Problems solved by technology

[0003] The current solar energy utilization technology mainly focuses on photovoltaic power generation and solar thermal energy utilization. Due to the relatively expensive photovoltaic power generation and low photoelectric conversion efficiency, the application field is limited. The solar thermal energy utilization mainly focuses on various solar collectors, solar cookers and solar heat pumps. etc., but the temperature is generally low, the heat is dispersed, and it is difficult to perform thermoelectric conversion
In addition, the sunlight on the earth will be intermittent due to night, cloudy and rainy and snowy weather, and will also fluctuate with the changes of spring, summer, autumn and winter, making the solar heat source unable to provide stable and continuous supply, resulting in the power generation of the solar thermal power generation system, Unstable power supply
