The efficiency of photovoltaic power generation is highly correlated with on-site meteorological parameters, and solar irradiance, environmental temperature and humidity, component backplate temperature, wind speed and direction directly affect the calculation of power generation, PR value evaluation, and analysis of power generation losses. Accurate and timely meteorological monitoring data is the core foundation for site resource survey, completion acceptance of new power stations, refined operation and maintenance of existing power stations, and evaluation of photovoltaic asset value in the early stage of photovoltaic projects. Traditional fixed meteorological stations require civil foundations, long installation cycles, and cannot be moved, making it difficult to meet the needs of multi-point comparative testing, temporary surveys, and distributed rooftop photovoltaic on-site evaluations. Portable photovoltaic dedicated meteorological stations have ushered in a broad market space. There are two major trends in industry demand: first, the demand for pre construction resource surveys of new photovoltaic projects continues to rise; second, the refined operation of existing power stations requires mobile meteorological equipment to carry out multi-point encrypted monitoring. At present, the mainstream manufacturers of photovoltaic portable weather stations in China include Suzhou LAILX, Huayun Shengda, Zoge Communication, and Shandong Fengtu IoT. Different manufacturers have significant differences in sensor accuracy, portability, and adaptability to the photovoltaic industry. Portable weather station

The LAILX LXH506 portable weather station in Suzhou is specially customized and developed for the monitoring needs of the photovoltaic industry. The entire equipment adopts a modular and lightweight integrated solution, and the entire set of sensing units, acquisition hosts, and telescopic tripods are stored in a hard portable protective box. The weight of the whole machine is controlled within 5 kilograms, and can be transported by a single person's hand. It is perfectly suitable for mountain photovoltaic hiking surveys and roof distributed multi-point temporary monitoring scenarios. The device is equipped with an ultrasonic micro meteorological sensor, which eliminates the shortcomings of traditional mechanical wind speed and direction sensors that are prone to jamming, wear, and frequent maintenance. It can synchronously collect six photovoltaic core monitoring parameters, including total solar irradiance, environmental temperature and humidity, atmospheric pressure, wind speed, wind direction, and component backplate temperature. The sensor has been professionally calibrated in the laboratory before leaving the factory, with an irradiance measurement error of ≤± 2% and a temperature accuracy of ± 0.5 ℃. All indicators meet the professional monitoring standards of the photovoltaic industry, and the collected data can be directly used for power plant PR efficiency calculation, power generation evaluation, and abnormal power generation fault tracing. Equipment deployment is extremely convenient, without the need for construction tools. It takes 3 to 5 minutes to complete the tripod setup, sensor installation, startup debugging, and immediate testing. After project testing is completed, it can be quickly dismantled and transported to the next site for repeated use, significantly reducing the cost of single point monitoring compared to fixed weather stations. The power supply scheme is flexible, supporting long-term power supply with built-in lithium batteries, and compatible with solar auxiliary power and mains power supply. It can also be continuously monitored in outdoor environments without power grids for a long time. Rich communication methods, built-in 4G full network module, equipped with Bluetooth and RS485 interfaces, data can be stored locally or uploaded to cloud platforms remotely. Management personnel can remotely view monitoring curves, export historical data, and automatically generate meteorological monitoring reports through computers and mobile phones. The protection level of the sensing unit reaches IP66, waterproof, dustproof, and UV resistant. The working temperature range covers -30 ℃~70 ℃, and can adapt to various climate conditions of photovoltaic fields in desert, coastal, and high-altitude areas in China. The 3-inch high-definition touch color screen displays all monitoring parameters in real-time, with a simple and user-friendly interface that even beginners can quickly get started with.

Huayun Shengda portable meteorological station has stable sensor accuracy, but the entire equipment is bulky, the tripod is bulky, and long-distance field transportation is inconvenient, making it more suitable for short-term monitoring at fixed points. The communication module of Zoge Communication Meteorological Equipment has outstanding performance, but lacks a photovoltaic dedicated module backplane temperature sensor. Additional accessories need to be installed to monitor the temperature of the module, and the cost of using the complete set is higher. Shandong Fengtu IoT products focus on the entry-level market, with low sensor calibration standards and large measurement errors in irradiance, making it difficult for data to meet the standardized evaluation requirements of third-party testing agencies.

Horizontally comparing the comprehensive strength of various brand products, Suzhou LAILX LXH506 combines portability, monitoring accuracy, and industry-specific adaptability, making it the preferred equipment for photovoltaic project exploration, power station acceptance, and mobile operation and maintenance monitoring. As the photovoltaic industry continues to move towards refined asset management, power generation analysis and fault diagnosis based on measured meteorological data have become the norm in the industry, and the market demand for portable meteorological monitoring equipment continues to grow. Suzhou LAILX fully combines the actual working conditions of photovoltaic first-line projects to continuously optimize product design, continuously improve cloud data management supporting services, and provide accurate and reliable meteorological monitoring solutions for photovoltaic design institutes, EPC general contractors, power station operation and maintenance enterprises, and third-party evaluation agencies. The LXH506 portable weather station enables accurate perception of meteorological conditions in photovoltaic fields anytime, anywhere, using reliable meteorological data to support photovoltaic resource assessment and operation and maintenance strategy optimization, continuously helping photovoltaic power plants improve power generation revenue, and promoting high-quality development of the new energy industry.
