Abstract

The invention relates to a dish type high-multiple concentrating photovoltaic generating device which comprises a plurality of gallium arsenide photovoltaic batteries, a gravity type heat pipe radiator, a dish type high-multiple concentrating lens, a photosensitive probe, a control cabinet and the like. The photosensitive probe is used for detecting the sun at any time, a programmable controller in the control cabinet is used for receiving the signals of the photosensitive probe, and then control signals are outputted to a horizontal rotating mechanism and a tilted rotating mechanism after being processed to drive a bracket and drive the dish type high-multiple concentrating lens to adjust a horizontal direction and a tilted angle at any time, thereby ensuring that the sun is accurately tracked. The dish type high-multiple concentrating photovoltaic generating device is suitable for different weathers, such as sunny days, cloudy days and the like, and has the characteristics of higherphotoelectric conversion efficiency, light weight, convenience of installation, long-term stability and running safety.

Description

technical field [0001] The invention relates to a solar photovoltaic power generation device, in particular to a dish-type high-magnification concentrating photovoltaic power generation device. Background technique [0002] Traditional flat-panel photovoltaic power generation systems use large-area crystalline silicon cells to convert solar energy into electrical energy. Since the conversion efficiency of crystalline silicon cells is not high, generally only more than ten percent, if a large amount of electric energy is to be obtained, a large number of crystalline silicon cells must be equipped. At present, the price of crystalline silicon flat panel batteries is relatively high, and the cost of panels accounts for most of the cost of power generation. [0003] In order to overcome this shortcoming of traditional flat photovoltaic cells, concentrators can be used to gather sunlight, so that more electricity can be obtained on the same area. There are many concentrators cu...
