Solar photovoltaic refrigerators mainly include solar photovoltaic refrigerators and solar semiconductor refrigerators. Solar photovoltaic refrigerator is developed on the basis of conventional compression refrigerator, which is composed of solar cell, controller, battery, refrigerator and other components. The solar semiconductor refrigerator mainly includes solar cell array, controller, battery and semiconductor refrigeration device. The solar cell array is located on the top surface of the sun or refrigerator. One end is connected with the controller set on the front side of the refrigerator through wiring, and the other end is connected with the hot end of the semiconductor refrigeration device set on the other side of the refrigerator through the controller, and the other end is directly connected with the half The cold end of the conductor refrigeration device is connected, one end of the battery arranged in the refrigerator is connected with the controller, and the other end is connected between the solar cell array and the controller.
