Solar Dust Monitoring Instrument Successfully Exported to India

June 5, 2025 — Our independently developed Solar Dust Monitoring Instrument (Soiling Sensor) has been successfully exported to India, marking an important step for our company in the international photovoltaic market. This product, featuring innovative blue light pollutant optical closed-loop measurement technology, provides a solution to enhance the operational efficiency of photovoltaic power stations in India.

Application Scenarios of the Solar Dust Monitoring Instrument 

The Solar Dust Monitoring Instrument is widely used in both new and existing photovoltaic power stations, particularly in the following scenarios: 

Large-Scale Ground-Mounted Photovoltaic Power Stations: In high-dust environments like deserts and Gobi regions, it monitors the glass surface pollutants in real time and optimizes cleaning cycles.

Distributed Photovoltaic Systems: Suitable for rooftop photovoltaic projects, ensuring maximum power generation efficiency.

Remote Area Power Stations: Ideal for areas with limited maintenance resources and infrequent maintenance requirements.

Smart Power Station Management: Seamlessly integrated into power station management systems, providing data support and assisting in intelligent operation and maintenance.

Product Introduction of the Solar Dust Monitoring Instrument 

The Solar Dust Monitoring Instrument is an intelligent monitoring device designed specifically for photovoltaic power stations. It uses advanced blue light pollutant optical closed-loop measurement technology, installed on the photovoltaic panel frame. It continuously measures the contamination ratio (SR) of the glass surface and calculates in real time the reduction in sunlight reaching the solar components, accurately evaluating the power generation loss. This device helps maintenance personnel determine the optimal cleaning time, significantly improving the power station’s efficiency and cost-effectiveness.

Technical Highlights of the Solar Dust Monitoring Instrument 

High-Precision Measurement: The accuracy of pollution ratio measurement is ±1% within 90-100%, ±3% within 80-90%, and ±5% within 50-80%.

Seamless Integration: Supports RS485 signal output and standard MODBUS protocol, easily connecting to the power station management system.

Low Power Consumption: The average power consumption is only 1W, with a DC 12V supply voltage, making it energy-efficient and environmentally friendly.

Maintenance-Free: No additional maintenance required, just wipe the device when cleaning the photovoltaic components.

Optional Temperature Monitoring: Supports temperature measurement in the range of -50℃ to +100℃, with an accuracy of ±0.5℃ at 25℃.

The successful export of the Solar Dust Monitoring Instrument to India not only demonstrates our company’s technical strength in photovoltaic operation and maintenance but also contributes to the sustainable development of India’s renewable energy market. We look forward to collaborating with more international partners to promote the flourishing development of global clean energy.
