The invention discloses a solar cell assembly surface dust automatic monitoring system comprising sensors, a solar cell assembly, a power module, a detecting module, a processing module, an output module, and a driving module. The sensors are installed in the solar cell assembly and may accurately measure the intensity of light that can be actually received by a solar cell in the solar cell assembly. The dust accumulation degree on the surface of the solar cell assembly can be accurately determined by comparing the intensity of light with that measured by a sensor outside the solar cell assembly in real time, and by using a certain data processing algorithm. The solar cell assembly surface dust automatic monitoring system is high in accuracy, easy to implement, novel in determining method, and capable of achieving real-time monitoring, and has a certain market requirement in the solar cell assembly cleaning field. Used in an actual photovoltaic power generation system, the solar cell assembly surface dust automatic monitoring system may accurately give a cleaning occasion and further reduces the cleaning cost of the solar cell assembly.
Description
technical field [0001] The invention relates to the field of photovoltaic power generation, in particular to automatic monitoring of dust on the surface of solar panels. Background technique [0002] Photovoltaic power generation technology uses solar cells to convert solar energy into electrical energy, and the amount of light absorbed by solar cells is crucial to the conversion efficiency of photovoltaic power generation. In an actual photovoltaic power generation system, solar cells generally need to be packaged into modules. Solar cell components can also be called solar panels or photovoltaic components (in this text, they are all represented by solar cell components), because their power generation is very seriously affected by light, if the solar cell components accumulate a lot of dust, it will be greatly affected. Reduce the power generation of the photovoltaic system. In actual photovoltaic power generation, solar cell components are often exposed to the environm...
