When debris, such as leaves, dirt, or other types of buildup, accumulates on the surface of your solar panels, it can block sunlight from reaching the cells. They turn sunlight into clean electricity. As interest in sustainable energy grows, keeping solar panels efficient is important. A current of electricity is produced when sunlight strikes the panel because the photons in the light energy dislodge electrons from atoms. However, one often-overlooked factor significantly impacts their efficiency: 𝐝𝐮𝐬𝐭 𝐚𝐧𝐝 𝐝𝐞𝐛𝐫𝐢𝐬 𝐚𝐜𝐜𝐮𝐦𝐮𝐥𝐚𝐭𝐢𝐨𝐧. Even a light layer of dust can block enough sunlight to reduce energy production by 5–10%, and heavy buildup from events such as sandstorms. . Solar panels are exposed to the elements, making them vulnerable to dirt, dust, pollen, bird droppings, and other debris.
