For photovoltaic (PV) power generation systems operating for extended periods, dust accumulation on solar panels directly impacts power generation efficiency. Dust on the panel surface reflects, scatters, and absorbs solar radiation, significantly reducing solar transmittance and consequently decreasing the amount of solar radiation received by the panel, thus lowering the output power.

The ES-DC1 PV soiling dust monitoring system is primarily used in PV arrays within solar power plants, installed on the frame of the PV panels. This system monitors dust accumulation on the power plant surface in real time, providing a scientific basis for cleaning and maintenance through intelligent data analysis. Suitable for PV power plants of all sizes, whether large centralized or distributed, it effectively improves power generation efficiency and reduces operation and maintenance costs, making it an indispensable intelligent management tool for the PV industry.
