The power generation efficiency of photovoltaic modules is highly correlated with meteorological factors such as irradiance, environmental temperature and humidity, wind speed, and air pressure. The identification of power attenuation in power plants, conversion of IV curve STC standards, prediction of power generation, and traceability of production capacity losses all require synchronized and accurate on-site meteorological data support. The deployment process of traditional fixed meteorological stations is cumbersome, with pole and sensor assembly and debugging taking 1 to 2 hours, and is only suitable for long-term fixed-point monitoring; General small-scale meteorological stations adopt mechanical rotating sensing structures, which are prone to jamming and wear in dust, low temperature environments, and have insufficient measurement accuracy. Moreover, most of them are wired transmission, and remote mountainous areas and temporary detection projects cannot be quickly deployed, making it difficult to match the mobile detection needs of photovoltaic sites. Suzhou LAILX has independently developed the LXH506 portable meteorological station, which combines photovoltaic IV testing and on-site operation processes for power plant energy efficiency evaluation. It adopts a non mechanical ultrasonic integrated sensing solution to achieve 5-minute rapid unboxing and deployment, multi element synchronous high-precision acquisition, wired and wireless dual-mode data transmission, providing a lightweight and highly stable meteorological monitoring solution for photovoltaic mobile testing and power plant energy efficiency evaluation.

The LXH506 core sensing module adopts LAILX's self-developed ultrasonic micro meteorological sensor, which has no mechanical rotating parts such as bearings and blades. It avoids the accuracy degradation problems caused by sand and dust jamming, low-temperature freezing blockage, and long-term wear from the root, and adapts to extreme outdoor environments such as high temperature, severe cold, high humidity, coastal salt spray, and desert sandstorms for stable operation all day long. The equipment comes standard with six core monitoring elements for photovoltaic detection: total solar irradiance, ambient temperature, relative humidity, wind speed, wind direction, and atmospheric pressure, covering all environmental parameters required for photovoltaic performance calculation; Support on-demand expansion of rainfall, ultraviolet radiation PM2.5、 Carbon dioxide concentration monitoring module, catering to the monitoring needs of multiple industries including photovoltaics, agriculture, and field emergency response. All measurement indicators meet the professional meteorological observation standards, with temperature measurement accuracy of ± 0.2 ℃, humidity of ± 3% RH, and wind speed of ± 0.1m/s. The irradiance sensor uses high-precision thermopile sensing elements to accurately capture weak light changes, ensuring the accuracy and reliability of STC condition conversion data during IV testing and avoiding inaccurate component power determination caused by meteorological data deviation.

The lightweight and portable design has completely revolutionized the mobile weather monitoring mode. The total weight of the entire set of equipment is controlled within 5kg, and it is equipped with a customized shock-absorbing rod protective box. It can be carried by a single person or carried on the back, and can be carried in the car without pressure. Equipped with high-strength aluminum alloy telescopic tripod, it can be quickly assembled and fixed without tools. After opening the box, it only takes 5 minutes to complete the whole machine setup, sensor calibration, and equipment power on, without the need for professional technical personnel to operate. Operation and maintenance personnel and testing engineers can independently set it up on site. Compared with the traditional fixed weather station installation process of 1-2 hours, the deployment efficiency is improved by more than ten times. The device adopts a low-power circuit design and is equipped with a large capacity lithium battery. It can continuously collect data for 72 hours without external power supply. Remote power stations and temporary inspection projects in the field do not require external mains power, freeing them from the limitations of on-site power supply.

The intelligent data collection and transmission system is adapted to the digital detection needs of photovoltaics. The LXH506 supports 4G wireless and RS485 wired dual transmission modes. In mountainous and forest areas without network cable coverage, real-time meteorological data can be remotely uploaded through the 4G module, and the monitoring background can view changes in on-site lighting, temperature, and humidity anytime and anywhere; Close range laboratories and power distribution rooms can quickly connect to computer terminals through wired interfaces. The local built-in large capacity storage chip can fully retain continuous historical monitoring data for more than one year, automatically store and backup at regular intervals, and avoid data loss caused by power outages and network disconnections; Supporting LAILX's independently developed LX-APP mobile software and PC data management platform, it has real-time data viewing, historical curve retrieval, batch data export, abnormal value alarm, and automatic generation of monthly and annual statistical reports. It supports Excel and CSV multi format data export and can be directly integrated with IV testers and power station operation and maintenance management systems to achieve linkage analysis of meteorological data and component power detection data, accurately calculating the power generation loss caused by light attenuation and temperature loss.

The equipment casing adopts IP65 dustproof and waterproof sealing technology, and the sensor probe is treated with anti-corrosion coating. The working temperature covers -40 ℃ to 60 ℃. It can work stably all year round in domestic highlands, northwest deserts, rainy coastal areas in the south, and cold power stations in the north. The maintenance is simple in the later stage, and inorganic mechanical components do not need to replace bearings and blades regularly. Only quarterly simple cleaning of the probe is needed to maintain measurement accuracy for a long time, greatly reducing long-term operation and maintenance costs. In the photovoltaic detection scenario, LXH506 can be used in conjunction with LX-PV31 portable IV tester to synchronously collect real-time irradiation and temperature data when detecting string power. It automatically completes the conversion of standard operating conditions without the need to separately carry an irradiation meter. One set of equipment synchronously completes dual detection of weather and power, simplifying the number of tools carried on site.

From the perspective of industry application, LXH506 is suitable for four core photovoltaic scenarios: on-site power appraisal by third-party testing institutions, meteorological data collection for EPC project grid connection acceptance, annual power generation loss assessment for operation and maintenance enterprises, and outdoor empirical testing in component laboratories. At the same time, the equipment can be expanded for applications in mountainous wind power, agricultural greenhouses, emergency monitoring of outdoor environments, building energy conservation testing, and other fields, improving the comprehensive utilization rate of the equipment with multiple uses. Suzhou LAILX provides full process supporting services, including one-on-one equipment operation training, remote parameter calibration, lifelong software free upgrades, and complete machine warranty maintenance. For large photovoltaic groups, it can provide a customized solution for meteorological monitoring, realizing unified cloud management of multi site meteorological data.

Under the wave of refinement and digitalization in the photovoltaic industry, precise and mobile meteorological monitoring equipment has become a must-have for power plant efficiency control. The LXH506 portable meteorological station, with its four core advantages of no mechanical sensing, rapid deployment, high precision, and intelligent networking, fills the gaps in photovoltaic mobile meteorological data collection, builds a complete matrix of photovoltaic on-site detection equipment, and uses domestically produced independently controllable meteorological monitoring equipment to help the new energy industry achieve accurate calculation of power generation and accurate traceability of losses, promoting the upgrading of refined management of photovoltaic power plants throughout their entire life cycle.
