Description

Technical Field

[0002] Solar energy is a renewable energy source, which refers to the thermal radiation energy of the sun. Its main manifestation is the so-called sunlight. In modern times, it is generally used to generate electricity or provide energy for water heaters. In order to better absorb and utilize solar energy, photovoltaic panels are used to absorb solar energy. Since photovoltaic panels are placed outdoors for a long time, a lot of dust will adhere to the surface. When there is too much dust, it will affect the photovoltaic panels' absorption of solar energy. Therefore, the photovoltaic panels need to be cleaned regularly.
