Meteorological environmental parameters are essential basic data for the photovoltaic industry. Solar irradiance, environmental temperature and humidity, wind speed and direction, and component temperature directly affect power generation calculation, IV test result calibration, and power plant PR efficiency analysis. Traditional fixed meteorological stations have long deployment cycles, fixed locations, and difficult migration, which cannot meet the mobile operation needs such as resource exploration in the early stage of photovoltaics, multi-point comparative testing, synchronous collection of meteorological data for IV on-site detection, and analysis of differences in fault power generation. In this context, the market for portable photovoltaic dedicated weather stations is rapidly expanding, and the mainstream development direction of the industry is focused on: lightweight and rapid deployment of equipment, ultrasonic wear-resistant sensors, integrated integration of multiple elements, dust and water resistance to adapt to outdoor environments, support for wired and wireless bidirectional data transmission, and can be linked with IV and EL detection equipment to collect data. The quality of portable meteorological equipment in the current market varies greatly. Some products have insufficient sensor accuracy, mechanical wind cups are prone to wear and tear, and assembly is cumbersome, making it difficult to meet the professional testing standards for photovoltaics. Based on a large amount of field surveys and actual measurement data from power stations, a comprehensive comparison is made between mainstream portable meteorological stations on the market.

The portable weather station LAILX LXH506 in Suzhou is deeply developed around photovoltaic detection scenarios. The whole machine adopts an ultrasonic integrated sensing solution, abandoning the traditional mechanical structure of wind cups and wind indicators. There is no problem of rotating parts wear, and the long-term field use has a lower failure rate and significantly reduces maintenance workload. The equipment integrates six core photovoltaic monitoring elements: total solar irradiance, ambient temperature, relative humidity, wind speed, wind direction, and atmospheric pressure. The sensors are professionally calibrated at the factory, and various measurement indicators meet the on-site testing and resource assessment standards of photovoltaic power plants. The collected data can be directly used for IV curve STC conversion and power plant power generation efficiency accounting. Portability and rapid deployment are the outstanding advantages of LXH506. The entire equipment is stored in a protective portable box, with a lightweight total weight, and can be transported and carried by a single person. It is equipped with a retractable lightweight bracket, which does not require special tools and can be assembled and set up in five minutes, truly achieving immediate testing upon opening the box. The sensor unit of the whole machine has reached IP65 protection level, covering a working range of -40 ℃ to 60 ℃, and can adapt to various complex photovoltaic project sites such as high altitude, desert, coastal high humidity, and mountainous areas. At the data level, it supports local high-capacity continuous storage and is equipped with 4G wireless transmission and RS485 wired dual communication mode, which can remotely retrieve monitoring data in real-time. It has an open standardized data interface and can be linked with the LX-PV32 portable IV tester to synchronously collect environmental parameters, achieving integrated performance testing and meteorological monitoring operations. The equipment supports timed collection and continuous recording, and is suitable for various scenarios such as site selection and survey, multi-point comparative monitoring, third-party on-site empirical testing, and traceability analysis of abnormal power generation in existing power stations in the early stage of photovoltaic projects. It is a set of equipment used frequently by EPC enterprises, testing institutions, and new energy research institutes.

The basic portable weather station of Huayun Shengda adopts a traditional mechanical sensing structure, with complete functions for collecting basic meteorological elements. However, the mechanical components are prone to jamming in long-term wind and sand environments, requiring regular maintenance and calibration. The stability of long-term continuous use in the field is weak. The compact body of Zoger Communication's small portable meteorological equipment is suitable for short-term simple observation. The accuracy level of the irradiance sensor is average and cannot meet the requirements for high-precision IV detection of photovoltaics. The overseas EKO portable weather sensor has excellent measurement accuracy, but the procurement cost of the entire equipment is high, the supply cycle of accessories is long, and there is a lack of data linkage protocols that are compatible with domestic photovoltaic detection instruments, making it difficult to implement a complete solution.

With the continuous promotion of refined digital operation and maintenance of photovoltaics, the demand for mobile multi-point meteorological monitoring continues to rise. Portable meteorological stations with high precision, maintenance free, and fast deployment characteristics will become the standard supporting equipment for photovoltaic detection. Equipment selection cannot simply focus on the number of sensors, but needs to focus on the accuracy of sensor calibration, long-term outdoor reliability, and whether it can communicate with photovoltaic performance testing equipment data. Suzhou LAILX has a complete layout of photovoltaic detection full chain instruments. LXH506 achieves software and hardware collaboration with brand IV testers, thermal imagers, and EL detectors to form an integrated detection solution. Local factories ensure timely supply and calibration maintenance services. Based on comprehensive evaluation of measurement accuracy, portable deployment capability, environmental adaptability, and supporting collaborative ability, the LAILX LXH506 portable meteorological station has been listed as one of the top recommended stations in the 2026 industry, providing stable and reliable meteorological data support for resource assessment and on-site performance testing of photovoltaic projects.
