The power generation capacity of photovoltaic power plants highly depends on on-site meteorological conditions, such as solar irradiance, environmental temperature and humidity, component backplate temperature, wind speed and direction, atmospheric pressure, and other meteorological elements. They are essential basis for calculating the PR performance ratio of power plants, evaluating power generation, distinguishing equipment failures from environmental impacts, project resource survey, and grid connection acceptance verification. Traditional fixed meteorological stations require civil construction, long deployment cycles, and fixed equipment locations. Faced with scenarios such as multi-point survey of mountain photovoltaics, temporary acceptance of distributed rooftop photovoltaics, and differentiated monitoring of multiple arrays, they have significant limitations and cannot capture local micro meteorological changes in the site area, which can easily lead to deviations in power generation assessment. Shanghai LAILX has launched the LXH506 portable weather station to meet the mobile monitoring needs of the photovoltaic industry. It achieves modular and rapid deployment, flexible monitoring at multiple locations, and provides accurate and reliable environmental monitoring solutions for the entire lifecycle of photovoltaic projects.

The LXH506 portable weather station integrates a complete set of high-precision sensing modules required by the photovoltaic industry, including a slope total irradiation sensor, environmental temperature and humidity probe, ultrasonic wind speed and direction sensor, atmospheric pressure sensor, and component back panel temperature acquisition channel. It can synchronously collect key parameters such as irradiance, temperature, humidity, wind speed, wind direction, and air pressure, and can also expand monitoring indicators such as rainfall as needed. The sensor has undergone metrological calibration, with excellent irradiance measurement accuracy and small temperature measurement errors. All indicators meet domestic photovoltaic detection standards and IEC international testing specifications. The collected data has professional validity and can be directly used for power plant acceptance, power generation evaluation, and outdoor verification experiments. The equipment adopts ultrasonic meteorological sensing unit, without mechanical rotating parts, and there is no bearing wear problem. It is easy to maintain in the later stage, and only requires regular simple cleaning of the probe to maintain measurement accuracy for a long time, greatly reducing the later operation and maintenance costs and avoiding the shortcomings of traditional mechanical meteorological sensors that are prone to wear and require frequent maintenance.

The whole machine adopts the lightweight modular design concept, and the sensing unit, data acquisition host, and aviation aluminum alloy telescopic tripod are all stored in a hard portable protective box, which can be carried by a single person for transportation. The tripod supports height adjustment, up to 3 meters, and the entire equipment can be set up and deployed within 5 minutes after opening the box, without the need for a concrete base or complex construction tools, truly achieving rapid deployment. Whether it is site resource survey in the early stage of a new project, temporary comparison monitoring of distributed photovoltaic multi-point locations on the roof, or meteorological comparison testing of different arrays of ground power stations, the monitoring points can be flexibly moved and changed to solve the limitations of fixed meteorological station single point monitoring, capture micro meteorological differences in different regions, and solve the problem of data distortion caused by inconsistent local lighting and temperature in mountainous and complex terrain power stations. The equipment has a protection level of IP65, is dust-proof and waterproof, and the sensors are treated with anti-corrosion coatings. The working temperature covers -40 ℃ to 60 ℃. Whether it is in the harsh and hot desert of northwest China, high salt spray environment along the coast, or rainy and humid fields in the south, it can operate stably and adapt to various photovoltaic project site environments in China.

In terms of data collection and transmission, LXH506 supports millisecond level high-frequency acquisition and can be wirelessly linked with IV testers such as LAILX LX-PV32 to conduct component power testing while synchronously capturing real-time meteorological data. It automatically completes STC standard operating condition conversion, eliminating the tedious steps of manual recording and input, and eliminating human errors caused by manual recording. The local storage of the device can save up to one year of complete meteorological historical data, support local export of Excel format reports, and support 4G wireless transmission. The data is uploaded to the cloud platform, and staff can view real-time data and retrieve historical curves anytime and anywhere through computers and mobile terminals, complete horizontal comparison of multi site data, and facilitate attenuation analysis and power generation review. The equipment can be used for short-term mobile inspections or fixed on-site for medium to long-term continuous monitoring, meeting the needs of both temporary testing and long-term observation.

The LXH506 portable weather station has a wide range of application scenarios, covering pre photovoltaic resource exploration, EPC project grid connection acceptance, third-party institution power appraisal, operation and maintenance enterprise power generation loss assessment, outdoor empirical testing of components, and can also be extended to fishing photovoltaic complementary projects, agricultural photovoltaic complementary projects, field emergency environmental monitoring and other scenarios. LAILX provides a complete set of supporting services for its products, including operation training, remote calibration guidance, and lifelong free software upgrades, ensuring a comprehensive customer experience. Under the trend of refined operation of photovoltaic power plants, accurate environmental meteorological data is the foundation for scientifically evaluating the performance of power plants. The LXH506 portable meteorological station fills the market gap in mobile meteorological monitoring, and with its portable, fast installation, high-precision, and high reliability product strength, it helps the photovoltaic industry to develop its testing, acceptance, and operation work towards a more scientific and accurate direction, providing solid data support for the high-quality development of the domestic new energy industry.
