The DustCom Dust Index Meter is a method that quantifies the impact of dust contamination on power generation efficiency by comparing the electrical performance parameters (such as short-circuit current and maximum power) of clean photovoltaic modules and dust-contaminated modules. Its core principle involves measuring the differences in electrical performance between clean and contaminated modules under identical conditions to calculate the efficiency loss caused by dust contamination, thereby providing data support for the operation and maintenance of photovoltaic power plants.
The photovoltaic dust monitoring system is compatible with PV panels rated up to 30A, 50V, and 700W. The included surface-mount Pt100 RTD is used to measure the temperature on the back of the PV panel, and data is transmitted via Modbus RTU (RS485).
Measurement Principle photovoltaic soiling sensor
The main principle behind the reference method for measuring photovoltaic module contamination is as follows: two photovoltaic modules of the same model and batch are placed in the same environment; one is kept clean, while the other is allowed to accumulate dust naturally. According to IEC 60904, the effective irradiance is calculated by measuring the short-circuit current and the temperature on the back of both modules. Contamination loss is determined by comparing the effective irradiance of the contaminated module with that of the clean reference module
.
The formula for calculating the Soiling Loss Index (SLI) is as follows:
SLI = (1 – Geffs/Geffc) × 100%. Here, Geffs is the effective irradiance calculated for the soiled module, and Geffc is the effective irradiance calculated for the clean reference module.
