Abstract
Solar power generation is a clean energy source that does not emit carbon dioxide. Because solar panels of the generation system are set in the open air, dust deposited on solar panels reduces the output power. To overcome this issue we are developing an electrostatic cleaning system that utilizes a AC electrostatic field, and investigating the relationship between the removal efficiency and applied voltage, environmental conditions and the amount of dust. It has been demonstrated that this system can remove 88% of dust on solar panels and recover up to 63% of power after cleaning operation.
