By monitoring the accumulation of dust in real-time, it helps operation and maintenance personnel accurately evaluate the impact of dust accumulation on power generation efficiency and develop reasonable cleaning plans. High pollution areas such as deserts and arid regions accumulate dust quickly, making regular testing and cleaning particularly important. The dust accumulation detection system can monitor the accumulation of dust in real time, issue warning signals in a timely manner, and ensure that the photovoltaic panels are always in good cleaning condition.

1、 Product Overview
The pollutants on the glass of solar modules are one of the main issues that rapidly affect photovoltaic power plants, reducing power generation efficiency and cost-effectiveness. The use of blue light pollution closed loop measurement (OMBP) technology can easily be installed in new or existing photovoltaic arrays and integrated into power plant management systems. The device is installed on the frame of the photovoltaic panel. By continuously measuring the transmission loss caused by pollutants on the glass, the reduction in sunlight reaching the solar module can be calculated.
High precision dust monitoring system for photovoltaic power plantsBy measuring the proportion of pollutants (SR), it is converted into real-time loss of power generation. This allows operation and maintenance personnel to know when pollutants reach the critical point and when it is necessary to start the cleaning process. This product does not require maintenance and only needs to be cleaned in the same way when cleaning surrounding components.
Due to the varying pollution rates of large photovoltaic power plants throughout the entire park, the IEC 61724-1 standard requires multi-point measurement. Compared to traditional systems, it has much lower procurement, installation, and maintenance costs, making it more economical, so cleaning can be planned at the time and place needed.

6、 Equipment installation
Preparation before installation:
Dust monitoring system equipment, dust monitoring solar connector A * 4, dust monitoring solar connector B * 4, screw and nut M8 * 70 kit * 4.
Installation description:
This device needs to be installed in conjunction with the photovoltaic panel. After preparing for installation, the dust monitoring device should be placed parallel to the solar photovoltaic panel, with the glass surface facing the light receiving surface of the solar panel. The dust monitoring solar connector A should be placed in an inverted shape between the solar panel and the dust monitoring system device, and the dust monitoring solar connector B should be placed at the bottom of the device. Use M8 screws and nuts to penetrate and tighten, and repeat the steps to fix the installation at multiple points.
