Solar high-efficiency power generation device

The invention discloses a solar high-efficiency power generation device which comprises a pedestal, a solar cell panel, a sunshine detector, a solar cell panel rotation mechanism and a PLC. The solarcell panel is installed on a solar panel support, the solar cell panel, the sunshine detector and the solar cell panel rotation mechanism are all electrically connected with the PLC, the sunshine detector comprises a light shielding square column, four mini solar cells and a digital module, the mini solar cells are arranged in the periphery of the light shielding square column in a crossing symmetrical way, the input end of the digital module is connected to the mini solar cells, and the output end of the digital module is connected to the PLC. The crossing type light measuring structure is used, the light shielding square column in the middle enables that output voltages of the mini solar cells are different under a non perpendicular sunshine incidence state, measurement is more accurate,it can be ensured that su
