The power generation efficiency of photovoltaic modules is directly affected by meteorological factors such as irradiance, environmental temperature and humidity, wind speed, and atmospheric pressure. IV power testing, module attenuation evaluation, and power generation simulation calculation all require synchronized and accurate meteorological data support. Traditional fixed meteorological stations have long deployment cycles and high infrastructure costs, making it impossible to follow detection personnel to a single array or distributed points on the roof for temporary monitoring; The simple radiometer can only collect single light data and lacks supporting parameters such as temperature, humidity, and wind speed. The calculated component conversion efficiency has a large error and cannot meet the data needs of third-party testing, power plant energy efficiency evaluation, and scientific research experiments. Suzhou Laikesi New Energy Technology Co., Ltd. (LAILX) has launched the LXH506 portable weather station, which meets the exclusive data needs of the photovoltaic detection industry. It integrates ultrasonic multi-element sensing modules, is lightweight and quickly deployed, synchronously collects multi-dimensional meteorological parameters for photovoltaic detection, and provides accurate, real-time, and traceable environmental data for IV curve calibration, component performance evaluation, and power plant generation calculation. It has become a core equipment for photovoltaic on-site detection. Portable weather station

LXH506 adopts an integrated ultrasonic micro meteorological sensing core module, which eliminates the defects of traditional mechanical wind cups, wind indicators that are prone to wear, lag, and large data deviations. It has no mechanical rotating parts, longer service life, and lower maintenance costs. It can synchronously and accurately measure the six core meteorological elements of total irradiance, wind speed, wind direction, environmental temperature, relative humidity, and atmospheric pressure. All sensors are calibrated uniformly at the factory, and the measurement accuracy meets professional meteorological monitoring standards: irradiance accuracy ± 3%, temperature measurement accuracy ± 0.2 ℃, humidity accuracy ± 3% RH, wind speed accuracy ± 0.3m/s, fully matching the STC condition correction requirements in the GB/T photovoltaic module power detection standard. The synchronously collected meteorological data can be directly connected to IV The testing instrument is equipped with analysis software, which automatically completes the standardization correction of component power and conversion efficiency, greatly reducing the measurement error of on-site testing data. The third-party testing agency issues report data with compliance effectiveness.

Portable and rapid deployment is the core design highlight of LXH506. The entire set of equipment includes an integrated sensing host, a scalable aluminum alloy tripod, and a large capacity protective storage box. The weight of the entire set is controlled within 5kg, and it can be easily transported by a single person. After the tripod is stored, it has a compact size and can be easily loaded into car trunk and construction vehicles. The equipment can be assembled immediately after opening the box, and the height of the tripod can be freely adjusted. It is suitable for various work scenarios such as ground photovoltaics, distributed roofs, and steep mountain slopes. No professional tools or civil engineering fixed bases are required throughout the process. The entire setup can be completed in 3 minutes, and data collection will be automatically started upon startup. When it reaches the testing point, it will be put into use immediately. Compared with the deployment cycle of fixed meteorological stations for several days, the efficiency of temporary monitoring has achieved a qualitative leap. The device is equipped with a built-in 12000mAh high-capacity lithium battery and a low-power sensing architecture. When fully charged, it can continuously collect meteorological data for more than 48 hours, meeting the needs of multi day field monitoring. At the same time, an external DC power supply interface is reserved. Long term fixed-point monitoring can be paired with a photovoltaic charging board for continuous battery life, and it can be used in both short-term mobile detection and medium - to long-term fixed-point observation modes.

The data collection and transmission functions are fully adapted to the photovoltaic detection workflow. The device can automatically record continuous 7-day minute level meteorological data locally, with precise synchronization of timestamps. Each set of IV test curves can be matched with corresponding time period meteorological parameters, achieving one-to-one binding of component performance data and environmental data, facilitating energy efficiency traceability and attenuation analysis in the later stage. The communication mode covers both wired and wireless solutions, with a built-in 4G wireless transmission module. In mountainous areas and remote power stations without network cables, real-time meteorological data can be remotely uploaded to the cloud monitoring platform; Equipped with RS485 and RS232 wired interfaces, it can directly connect to the LX-PV33 portable IV tester and computer terminal through wired connection, with real-time data synchronization and interoperability, without the need for manual input, avoiding data errors caused by manual recording. Equipped with LAILX meteorological data analysis software, it can export hourly, daily, and monthly meteorological statistical reports, generate radiation and temperature change curves, and be used for power plant power generation simulation, annual component attenuation evaluation, photovoltaic project revenue calculation, providing data support for project investment and operation optimization.

LXH506 application scenarios cover the entire photovoltaic industry chain testing needs: When third-party testing agencies conduct component IV power sampling, they synchronously collect on-site meteorological data to ensure accurate and compliant testing report data; New photovoltaic power stations will be connected to the grid for acceptance, and meteorological stations will be set up in different arrays to compare the radiation differences in different regions and evaluate the rationality of array layout; Annual energy efficiency evaluation of existing power stations, long-term fixed-point collection of meteorological data, and calculation of component attenuation amplitude based on actual power generation; Outdoor exposure tests in photovoltaic module enterprise laboratories and field observations in university new energy research projects can be adapted; At the same time, it can be extended to multiple scenarios such as wind and solar energy storage projects, agricultural photovoltaics, meteorological emergency monitoring, and field exploration, with one machine serving multiple purposes. In field comparative tests conducted by third-party testing institutions in multiple locations, the power values of the components corrected by LXH506 meteorological station data collection were controlled within 1% deviation from laboratory standard tests, which is far superior to the accuracy of a single radiometer measurement and greatly improves the credibility of the testing report.

The overall protection level of the machine reaches IP65, and the sensing host adopts an anti UV ABS engineering shell, which has the characteristics of rain resistance, dust prevention, salt spray resistance, and high and low temperature resistance. It can work stably in a wide temperature range of -30 ℃ to 70 ℃, and can be used for a long time in northwest sandstorms and southeast coastal high humidity salt spray environments without failure; The sensor surface is designed to prevent the accumulation of rain and snow, ensuring that the detection window will not be obstructed in rainy or snowy weather, and guaranteeing continuous and stable data collection in adverse weather conditions. Suzhou LAILX provides a one-year warranty for the LXH506, a two-year warranty for the sensor core components, and on-site installation, debugging, operation training, and annual calibration services for technical engineers across the country. The data acquisition software is free to iterate and upgrade for life, continuously adapting to the latest data interface requirements of photovoltaic testing standards.
