Photoelectric and photo-thermal integrated equipment

Abstract

The invention relates to a photovoltaic-photo-thermal system, in particular to a photovoltaic and photo-thermal integrated device. According to the invention, photovoltaic power generation and photo-thermal are combined together; a cold and hot adjusting flow channel is connected with a water tank, a photovoltaic panel is kept at the proper temperature (about 25 DEG C) for high photoelectric conversion, when the temperature of the photovoltaic panel is too high, the cold and hot adjusting flow channel transmits heat to the water tank through a cooling pipe, the water tank generates hot water,meanwhile, it is guaranteed that the photovoltaic panel is rapidly cooled for a long time, and the service life of the photovoltaic panel is effectively guaranteed; when the temperature of the photovoltaic panel is low, a heating wire arranged on a bottom surface of the photovoltaic panel can be used for carrying out auxiliary heating on the photovoltaic panel, and meanwhile, the temperature risecurve of the photovoltaic panel is stable and controllable such that the temperature of an upper surface of a to-be-heated substrate is more uniform and constant. According to the photovoltaic and photo-thermal integrated equipment, the conversion efficiency of the photovoltaic cell and the photo-thermal and photoelectric conversion performance can be improved, the solar energy conversion efficiency in unit area is improved, the solar energy utilization efficiency is improved, and the generating capacity is increased.

Description

technical field [0001] The invention belongs to the field of photoelectricity, light and heat, and in particular relates to a kind of photoelectricity, light and heat integrated equipment. Background technique [0002] As a new energy source, solar energy has the advantages of being inexhaustible, clean and environmentally friendly compared with traditional fossil fuels. However, the existing solar energy utilization has the disadvantage of being too single. After investing a lot of manpower, material and financial resources, it can only grab a single energy source. Generally, a large amount of heat energy will be generated in the process of converting solar energy into electrical energy, and this part of wasted heat energy It will affect the voltage drop of the whole module, affect the power generation efficiency of the whole module, and in the case of no sunlight or low room temperature, it will also affect the power generation efficiency of the photovoltaic module, which ...
