Solar Panel Dust Monitoring System: Preventing Efficiency Loss from Dust Accumulation

Photovoltaic panels are installed in outdoor environments, and their surfaces are extremely prone to dust accumulation. The coverage of dust can greatly reduce the photoelectric conversion efficiency of photovoltaic panels, thus affecting power generation. Therefore, it is necessary to clean the dust in a timely manner with the help of manual or automated equipment. Currently, the judgment of the dust amount mostly relies on manual observation, lacks a unified standard, and is highly subjective. If cleaning is carried out when the dust amount is small, it will cause a waste of human and material resources; if there is too much dust, it will affect the power generation efficiency. Therefore, timely monitoring and cleaning can keep the panels in a highly efficient working state and ensure optimal power output.

The core functions of the Dust Monitoring System for Solar Panel are to monitor the dust accumulation on the surface of photovoltaic components in real - time and conduct data analysis. With the help of this system, power station managers can promptly understand the cleanliness of photovoltaic components and then take corresponding cleaning measures to avoid the adverse effects of dust accumulation on the power generation efficiency of photovoltaic power stations. For long - term operating photovoltaic power generation systems, the impact of panel dust accumulation cannot be underestimated. The dust on the panel surface can reflect, scatter, and absorb solar radiation, reducing the solar transmittance, resulting in a decrease in the solar radiation received by the panel and a consequent reduction in the output power.

The dust monitoring system can accurately detect the impact of dust on photovoltaic panels, issue timely warnings and take actions to prevent equipment failures caused by dust accumulation, and improve the stability and reliability of the system. This system detects the accumulation of dust and dirt through sensors installed on the surface of photovoltaic panels.
