Bird droppings on solar installations are considered the most stubborn and aggressive form of soiling to affect photovoltaic modules. Under intense sunlight, the acidic droppings can burn into the glass and cause so-called hot spots. Photovoltaic modules enjoy zero protection against environmental and weather-related influences, 24 hours a day.
However, they bring a challenge that is often overlooked: bird droppings and nesting. Birds are attracted to the protected space and warmth of the solar panels, which can provoke damage with their droppings, causing energy reduction and blocking sunlight.
“Bird poop can really mess up the amount of green energy that can be produced by solar panels,” Koh said, with absolute seriousness and sobriety.
Bird droppings, Koh explained, when built up on a solar panel, can block sunlight from reaching the cells. This doesn't just make the panel less efficient but also creates hotspots – areas on the panel that overheat because they don't get enough sunlight.
