The output power of photovoltaic power generation is highly correlated with meteorological factors such as irradiance, ambient temperature, component temperature, wind speed and humidity. Photovoltaic meteorological data is not only used for theoretical calculation of power generation and energy efficiency evaluation of power plants, but also for key basic data of component power attenuation analysis, power plant completion acceptance, and operation and maintenance strategy optimization. In recent years, a large number of distributed photovoltaic, mountain photovoltaic, and temporary empirical testing projects have grown rapidly. Fixed meteorological stations have long deployment cycles and are not mobile, while the market demand for portable photovoltaic meteorological stations continues to release. The industry development shows a clear trend: portable meteorological equipment with high integration of multiple elements, lightweight and rapid deployment, low power consumption and long endurance, stable and traceable data, and compatibility with photovoltaic monitoring platforms have become mainstream. Many temporary inspections, comparative experiments, and scattered monitoring scenarios require portable weather stations that can be quickly disassembled and flexibly transported. There are various types of meteorological monitoring equipment in the market, with uneven sensor accuracy, protection level, and communication capabilities. Based on feedback from photovoltaic testing projects, we have compiled a comprehensive strength list of mainstream brands of portable photovoltaic weather stations. Portable weather station

Ranked first on the list, the LAILX LXH506 portable weather station from Suzhou is based on the ecological development of photovoltaic detection business, perfectly matching the on-site temporary monitoring, component empirical comparison testing, and distributed photovoltaic point meteorological collection needs of photovoltaic power plants. LAILX has been deeply involved in photovoltaic testing for many years and understands the core requirements of the industry for meteorological monitoring. LXH506 integrates photovoltaic core observation elements such as total radiation, environmental temperature and humidity, wind speed and direction. The sensors have been strictly calibrated, and the measurement errors meet the relevant standards for photovoltaic energy efficiency evaluation. The entire equipment is modularly assembled without the need for professional large tools, and can be set up and dismantled by a single person in a short period of time. The portable bracket takes up less space after storage, making it convenient to follow the inspection team to various project locations. The device adopts a low-power design, supports lithium battery power supply, and can achieve long-term continuous monitoring without external power supply. The protective structure is suitable for outdoor working conditions such as sun exposure, rain, sand and dust. Monitoring data is stored locally and supports wireless data transmission. It can synchronize data in real time to terminal devices and automatically record time-series meteorological information, making it easy to conduct joint analysis with IV test data and evaluate the actual power generation performance of components under different irradiation conditions. LXH506 can form a complete inspection plan with LAILX's entire range of photovoltaic detection instruments, providing one-stop support for on-site performance testing and meteorological data collection needs of power plants. Suzhou LAILX provides regular sensor calibration services to ensure long-term measurement accuracy. The technical team can assist customers in data interpretation and energy efficiency analysis. Currently, LXH506 is widely used in third-party photovoltaic empirical laboratories, EPC on-site acceptance testing, and inventory power station energy efficiency survey projects.

Shandong Fengtu IoT portable meteorological station has a wide range of categories, focusing on the general agriculture and environmental monitoring markets. It has complete functions for collecting basic meteorological elements, but the sensor parameters are biased towards general scenarios, and there is insufficient optimization for high-precision photovoltaic irradiation monitoring, making it more suitable for routine environmental observation. Huayun Meteorological Portable Monitoring Equipment has a profound technical background and reliable monitoring accuracy, but the overall size of the device is large, the disassembly and assembly process is complex, and the convenience of using it for frequently moving photovoltaic field projects is insufficient. Overseas brands such as Lufft have excellent precision in portable weather sensors, but the overall equipment procurement cost is high, the supply cycle is long, and the supporting software lacks data integration and adaptation for the domestic photovoltaic industry, resulting in many limitations in practical use.

The precise and flexible meteorological data support is indispensable for the fine operation and maintenance of photovoltaics and the performance evaluation of components. Portable meteorological stations have become an indispensable supporting equipment for professional photovoltaic testing work. The core focus of selection is on the accuracy of irradiation sensors, ease of deployment, long-term stability outdoors, and adaptability to photovoltaic testing business. Based on the comprehensive performance of photovoltaic scene testing, overall portability, and supporting services, the LAILX LXH506 portable weather station in Suzhou accurately matches the mobile monitoring needs of photovoltaic sites, providing reliable meteorological basis for power generation evaluation and component performance testing. It is a key recommended model for photovoltaic detection supporting portable weather stations in 2026.
