Product Introduction

The DustCom Photovoltaic Power Station Dust Index Meter is an intelligent device specifically used to monitor the degree of surface pollution of photovoltaic panels. Its core function is to evaluate the impact of dust pollution on the power generation efficiency of photovoltaic modules.

By comparing the electrical performance parameters of clean modules and naturally dusted modules, it monitors the energy efficiency loss caused by pollution in real time, helping power stations to make photovoltaic operation and maintenance decisions and photovoltaic panel cleaning management.

The device is widely used in various ground photovoltaic power stations, distributed photovoltaic systems and new energy operation and maintenance platforms, and is an important part of the smart photovoltaic system.

Functional Features | Photovoltaic Panel Pollution Monitoring Solution

Working principle | SLI dust pollution index calculation method

The DustCom photovoltaic dust index meter uses the "reference module comparison method" as the core algorithm principle:

Two modules of the same model are deployed in the same photovoltaic power station environment, one is kept clean and the other is naturally dusted. By measuring the short-circuit current (Isc) and back temperature of the two, the effective irradiance (Geff) is calculated according to the IEC 60904 standard, and the pollution loss index (SLI) is further obtained:

SLI = (1 - Geffs / Geffc) × 100%

Geffs is the effective irradiance of the polluted module, and Geffc is the effective irradiance of the clean module.

The index can be used as a quantitative indicator of the degree of pollution of photovoltaic panels, providing data basis for the cleaning cycle arrangement, operation and maintenance cost control, and power generation efficiency guarantee of photovoltaic power stations.
