The working principle of the sun chasing photovoltaic mount is based on the light control solar tracking technology, 

using the sun's light ray guidance, through the crystalline silicon and gallium arsenide photosensitive devices to collect signals, 

and then through the digital circuit to control the main circuit, with stepping motors or servo motors to drive tracking device, 

in order to realize the accurate tracking of the sun's trajectory. Sun chasing PV mounts can automatically track the sun's position

 without being affected by weather factors, maximizing the utilization rate of solar energy collection.
