Description

Technical Field

[0001] The invention relates to the technical field of photovoltaic power generation, and in particular to a spherical high-efficiency photovoltaic power generation device. Background Art

[0002] Photovoltaic power generation is a recent technology that obtains green new energy through photoelectric conversion. The existing technology is restricted by many factors such as land, region, weather, and the transmission capacity of the national power grid and peak-valley capacity. The development of green new energy is restricted, and traditional flat photovoltaic panels can only work effectively at specific angles.

[0003] The performance of traditional solar panels is affected by the position of the sun. The highest power generation efficiency can only be achieved when the sun is directly shining, and sunlight can only be received in one direction. The design of traditional solar panels needs to consider the optimal orientation and tilt angle. At the same time, they are affected by dust, wind, sand, wind and rain, sunrise and sunset timing, and fiber optic line transmission, which may lead to inefficient space utilization and reduced power generation efficiency. Therefore, there is a problem of inconvenience in collecting solar energy in multiple directions and low-light power generation.

[0004] To this end, the present invention proposes a spherical high-efficiency photovoltaic power generation device. Summary of the invention

[0015] By adopting the above technical solution, the central ball has good light scattering properties and can guide light to the surface of the photovoltaic module to achieve optimal power generation efficiency.

[0017] By adopting the above technical solution, not only can the light energy on the outer surface of the connection frame be used to generate electricity through the first power generation silicon wafer and the second power generation silicon wafer, but also external input light sources, light sources of different frequency bands and micro-light inside the connection frame can be used to generate electricity after being concentrated, thereby forming a spherical high-efficiency photovoltaic power generation device based on the inner and outer surfaces.

[0019] As another preferred solution of the spherical high-efficiency photovoltaic power generation device of the present invention, a plurality of hollow reflective balls are arranged in the connecting frame.

[0020] By adopting the above technical scheme, the efficiency of power generation is increased by using the first power generation silicon wafer and the second power generation silicon wafer. At the same time, the first power generation silicon wafer and the second power generation silicon wafer are arranged in a football petal manner for installation, which facilitates the maintenance and replacement of power generation components for a group of damaged first power generation silicon wafers or second power generation silicon wafers. The components are in parallel mode, which reduces the failure rate and increases the operating time of the power generation equipment.
