Abstract

The invention discloses a double-face photovoltaic battery assembly tracking method based on intelligentized control and a controller. The double-face photovoltaic battery assembly tracking method can calculate a maximum light intensity reception angle value in a cycle through a light intensity sensor and regulates the angle of the double-face photovoltaic battery assembly to be the same as the maximum light intensity reception angle value. The double-face photovoltaic battery assembly tracking method based on the intelligentized control and controller solve generating loss caused by a series of environment factors like different terrains, support shielding, background colors, object passage, etc. The double-face photovoltaic battery assembly tracking method based on intelligent control and the controller are based on real-time measurement of the sensor and based on real-time control of the controller and fully take advantages of high conversion efficiency of the double-face photovoltaic battery and big electricity generating amount.

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
