Products Description

BGT 50-100% RS485 Output 12-24V Supply Solar Panels Dust Monitoring System for PV station

The pollutants on the glass of solar modules are one of the main problems that rapidly affect photovoltaic power plants, which will reduce the efficiency and cost performance of power generation. In recent years, the production cost of photovoltaic modules has dropped significantly and the national industrial policy support has made photovoltaic power generation rapidly become the most potential new energy industry.The power generation efficiency of solar modules is affected by the ambient temperature, light intensity, the way cells are connected to cells, and dust. Dust has a greater impact on battery components. During the operation of the solar photovoltaic power generation system, it will be affected by the dust in its environment.The photoelectric conversion efficiency of photovoltaic cells is related to the intensity of solar radiation, dust accumulation on the surface of photovoltaic panels, will make the front cover glass transmittance decline, the decline in transmittance will lead to the decline in the output performance of the battery, the greater the deposition concentration, the lower the transmittance, the lower the amount of radiation absorbed by the panel, the greater the decline in output performance. Dust is particulate matter, and its sources are divided into natural sources and man-made sources. Including: soil, sand and rock under the action of the wind formed fine particles and some plant and animal biomass. When dust unevenly covers the surface of the PV module, the output U-P characteristic curve of the PV module presents a multi-peak characteristic curve, which will greatly affect the position of the maximum power point. In addition, because the dust absorbs solar radiation, the photovoltaic panel can be heated up, and the dust contains some corrosive chemical components, which also reduces its photoelectric conversion efficiency. Therefore, regular cleaning and maintenance of solar cell modules is an effective way to rapidly improve the power generation efficiency of photovoltaic power stations. By measuring the proportion of pollutants (SR), this translates into a loss of power generation in real time. This allows operations personnel to know when the contaminant has reached a critical point and it has become necessary to begin the cleaning process. The operation and maintenance personnel of the power station no longer need to pass the experience and visual inspection, and can scientifically and accurately choose the best cleaning plan, thus avoiding the loss of power generation efficiency and the waste of cleaning costs. Effectively improve the income of power station.

 

Application

Dust sensors are mainly used in photovoltaic arrays in solar farms, mounted on the frame of photovoltaic panels. By continuously measuring the transmission loss caused by pollutants on the glass, the reduction in sunlight reaching the solar module is calculated.
