Explanation of Models Used in Photovoltaic Field Environmental Monitoring with Photovoltaic Weather Stations

In the field of renewable energy, the stable operation and efficient power generation of photovoltaic (PV) power plants rely heavily on meteorological data support. As the "weather brain" of PV power plants, the selection of meteorological monitoring equipment directly impacts power generation forecasting, equipment maintenance, and the economic benefits of the plant. Among various meteorological monitoring solutions, the TWS-4B PV Weather Station, introduced by Dongguan Lvguang New Energy, is becoming a preferred solution in the industry due to its professional performance and innovative design.

The TWS-4B PV Weather Station is a comprehensive environmental monitoring system specifically designed for PV power plants. The system adopts a modular design, integrating eight core monitoring modules: total radiation sensor, diffuse radiation sensor, direct radiation sensor, ambient temperature sensor, module temperature sensor, wind speed sensor, wind direction sensor, and precipitation sensor. This comprehensive data collection capability enables plant operators to grasp various environmental parameters affecting PV power generation efficiency. Among these, the total radiation sensor has a measurement range of 0-2000 W/m² with an accuracy of ±2%, accurately recording changes in solar radiation intensity. The module temperature sensor features a patch design with a measurement range of -40°C to +120°C, helping maintenance personnel monitor the operating temperature of PV panels in real-time, providing a basis for cleaning cycles and heat dissipation management.

Compared to traditional weather stations, the TWS-4B has significant advantages in data collection frequency. The device supports data collection at least once per minute and can be adjusted to higher frequencies as needed, ensuring the capture of instantaneous meteorological changes such as sudden light intensity fluctuations and gusts. The collected data is uploaded in real-time to a cloud monitoring platform via 4G wireless transmission technology. Combined with Lvguang New Energy's self-developed data analysis software, it enables advanced functions such as power generation forecasting, equipment anomaly alerts, and energy efficiency analysis.

In terms of environmental adaptability, the TWS-4B performs excellently. The device has an overall protection rating of IP65, with key sensors designed to be dustproof and waterproof, capable of withstanding harsh environments such as sandstorms and salt spray. The wind speed sensor uses ultrasonic principles with no mechanical rotating parts, avoiding the wear issues of traditional cup anemometers in sandy environments. Within an extreme temperature range of -30°C to 70°C, the device maintains stable operation, making it particularly suitable for the complex climatic conditions in PV-intensive regions such as Northwest and North China. According to the operational report of a 200MW PV power plant in Inner Mongolia, the TWS-4B maintained accurate data collection and 100% device integrity after 15 consecutive days of sandstorms.

Ease of installation is another highlight of the TWS-4B. The device adopts an integrated design, with all sensors mounted on a lightweight bracket. On-site installation takes only 2-3 hours, significantly shortening the plant construction cycle. The bracket is made of anodized aluminum alloy, which is lightweight yet high-strength, with wind resistance up to 60 m/s. A unique solar tracking system ensures that the radiation sensors always face the sun directly, eliminating the need for frequent manual angle adjustments. Engineers from a distributed PV project in Shandong reported that the TWS-4B reduced installation and debugging time by 40% compared to similar products, with data drift less than 1% within six months after initial calibration, significantly lowering maintenance costs.

In terms of data security and system compatibility, the TWS-4B uses industrial-grade encrypted transmission protocols to ensure meteorological data is not tampered with during transmission. The device supports multiple communication protocols such as Modbus RTU/TCP and HTTP, enabling seamless integration with plant management systems like SCADA and EMS. Open API interfaces allow third-party platforms to access data, meeting the customized needs of different clients.

From an economic perspective, the TWS-4B offers a competitive return on investment. Although the unit price is about 15% higher than that of ordinary weather stations, the more accurate data support enables more scientific operational decisions. Practical cases show that optimizing cleaning schedules based on module temperature data provided by the TWS-4B can reduce annual cleaning frequency by 2-3 times, saving maintenance costs by 80,000 to 120,000 RMB per MW. Utilizing its radiation data to optimize inverter parameters can improve power generation efficiency by 1.5-3%. Over a 20-year lifecycle, a single TWS-4B unit can generate over 20 million RMB in additional revenue for a 100MW power plant.

Dongguan Lvguang New Energy provides comprehensive technical support for the TWS-4B, including on-site installation guidance, regular calibration services, and data analysis training. The company has established a nationwide service network, promising a 24-hour response to故障 reports and on-site resolution within 72 hours. The device comes with a 5-year warranty, far exceeding the industry average of 3 years, reflecting the company's confidence in product quality. The manager of a PV power plant in Xinjiang commented: "Lvguang's technical team not only installed the equipment professionally but also regularly followed up to guide us on data analysis methods. This end-to-end service gives us great peace of mind."

As the PV industry moves toward智能化, the TWS-4B is continuously being upgraded. The new firmware already supports 5G transmission and edge computing capabilities, allowing preliminary data processing at the device end to reduce server load. The next-generation product will integrate atmospheric turbidity monitoring and snow detection modules to further meet the needs of power plants in特殊 environments.

In summary, the TWS-4B PV Weather Station, with its accurate monitoring, stability, reliability, and intelligent efficiency, provides a professional-grade meteorological data solution for PV power plants. Whether for large-scale ground-mounted plants or distributed projects, this device can effectively enhance plant management levels, optimize power generation efficiency, and improve return on investment. Against the backdrop of carbon neutrality goals driving the rapid development of the PV industry, choosing professional monitoring equipment like the TWS-4B will be a wise decision for plant operators to enhance their competitiveness.
