Photovoltaic irradiance, as a core environmental parameter that affects power generation, directly determines the rationality of power plant site selection, the scientificity of system design, and the accuracy of operation and maintenance decisions based on its measurement accuracy. Traditional irradiance meters have problems such as low measurement accuracy, single functionality, poor environmental adaptability, and insufficient portability, making it difficult to synchronously measure multidimensional light energy parameters and adapt to long-term monitoring needs in complex outdoor scenes. Jiangsu Jingwei R&D team closely focuses on industry pain points, integrates secondary standard spectral response sensors, multi-channel optical detection technology, and intelligent calibration algorithms, and launches the JW-F04 portable irradiance meter, achieving comprehensive upgrades in light energy measurement accuracy, functional integration, and scene adaptability.
High precision multi parameter measurement, accurately restoring the dynamics of light energy. The JW-F04 portable irradiance meter adopts a secondary standard spectral response sensor, which accurately matches the characteristics of the solar spectrum and effectively reduces measurement errors. The device is equipped with a multi-channel optical detection module, which can synchronously measure the total solar radiation, scattered radiation, reflected radiation, and effective irradiance of photovoltaic modules, comprehensively covering the required light energy parameters of the photovoltaic system and accurately capturing the dynamic changes of light energy resources. The measurement range covers 0-2000W/㎡, with an accuracy of ± 2%. It has excellent linearity and stability, and can provide accurate and reliable measurement data in both strong light direct and weak light scattering environments, providing a core basis for efficiency analysis and power generation prediction of photovoltaic systems.
Ultimate portability and strong environmental adaptability, suitable for all scenario monitoring needs. JW-F04 adopts a lightweight and compact design, with a total weight of only 450g. The compact body is matched with a portable buckle, which can be held, hung, and mounted on a bracket. It can be easily carried by a single person to various scenarios such as power plant site selection, rooftop components, desert photovoltaic bases, etc. The equipment adopts industrial grade protection design, with a sturdy and wear-resistant shell and a protection level of IP65. It can withstand harsh environments such as outdoor wind, rain, sand, high and low temperatures, and support long-term stable operation from -30 ℃ to 70 ℃. It is suitable for outdoor long-term unmanned monitoring. Equipped with a high contrast LCD display screen, it is clear and readable under strong light, supporting real-time data display and peak recording, making it easy to quickly view and record on site.
Intelligent calibration and data management enhance monitoring efficiency and data value. JW-F04 has a built-in intelligent calibration module that supports one click automatic calibration, effectively eliminating errors caused by environmental drift and sensor aging, and maintaining measurement accuracy for a long time. Integrated large capacity data storage module, can continuously store monitoring data for more than 1 year, supports dual data transmission methods of RS232 serial port and Bluetooth, can connect to computers and mobile phones for real-time data transmission, and achieve remote monitoring and data analysis. Equipped with professional data analysis software, supporting data export, curve drawing, and report generation, it can accurately analyze the distribution pattern of light energy resources, evaluate the actual light receiving efficiency of photovoltaic modules, and provide scientific support for optimizing power plant site selection, adjusting system parameters, and formulating operation and maintenance strategies.
With excellent performance and wide adaptability, the JW-F04 portable irradiance meter is deeply applied in the entire photovoltaic industry chain. During the site selection stage of the power station, it is used for the survey of solar energy resources, accurately evaluating the solar energy reserves in different regions, and providing data support for site selection decisions; In the system design phase, verify the rationality of the design scheme, optimize the installation angle and layout of components; During the operation and maintenance phase, real-time monitoring of irradiation data, comparative analysis of component power generation efficiency, timely detection of abnormal problems, and improvement of operation and maintenance refinement level.
