The efficiency of photovoltaic power generation is highly correlated with the meteorological conditions of the site. Meteorological parameters such as solar irradiance, ambient temperature, module back panel temperature, wind speed, wind direction, atmospheric pressure, etc. are indispensable basic data for photovoltaic resource survey, theoretical calculation of power generation, evaluation of power plant PR value, and determination of fault causes. Traditional fixed photovoltaic weather stations require foundation construction, fixed point locations, long construction periods, high investment costs, and cannot achieve multi-point mobile monitoring. There are significant local microclimate differences between mountainous photovoltaics and multi area rooftop distributed photovoltaics. The data collected by a single fixed meteorological station is difficult to represent the true working conditions of the entire site, which can easily cause distortion in power generation assessment and make it difficult to distinguish whether power generation fluctuations are caused by weather factors or equipment failures. Suzhou Laikesi LAILX has launched the LXH506 portable weather station, with a modular and lightweight design that enables flexible deployment of weather monitoring equipment, providing accurate environmental monitoring solutions for the entire lifecycle of photovoltaic projects. Portable weather station

The LXH506 portable weather station is tailor-made for the photovoltaic industry, integrating high-precision solar total radiation sensors, temperature and humidity acquisition units, component temperature probes, wind speed and direction sensors, and pressure sensing modules, fully covering the core meteorological elements required for photovoltaic detection. Radiation sensors have excellent cosine response characteristics, stable measurement accuracy, and meet the metrological requirements for photovoltaic field acceptance and performance comparison. They can accurately capture real-time changes in light intensity; The temperature probe on the back panel of the module can closely adhere to the surface of the photovoltaic module, accurately restore the working temperature of the solar cell, and provide reliable basis for power correction and system efficiency calculation under STC standards. The entire sensing unit adopts standardized modular design, and can be expanded to include rain sensors and other components according to project requirements in the later stage, flexibly adapting to different project monitoring requirements, avoiding overall equipment replacement, and reducing long-term usage costs.

The biggest advantage of the equipment lies in its strong portability and rapid deployment capability. All sensors, data acquisition hosts, and aviation aluminum alloy telescopic tripods can be disassembled and stored in a portable protective box for single person transportation. The tripod does not require a concrete base and can be fully set up and debugged within 5 minutes, ready to use immediately. Whether it is site resource survey in the early stage of photovoltaic projects, short-term meteorological data collection in the feasibility study stage, distributed roof multi-point comparison monitoring, temporary comparison testing during power station completion acceptance, or synchronous collection of environmental data during fault diagnosis, LXH506 can be quickly put into use, filling the gap of fixed meteorological stations that cannot be moved for monitoring. The power supply mode is flexible and supports external DC power supply. In remote areas without mains power, small photovoltaic auxiliary power components can be used to achieve independent power supply, meeting the long-term continuous monitoring needs in the field.

The data collection host supports free setting of collection intervals and is compatible with two modes: short-term survey high-frequency sampling and long-term monitoring low-frequency recording. It has a large capacity local storage to ensure continuous data retention and has breakpoint resume function. After network interruption is restored, data will be automatically reissued to prevent data loss in outdoor environments. Supports RS485 communication interface, follows the universal Modbus protocol, and can upload real-time meteorological data to the photovoltaic monitoring platform, achieving linkage analysis between meteorological data and power generation data of the power station. By combining radiation and temperature data, operation and maintenance personnel can accurately distinguish between the decrease in power generation caused by weakened cloudy lighting and the power attenuation caused by component failures, reducing the need for ineffective equipment troubleshooting and greatly improving the efficiency of operation and maintenance diagnosis. The sensor of the whole machine has the ability to prevent dust and water, adapt to long-term outdoor deployment, resist sun exposure, rain, sand and dust erosion, and adapt to the on-site environment of photovoltaic projects in the vast majority of regions in China.

The refined operation and maintenance of the photovoltaic industry is continuously advancing, and the analysis of power generation and resource assessment based on meteorological data has become the industry standard workflow. The LXH506 portable meteorological station fills the gap in demand for mobile micro meteorological monitoring in the market, providing extensive services to new energy design institutes, EPC engineering companies, third-party testing agencies, and photovoltaic power station operation and maintenance enterprises. Suzhou LAILX continues to focus on the needs of photovoltaic scenarios, continuously optimizing sensor calibration algorithms, improving long-term measurement stability, and supporting complete data analysis software to facilitate users in exporting data and generating monitoring reports. In response to the future development trend of the photovoltaic industry, Lexus will continue to improve its environmental monitoring product system, promote data exchange between meteorological monitoring and IV detection, EL detection, and infrared thermal imaging detection equipment, create an integrated photovoltaic on-site detection solution, and assist in the digital and refined development of the entire process of photovoltaic project survey, acceptance, and operation.
