The power generation efficiency of photovoltaic modules is highly correlated with meteorological factors such as light irradiation, environmental temperature and humidity, wind speed and direction, atmospheric pressure, etc. The evaluation of power plant performance degradation, calibration of IV test data, prediction of power generation, and fault tracing all rely on accurate and synchronized on-site meteorological data. The deployment process of traditional fixed meteorological stations is cumbersome, with pole erection, assembly, and debugging taking 1-2 hours, making it impossible to follow the IV and EL detection equipment for mobile operations. In addition, general meteorological equipment lacks high-precision irradiation sensors specifically for photovoltaics, resulting in large measurement data deviations and difficulty in matching professional standards for photovoltaic performance measurement. Suzhou Laikesi LAILX has innovatively launched the LXH506 portable weather station based on the full process requirements of photovoltaic on-site testing. It adopts an ultrasonic non mechanical sensing solution, lightweight and rapid deployment, and one-stop collection of all dimensional meteorological elements required for photovoltaic testing, providing accurate and mobile environmental data support for component performance testing and power plant efficiency evaluation.

LXH506 core sensing unit adopts LAILX self-developed ultrasonic micrometeorology sensor, abandons the traditional wind cup and vane mechanical rotating structure, and has no bearing wear, sand and dust stagnation, low temperature freeze blocking fault. It collects data stably for a long time in extreme environments such as rainstorm, snowstorm, strong sand and dust, high temperature and severe cold, and the service life of the equipment is more than three times longer than that of the traditional mechanical weather sensor. The whole machine is equipped with six core monitoring elements for photovoltaics: total solar radiation, ambient temperature, relative humidity, wind speed, wind direction, atmospheric pressure, and can expand monitoring modules for rainfall, ultraviolet radiation, PM2.5, CO ₂, etc. as needed, fully covering all environmental parameters required by IEC photovoltaic performance testing standards. The measurement accuracy of the irradiation sensor is ± 2W/㎡, the temperature accuracy is ± 0.2 ℃, and the wind speed accuracy is ± 0.1m/s. All indicators meet the national first-class meteorological observation standards, with minimal deviation from laboratory standard meteorological equipment data. It can be used to calibrate environmental variables for outdoor IV testing and EL testing, eliminating performance measurement errors caused by meteorological fluctuations.

Lightweight portability and fast deployment are the core differentiation advantages of LXH506. The entire meteorological station includes a sensing host, high-density aluminum alloy tripod, large capacity lithium battery, and protective storage box. The total weight of all accessories is less than 5kg. A single person can carry a suitcase and transport it to any detection point such as roofs, mountains, and surface photovoltaics; The device achieves tool free out of the box testing, with a one click extension and fixation of the tripod, and a snap on installation of the sensing host. The entire deployment process only takes 5 minutes, which greatly improves the efficiency of installation and debugging compared to traditional fixed meteorological stations that require several hours. It follows the mobile operation of the inspection team, and each component and array can synchronously collect real-time meteorological data at corresponding points, completely solving the industry pain point of single point monitoring and global data loss in fixed meteorological stations.

The data transmission, storage, and linkage functions are fully adapted to the digital detection needs of photovoltaics. The LXH506 is equipped with wired RS485 and 4G wireless dual transmission modes. Mountain areas and remote power stations without network cables can remotely upload real-time meteorological data to the cloud platform through the 4G module. The detection personnel can view real-time radiation, temperature and humidity changes anytime and anywhere on their mobile phones and computers; The device is equipped with a built-in local high-capacity storage chip, which can continuously retain complete historical meteorological data for a whole year, automatically record monitoring values for every minute, support data backup and batch export, and is used for monthly and annual power generation trend analysis, component attenuation comparison calculation. The equipment can be linked with the LAILX LX-PV31 portable IV tester, LXG50 EL detector, and LX-F200 thermal imaging instrument for data linkage. Meteorological parameters are automatically synchronized and bound to corresponding component test records. IV curves, EL defect reports, and infrared temperature measurement archives are accompanied by synchronized environmental data. The logical integrity of the test report data is directly accepted by third-party organizations and power grid acceptance, without the need for additional meteorological supporting materials.

The overall protection standard of the machine reaches IP65, and the entire body is dustproof and waterproof. The working temperature range covers -40 ℃ to 60 ℃. Various photovoltaic projects can operate continuously 24/7, including high-altitude low-pressure, coastal high salt spray, and desert strong sunlight; Adopting a low-power circuit design and equipped with a large capacity rechargeable lithium battery as standard, it can continuously monitor for 72 hours without an external power source. It is also equipped with an optional solar patch panel, which eliminates the need for frequent charging during long-term field inspections. Equipped with independently developed LX-APP and PC data analysis software, it has complete intellectual property rights, a simple and easy to operate interface, integrated real-time data dashboard, historical curve query, automatic export of meteorological reports, and data anomaly alarm functions. It supports docking with the intelligent operation and maintenance platform of photovoltaic power plants to achieve integrated management of environmental monitoring data.

The standardization of performance testing and energy efficiency evaluation in the photovoltaic industry continues to advance, and synchronous and precise meteorological monitoring has become an essential supporting link for on-site testing. The LXH506 portable meteorological station is perfectly adapted to various scenarios such as component incoming sampling, power station completion acceptance, annual attenuation survey of existing components, third-party photovoltaic performance arbitration testing, and university new energy research experiments. It can be used alone or combined with the LAILX complete set of photovoltaic testing instruments to form an integrated mobile testing laboratory. Suzhou LAILX provides full cycle technical services for LXH506, including factory provided sensor calibration certificates, one-on-one deployment and operation training, 24-hour remote technical support, nationwide coverage of equipment maintenance and sensor on-site calibration services, and lifetime free software firmware upgrades.

As the core equipment supporting the entire photovoltaic detection chain, the LXH506 portable weather station has four advantages: no mechanical durable sensing, lightweight and fast deployment, high-precision photovoltaic special monitoring, and multi device data linkage. It fills the gap in outdoor photovoltaic detection meteorological data collection and builds a complete, accurate, and movable environmental data base. In the future, LAILX in Suzhou will continue to deepen the research and development of integrated photovoltaic detection solutions, continuously optimize portable meteorological monitoring technology, improve the entire product line of photovoltaic detection instruments, and empower the digital and standardized operation and maintenance upgrading of the photovoltaic industry with domestically produced high-precision monitoring equipment.
