Abstract
Description
Technical Field
[0001] The invention relates to the technical field of special cleaning tools for photovoltaic power stations, and in particular to a photovoltaic component bird droppings quick cleaning device. Background Art
[0002] As a green energy, solar energy is widely used in various fields due to its advantages such as never-failing, environmentally friendly and safe, and no geographical restrictions. In the actual application of solar photovoltaic power generation, photovoltaic modules are the most important unit for power generation, and their output power is directly affected by the intensity of sunlight. When sand, dust, snow, etc. fall on the surface of photovoltaic modules, the light transmittance is reduced, resulting in a significant reduction in photoelectric conversion efficiency. Therefore, in order to maintain the power generation efficiency of photovoltaic power stations, it is very important to clean the photovoltaic modules of photovoltaic power stations. The cleaning of photovoltaic modules in photovoltaic power stations has become an indispensable key link in the construction of photovoltaic power stations.
[0003] As the ecological environment improves, the number of birds increases, the range of bird activities expands, and the number of guano-contaminated components in photovoltaic power stations is increasing year by year. According to preliminary statistics from Huaneng Photovoltaic Power Station in Ningxia, guano-contaminated components account for about one thousandth of the total number of components. Bird droppings attached to the surface of photovoltaic power station components are the main factor causing component hot spot effects, component damage and system power generation losses. According to preliminary statistics from power stations, among the components that have been found to have hot spots, guano factors account for about two-thirds of the total number of hot spot components; the average annual power loss caused by bird droppings accounts for more than 3% of the theoretical power generation of the power station.
[0004] Local stains formed by bird droppings are a difficult point in component cleaning. Currently, photovoltaic components are cleaned by water trucks and robots, but the cleaning of bird droppings on components is not ideal.
