Why bird droppings cause photovoltaic panels to heat up
Bird droppings are sharp and clingy, which makes them notably harmful. This strain might cause tiny. . Bird droppings may look like a slight bother, but they can spark major issues for your solar panels over time. Solar panels need sunlight to create electricity. Rain or snow in winter naturally cleans the system. However, if the roof and solar panels are directly under a branch, the modules can be consistently covered with bird droppings. “Since the solar cell beneath the droppings is partially. . They're triggering "hotspots"—dangerous localized overheating zones that can reduce your energy output by 30% or more. And worst of all, by the time you notice your power bill creeping up, the damage might already be done. Therefore, the thermal behavior of SPV modules under different accumulations of bird guano (1, 2, 3, and 4 drops) has been investigated and evaluated.
