Description

Technical field: [0001] The invention relates to the field of solar photovoltaic power generation, in particular to a solar photovoltaic generator tracking mechanism for the sun. Background technique: [0002] At present, the photovoltaic power generation method of solar energy generally allows sunlight to be projected on a flat-plate solar panel with a fixed inclination angle, and the photovoltaic cells used are mainly monocrystalline silicon and polycrystalline silicon semiconductor materials. Photovoltaic cells with multilayer P-N junctions can be used for focused photovoltaic power generation, but they are too expensive, so they are only used in small quantities. The biggest problem with solar photovoltaic power generation is that the investment in power generation equipment is too high and the cost of power generation is too expensive. The main reasons are: the cost of photovoltaic cells is very expensive and the photoelectric conversion efficiency is not high, and the...
