 years, it will certainly run at 81 % of its initial capacity. Solar panels are exposed to the elements 24/7, and this exposure takes its toll.
