Abstract

The invention discloses an inclination angle adjusting method and device of a flexible photovoltaic support, equipment and a storage medium, and relates to the technical field of photovoltaics, and the method utilizes the characteristic that the inclination angle of a photovoltaic panel of the flexible photovoltaic support can be adjusted by winding and unwinding an upper string cable and a lower string cable. By analyzing the linear relationship between the lengths of the upper and lower string cables of the flexible photovoltaic bracket and the inclination angle of the photovoltaic panel, the relationship between the retraction length change behavior and the inclination angle change behavior is determined, and a quantitative basis is provided for subsequently adjusting the inclination angle according to the solar radiation distribution. A solar high-radiation habit area is defined according to extreme value distribution in solar radiation distribution, and the inclination angle is adjusted according to the distance between the photovoltaic panel and the center of the solar high-radiation habit area, so that the farther the photovoltaic panel is away from the radiation center, the larger the inclination angle is, and the panel surface of the photovoltaic panel can face the radiation center in a larger area. Therefore, the light receiving efficiency is improved. The invention provides an inclination angle adjusting mode which is unique in standard, can be quantified and is relatively accurate.
