The power generation performance of photovoltaic modules is greatly affected by meteorological conditions such as solar irradiance, environmental temperature and humidity, wind speed and direction, atmospheric pressure, etc. Meteorological environmental data is an essential basis for IV curve STC conversion, power plant PR performance ratio calculation, power generation evaluation, and fault tracing. Traditional fixed photovoltaic weather stations require a large amount of civil construction, long installation cycles, and fixed monitoring points, which cannot capture local micro meteorological differences in mountainous photovoltaic and multi array distributed power stations; Ordinary simple meteorological monitoring equipment adopts mechanical wind cups and wind vane structures, which are prone to jamming and damage in windy, sandy, and low-temperature environments, with insufficient measurement accuracy, and cannot meet the data standards for photovoltaic acceptance and third-party testing. Shanghai LAILX has launched the LXH506 portable weather station, which adopts an ultrasonic integrated sensing solution, lightweight and fast deployment, and one-stop collection of the full set of meteorological parameters required for photovoltaic detection. It provides a mobile and high-precision environmental monitoring solution for the entire lifecycle of photovoltaic projects. Portable weather station

The core sensing unit of LXH506 portable weather station adopts ultrasonic micrometeorology sensor, abandons the traditional mechanical rotating structure of wind cup vane, and relies on the principle of acoustic wave propagation time difference to measure the wind speed and direction. There are no wearing moving parts, no bearing aging, sand and dust stagnation, low temperature freeze blocking failure and other failures. It is free of routine maintenance, and it works stably in sandstorm, rainstorm, severe cold and hot weather and other harsh outdoor environments. The entire equipment integrates a slope total irradiation sensor, an environmental temperature and humidity probe, an atmospheric pressure sensor, and a component backplate temperature acquisition channel, which can synchronously collect core indicators such as irradiance, environmental temperature, humidity, wind speed, wind direction, and atmospheric pressure. It can also expand the rainfall monitoring module as needed. All sensors have undergone professional metrological calibration, and all measurement indicators comply with domestic photovoltaic testing standards and IEC international testing specifications. The collected data has professional validity and can be directly used for power plant project acceptance, power generation evaluation, outdoor empirical experiments, and synchronized on-site performance testing with IV testers.

The equipment adopts a modular assembly design, and the entire set of instruments is stored in a portable protective box. The tripod can be quickly set up, and a single person can complete the transportation, installation, and debugging. The deployment only takes a few minutes, and the monitoring points can be flexibly switched. It is perfectly adapted to scenarios such as multi-point survey of mountain photovoltaics, temporary acceptance of distributed photovoltaics on roofs, and differential micro meteorological monitoring of multiple arrays, making up for the shortcomings of fixed meteorological stations that cannot be moved. The whole machine is equipped with a large capacity lithium battery, which can support short-term outdoor continuous monitoring without external power supply. It is equipped with a 3-inch high-definition touch color screen, which allows real-time viewing of various meteorological monitoring values on site. The device supports wireless transmission and 4G communication, and can build a multi site network monitoring network. It is equipped with professional data management software to remotely receive, store, and export monitoring data, draw meteorological change curves, and complete long-term series data analysis.

LXH506 portable weather station is suitable for the full process application of photovoltaic projects. In the early stage of resource survey, it is deployed to collect micro meteorological data of the site area, evaluate the potential of local photovoltaic resources, and assist in modeling and calculating power generation; During the construction and acceptance stage of the power station, cooperate with the IV tester and EL tester to carry out on-site testing synchronously, record environmental parameters synchronously, and complete the conversion of component performance STC and the calculation of power station PR value; During the operation and maintenance phase, temporary meteorological monitoring is carried out for abnormal power generation arrays to distinguish whether the decrease in power generation is caused by meteorological fluctuations or equipment failures, and to assist in fault tracing. In addition to the photovoltaic industry, the equipment can also be used for emergency meteorological monitoring, outdoor engineering environment monitoring, scientific research and experimental meteorological data collection, and other scenarios.

Under the trend of refined development in the photovoltaic industry, the accuracy requirements for meteorological basic data in power station performance evaluation continue to increase, and the demand for multi-point and mobile meteorological monitoring is becoming increasingly prominent. The Shanghai LAILX LXH506 portable meteorological station, with its core advantages of no mechanical ultrasonic sensing, rapid deployment, single person operation, multi parameter synchronous acquisition, and wireless remote data management, solves the industry pain points of inconvenient deployment of traditional fixed meteorological stations and insufficient accuracy of simple meteorological equipment, providing reliable environmental data support for photovoltaic performance testing. LAILX continues to improve its photovoltaic full chain detection product matrix, integrating meteorological monitoring, component performance testing, defect imaging, and system efficiency detection equipment to provide integrated detection solutions for photovoltaic power plants and help the industry achieve refined asset management.
