Description

Much sand and dust carried by the wind will deposit on the surface of photovoltaic modules with the passage of time，which will affect the reflectivity and transmittance of the glass cover plate on photovoltaic modules, thus reducing the conversion efficiency of solar photovoltaic modules.

RK210-03B dust monitoring system perfectly solves the problem that the user is difficult to monitor the dust of solar panels. RK210-03B adopts blue light pollutant optical closed-loop measurement (OMBP) technology, measures and calculates the surface cleanliness, which shows that the cleanliness decreases all the way from 100% to 50%. It enables users to find a balance between power generation efficiency and cleaning cost. The operation and maintenance personnel of photovoltaic station can use scientific and accurate methods instead of selecting the best cleaning scheme through visual inspection. Thus, the loss of power generation efficiency and the waste of cleaning funds are avoided. Effectively improve the benefits of photovoltaic stations.

The dust monitoring system for a photovoltaic power station can be easily installed into a new or existing photovoltaic array and integrated into the power station management system. The device is mounted on the frame of photovoltaic panels and does not need sunlight to work. By continuously measuring the transmission losses caused by contaminants on the glass, the reduction in the amount of sunlight reaching the solar panel was calculated.
