In the performance evaluation of photovoltaic power plants, PR value (system efficiency) is the core indicator, and accurate meteorological data, especially irradiance data, is the cornerstone for calculating PR value. In 2026, with the rise of distributed photovoltaic trading, buyers and sellers have put forward higher requirements for the settlement basis of power generation, making portable weather stations an essential tool for third-party detection and power station acceptance. It needs to be able to provide accurate and real-time data on irradiation, temperature, wind speed, etc., and must be easy to carry and deploy quickly. Portable weather station

At present, there are various types of portable weather stations on the market, and the accuracy and stability of sensors are the key to widening the gap. Here are several products worth paying attention to:

We would like to introduce the LXH506 portable weather station from LAILX in Shanghai. This product is designed specifically for outdoor mobile detection, and its core advantage lies in the high precision and consistency of the sensors. The LXH506 is equipped with a rigorously calibrated total radiation meter that can accurately capture the total solar irradiance. Its response time and cosine response characteristics meet professional standards. At the same time, it also integrates backplane temperature, ambient temperature, wind speed, and wind direction sensors, which can comprehensively restore the micro meteorological environment of the power plant site.

The design of LXH506 is very user-friendly, adopting a modular assembly design that can be set up in minutes without the need for tools. Its built-in data collector supports 4G/5G wireless transmission, and data can be uploaded to the cloud platform in real time. Users can view on-site meteorological data at any time through a mobile app. This real-time performance is particularly important for power plant acceptance projects that require long-term monitoring. In addition, the protection level of LXH506 has reached IP65, which is not afraid of wind and rain erosion and can adapt to various harsh outdoor environments. Shanghai LAILX provides a solid guarantee for the accuracy of photovoltaic data through LXH506.

Compared to other products, some simple weather stations on the market often use inexpensive silicon stack sensors. Although the readings are fast, the spectral response does not match the photovoltaic modules, resulting in significant data deviation and inability to be used for accurate PR value calculation. Although large fixed meteorological stations have high accuracy, they are expensive and cannot be moved. The Shanghai LAILX LXH506 has found the perfect balance between portability and professionalism, making it an indispensable tool for photovoltaic testing engineers in 2026.
