Why are photovoltaic panels afraid of bird droppings pollution
Bird droppings are the most common and highest-risk trigger for hot spots in solar systems. The key problem is not the covered area but the concentrated nature and complete opacity of the shading. Why does partial shading cause an entire panel to overheat? How can a small stain impact the power output of an entire solar system? Compared to heavy rain or high temperatures, hot spots. . Bird guano accumulation is one of the environmental issues that could affect the performance degradation of solar photovoltaic modules (SPV). What seems like a minor cosmetic issue is, in fact, a serious operational problem that can cost you real money. If you're concerned about the potential consequences of bird presence around your solar array, explore this issue further with us. Anything blocking that light—like bird droppings—cuts their output.
