The power generation efficiency of photovoltaic power plants is closely related to solar irradiance, and accurate measurement of irradiance data is the core foundation for photovoltaic system design, power generation prediction, efficiency evaluation, and fault diagnosis. In the actual operation of photovoltaic power plants, deviations in irradiation data can lead to inaccurate power generation assessments and operational decision-making errors, directly affecting the investment returns of the power plant. Jiangsu Jingwei Technology Co., Ltd. is based on the refined development needs of the photovoltaic industry. With advanced optical sensing technology and precision manufacturing processes, we have independently developed the JW-F04 portable irradiance meter. With the advantages of high precision, portability, and intelligence, we provide professional solutions for solar energy measurement and environmental monitoring in photovoltaic power plants.

The solar irradiance is influenced by various factors such as time, season, weather, and geographical location, and has the characteristics of dynamic changes and uneven distribution. Traditional irradiance measurement equipment often has problems such as low accuracy, single functionality, poor portability, and weak environmental adaptability, which make it difficult to meet the precise measurement needs of outdoor, multi-point, and long-term photovoltaic power plants. The Jiangsu Jingwei R&D team focuses on industry pain points and innovatively uses secondary standard spectral response sensors and multi-channel optical detection technology to create this high-performance JW-F04 portable irradiance meter, which achieves synchronous and accurate measurement of total solar radiation, scattered radiation, reflected radiation, and effective irradiance of component planes, filling the market gap of portable high-precision irradiance measurement equipment.
The core advantage of JW-F04 portable irradiance meter lies in its ultra-high measurement accuracy and stable performance. The equipment adopts imported high-precision optical sensing elements, with a spectral response range that matches the spectral characteristics of photovoltaic modules. The measurement range is 0-1400W/m ², with a measurement accuracy of up to ± 2%. It can accurately capture dynamic changes in light energy resources, providing reliable data support for photovoltaic system efficiency analysis and power generation prediction. Whether it is sunny with strong light, cloudy with weak light, or low radiation conditions in the early morning and evening, the equipment can maintain stable measurement accuracy, with good data repeatability and high reliability, far exceeding the level of similar products in the industry. At the same time, the device has intelligent calibration function, supporting one click self calibration and regular calibration reminders, effectively avoiding measurement deviation caused by sensor aging and environmental interference, and ensuring stable accuracy for long-term use.
The portability and flexibility design enable JW-F04 to adapt to various complex photovoltaic scenarios. The equipment adopts a compact and lightweight design, with a small size and light weight. It is equipped with an anti slip handheld handle and a portable hanging rope. The operation and maintenance personnel can hold, hang, and fix it, making it easy to carry to various photovoltaic power plant scenarios such as mountains, roofs, deserts, and water surfaces. The device comes with an adjustable bracket that supports multi angle adjustment, which can accurately match the installation angle of photovoltaic modules, measure the effective irradiance of the module plane, and truly reflect the light energy intensity received by the module. At the same time, the device adopts a low-power design and is equipped with a large capacity lithium battery. It can work continuously for more than 72 hours when fully charged, supporting long-term and uninterrupted outdoor monitoring without frequent charging, greatly improving outdoor work efficiency.
Intelligent and data management functions assist in the refined operation and maintenance of photovoltaic power plants. The JW-F04 portable irradiance meter is equipped with a high-definition LCD display screen, which can display real-time parameters such as instantaneous irradiance, cumulative irradiance, ambient temperature, measurement time, etc. The data is clear and intuitive, making it easy to view and record in real-time on site. The device is equipped with an intelligent data acquisition system that supports automatic data storage, USB one click export, and cloud data synchronization. It can record historical irradiation data, generate daily, weekly, and monthly irradiation change curves, facilitate operation and maintenance personnel to analyze the distribution pattern of light energy resources, evaluate the power generation efficiency of photovoltaic systems, and troubleshoot power generation fluctuations caused by abnormal irradiation. In addition, the device has the function of expanding environmental parameter monitoring, which can be matched with temperature and humidity sensors to synchronously monitor environmental temperature and humidity, providing data support for temperature compensation and environmental adaptability analysis of photovoltaic modules.
With excellent performance and reliable quality, the JW-F04 portable irradiance meter has been widely used in various aspects of photovoltaic power plant site selection survey, system design verification, pre grid acceptance, daily operation and maintenance monitoring, power generation evaluation, fault diagnosis, etc. During the site selection stage of the power station, accurate measurement of regional solar energy resources can be carried out to provide a basis for the layout design of the power station; During the operation and maintenance phase, real-time monitoring of irradiation data can be conducted to compare theoretical and actual power generation, and quickly locate issues such as component obstruction, attenuation, and faults; In the field of scientific research, it can be used for performance testing of photovoltaic modules, research on solar energy resources, and other scenarios. At present, the device has been successfully applied in multiple photovoltaic projects in China. With accurate measurement data, convenient operation experience, and stable performance, it has gained widespread recognition and praise from customers.
