This invention relates to a type of solar energy photo-voltaic power generation equipment that can automatically track the sun. This device includes a pedestal installed on a mounting platform. On the pedestal, a main support frame is provided. On the support frame, a solar cell panel platform is provided. On this platform, a solar energy photo-voltaic assembly is installed. The pedestal is connected to the mounting platform and can rotate relative to the mounting platform. On the pedestal, a circumferentially driven planet reduction gear is installed. On the main support frame, a platform elevation angle adjustment lifter is installed. The end of the telescopic link on the lifter is hinged to the solar cell panel platform. The circumferentially driven planet reduction gear and platform elevation angle adjustment lifter are connected to an electric control device.
