However, the efficiency of photovoltaic power generation is limited all the time, and one important reason is that the performance of the photovoltaic panel is inversely proportional to the temperature range, the more the temperature of the photovoltaic panel rises, the lower the power generation performance of the photovoltaic panel is, however, this is in contradiction with solar power generation, and when the sunlight is stronger, the more solar energy the photovoltaic panel absorbs, the more heat emitted is necessarily increased. This conflict greatly limits the practical performance of the photovoltaic panel. Although the laboratory theoretical power generation efficiency of the current photovoltaic panel can reach 30% or even higher, the outdoor actual power generation efficiency is often only half or even lower. Meanwhile, the phenomenon that the photovoltaic power generation efficiency of a region with strong sunlight is basically the same as that of a region with weak sunlight also occurs, for example, scientists statistically find that the power generation efficiency of the same solar photovoltaic power generation panel in the United kingdom is basically consistent with that in Egypt. This also greatly wastes high quality solar energy resources.
Therefore, photovoltaic power generation needs to be considered as cooling of the photovoltaic panel, but due to the fact that the photovoltaic panel is large in area and small in energy density, the cooling effect and the cost of a cooling system are difficult to simultaneously consider. Meanwhile, the traditional air-cooled running water cooling system needs to consume certain electric energy, so that the efficiency is not high and the photovoltaic power generation system with dispersed area is more disadvantageous. At present, researchers study a PV/T system, namely a photovoltaic power generation and waste heat combined application system, the system collects waste heat generated by a photovoltaic panel and provides hot water or other low-temperature heat, but the electric quantity and the heat of the photovoltaic system are not matched, and compared with the electric quantity generated by the photovoltaic panel, the provided hot water is too large, so that ordinary residents or markets can consume too much low-temperature heat. Further, solar power plants with rare footprints are less efficient at this heat. Therefore, a photovoltaic cooling mode which is more reasonable, more economical and has a cooling effect is also needed to be considered.
