Description

A photovoltaic power generation panel fixing frame

technical field

The utility model relates to the technical field of photovoltaic power generation, in particular to a photovoltaic power generation board fixing frame.

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.

In addition to the power generation power of photovoltaic panels being restricted by weather conditions, photovoltaic panels are placed outdoors for a long time, and there are inevitably dust, rain marks, bird droppings and other pollutants on the surface. These deposits will seriously affect the light transmittance of photovoltaic panels, resulting in photovoltaic panels The utilization rate of panels decreases, which greatly reduces the economic benefits of photovoltaic power generation.

Moreover, long-term exposure to rain and dew will also cause a certain degree of damage to the surface of the photovoltaic panel. Due to the acidity and alkalinity of rainwater, it will also corrode the glass cover, which will cause irreversible damage to the photovoltaic panel and reduce the conversion efficiency of the photovoltaic module 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 a lot of 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 water, snow, dust and other pollutants 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.
