Embodiment Construction

[0030] In the present invention, in order to realize the uniform and high-multiplier condensing of the flat mirror reflection type, the photovoltaic cell 3 placed on the desktop adopts a rectangular structure. The reflector adopts a recliner-like rectangular plane structure, and the four corners between recliners adopt rectangular or rhombic plane mirrors, which are concentric and symmetrically placed around the photovoltaic cell 3 "desktop" to reflect the vertical incident light from the sun. The four frontal orientations use 1 to 4 flat rectangular mirrors with different inclination angles ( figure 1 The middle is 3), forming a recliner-like reflective structure, and the angle is selected through geometric design. The angle between each plane mirror and the horizontal plane ensures that the sunlight perpendicular to the photovoltaic panel surface is evenly reflected on the panel plane. Square or rhombus plane mirrors are used in the four angles between the recliner's reflectin...

The device has the advantages of high light collection efficiency, low cost, simple structure, low energy consumption, low pollution and easy cleaning.

Description

Technical field [0001] The invention relates to a solar power generation device, in particular to a reflective solar power generation device with uniform and high-power light collection. Background technique [0002] Solar energy has the characteristics of low distribution density, dramatic changes in light intensity with climate and time, large randomness, and low photoelectric conversion efficiency of photovoltaic devices, which has led to the high cost of solar energy utilization, making the expensive price restrict the large-scale use of solar energy . In the cost structure of solar photovoltaic power generation, solar cell modules account for about 50%, inverter power supplies and storage batteries are about 20-30%, and installation costs are 20-30%. Taking silicon solar cells, which currently account for 90% of the market share, for example, the prices of monocrystalline and polycrystalline silicon have risen rapidly in recent years. [0003] At present, the photoelectric c...
