Abstract

The invention provides a solar photovoltaic power generation system with high conversion efficiency. The system comprises a solar panel, a sunlight tracking module, a power storage and distribution module and a panel cleaning module, wherein the sunlight tracking module is used for adjusting the facing direction of the solar panel according to the sunlight direction of the position where the solar panel is located; a power output distribution module is used for judging a power output fluctuation coefficient of the solar panel and selecting a power output node according to a judgment result; and the panel cleaning module is used for calculating the power generation efficiency of the solar panel and cleaning the panel of the solar panel when the power generation efficiency is smaller than a preset lower limit threshold value. According to the invention, an excellent external environment coping scheme, an accurate automatic sun tracking system and an efficient power output scheme are provided, so that the conversion efficiency of solar photovoltaic power generation is improved.

Description

technical field [0001] The invention relates to the field of photovoltaic power generation panel control, in particular to a solar photovoltaic power generation system with high conversion efficiency. Background technique [0002] Solar panels mainly convert solar radiation energy into electrical energy directly or indirectly through photoelectric effect or photochemical effect by absorbing sunlight. That is to say, the more solar radiation the solar panel receives, the more electricity it can convert, so the output power of the solar module depends on factors such as solar irradiance and solar cell temperature. There are too many factors that affect power generation, such as surface temperature, light intensity, atmospheric permeability, external climate environment, seasons and other factors will affect solar power generation. [0003] A number of existing patents on improving the efficiency of solar photovoltaic power generation start from the material and structure of s...
