Solar panel array surface dust removal system and method

Abstract

A solar panel array surface dust removal system and a method belong to the technical field of solar photovoltaic power generation. The solar panel array surface dust removal system comprises a high-pressure water generating device, a delivery pipe, an adjusting mechanism, at least one jetting device and a moving trolley, high-pressure water generated by the high-pressure water generating device forms a high-pressure water flow jetting plane via the jetting devices, two comprehensive actions of impacting and shearing are produced for dust covered on surfaces of solar panel arrays, and accordingly the dust of the surfaces of the solar panel arrays is removed. The main steps of the method comprise that basic dust removal parameters are determined, parameters of the jetting devices are selected, overall arrangement of the jetting devices is determined according to the sizes of the solar panel arrays, and a cleaning operation path is planned. The solar panel array surface dust removal system and the method are simple to be realized, are applicable to installation of most of solar panel arrays, save water, do not damage surfaces of solar panels, do not pollute environments, not only can realize a large-range high-efficient dust removal, but also have an auxiliary summer cooling function and a winter snow removal function.

Description

technical field [0001] The invention relates to a system and method for removing dirt and snow on the surface of a solar panel array, and belongs to the technical field of solar photovoltaic power generation. Background technique [0002] Due to its environmental protection and renewable advantages, photovoltaic power generation has been widely used and developed rapidly in recent years. Solar panels are one of the core components of the photovoltaic power generation system. Generally, they are connected in series and parallel to form a solar panel array, which is installed outdoors to receive sunlight and generate electricity. Its light receiving efficiency largely determines the photovoltaic power generation system. power generation efficiency. [0003] Large-scale solar photovoltaic power plants are often distributed in open deserts and sparsely populated areas such as Gobi. Solar panels are placed in bare environments and withstand severe tests such as wind, sand, frost...

AI Technical Summary

Problems solved by technology

[0004] 1) Manual dust removal is time-consuming and labor-intensive, with long intervals; and with the increase in labor costs, a large number of manual dust removal will lead to an increase in power generation costs;

[0005] 2) The existing dust removal system is mainly aimed at a single solar panel, and needs to be installed around the solar panel array or on its support, which has certain restrictions on the design and installation of the solar panel array, which is not conducive to later maintenance;

[0006] 3) Using friction dust removal, it is easy to generate static electricity, scratch the surface of solar panels, and the work efficiency is low, so it is not suitable for large-area solar panel arrays;

[0007] 4) High-pressure water guns are used for cleaning, which consumes a lot of water. It is not suitable for photovoltaic power stations in deserts or Gobi, and is not conducive to environmental protection.
