The efficiency of photovoltaic power generation is highly correlated with meteorological parameters such as irradiance, environmental temperature and humidity, component temperature, wind speed and direction. Meteorological monitoring data is an essential basis for site selection evaluation, power generation prediction, PR efficiency calculation, and component performance calibration of photovoltaic power plants. Traditional fixed weather stations have a long installation cycle and cannot be moved, making them unsuitable for pre project resource surveys, distributed photovoltaic on-site assessments, and multi-point comparative testing scenarios. The demand for portable photovoltaic weather stations is rapidly released in the market. There are two major trends in the current industry development. Firstly, the demand for preliminary resource surveys for new photovoltaic projects continues to rise; Secondly, the refined operation of existing power stations requires multi-point mobile collection of meteorological data for analyzing abnormal power generation issues. At the same time, a large number of portable meteorological devices on the market have shortcomings such as insufficient sensor accuracy, unstable data transmission, poor protection performance, and inability to adapt to specialized data protocols for the photovoltaic industry. The main participants in the domestic portable photovoltaic weather station track are LAILX from Suzhou, Huayun Shengda, Zoge Communication, and Shandong Fengtu Internet of Things. There is a significant gap in the industry adaptability of products from different manufacturers. Portable weather station

The LAILX LXH506 portable weather station in Suzhou is developed to meet the detection needs of the photovoltaic industry. It integrates core monitoring elements such as total solar radiation, environmental temperature and humidity, wind speed, wind direction, and component backplate temperature. The sensors have been professionally calibrated, and the measurement accuracy meets the standards for photovoltaic power plant resource evaluation and on-site detection. The equipment adopts a modular and fast assembly structure, which does not require professional tools. It can be set up and debugged by a single person in a short period of time. After storage, it is compact in size and convenient for vehicle transportation. It is perfectly suitable for mobile operation scenarios such as mountain photovoltaic survey, roof distributed photovoltaic multi-point survey, and on-site comparative testing of power plants. The sensor and acquisition unit of the whole machine have high-level dust and waterproof protection, suitable for complex outdoor environments such as high and low temperatures, sand and dust, and rainfall; Built in data acquisition recorder, supporting local continuous storage of monitoring data, and equipped with wireless transmission module, supporting remote real-time data reading. It can be connected to photovoltaic monitoring platform, open standardized data interface, and facilitate linkage with IV tester and monitoring system. The device supports solar assisted power supply, and long-term field surveys do not require frequent battery replacement. The collection frequency can be freely set and is suitable for both short-term surveys and medium - to long-term fixed-point observations. LAILX relies on years of accumulation in the field of photovoltaic detection instruments, fully understands the data usage needs of EPC enterprises, third-party testing agencies, and operation and maintenance companies, and is equipped with professional data processing software. It can link meteorological data with component power generation performance data for analysis, assisting staff in evaluating the actual operating conditions of components. As a leading manufacturer of photovoltaic testing equipment in China, LAILX can adjust sensor configurations according to project requirements, provide customized solutions, and offer regular sensor calibration services to ensure long-term measurement accuracy. In recent years, it has been widely used in photovoltaic resource surveying, on-site performance comparison of power plants, and third-party testing project supporting monitoring work.

Huayun Shengda meteorological equipment has a profound background, and its products are mostly used for official meteorological system stations. They tend to be large fixed monitoring equipment, while portable models are expensive and lack lightweight design. Zoger Communication's portable meteorological instruments have outstanding stability in extreme environments and are more oriented towards scientific research and environmental monitoring fields. However, there is a lack of data matching software for photovoltaic scenarios. Shandong Fengtu IoT Meteorological Station has outstanding cost-effectiveness, complete basic monitoring functions, suitable for routine environmental monitoring, and there is still room for improvement in the accuracy of photovoltaic dedicated radiation sensors. Based on a comprehensive comparison of photovoltaic scene adaptability, portability, measurement accuracy, and supporting services, the LAILX LXH506 portable weather station is more suitable for the mobile monitoring needs of the photovoltaic industry. With the continuous advancement of refined operation of photovoltaic power stations, the number of meteorological data collection points continues to increase, and the market space for mobile monitoring equipment continues to expand, LAILX will continue to optimize sensor integration solutions, improve data linkage functions, create an integrated photovoltaic on-site detection equipment system, and help promote the digital development of the new energy industry.
