Automatic cleaning system and cleaning method for photovoltaic power station

Abstract

An automatic cleaning system and cleaning method for a photovoltaic power station for judging whether a solar panel in a photovoltaic power station should be cleaned according to a time parameter of arechargeable battery used by a cleaning robot are disclosed. The cleaning method adopts a simple criterion and the judgment result is accurate. The system comprises a solar cell panel, an intelligentcleaning system, an environmental information measuring unit, an external information source unit and a management control center. According to the operation data of the rechargeable batteries of each cleaning robot distributed in the photovoltaic power station, based on the environmental factors, the invention automatically deduces which factor is the cause of the power generation efficiency decrease of the photovoltaic system, automatically determines the time of clean photovoltaic power generation solar panels, and automatically generates and sends the recommendations of intelligent cleaning system management and control to the customers, so as to realize the centralized management and remote monitoring of the remote system of photovoltaic power station, which is unattended. The invention improves the energy production efficiency of the photovoltaic system and reduces the operation and maintenance cost.

Description

technical field [0001] The invention relates to a photovoltaic power station operation and maintenance system and operation and maintenance method, in particular to a system and method for automatically determining the cleaning time of a photovoltaic power station based on environmental factors that affect the efficiency of the photovoltaic system. Background technique [0002] The photovoltaic industry is a sunrise industry based on semiconductor technology and new energy demand, and will be the commanding heights of global advanced industry competition in the future. Photovoltaic system efficiency depends on the cleanliness of the surface of the solar panel. When there is a lot of dust and dirt accumulated on it, it will reduce its power generation efficiency. [0003] Most photovoltaic power plants are located in sunny desert areas with intensive solar radiation. However, due to the frequent occurrence of sandstorms, thick sand and dust are often accumulated on them. In o...

[0006] The disadvantage of this method is that it only depends on the amount of actual power generation to judge whether it should be cleared, ignoring the fact that the sensors used to collect solar radiation intensity and solar radiation are easy to accumulate dust (usually not cleaned frequently), resulting in the collected factors related to inaccurate data, and the method is not practical
