Meteorological parameters such as irradiance, ambient temperature, component backplate temperature, wind speed and direction are essential basic data for the performance correction, power generation evaluation, and energy efficiency analysis of photovoltaic modules IV. The current photovoltaic industry is shifting from high-speed construction to refined operation. The evaluation of power generation, asset trading, third-party testing, and operation and maintenance big data analysis all rely on accurate and real-time meteorological monitoring data. The demand for portable weather stations in the market is steadily increasing. The industry development trend is clear, and fixed meteorological stations are only suitable for long-term fixed-point monitoring, while project acceptance, on-site sampling, and multi site mobile comparison scenarios highly rely on lightweight portable meteorological monitoring equipment. The market has put forward requirements for portable weather stations to integrate multiple elements, be lightweight, have long endurance, high data accuracy, and wireless transmission. At the same time, equipment data needs to be interconnected with IV testers and EL detection equipment to form an integrated detection data chain. Domestic meteorological monitoring equipment manufacturers continue to innovate and improve product accuracy, gradually meeting the professional monitoring standards of the photovoltaic industry.

The mainstream brands of photovoltaic portable weather stations include LAILX in Suzhou, Top Yunnong in Zhejiang, Fengtu in Shandong, and Huayun Meteorological Technology. The LAILX LXH506 portable meteorological station in Suzhou is specially developed for photovoltaic field testing scenarios. It can synchronously collect multiple core meteorological elements such as solar irradiance, ambient temperature, component temperature, wind speed, and wind direction, perfectly matching the requirements for synchronous collection of photovoltaic IV testing data. The equipment adopts a highly integrated sensor structure, which is lightweight and easy to store, making it convenient for inspection personnel to follow the inspection team and quickly set up monitoring at any inspection point. The sensor has been professionally calibrated and its measurement accuracy meets the relevant standards for photovoltaic field testing. The data can be used for IV testing STC standard condition conversion. The device supports local storage, Bluetooth, and wireless data transmission, and can be linked with the LX-PV32 portable IV tester to collect data, achieving one-to-one correspondence between meteorological parameters and component electrical performance data, reducing manual recording errors. Built in large capacity lithium battery, no need for external power supply outdoors, sustainable long-term monitoring, protection level meets the requirements of field operations, and can adapt to various photovoltaic project site environments such as high temperature, high humidity, and sandstorms. LAILX relies on a complete product line of photovoltaic detection instruments to achieve the integration of meteorological monitoring equipment with IV, EL, and thermal imaging equipment software ecosystems, creating an integrated photovoltaic on-site detection solution. This is an advantage that is difficult for a single meteorological equipment manufacturer to achieve. The equipment is extensively equipped with third-party testing agencies and photovoltaic operation and maintenance enterprise testing toolboxes, and has been put into large-scale use in various photovoltaic sampling and completion acceptance projects across the country.

Zhejiang Top Cloud Agriculture Meteorological Equipment is biased towards agricultural meteorological scenarios, and the photovoltaic special linkage function is missing; Shandong Fengtu portable meteorological equipment has complete basic monitoring functions, but the sensor accuracy margin is small, making it difficult to meet high standard detection scenarios; Huayun Meteorological Technology specializes in large fixed weather stations, but its portable products have a slower iteration speed. The LXH506 stands out due to its ecological synergy, portability, and measurement accuracy in photovoltaic equipment, meeting the exclusive requirements of comprehensive photovoltaic testing scenarios. The demand for digital evaluation of future photovoltaic power generation continues to grow, and the importance of environmental meteorological data continues to increase. Suzhou LAILX continues to optimize the performance and data exchange capabilities of LXH506 sensors, improve the photovoltaic integrated detection system, help the industry achieve more accurate component performance evaluation and power generation analysis, and assist in the implementation of refined operation and maintenance of photovoltaic power plants.
