Solar energy comprehensive utilization apparatus

Abstract

The invention discloses a solar energy comprehensive utilization apparatus that comprises a photovoltaic generating assembly, a temperature difference generating assembly, and a cooling device. The photovoltaic generating assembly receives solar radiation and converts solar energy into electric energy. The temperature difference generating assembly, which is arranged at a backlight side of the photovoltaic generating assembly, is used for converting heat energy that is from the photovoltaic generating assembly into electric energy; besides, the temperature difference assembly includes a hot end and a cold end that is at an opposite side of the hot end, wherein the hot end is contacted with the backlight side of the photovoltaic generating assembly. The cooling device, which contains fluid medium, is arranged at one side of the temperature difference generating assembly and is contacted with the cold end of the temperature difference generating assembly; moreover, the cooling device enables the cold end of the temperature difference generating assembly to be cooled by circulating the fluid medium as well as thermal fluid medium is generated for utilization. According to the invention, a modularized solar energy generating and heat recovery and utilization apparatus is established, thereby realizing high efficient solar energy generating efficiency and electric heating comprehensive utilization efficiency.

Description

technical field [0001] The invention relates to the field of solar energy utilization, in particular to a solar energy comprehensive utilization device. Background technique [0002] In recent years, building integrated photovoltaics has increasingly become an important means to achieve building energy conservation and composite energy development. However, in the application process of photovoltaic cells, the utilization efficiency of solar energy in the process of photovoltaic power generation is generally low, and nearly 80% of the solar radiation energy is lost in the form of heat and cannot be effectively utilized; and in the process of photovoltaic power generation, due to the The increase in temperature also causes a decrease in the efficiency of photovoltaic power generation and shortens the life of photovoltaic cells. Therefore, in the process of photovoltaic power generation, how to improve the comprehensive utilization of solar energy has always been a practical ...
