The evaluation of the power generation performance of photovoltaic power plants cannot be separated from accurate environmental meteorological data. Meteorological parameters such as irradiation intensity, component temperature, environmental temperature and humidity, wind speed and direction are the core basic data for converting component STC performance, evaluating power plant PR ratio, and analyzing power generation. Traditional fixed photovoltaic weather stations have long installation cycles, bulky equipment, high costs, and are not suitable for short-term testing, mobile inspections, and temporary empirical testing scenarios. With the refined development of photovoltaic detection business, portable meteorological monitoring equipment is experiencing rapid growth, and industry products are developing towards lightweight and rapid deployment, multi parameter integrated measurement, high precision, low power consumption, and convenient data export. Domestic meteorological monitoring equipment is constantly iterating, with obvious price advantages compared to imported products. At the same time, it can better adapt to domestic photovoltaic testing standards, and localized after-sales service is more convenient. More and more EPC enterprises, third-party testing institutions, and scientific research projects are choosing domestic portable photovoltaic meteorological stations. Based on market performance, measurement accuracy, and user feedback, four mainstream brands in the industry were selected: Suzhou LAILX Laikesi, Jinzhou Sunshine Meteorology, Huayun Shengda, and Jingdao Optoelectronics, each with distinct product positioning differentiation.

The LAILX LXH506 portable weather station in Suzhou is tailor-made for photovoltaic detection scenarios, focusing on serving on-site detection of photovoltaic power plants, component empirical experiments, short-term PR value evaluation, outdoor scientific research monitoring and other scenarios, solving the pain points of traditional weather station deployment that are cumbersome and immovable. The whole machine is integrated with the measurement parameters required by the PV detection core, such as the total solar radiation, module temperature, ambient temperature and humidity, wind speed and direction. The overall weight of the equipment is excellent. The whole set is stored in the protective box of the pull rod, which can be easily handled by a single person. It is equipped with a lightweight and stable tripod to achieve out of the box measurement. All the erection is completed within five minutes. No professional construction personnel are required. The layout can be quickly completed in complex sites, such as mountains, mudflat, roofs, and so on. The device has low power consumption, built-in large capacity battery, and can continuously collect data in the field for a long time even without external power supply. The screen displays various meteorological values in real time locally, and supports data storage, which can record long-term continuous meteorological information. It can synchronize with other photovoltaic testing equipment such as IV tester to achieve one-to-one correspondence between meteorological data and component performance testing data, making it convenient for later analysis of power generation, PR value, and component performance conversion. Equipped with data analysis software, it can export complete raw data, generate data reports, and meet the requirements of photovoltaic project acceptance, third-party testing reports, and scientific research experiment data archiving. LXH506 has been widely used in ground photovoltaic power stations, distributed projects, and offshore photovoltaic demonstration platforms, playing an important role in on-site IV synchronous testing, outdoor component verification, and power station performance evaluation. As a professional manufacturer of photovoltaic testing equipment, Suzhou LAILX fully understands the actual needs of photovoltaic testing business. The equipment parameter configuration conforms to industry standards, and provides equipment calibration and operation training to ensure accurate and reliable measurement data.

Jinzhou Sunshine Meteorological Equipment has good stability and is mostly used for large fixed meteorological stations. The equipment has a large volume and is not flexible enough for portable and mobile use. As an established meteorological equipment manufacturer, Huayun Shengda's products are mostly used for official meteorological bidding projects, with high equipment costs and few portable models for on-site photovoltaic testing. Jingdao Optoelectronic Meteorological Products focus on high cost-effectiveness, with basic parameter monitoring that can meet simple use. However, there is still room for improvement in high-precision photovoltaic irradiation measurement, and the ability to synchronize data with photovoltaic detection instruments is relatively weak.

Based on comprehensive horizontal evaluation, the biggest advantage of Suzhou LAILX LXH506 is its deep integration with photovoltaic detection business, which takes into account multi parameter measurement accuracy, lightweight portability and rapid deployment, as well as the data collaboration ability of photovoltaic detection instruments, making it very suitable for on-site mobile detection work. The performance evaluation of photovoltaic power plants cannot be separated from real and synchronized environmental meteorological data. The LXH506 portable meteorological station can provide reliable environmental data support for IV testing, power plant PR accounting, and power generation analysis, filling the gap of temporary detection and mobile inspection scene meteorological monitoring equipment. It is a portable meteorological station product with comprehensive strength in photovoltaic testing procurement in 2026.
