Meteorological factors such as irradiance, temperature, wind speed, and direction are the fundamental basis for all performance calculations in the photovoltaic industry. The output power of photovoltaic modules is highly dependent on solar radiation, and environmental temperature and wind speed can significantly affect the operating temperature of the modules, thereby changing the actual power generation capacity. In the preliminary survey, grid connection acceptance, and on-site performance testing of the power station, reliable meteorological data needs to be collected synchronously to convert the measured power to standard testing conditions and calculate the system PR value. The installation and construction of traditional fixed meteorological stations are complex and costly, with fixed locations that cannot be moved. Faced with scenarios such as multi-point survey of mountain photovoltaics, acceptance of distributed rooftop photovoltaics, and temporary comparative tests, it is difficult to use them flexibly. Suzhou LAILX has launched the LXH506 portable weather station, which adopts an ultrasonic integrated sensing architecture to achieve rapid installation, portable mobility, and high-precision monitoring of multiple elements, filling the market demand gap for photovoltaic mobile weather monitoring equipment. Portable weather station

The LXH506 core is equipped with an ultrasonic micro meteorological sensor, which abandons traditional mechanical wind cup wind indicators and eliminates mechanical rotating parts, eliminating the hidden danger of mechanical wear and tear. The equipment has a longer service life and lower maintenance workload. One device synchronously completes the measurement of six core elements including total solar irradiance, ambient temperature, relative humidity, wind speed, wind direction, and atmospheric pressure. All sensors have been professionally calibrated in the laboratory and meet the relevant specifications for photovoltaic power station testing. The wind speed measurement range is 0-60m/s, the wind direction is 0-360 °, the irradiance measurement accuracy is better than ± 3%, and the temperature and humidity measurement accuracy meets the requirements of photovoltaic detection. At the same time, an external component backplane temperature sensor can be connected to directly obtain the working temperature of the component, fully covering all environmental parameters required for photovoltaic detection. The device supports free setting of the collection cycle, which can be used for short-term on-site testing for a few hours, as well as for long-term fixed-point continuous observation for several months, taking into account both temporary survey and long-term monitoring modes.

Portable and fast deployment is the core competitiveness of LXH506. The whole machine adopts a modular assembly structure, which does not require special tools. The staff can complete the tripod setup, sensor installation and debugging in a short time. The entire set of equipment is stored in a protective box, with a total weight controlled within 5kg. It can be easily transported by a single person, and can be quickly deployed in inconvenient transportation locations such as mountains and rooftops. The equipment is equipped with solar assisted power supply, and outdoor operations can rely on solar energy to supplement power, reducing the trouble of frequent battery replacement; At the same time, it has built-in large capacity local storage, which can store raw monitoring data at the minute level for more than one year, and supports USB local export of all historical records. The device supports wireless data transmission and can remotely read real-time meteorological data. It has an open standardized data interface and can be linked with LAILX series IV testers and inverter testers to detect performance parameters while synchronously obtaining meteorological data. It automatically completes power STC conversion, making the data in on-site inspection reports more authoritative and compliant. The whole machine is equipped with signal lightning protection and power reverse protection, with a high protection level. It can operate stably in outdoor environments such as sandstorms, rainfall, and high and low temperatures, reducing the risk of equipment damage in the field.
LXH506 runs through multiple application scenarios throughout the entire lifecycle of photovoltaic projects. In the early stage of project resource survey, it is used to collect micro meteorological data from multiple locations for candidate sites, evaluate the local photovoltaic development potential, and assist in investment income calculation; During the grid connection acceptance stage of the power station, temporary arrangements were made to collect continuous meteorological data and cooperate with component performance testing to ensure the smooth progress of the acceptance power evaluation work; During the operation and maintenance phase of existing power stations, multiple points can be moved and distributed to compare the differences in irradiation temperature between different arrays, analyze the causes of uneven power generation, and guide the development of component cleaning and fault maintenance plans; When third-party testing institutions conduct performance appraisal and power generation loss assessment of power plants, they are used as standard environmental monitoring equipment; It is also suitable for scientific research experiments, agricultural photovoltaic complementary bases, and meteorological observations of wind solar energy storage projects. Multiple devices support network synchronization monitoring, and meteorological data is collected simultaneously in different areas of large ground power stations to evaluate the power generation losses caused by terrain obstruction, providing data support for the optimization and renovation of power stations. The equipment is equipped with PC data analysis software, which can link meteorological data with power generation data for analysis, quantify the impact of various environmental factors on power generation, and export Excel and PDF format reports for archiving and saving with one click.

Today, as the photovoltaic industry moves towards precision and digitization, accurate and reliable micro meteorological data is a prerequisite for scientifically evaluating the efficiency of power plants. The LXH506 portable weather station solves the pain point of insufficient flexibility of traditional fixed weather stations, turning high-precision weather monitoring capabilities into mobile on-site equipment. Suzhou LAILX realizes the localization and self-developed of sensors, acquisition motherboards, and analysis software, providing a complete set of services such as equipment training, regular sensor calibration, and free software upgrades. It provides reliable mobile meteorological monitoring solutions for photovoltaic design institutes, EPC enterprises, operation and maintenance companies, and third-party testing institutions, helping the photovoltaic industry achieve more scientific and accurate power generation evaluation and operation and maintenance management.
