Description

technical field [0001] The invention belongs to the technical field of maintenance of photovoltaic power generation equipment, and in particular relates to a method and device for detecting and alarming the cleanliness of a photovoltaic panel. Background technique [0002] Solar energy is a new type of renewable energy, which is inexhaustible. Solar power generation does not produce waste and has no impact on the environment. Therefore, photovoltaic power generation has developed rapidly in recent years. In photovoltaic power generation, how to solve the detection of the cleanliness of photovoltaic panels is still a problem. The cleanliness of the surface of the photovoltaic power generation panel is not enough. If it is not cleaned in time, it will seriously affect the power generation efficiency of the photovoltaic power plant. It is very important; taking a 100,000-kilowatt photovoltaic power station as an example, the annual power generation is 160 million kWh. Because ...

Problems solved by technology

The cleanliness of the surface of the photovoltaic power generation panel is not enough. If it is not cleaned in time, it will seriously affect the power generation efficiency of the photovoltaic power plant. It is very important; taking a 100,000-kilowatt photovoltaic power station as an example, the annual power generation is 160 million kWh, because dust affects 5% of the power generation, and it will lose 8 million kWh of electricity a year, equivalent to an economic loss of 2.8 million yuan

For this reason, the cleaning of photovoltaic panels is of great significance, but when it needs to be cleaned, the existing detection technology for the cleanliness of photovoltaic panels mainly relies on manual inspection. This detection method is time-consuming and laborious, and the general photovoltaic power plant covers a relatively large area , generally in thousands of acres of land, so it is very inconvenient to rely on manual inspection, and the traditional manual inspection relies on naked eye recognition, and the quality of inspection is not high; so it is urgent to invent a photovoltaic panel cleanliness detection and alarm device to improve this. status quo
