Description

Technical Field

[0002] Photovoltaic panels are devices that convert sunlight into electrical energy. They are usually made of silicon. When sunlight shines on photovoltaic panels, photons interact with silicon atoms to generate free electrons, thereby forming an electric current. Because photovoltaic panels are generally installed at a higher position to absorb sunlight, lifting equipment is usually required to assist in the installation of photovoltaic panels.
