Description

technical field [0001] The invention belongs to the technical field of sensors, and relates to a solar tracking system for distributed sensing photovoltaic panels. Background technique [0002] Solar energy is a green energy that is valued at present. Various solar energy collection technologies and equipment are being put into use more and more. The utilization rate of solar energy of a solar device usually adopts a sensor to sense sunlight in solar light tracking technology. [0003] At present, most of the existing sensor sensing systems adopt single-board tracking, that is, sensors are installed on each photovoltaic board, and detection devices made of photosensitive materials are fixed around the sensors. The change can obtain the information of the light change. The sensor is fixed on the solar light receiving device and transmitted to the data processor in time, so as to obtain the error information of the solar tracking system, and cooperate with the appropriate con...

Problems solved by technology

[0004] On the one hand, after all, the sensor is only a small sensing unit in the photovoltaic power generation system, and the existing sensing system will use more sensors due to the increase in the number of photovoltaic panels, which will become too complex, large in number, and space-consuming

At the same time, there will be problems such as troublesome manufacturing and assembly and high cost in distributed photovoltaic power plants. It is even more difficult to assemble and not easy to maintain later in places where the geographical location is not flat.

[0005] On the other hand, the light harvesting range of existing sensors is limited, and there is a dead angle of light harvesting. The detection devices distributed around the sensor make the detection data different when receiving the sensing light, and at the same time, the accurate light direction and direct point cannot be obtained. The output accuracy is not enough
