The consequences of not cleaning photovoltaic panels for ten years
A study by the National Renewable Energy Laboratory (NREL) found that dirty solar panels lose an average of 25% efficiency annually without cleaning. Dust and debris trap heat, accelerating wear and tear. NASA research confirms that 1g/m² of dust causes a 5% power loss, while severe pollution can push losses above 30%. Even worse, bird droppings and dust accumulation accelerate solar panel aging and trigger hotspot. . Keeping panels clean can help avoid physical damage and extend their lifespan.
