A photovoltaic generation heating system based on double parabolic reflector focusing and hybrid tracking technology

A photovoltaic generation heating system based on double parabolic reflector focusing and hybrid tracking technology has been proposed in this paper. It has adopted the focusing strategy based on double parabolic uniform reflection in this system, which can not only improve the focusing ratio, but also ensure that the gathered sunlight reflect to the photovoltaic panel evenly and prolong service life of the battery. The automatic tracking technology combining calendar method with hill climbing method can speed up the tracking and enhance stability and immunity ability of the system with tracking the sun. We can get better cooling performance by using the comprehensive heat dissipation and cooling method combining infrared filter with water cooling technique. And this cooling method can increase the conversion efficiency and prolong service life of photovoltaic panel. Besides, man-machine interactive module in this system can make it conveniently for operators to conduct and debug real-time monitoring of the device. By testing the prototype, it is a system with high working efficiency, good tracking performance and low cost.
