A tracking method and controller for double-sided photovoltaic cell modules based on intelligent control

Abstract

The invention discloses a tracking method and a controller for a double-sided photovoltaic cell assembly based on intelligent control. The tracking method calculates the maximum light intensity receiving angle value within a period of a light intensity sensor, and adjusts the angle and the maximum light intensity of the double-sided photovoltaic cell assembly. The light intensity receiving angle value is the same. The invention solves the loss of power generation caused by a series of environmental factors such as the different terrain of the installation site, the occlusion of the bracket, the background color, and the passing of objects of the double-sided photovoltaic cell module. Based on the real-time measurement of the sensor and the real-time control of the controller, the present invention gives full play to the greatest advantages of high conversion efficiency and high power generation of the double-sided photovoltaic cell.

Description

technical field [0001] The invention relates to the technical field of photovoltaic power generation, in particular to a tracking method and controller for double-sided photovoltaic cell components based on intelligent control. Background technique [0002] A photovoltaic system usually consists of many photovoltaic modules connected in series and parallel to form a photovoltaic array. Through the photoelectric conversion effect, the solar energy is converted into DC power, which is then converted into AC power by an inverter, and finally incorporated into the grid. At present, conventional photovoltaic modules are usually used on the side of the photovoltaic array, that is, photovoltaic cells are arranged on the front of the module, which can convert light into electricity. In the case of increasingly intensified contradictions between supply and demand of resources, the further development and utilization of solar energy will surely become a future development trend.

Problems solved by technology

[0005] (1) Since the angle of the sun's incident light is constantly changing, the double-sided battery module is only fixed vertically, and the maximum energy of the sun's light cannot be fully obtained in this direction, which will inevitably cause a certain amount of power loss;

[0006] (2) When the double-sided battery module receives reflected sunlight, its design structure determines that the light irradiation received by the module at the root is inconsistent with that at the top. The long-term unbalanced light irradiation of the double-sided battery module will lead to a decrease in its life. ;

[0007] (3) The load of the tracking bracket has been increased while adding the reflector. Further, the "V" shaped reflector is also a kind of joyride structure. In the case of strong wind, the main structure is extremely easy to be damaged;

[0008] (4) It is impossible to detect the overall intensity of sunlight received by the front and back of the double-sided module, and it is impossible to adjust the inclination angle of the module according to the sun's orbit to achieve the maximum power generation, which will inevitably cause a loss of power generation of the double-sided module

[0009] In summary, it is difficult for this utility model to be widely used in the market
