Description

technical field [0001] The invention belongs to the field of solar energy, in particular to a distributed solar heat and power cogeneration energy system. Background technique [0002] Solar energy has huge reserves, is clean and safe, and is an ideal alternative energy source for fossil fuels such as oil and coal. Solar photovoltaic power generation is an important way of solar thermal utilization, but high cost and low efficiency are important factors restricting its development. Solar photovoltaic power generation is a technology that directly converts light energy into electrical energy by using the photovoltaic effect of the semiconductor interface. It has the advantages of high conversion efficiency and low cost. However, the injection of high light intensity causes photovoltaic cells to generate a lot of heat. If the heat is not removed in time, the conversion efficiency and reliability of the cells will drop rapidly and the service life will be shortened. [0003] ...
