Embodiment Construction

[0030] In the present invention, the photovoltaic cell 3 placed on the desktop adopts a rectangular structure in order to realize flat mirror reflective uniformity and high-magnification concentrating light. The reflector adopts a reclining chair-like rectangular planar structure, and the four corners between the reclining chairs adopt rectangular or diamond-shaped planar mirrors, which are concentric with the photovoltaic cell 3 "desktop" and placed symmetrically around to reflect the vertically incident light from the sun. The four front orientations adopt 1 to 4 flat rectangular mirrors with different inclination angles ( figure 1 There are 3 in the middle), forming a recliner-like reflection structure, and the angle is selected through geometric design. The angle between each section of the plane mirror and the horizontal plane ensures that the sunlight perpendicular to the direction of the photovoltaic panel surface is evenly reflected to the panel plane. Square or diamon...

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 collection. Background technique [0002] Solar energy has the characteristics of low distribution density, drastic changes in light intensity with climate and time, large randomness, and low photoelectric conversion efficiency of photovoltaic devices, which has led to high solar energy utilization costs, making expensive prices restrict large-scale use of solar energy . In the cost composition of solar photovoltaic power generation, solar cell components account for about 50%, inverter power supply and battery about 20-30%, and installation costs 20-30%. Taking silicon solar cells, which currently account for 90% of the market share, as an example, the prices of monocrystalline and polycrystalline silicon have risen rapidly in recent years. [0003] At present, the photoelectric conversion efficiency of mo...
