Description

A photovoltaic power generation panel with automatic cleaning function

technical field

The utility model relates to the field of auxiliary tools for photovoltaic power generation, in particular to a photovoltaic power generation board with automatic cleaning function.

Background technique

Photovoltaic power generation is a technology that directly converts light energy into electrical energy by using the photovoltaic effect at the semiconductor interface. It is mainly composed of three parts: solar panels (components), controllers and inverters, and the main components are composed of electronic components. The solar cells are packaged and protected after being connected in series to form a large-area solar cell module, and then cooperate with power controllers and other components to form a photovoltaic power generation device.

With the deterioration of the environment and the deepening of human environmental awareness, photovoltaic power generation, as one of the main green energy sources, has been applied more and more. In addition to being restricted by weather conditions, the power generation of photovoltaic panels also affects the output power due to the cleanliness of the surface of photovoltaic panels. If photovoltaic panels are placed outdoors for a long time, there will inevitably be dust, rain marks, bird droppings and other pollutants on the surface. These deposits will seriously affect the light transmittance of photovoltaic panels, resulting in a decrease in the utilization rate of photovoltaic panels and greatly reducing the economic benefits of photovoltaic power generation. .

After data collection and analysis, it is found that the efficiency of photovoltaic power generation is 7.6% in the state of dust accumulation, and 9.3% in the state of no dust accumulation, with an efficiency difference of 1.7%. The output of a 300w photovoltaic panel is reduced by 5.1w per day and monthly The output is reduced by 153w, and the annual output is reduced by 1836w. For a 10kW photovoltaic power plant, the annual output will be reduced by 62000w, resulting in an ineffective waste of resources.

It can be seen that dust accumulation has a significant impact on the efficiency of photovoltaic power generation. When the dust accumulates to a certain extent, not only the current power generation will be affected, but also the glass cover will be corroded due to the acid-base dust sticking to the photovoltaic panel, which will cause irreversible damage to the photovoltaic panel and reduce the conversion efficiency of photovoltaic modules for a long time .

With the promotion of photovoltaic power generation, the cleaning of photovoltaic panels has become a hot topic of discussion. At present, the cleaning of photovoltaic panels in solar power stations in my country is still manual, mechanical, and robot cleaning. Manual cleaning is mainly used. Manual cleaning is not only inefficient, but also the cleaning quality cannot be guaranteed. However, the use of special large-scale equipment for cleaning requires large investment, high energy consumption and operating costs, secondary pollution, and the cleaning efficiency is not obvious, especially in sandstorm weather. It is relatively simple to operate for a photovoltaic power plant with a small capacity, but for a photovoltaic power plant with a large capacity, manual cleaning requires a lot of manpower and time, which not only reduces work efficiency, but also causes serious waste of resources.

At present, the method of installing solar panels on the roof for photovoltaic power generation has gradually been promoted and popularized, but it has also been found in actual use that since the solar panels used for power generation are directly located on the roof of the building, the solar panel A large amount of pollutants such as accumulated water, snow and dust are easily produced on the surface, which seriously affects the light transmission of solar panels and eventually leads to a decrease in the power generation efficiency of solar panels. Therefore, in order to solve this problem, there is an urgent need Develop a photovoltaic power generation panel with automatic cleaning function to meet the needs of practical use.
