Solar irradiance is the core basic parameter for calculating the power generation efficiency of photovoltaic modules, evaluating the production capacity of power stations, and calibrating detection data. The accuracy of irradiance measurement directly determines the authenticity and effectiveness of photovoltaic module performance testing, power station operation and maintenance judgment, and engineering acceptance results. Traditional irradiance meters suffer from issues such as insufficient accuracy, poor spectral matching, weak environmental adaptability, inconvenient portability, and cumbersome data management, which can easily lead to detection data deviations and affect the accuracy of photovoltaic power plant operation and maintenance decisions and capacity assessments. To solve the problem of precise radiation detection in the photovoltaic industry, Jiangsu Jingwei has launched the JW-F04 portable irradiance meter, which benchmarks against the international Class-A industry standard. With the core advantages of high precision, high adaptability, long battery life, and intelligence, it creates a standardized equipment for outdoor photovoltaic radiation detection.

Accuracy is the core advantage of the JW-F04 portable irradiance meter. The device's core sensor uses high-precision thermoelectric sensing elements, strictly matching the AM1.5 standard solar spectrum, with minimal spectral response error, fully complying with international photovoltaic detection standards. The device can accurately measure the total solar irradiance, with a wide measurement range, fast response speed, and strong data stability. It can capture subtle fluctuations in outdoor light intensity in real time. Even in complex meteorological environments such as cloudy, gentle winds, and uneven lighting, it can still output accurate, stable, and traceable detection data. The measurement accuracy far exceeds that of ordinary civilian lighting equipment and reaches industrial level detection standards. It can perfectly match harsh scenarios such as photovoltaic module IV testing data calibration, power plant capacity calculation, and scientific research experiment monitoring.
In terms of portability and scene adaptation, JW-F04 achieves ultimate optimization. The device adopts an integrated compact body design, with a compact size and a weight of less than 500g. The lightweight body has no carrying burden, and is equipped with anti slip back clips and dedicated portable storage bags. It can be easily fixed on the photovoltaic module frame and bracket, and can also be easily placed in the operation and maintenance tool kit. It is suitable for various operation modes such as outdoor mobile inspection, fixed-point monitoring, and batch testing. The equipment casing is made of aviation grade antioxidant material, which has been treated with wear-resistant, waterproof, and UV resistant aging processes. It is sturdy and durable, and can adapt to various outdoor harsh environments such as high temperature, low temperature, high humidity, and sandstorms. It operates stably all day long and has a longer service life. It is perfectly suitable for various photovoltaic power plant scenarios such as mountains, deserts, roofs, and water surfaces.
The battery life and data management system are fully adapted to the long-term outdoor operation needs. The JW-F04 is equipped with a large capacity rechargeable lithium battery and an intelligent power-saving control algorithm. When fully charged, it can achieve 24-hour uninterrupted continuous data acquisition. Its ultra long battery life can meet the needs of all day field batch testing and long-term fixed-point monitoring work, without the need for frequent charging, greatly improving work efficiency. The device comes with a large capacity local storage, which can store tens of thousands of sets of synchronized data on irradiance, environmental temperature, and detection time. It supports real-time data display, historical data query, and data curve tracing, comprehensively restoring the on-site lighting change pattern, and providing complete data support for photovoltaic module performance analysis and power plant capacity evaluation.
The intelligent data transmission and linkage function greatly upgrades the practicality of the device. JW-F04 supports USB wired and Bluetooth wireless dual-mode data transmission, which can quickly export detection data to computers and mobile devices. Equipped with professional PC data analysis software, it can automatically generate irradiation change curves, time period mean statistical reports, standardized monitoring reports, and efficiently organize, archive, and trace data. At the same time, the equipment can achieve data exchange and linkage with Jiangsu Jingwei JW-IV12 portable IV tester, synchronously matching irradiation data and component performance testing data, accurately completing STC standard operating condition data correction, greatly improving the overall accuracy of photovoltaic component performance testing and power plant efficiency evaluation, and forming an integrated photovoltaic testing solution.
With precise detection performance, ultimate portable experience, and comprehensive scene adaptation, Jiangsu Jingwei JW-F04 portable irradiance meter has been widely used in various fields such as photovoltaic power plant engineering acceptance, daily operation and maintenance monitoring, component performance calibration, new energy research experiments, meteorological environment monitoring, agricultural lighting analysis, etc., becoming an essential equipment for standardized testing and refined operation and maintenance in the photovoltaic industry. In the future, Jiangsu Jingwei will continue to deepen its cultivation in the fields of environmental testing and new energy monitoring, continuously optimize product accuracy and intelligence level, and provide more professional and reliable monitoring equipment for the industry.
