A self-adaptive photovoltaic support with intelligent light following and active wind sheltering functions

Abstract

The invention provides a self-adaptive photovoltaic support with intelligent light following and active wind sheltering functions. The self-adaptive photovoltaic support comprises a stand column, a controller, a photovoltaic panel supporting truss, a solar panel folding mechanism, a wind speed detection device, a solar azimuth angle light following device and a solar altitude angle light followingdevice. The stand column is fixed to the ground; the controller is connected to the upper portion of the stand column through a hoop; the solar azimuth angle light following device is connected withthe stand column through a flange; the solar azimuth angle light following device is also connected with the solar altitude angle light following device through a flange; the photovoltaic panel supporting truss is connected with the solar altitude angle light following device; the solar panel folding mechanism is installed on the photovoltaic panel supporting truss; and the wind speed detection device is arranged in the middle of the photovoltaic panel supporting truss. The self-adaptive photovoltaic support adopts photoelectric and program type intelligent light following strategies, so thatthe problem of accumulative errors existing in program type light following is solved, and the stability problem of photoelectric light following is solved; and the power generation efficiency of theself-adaptive photovoltaic support is greatly improved compared with that of a traditional fixed photovoltaic support.

Description

technical field [0001] The invention relates to the field of photovoltaics, and more specifically, to an adaptive photovoltaic support with functions of intelligent light tracking and active wind avoidance. Background technique [0002] At present, the photovoltaic support mostly adopts fixed photovoltaic support. This kind of support requires the calculation of the local optimal installation inclination in advance in combination with the local geographical environment, climate and other conditions at the beginning of the design. This calculation needs to refer to the local climate data over the years. According to the setting of the inclination angle, it can be divided into: the best inclination angle fixed type, the inclined roof fixed type and the inclination angle adjustable fixed type. [0003] The best inclination angle fixed method is to calculate the local best installation inclination angle first, and then all arrays are installed at this inclination angle, which is...
