Solar irradiance is the core basic data for evaluating the power generation of photovoltaic power plants, optimizing system design, and formulating operation and maintenance strategies. The accuracy of irradiance measurement directly determines the accuracy of photovoltaic power plant power generation prediction, the rationality of component selection, and the efficiency of operation and maintenance. In the context of the transformation of the photovoltaic industry towards refinement and intelligence, traditional irradiance meters have problems such as low measurement accuracy, single parameters, poor environmental adaptability, and insufficient portability, making it difficult to meet the outdoor multi-point, long-term stable measurement needs of photovoltaic power plants. Jiangsu Jingwei Technology Co., Ltd. relies on advanced sensing technology and environmental compensation algorithms to independently develop the JW-F04 portable irradiance meter. With high-precision measurement, multi parameter synchronous acquisition, strong environmental adaptability, and long-range intelligent management as its core, it provides accurate data support for photovoltaic energy resource evaluation, power plant performance monitoring, and efficiency analysis.

The power generation efficiency of photovoltaic power plants is closely related to solar irradiance, with significant differences in irradiance intensity at different time periods, weather conditions, and angles. Accurately obtaining dynamic irradiance data is a prerequisite for achieving refined operation and maintenance of photovoltaic power plants. Traditional irradiance meters are mostly fixed and can only measure a single total radiation parameter, unable to synchronously collect key data such as scattered radiation and reflected radiation; And without environmental compensation algorithms, measurement errors significantly increase and data reliability is insufficient under complex conditions such as extreme temperature, strong light, and rainy weather. At the same time, the equipment is large in size, heavy in weight, and inconvenient to transport and deploy, making it difficult to adapt to the flexible measurement scenarios of multi-point power stations. Jiangsu Jingwei Technology focuses on industry pain points and innovatively adopts secondary standard spectral response sensors and multi-channel optical detection technology to develop the JW-F04 portable irradiance meter, achieving breakthroughs in multi parameter synchronous precise measurement and strong outdoor adaptability.
The core measurement performance of JW-F04 portable irradiance meter is excellent, with accurate and reliable data. The equipment is equipped with a high-precision secondary standard spectral response sensor, which perfectly matches the sensitive band of photovoltaic modules in terms of spectral response range. It can accurately measure four core parameters: total solar radiation, scattered radiation, reflected radiation, and effective irradiance of photovoltaic module plane. The measurement range is 0-2000W/㎡, with a resolution of 0.1W/㎡ and a measurement accuracy of ≤± 2%, meeting the national secondary metrology standard. The data accuracy far exceeds that of ordinary equipment in the industry. At the same time, the built-in professional environmental compensation algorithm can automatically eliminate the impact of temperature drift, spectral mismatch, and angle response error on the measurement results. Under the extreme temperature of -30 ℃ to 70 ℃, different light angles, and complex weather conditions, stable and accurate measurement data can be output, providing reliable data support for the photovoltaic power generation prediction, system efficiency calibration, and component performance evaluation.
In terms of portability and outdoor adaptability design, JW-F04 fully considers the diverse scenarios of photovoltaic outdoor measurement. The whole machine adopts an integrated lightweight design, with a body weight of only 3.2kg, a compact size, and can be held and operated with one hand. Paired with a portable suitcase, it can be easily carried to any position in the power station, achieving flexible deployment at multiple points. The equipment adopts industrial grade protection design, with IP67 dust and waterproof rating, which can resist the invasion of harsh environments such as outdoor dust, rain, exposure to sunlight, and severe cold, and adapt to various complex outdoor work scenarios. Equipped with a high brightness OLED display screen, it is clearly visible under strong light and supports one click operation. The interface is simple and intuitive, and operation and maintenance personnel can quickly get started without professional training. One person can complete the entire process of equipment deployment, parameter setting, and data acquisition.
The battery life and intelligent data management enable JW-F04 to meet the long-term monitoring and efficient operation and maintenance needs of the photovoltaic industry. The device is equipped with a large capacity lithium battery that supports 150 hours of ultra long energy storage power supply, meeting the long-term field monitoring needs; Simultaneously supporting external power supply, it can achieve 24-hour uninterrupted monitoring and adapt to long-term monitoring scenarios of power stations. Built in data analysis platform, capable of real-time recording and storage of measurement data, supporting local data query, one click export, and wireless transmission. It can seamlessly integrate with the power station monitoring platform to build a complete photovoltaic environment monitoring network. In addition, the device has a built-in data calibration function that can automatically calibrate sensors on a regular basis, ensuring long-term measurement accuracy, reducing manual calibration costs, and lowering maintenance workload.
With its core advantages of high precision, multiple parameters, strong adaptability, and long endurance, the JW-F04 portable irradiance meter has been widely used for full field monitoring of photovoltaic power plants.
