[0002] Photovoltaic power generation is a direct power generation method that uses semiconductor electronic devices (also known as photovoltaic panels, solar panels) to effectively absorb solar radiation energy and convert it into electrical energy. It is the mainstream method of solar power generation today. Usually, photovoltaic panels are mounted on photovoltaic brackets to receive solar radiation. Since the incident angle of the sun changes, the photovoltaic panels also need to adjust the angle accordingly to maximize the exposure of sunlight to the photovoltaic panels.

[0003] Photovoltaic brackets are generally fixed or tracking types. The construction and maintenance costs of tracking photovoltaic brackets are too high, and their promotion is limited. Although fixed photovoltaic brackets have low costs, they cannot fully utilize solar energy due to the different altitudes of the sun in different seasons.
