The output performance of photovoltaic modules is highly dependent on on-site meteorological conditions, including total solar irradiance, ambient temperature, module backplate temperature, wind speed and direction, humidity, and air pressure. They are essential basic environmental parameters for IV curve testing, EL detection, power plant PR value evaluation, and power generation calculation. Traditional fixed photovoltaic weather stations require civil construction, long installation cycles, fixed equipment locations, and can only collect data from a single point. Faced with mountainous photovoltaic, multi area ground power stations, and multi-point distributed roof projects, there are significant microclimate differences between different arrays, and single station data cannot represent the true working conditions of each array, which can easily lead to performance evaluation deviations. Fixed weather stations are also unable to follow the movement of the inspection team, making it difficult to synchronize meteorological data from the measured points when conducting on-site sampling inspections. Suzhou Laikesi LAILX aims to meet the mobile monitoring needs of photovoltaic sites and has launched the LXH506 portable weather station. It adopts an integrated ultrasonic sensing solution, lightweight and rapid deployment, and achieves synchronous collection of multiple meteorological parameters. It provides a reliable mobile environmental monitoring solution for photovoltaic resource survey, on-site detection, and power station operation and maintenance. Portable weather station

The LXH506 portable weather station is designed specifically for new energy outdoor scenarios. The core sensing unit adopts ultrasonic integrated sensors, without mechanical rotating parts, which will not cause problems such as wind and sand jamming or icing failure. The equipment can synchronously collect multiple key parameters such as total solar irradiance, environmental temperature and humidity, component backplate temperature, wind speed, wind direction, atmospheric pressure, etc., fully covering all meteorological elements required for photovoltaic detection. The sensors are calibrated at the factory, and the measurement accuracy meets the detection standards of the photovoltaic industry. The entire set of equipment is modularized and disassembled, with sensor units, data acquisition hosts, and lightweight aluminum alloy tripods all stored in a hard portable protective box. The entire set is lightweight and can be transported by a single person's hand. After arriving at the testing site, the tripod is quickly set up, the assembly process is simple, and it can be fully deployed in a few minutes. It can be put into monitoring immediately after opening the box and starting up, without the need for civil infrastructure. It truly achieves on-demand testing. The testing team can deploy the meteorological station at the corresponding location and obtain environmental data that is completely synchronized with the tested components in which array they go to carry out IV and EL testing.

On the power supply mode, the device is equipped with a large capacity lithium battery, which can work continuously for a long time outdoors without mains power. At the same time, it supports external DC power supply to meet the needs of long-term on-site monitoring. Rich communication methods, supporting local storage, wired data export, as well as wireless transmission and 4G remote data upload. It can read real-time values locally and remotely retrieve historical monitoring records. Equipped with exclusive data management software, it automatically stores all meteorological historical data, supports data query, curve playback, statistical analysis, and automatically generates daily and weekly reports for easy organization and archiving by testing personnel. With the help of LAILX's IV tester, EL tester and other equipment, it can achieve linkage comparison between environmental parameters and component performance data, and more accurately complete component power correction and power station performance analysis. The equipment casing has a high level of protection and can adapt to working in a wide temperature range of -40 ℃ to 85 ℃. It is dustproof, waterproof, and corrosion-resistant, and can operate stably in various harsh power plant environments such as deserts, plateaus, coastal high salt spray, and mountain sandstorms. The sensors support automatic calibration, reducing maintenance workload in the later stage.

The application scenarios of LXH506 portable weather station are very diverse. In the early survey stage of photovoltaic projects, short-term meteorological observations can be carried out at the proposed site to evaluate local radiation resources and provide first-hand data for power plant design and power generation forecasting; During the acceptance inspection of the power station, it is synchronized with the IV and EL inspection work to collect real meteorological data of the tested array points, ensuring the accuracy of power conversion and performance evaluation; During the operation and maintenance fault analysis process, when the power station experiences abnormal power generation, it is necessary to move to the abnormal array point for monitoring to distinguish whether it is equipment failure or fluctuations in power generation caused by local micro weather or obstruction; At the same time, it is suitable for third-party testing institutions to conduct outdoor sampling testing and scientific research units to conduct outdoor empirical experiments. In the past, in order to obtain multi-point meteorological data, the industry could only invest high costs to build multiple fixed meteorological stations. The LXH506 portable meteorological station, with a mobile approach, solves the problem of multi-point environmental monitoring with less investment. With the continuous improvement of photovoltaic testing standards, the requirements for synchronous recording of environmental parameters during the testing process are becoming increasingly strict. The LAILX LXH506 portable weather station fills the gap in environmental data for mobile testing, and forms a complete photovoltaic testing equipment matrix with IV testers, EL testers, thermal imaging equipment, and inverter testers, helping the photovoltaic industry's testing work develop towards more accurate, rigorous, and standardized directions, providing a solid data foundation for photovoltaic project asset evaluation and operation and maintenance decision-making.
