Solar module cleaning method

Abstract

The invention proposes a solar module cleaning method. When a pressure detected by a pressure sensor is detected to be greater than a set value, the method carries out automatic cleaning. The cleaning comprises the steps: turning a solar module, and enabling the front surface of the solar module to face downwards; carrying out vibration and blowing, thereby clearing away most of sands on the surface of the solar module; turning the solar module back after cleaning; detecting the pressure again: if the pressure value is less than the set value, it indicates that the cleaning is successful, or else, it indicates that there is a block, which is difficult to clear away, on the surface of the solar module, and transmitting information to a server if the block cannot be cleaned through vibration and blowing. The method can clean the surface of the solar module in a full-automatic manner, is high in intelligentization degree, does not need one-be-by manual inspection, greatly reduces the manpower and material resources, and is especially suitable for a large-scale solar power station.

Description

technical field [0001] The invention relates to the technical field of solar power generation, in particular to a solar module cleaning method used in a solar power station. Background technique [0002] At present, the solar power stations that have been used are mostly built in areas with abundant sunlight such as deserts and Gobi, and there are a lot of solar modules in a solar power station. These areas often have relatively large wind and sand, and the surface of solar modules is also easily covered by wind and sand. , and if the surface of the solar module is covered by wind and sand, it will greatly affect the power generation efficiency. Therefore, if the surface of the solar module is covered by sand, it needs to be cleaned in time. However, since there are a lot of solar modules in a solar power station, one by one Ground cleaning needs to waste a lot of manpower and material resources. If regular automatic cleaning is used, sometimes cleaning when it is not needed...

[0002] At present, most of the solar power stations that have been used are built in areas with abundant sunlight such as deserts and Gobi, and there are a lot of solar modules in a solar power station. These areas often have relatively large wind and sand, and the surface of solar modules is also easily covered by wind and sand. , and if the surface of the solar module is covered by wind and sand, it will greatly affect the power generation efficiency. Therefore, if the surface of the solar module is covered by sand, it needs to be cleaned in time. However, since there are a lot of solar modules in a solar power station, one by one Floor cleaning needs to waste a lot of manpower and material resources. If regular automatic cleaning is used, sometimes cleaning when it is not needed will often cause waste
