Jiangsu Jingwei Technology, as a leading enterprise in the field of new energy monitoring equipment in China, focuses on the research and development, production, and sales of photovoltaic environmental monitoring, energy metering, and other related equipment. It has a complete research and development system, advanced production equipment, and strict quality control system. The company relies on core capabilities such as online energy measurement technology research and development, emerging energy technology research and development, and focuses on the pain points of environmental monitoring in photovoltaic power plants. For precise measurement scenarios of solar irradiance, it integrates secondary standard spectral response sensors, multi-channel optical detection technology, and intelligent calibration technology to successfully develop the JW-F04 portable irradiance meter, providing high-precision and high reliability light energy measurement equipment for the photovoltaic industry.
The core advantage of JW-F04 portable irradiance meter lies in its high-precision measurement capability, which fully meets the stringent measurement standards of the photovoltaic industry. The equipment adopts a secondary standard spectral response sensor, with a spectral response range that matches the solar radiation spectrum, achieving industry-leading accuracy. It can synchronously measure the total solar radiation, scattered radiation, reflected radiation, and effective irradiance of photovoltaic modules, accurately capturing dynamic changes in solar energy resources. The measurement range covers 0-2000W/㎡, with a resolution of up to 1W/㎡ and a measurement error of ≤± 2%. It has excellent linearity and stability, and can accurately capture subtle changes in light intensity, providing reliable data support for the calculation of photovoltaic power generation and system efficiency evaluation. At the same time, the device is equipped with an intelligent calibration module that supports dual modes of automatic and manual calibration. It can effectively eliminate measurement errors caused by changes in environmental temperature and humidity, as well as sensor aging, ensuring stable long-term measurement accuracy without the need for frequent factory calibration and reducing usage costs.
Portability and environmental adaptability design enable JW-F04 to adapt to various complex outdoor scenarios, achieving flexible deployment and long-term monitoring. The equipment adopts a lightweight and compact design, with a small overall volume and light weight, making it easy to carry to any position of the photovoltaic power station for multi-point measurement, and easily meeting the measurement needs of complex terrain power stations such as mountains, water surfaces, and deserts. The enclosure is made of industrial grade high-strength materials, with dust-proof, waterproof, anti-corrosion and anti-aging characteristics. The protection level reaches IP65, and it can operate stably for a long time in harsh environments such as -20 ℃ to 60 ℃ wide temperature, high humidity, wind and sand. It is not afraid of outdoor extreme weather tests. The device is equipped with a high brightness LCD display screen, which is clear and readable under strong light. It supports real-time data display, historical data query,

In addition, the device is equipped with a large capacity lithium battery with a battery life of over 7 days, supporting long-term unmanned outdoor monitoring. It is also equipped with a solar charging interface, which can be self charged using photovoltaic modules, solving the problem of long-term power supply in the wild.
Intelligent functions and data transmission capabilities assist in the digitization and efficiency of photovoltaic operation and maintenance. JW-F04 is equipped with a high-precision data acquisition and storage module, which can collect and store irradiance data in real time. It supports recording at multiple time intervals such as 1 minute, 5 minutes, and 10 minutes, and can store data locally for more than 10 years, meeting long-term data traceability needs. The device supports multiple data transmission methods such as RS485, WIFI, Bluetooth, etc., and can seamlessly integrate with photovoltaic power station monitoring platforms and data collectors to achieve real-time data uploading, remote monitoring, and analysis, making it convenient for backend management personnel to grasp the real-time status of the power station's lighting resources and accurately evaluate the system's power generation efficiency. Equipped with professional data analysis software, it can perform statistical analysis, trend drawing, and report generation on the collected irradiance data. Combined with component temperature, power generation, and other data, it can accurately calculate PR values and system efficiency, providing scientific basis for power plant operation and maintenance optimization, fault diagnosis, and power generation prediction. At the same time, the equipment has a data abnormality alarm function. When the irradiance data exceeds the normal range or the equipment malfunctions, an alarm message can be sent in a timely manner to remind the operation and maintenance personnel to handle it in a timely manner, ensuring the continuity of monitoring work.
In practical applications, the JW-F04 portable irradiance meter, with its powerful performance, is widely applicable to key links throughout the entire lifecycle of photovoltaic power plants. During the site selection stage of the power station, the distribution of solar energy resources in candidate areas can be accurately measured, the degree of resource abundance can be evaluated, and scientific basis can be provided for the site selection of the power station; In the system design phase, accurate irradiance data can be provided to optimize component layout, tilt angle design, inverter selection, and improve system power generation efficiency; During the acceptance stage of the power station, it can be verified that the actual radiation received by the components is consistent with the design values, and the construction quality of the power station can be evaluated; During the operation and maintenance phase, long-term monitoring of changes in lighting resources can be carried out, combined with power generation data, to accurately diagnose issues such as component obstruction, attenuation, and faults, optimize operation and maintenance strategies, and enhance the overall revenue of the power station. In addition, the equipment can also be applied to scenarios such as solar energy research experiments, agricultural photovoltaics, and integrated building photovoltaics, meeting the needs of multiple fields of light energy measurement.
