Description

technical field [0001] The invention specifically relates to the field of photovoltaic modules, in particular to a remote-controllable photovoltaic module cleaning matrix device. Background technique [0002] Because the natural environment and the surrounding environment will pollute the surface of the photovoltaic module, resulting in a reduction in the power generation efficiency of the system, it is necessary to clean part or all of the photovoltaic power generation project components from time to time. In order to ensure personal safety during module cleaning, improve the quality and efficiency of cleaning work, and prolong the service life of photovoltaic modules, the cleaning tools and methods of photovoltaic modules need continuous technological innovation and progress. [0003] Existing cleaning methods include manual dry cleaning or water cleaning, large-scale mechanical cleaning or robot cleaning, among which: [0004] Disadvantages of manual dry cleaning: Differ...

AI Technical Summary

Problems solved by technology

[0004] Disadvantages of manual dry cleaning: Different operators have different strengths and different pressures on the components, which will cause excessive deformation of the components and cause cracks in the cells. The effect of dry cleaning components is not good, often due to too much dust on the mop Some traces are left, causing a large area of ​​shadow occlusion;

[0005] Disadvantages of manual water washing: when the water pressure is too high on the photovoltaic modules, it will cause cracks in the cells, and we cannot control the changes in the water pressure of the operator's nozzles during the process, because the greater the water pressure, the better the cleaning speed and effect;

[0006] Disadvantages of large-scale machinery and robot cleaning: high site environment requirements, inconvenient for large-scale machinery to enter the site, difficult installation of robots, high maintenance and initial construction costs;
