I. Hardware Design for Multi-Scenario Adaptation

The photovoltaic power plant weather station adopts a modular architecture design. Its core monitoring unit includes professional meteorological sensors such as a pyranometer, wind speed and direction sensor, temperature and humidity probe, and barometer. Notably, its pyranometer features secondary standard accuracy (compliant with ISO9060 specifications), with a spectral response range covering 280-3000 nm, accurately capturing direct solar radiation, diffuse radiation, and reflected radiation data, with measurement errors controlled within ±2%. To meet the needs of photovoltaic power plants of different scales, the device supports customizable expansion modules, such as adding module backplane temperature monitoring, rain and snow sensors, or dust accumulation monitors. This flexible configuration allows it to meet the monitoring requirements of large ground-mounted power plants as well as compact installation environments of distributed rooftop power plants.

In terms of environmental adaptability, the device demonstrates significant advantages. Its main structure is made of aviation-grade aluminum alloy with an anodized surface, capable of withstanding extreme temperatures from -40°C to 80°C. After three years of continuous operation at a wind farm in Inner Mongolia, key sensors maintained over 90% data accuracy. For high-salt-spray coastal areas, the manufacturer also offers a stainless steel anti-corrosion version, effectively addressing the corrosion issues traditional meteorological equipment faces in harsh environments.

II. Intelligent Data Management Platform

Unlike the single data acquisition function of traditional weather stations, the cloud platform accompanying the TWS-4B Photovoltaic Power Plant Weather Station enables in-depth application of monitoring data. The system updates real-time data every 5 seconds, transmitted via 4G/fiber dual channels, ensuring a data packet loss rate below 0.1%. The built-in AI algorithm automatically identifies abnormal data, such as sudden radiation drops due to cloud cover or equipment soiling, and promptly sends alerts.

More notably, its data modeling capability allows the system to automatically generate irradiance-power output curves and compare them with theoretical values, achieving an accuracy rate of up to 95%. This visual analysis tool provides an intuitive basis for power plant performance evaluation.

III. Industry Recognition and Market Feedback

As photovoltaic power plants enter the era of refined operation where "every kilowatt-hour counts," the TWS-4B Photovoltaic Power Plant Weather Station continues to evolve. From practical application results, the device has surpassed the role of traditional meteorological monitoring tools and gradually developed into the "meteorological brain" of photovoltaic power plants. Its value lies not only in the reliability of basic data acquisition but also in the improvement of power generation efficiency through data fusion and analysis. In the wave of digital transformation in the new energy sector, this product strategy, which deeply integrates hardware performance with software intelligence, may become the mainstream development direction in the field of photovoltaic meteorological monitoring.
