The invention relates to a distributed type photovoltaic power generation automatic tracking system. The distributed type photovoltaic power generation automatic tracking system is structurally characterized in that a fixing device is composed of a ground base frame, a vertical rod and a fixing support, a triangular solar panel welding deflection support is connected to the fixing support through a bearing, and a servo motor drives the deflection support to deflect through an upper pull rod and a lower pull rod, so that a solar panel moves with the fixing support as an axis. The solar panel is irradiated by direct sunlight to the greatest extent, so that the generating efficiency is maximized, the generating capacity can be increased by about 30% generally, installation and construction are easy, operation is convenient, and the cost is low.
