The core of a photovoltaic facility is a solar panel. The semiconductor materials used to generate electricity mainly include: monocrystalline silicon, polycrystalline silicon, amorphous silicon and cadmium telluride. As countries have been actively promoting the application of renewable energy in recent years, the photovoltaic industry has developed rapidly. When installing solar photovoltaic panels, a support frame is used to support the panels at a certain angle to facilitate sunlight exposure.
