Double-mode solar-energy-tracking device

Disclosed is a double-mode solar-energy-tracking device including a horizontally-rotating stepping motor. The output shaft of the horizontally-rotating stepping motor is connected to a solar panel support provided with a vertically-rotating stepping motor and a solar-panel rotation shaft. The solar-panel rotation shaft is provided with a solar panel. A control module is connected with a GPS module, and the four sides of the solar panel are each provided with a photosensitive sensor. Through calculation based on the local latitude and longitude and time information obtained by the GPS module, the double-mode solar-energy-tracking device obtains the local altitude angle and the azimuth angle of the sun at the moment and controls the angle and direction of the solar panel through cooperation of the horizontally-rotating stepping motor and the vertically-rotating stepping motor; and the double-mode solar-energy-tracking device can also precisely control the pitching angle and the azimuth angle of the solar panel through the photosensitive sensors on the solar panel so that the sunlight is tracked in a real-time manner through double modes and power generation efficiency of the solar panel is improved.
