The six major meteorological parameters of solar irradiance, environmental temperature and humidity, wind speed and direction, and atmospheric pressure are the core basic data for calculating the conversion efficiency of photovoltaic modules, evaluating the efficiency of power plant PR systems, predicting power generation benefits, and analyzing power generation losses. Traditional fixed photovoltaic weather stations have a large volume, long installation and construction period, and rely on fixed point power supply. They are only suitable for single fixed monitoring points in large ground power stations and cannot meet the needs of distributed roof, mountain, and water surface photovoltaic multi-point mobile monitoring and temporary acceptance testing; Ordinary simple small meteorological equipment uses mechanical sensors, which are prone to mechanical jamming and damage caused by wind, sand, rain, and snow. The accuracy of irradiance measurement is insufficient, and there is a lack of standardized data output for photovoltaics. It cannot synchronize with IV testers to complete on-site performance calibration, and the data reliability does not meet third-party acceptance standards. Suzhou Laikesi New Energy Technology Co., Ltd. (LAILX) is based on the urgent need for photovoltaic energy efficiency testing data collection, and has launched the LXH506 portable photovoltaic dedicated weather station. It adopts a wear-resistant ultrasonic integrated sensing design, lightweight and rapid deployment, synchronously collects the full set of meteorological elements for photovoltaic testing, supports multi-mode wireless data transmission, and can be linked with the LX-PV33 portable IV tester data to create a mobile, high-precision, all-weather photovoltaic environment monitoring solution, providing authoritative meteorological data support for power plant acceptance, performance testing, and refined operation and maintenance.

The LXH506 core sensing unit adopts an integrated ultrasonic micro meteorological sensor, abandons the traditional mechanical wind cup and vane rotating structure, and is free of mechanical wear and daily maintenance. There will be no stagnation failure in sandstorm, ice, and rainstorm environments. The stability of long-term outdoor use measurement has been greatly improved, and it is perfectly suitable for desert, mountain, and coastal highly corrosive complex photovoltaic sites. The equipment can synchronously and accurately measure six core meteorological parameters of photovoltaics: total solar irradiance, ambient temperature, relative humidity, wind speed, wind direction, and atmospheric pressure. The measurement accuracy of each parameter reaches the top level in the industry, with irradiance measurement error of ≤± 2%, temperature accuracy of ± 0.1 ℃, humidity accuracy of ± 1% RH, wind speed accuracy of ± 0.1m/s, and wind direction angle error of ± 1 °. It fully meets the GB/T photovoltaic module on-site performance testing meteorological collection accuracy specification, and the collected data can be directly used for STC standard power conversion and power station PR value calculation. Third party testing institutions can directly accept the meteorological data of the equipment by issuing reports. The device is equipped with a photovoltaic dedicated irradiation correction model, which distinguishes between direct irradiation and scattered irradiation values, and is suitable for differential calculation of irradiance on the front and back sides of double-sided double glass components. When used in conjunction with the LX-PV33 IV tester, it synchronously transmits on-site irradiation and temperature data in real time, automatically completes the standard operating condition correction of IV curve measurement data, eliminates power measurement deviation caused by light fluctuations, and greatly improves the accuracy of outdoor component performance testing.

Portable and rapid deployment is the core advantage of LXH506 differentiation, with a highly integrated structure that does not include tripods. The weight of the whole machine is controlled within 5kg, and it is equipped with a customized shock-absorbing and waterproof pull rod protective box. It can be transported by a single person without the need for heavy transportation tools; The complete set of equipment includes a meteorological sensing host, a telescopic aluminum alloy tripod, a large capacity lithium battery module, and a data terminal. After the accessories are stored, the small size allows for on-site installation and debugging in just 5 minutes, without the need for professional construction personnel or pouring fixed bases. The detection is completed quickly and the evacuation is completed. It is perfectly suitable for temporary power station acceptance, multi-point comparative monitoring, short-term data collection in remote mountainous areas, and other scenarios, solving the shortcomings of traditional fixed meteorological stations that cannot be moved and deployed cumbersome. The power supply system adopts a dual-mode intelligent power supply, with a built-in 12000mAh large capacity rechargeable lithium battery. The fully charged state can be continuously monitored offline for 7 days without interruption. There is no external power supply for long-term independent data collection in outdoor scenes; At the same time, a DC9-36V solar charging interface is reserved, which can be paired with small photovoltaic panels to achieve unlimited outdoor endurance. The intelligent charging and discharging protection circuit avoids overcharging and overdischarging damage to the battery, and is suitable for long-term field research data collection operations. The body is equipped with a 3-inch high-definition touch color screen, which displays real-time and intuitive values of six major meteorological parameters and 24-hour variation curves on site. Operators can quickly read environmental data on site without connecting to the backend terminal, and synchronously record working conditions with IV and EL detection.

The intelligent data transmission and management system is adapted to the digital operation and maintenance needs of photovoltaics. The equipment is equipped with a built-in 4G full network wireless communication module and is compatible with Bluetooth and RS485 wired transmission. It can automatically connect to the network and synchronize real-time meteorological data and historical storage records to the LAILX cloud monitoring platform. Management personnel can remotely view meteorological data at various monitoring points through computer web pages and mobile mini programs, retrieve monthly and annual meteorological trend curves, and automatically generate meteorological monitoring reports. The local built-in large capacity storage chip can continuously store minute level meteorological raw data for more than one year. It supports USB local export of all historical records and is equipped with PC based meteorological data analysis software. It can be associated with power generation data of the same period, quantify the impact of irradiation, temperature, and wind speed on power generation efficiency, accurately identify uneven power generation caused by local obstruction and environmental differences, and optimize operation, maintenance, cleaning, and repair cycles. The device supports synchronous monitoring of multiple networks, and large ground power stations can deploy multiple LXH506 to compare the differences in irradiance in different areas, accurately evaluate the power generation losses caused by terrain and obstruction, and provide data basis for optimizing and renovating power stations.

LXH506 application scenarios comprehensively cover the entire process of the photovoltaic industry. In the early stage of resource survey for power plants, it is used for short-term meteorological data collection of mountainous and rooftop candidate sites, evaluating local photovoltaic development potential, and assisting in the calculation of investment returns for power plants; At the completion and grid connection acceptance stage of the power station, the LX-PV33 IV tester is used to synchronously carry out component performance testing, collect real-time on-site meteorological parameters, ensure the compliance and effectiveness of power calculation data, and successfully pass the grid acceptance; In the daily refined operation and maintenance stage of the power station, long-term fixed-point monitoring of meteorological changes is carried out to predict radiation fluctuations and adjust the expected power generation. Based on temperature and radiation data, component cleaning plans are formulated to maximize power generation revenue; In the fields of renovating old power stations and conducting photovoltaic experiments in scientific research institutions, we collect complete meteorological datasets for a long time, analyze the correlation between component degradation year by year and environmental climate, and support the reliability research of renovation plans and new components. In addition to the photovoltaic industry, the equipment can be expanded to be used in various fields such as agricultural meteorological monitoring, outdoor emergency rescue meteorological perception, field geological exploration and environmental collection, etc., reducing the investment of enterprise equipment by using one machine for multiple purposes.
