Yes, dust can indeed affect solar panels. Dust particles can accumulate on the surface of solar panels and obstruct sunlight, thereby reducing the panels' efficiency and energy output.
Strong winds can carry dust particles and deposit them on panel surfaces, while rainfall can naturally clean off accumulated dust. Areas with infrequent or irregular rainfall patterns may require more frequent manual cleaning to maintain optimal performance.
This review examines the impact of dust on PV performance and evaluates cleaning approaches, including electrostatic removal, super hydrophobic and super hydrophilic coatings, surface acoustic wave (SAW) technology, robotic systems, and manual methods.
Dust and dirt can block sunlight, causing a reduction in solar panel efficiency by up to 6%. Regular cleaning can restore up to 95% of original power after maintenance.
