Problems solved by technology

Because the influence of water stains on the panels after cleaning is often neglected in the traditional cleaning method with water, and the power generation power of the panels is also high when the light intensity is high. Seriously affect the total output of the panels during the period of maximum power generation; and when cleaning is performed during a period of low light intensity, although the power generation power of the panels is not high, the evaporation time of water stains will also be longer, which may cause overall damage. The impact of power generation is still large

Abstract

The invention relates to the technical field of artificial intelligence, in particular to a method and device for determining the optimal cleaning time of a photovoltaic cell based on artificial intelligence. The method comprises the following steps: obtaining an initial water stain area and an inclination angle on a photovoltaic cell panel; according to the initial water stain area, obtaining theresidual water stain area in a preset time period, the illumination intensity of the photovoltaic cell panel, the surface temperature of the cell panel, the wind load and the environment temperature;constructing a water stain evaporation time model by taking the residual water stain area, the illumination intensity, the inclination angle, the surface temperature of the cell panel and the wind load as independent variables; using a power model constructed by taking the wind load, the environment temperature and the residual water stain area as independent variables to obtain average power generation power; and judging a preset time period corresponding to the minimum loss power as the optimal cleaning time of the battery panel by comparing the average power generation power with the standard power generation power. According to the invention, the most appropriate time period can be selected as the guidance time of the washing cleaning mode according to the reduction of the influence of the washing cleaning process on the overall power generation power of the photovoltaic module.

Description

technical field [0001] The invention relates to the technical field of artificial intelligence, in particular to an artificial intelligence-based method and device for determining the optimal cleaning time of photovoltaic cells. Background technique [0002] Photovoltaic power generation is a way to mainly use solar energy to generate electricity. Therefore, improving the power generation efficiency of photovoltaic modules and reducing the operating costs of photovoltaic modules are the main means to promote the development of the photovoltaic industry. Although there are many cleaning methods for photovoltaic panels, the most widely used cleaning method with the lowest cost is washing with water. [0003] During the daily washing and maintenance of photovoltaic panels, large areas of water stains are often left. The shading formed by these water stains will not only reduce the power generation efficiency of the modules, but also cause hot spots on the panels after long-term...
