Description

technical field [0001] The invention relates to the field of solar photovoltaic technology, in particular to a solar photothermal utilization system. Background technique [0002] Photovoltaic is defined as the direct conversion of ray energy. Usually refers to the process of converting solar energy into electrical energy. This conversion mainly uses solar panels made of semiconductor materials such as silicon. Solar panels use light to convert solar energy into electrical energy to generate direct current. Since solar photovoltaic does not need any other "fuel", it only needs sunlight to work, so it is called green energy, green and pollution-free. [0003] The parallel light of the existing solar photovoltaic sunlight directly shines on the cells or vacuum tubes, and can only generate direct current through photovoltaic panels to achieve the purpose of power generation, or can only generate hot water. In the prior art, ordinary solar photovoltaics do not The combination...

Problems solved by technology

[0003] The parallel light of the existing solar photovoltaic sunlight directly shines on the cells or vacuum tubes, and can only generate direct current through photovoltaic panels to achieve the purpose of power generation, or can only generate hot water. In the prior art, ordinary solar photovoltaics do not The combination of the two technologies does not maximize the utilization rate of solar energy. After photovoltaic cells absorb the transmitted sunlight, less than 20% of it is converted into electrical energy, and the rest is converted into heat and finally lost in the air, thus making a large part of the solar energy The solar energy is lost, resulting in a waste of energy, so it is necessary to design a solar thermal utilization system to solve the above problems
