Solar irradiance is the core basic parameter for calculating the power generation efficiency of photovoltaic modules, evaluating the performance of power stations, calibrating IV detection data, and accepting photovoltaic projects. The accuracy of irradiance detection directly determines the authenticity of photovoltaic data calculation and the scientificity of power station operation and maintenance plans. In scenarios such as on-site testing of photovoltaic power plants, component performance testing, scientific research experiments, and meteorological monitoring, traditional irradiance detection equipment generally suffers from problems such as bulky size, inconvenient portability, large temperature drift, weak anti-interference ability, and delayed data response. Especially in complex outdoor working conditions, temperature differences, light scattering, and environmental interference can easily lead to detection data deviation, which cannot meet the high-precision detection and calibration requirements. To overcome the pain points of industry metering, Jiangsu Jingwei relies on precision sensing technology and scene based research and development advantages to launch the JW-F04 portable irradiance meter. With the core advantages of high-precision sensing, fast response, ultimate portability, and all-weather stable operation, it has become the core equipment for accurate detection of light environment in the photovoltaic industry.

Accuracy is the core competitiveness of the JW-F04 portable irradiance meter. The equipment is equipped with an industrial grade A-level high-precision irradiance sensing chip, using imported optical filters and precision photosensitive elements, combined with self-developed temperature automatic compensation algorithm and linear calibration technology, completely solving problems such as temperature drift, light deviation, and data distortion in traditional equipment. The equipment can accurately detect the total irradiance of sunlight, with a wide measurement range and extremely high resolution. The data repeatability and stability far exceed industry standards. The detection data can be traced back to national measurement standards. Each device is equipped with a dedicated calibration report at the factory, providing authoritative and accurate data support for photovoltaic module power calibration, power station power generation performance evaluation, and scientific research data collection. Compared to ordinary metering devices, this product optimizes algorithms for outdoor scattered light, oblique light, and low light environments, accurately capturing radiation data in complex lighting environments and effectively avoiding detection errors caused by environmental factors.
In terms of structural design, the JW-F04 portable irradiance meter focuses on ultimate portability and adaptability for outdoor operations. The device adopts an integrated compact body design, with a small overall size and a weight of less than 500g. It is lightweight, easy to carry, and has no carrying burden. It can be easily placed in toolkits and operation toolboxes, perfectly adapting to outdoor mobile inspection and multi-point rapid detection needs. The device comes with an anti slip fixed back clip, which can be directly fixed on the frame, bracket, and other positions of the photovoltaic module. It can complete fixed-point long-term monitoring without manual holding, freeing up manpower and greatly improving the convenience of operation. At the same time, the sensor adopts a detachable protective structure and is equipped with a dust-proof and waterproof protective cover, which can effectively block the erosion of wind, dust, and rainwater. It is suitable for various outdoor work scenarios such as long-term outdoor monitoring and temporary sampling, and the durability of the equipment is significantly improved.
The equipment has the advantages of fast response and intelligent and efficient operation. It adopts a high-speed data acquisition module with millisecond response speed, which can capture changes in light intensity in real time, dynamically update irradiation data, and accurately adapt to the detection needs of outdoor light fluctuation scenes. Equipped with a high-definition LCD display screen and backlit display design, it can read clearly in both strong and low light environments. The operation interface is simple and intuitive, with one click power on for automatic calibration and detection, without the need for complex settings. Zero basic operators can quickly get started. Supporting real-time data display, peak locking, and automatic data storage functions, it can record multi-point detection data, facilitate on-site comparison and analysis by staff, and trace data in the later stage, effectively improving the professionalism and standardization of detection work.
In terms of battery life and environmental adaptability, the JW-F04 portable irradiance meter is fully compatible with outdoor all-weather work scenarios. The device adopts a low-power chip solution, paired with a long-lasting large capacity lithium battery, which is energy-saving and long-lasting. It can last for hundreds of hours on a single full charge, meeting the needs of long-term field inspections and fixed-point monitoring without frequent charging. The body adopts an industrial grade three proof design, which is dustproof, waterproof, anti vibration, and resistant to high and low temperatures. It can work stably in a wide temperature range of -30 ℃ to 70 ℃, and is not afraid of extreme outdoor conditions such as desert high temperature, high-altitude mountainous areas, and coastal humidity. It has strong environmental adaptability. At the same time, the device supports multi angle adaptive detection, which can flexibly adjust the sensing angle according to the installation angle of the photovoltaic module, accurately match the light receiving status of the module, and make the detection data more in line with the actual power generation conditions.
With excellent product performance, the JW-F04 portable irradiance meter is widely used in various fields such as photovoltaic power plant operation and maintenance testing, component IV testing data calibration, photovoltaic project completion acceptance, solar energy resource assessment, meteorological environment monitoring, and solar thermal research experiments. Whether it is the daily inspection and calibration of distributed household photovoltaics, large-scale ground power stations, solar energy resource data collection in research institutes, or standardized acceptance testing by third-party testing institutions, this equipment can efficiently handle it. With its advantages of precision, stability, portability, and durability, it has become a standard metering device in the industry.
Industry analysts point out that accurate irradiance data is the foundation for the refined operation and maintenance, scientific research and development, and standardized acceptance of the photovoltaic industry.
