Photovoltaic power plant dust monitoring equipment

Photovoltaic power plant dust monitoring equipmentImproving power generation efficiency by timely cleaning the dust on the surface of photovoltaic panels, reducing the obstruction of sunlight by dust, and increasing the transmittance of photovoltaic panels, thereby enhancing power generation efficiency. Experimental data shows that when the transmittance decreases by 5%, the power loss of typical photovoltaic modules can reach 3% to 5%. In areas with frequent sandstorms, the monthly power loss can even exceed 12%. Reduce operation and maintenance costs by accurately monitoring dust accumulation and avoiding water and manpower waste caused by excessive cleaning. The system supports docking with intelligent cleaning robots to achieve automated cleaning operations, further reducing operation and maintenance costs. Extending the service life of photovoltaic systems by timely cleaning the dust on the surface of photovoltaic panels can avoid serious problems such as "hot spot effect" caused by dust accumulation and prolong the service life of photovoltaic systems. In the long run, this will help power plants achieve higher power generation and more stable revenue.

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.

Photovoltaic power plant dust monitoring equipmentBy 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.
