Jingwei JW-F04 portable irradiance meter for precise monitoring of irradiation assisted photovoltaic efficiency evaluation


The solar irradiance is the core natural factor that determines the photovoltaic power generation. Accurately mastering the illumination data is an important prerequisite for the site selection planning, power generation calculation, component performance testing, and system fault analysis of photovoltaic power plants. With the continuous improvement of refined management in the photovoltaic industry, the demand for portable and high-precision irradiance monitoring equipment in the market continues to grow. Jiangsu Jingwei Technology, in response to industry development trends, has developed and launched the JW-F04 portable irradiance meter. With high-precision sensing technology, comprehensive data acquisition capabilities, and user-friendly design, it provides professional solutions for light monitoring in the photovoltaic field, empowering scientific operation and management of photovoltaic projects.

The JW-F04 portable irradiance meter is specially designed for the photovoltaic industry, with a high-performance secondary standard spectral sensor at its core. Combined with multi-channel optical detection technology, it can synchronously collect multiple key data such as planar irradiation, total radiation, and scattered radiation, comprehensively restoring the on-site lighting environment and breaking the limitations of traditional single function irradiance meters with insufficient data dimensions. The device has fast response speed and real-time stable data output. Combined with self-developed environmental compensation algorithms, it can effectively offset measurement errors caused by temperature changes, lighting angle offsets, and spectral deviations. It can ensure accurate and reliable measurement results under different working conditions such as sunny and strong light, cloudy and cloudy days, and weak light in the morning and evening. By relying on detailed and accurate irradiation data, technicians can accurately evaluate component power generation efficiency, analyze system operation status, predict changes in power generation, and provide scientific basis for operation and maintenance decisions and equipment maintenance.


Portable and easy to operate are the core requirements of outdoor monitoring equipment. JW-F04 adopts a lightweight design in its external structure, with a simple and compact body, and a dedicated portable bag. It can be easily carried during outdoor inspections and on-site surveys, and a single person can independently complete all measurement work. The device abandons complex operation processes, with a high-definition display screen paired with a fully Chinese interface. Parameter settings are clear at a glance, and the layout of functional buttons is reasonable. Even first-time users can quickly familiarize themselves with the operation process. The device supports automatic data storage and real-time review. Data can be quickly imported into the computer through the USB interface. The supporting data analysis software can automatically generate data reports, draw light change curves, and achieve data visualization analysis, greatly simplifying the workflow of data organization, summary, and analysis in the later stage and improving overall work efficiency.


To adapt to the complex outdoor working environment of photovoltaics, the equipment comprehensively enhances its environmental adaptability and durability. The whole machine adopts a dust-proof and moisture-proof structure design, with outstanding protection level. It can operate normally in a wide temperature range of minus 20 degrees Celsius to 60 degrees Celsius. Facing common outdoor environments such as high temperature exposure, rainy and humid weather, and sandstorms, the equipment performance is always stable. Equipped with a large capacity rechargeable lithium battery, it has strong endurance and can meet uninterrupted field monitoring throughout the day. The low battery reminder function can promptly remind staff to replenish power and avoid equipment power outages during operation. At the same time, the equipment is equipped with intelligent self calibration function, which can regularly calibrate the accuracy of the sensors. Long term use can also maintain measurement accuracy, reduce maintenance costs, and extend the service life of the equipment.


Based on years of deep cultivation in the field of photovoltaic equipment, Jiangsu Jingwei Technology has always adhered to the original intention of quality. Every JW-F04 portable irradiance meter undergoes multiple rounds of precision testing, environmental simulation testing, and aging testing before leaving the factory, strictly controlling product quality. This device has a wide range of applications, including pre site selection survey and light resource evaluation for photovoltaic power plants, performance testing for component production, energy efficiency analysis in daily operation and maintenance of power plants, as well as meteorological monitoring, new energy research and other related fields. With excellent comprehensive performance, it has gained recognition and trust from a large number of industry customers.


The refined development of the photovoltaic industry relies on the support of various precision monitoring equipment. Against the backdrop of industry transformation and upgrading, Jiangsu Jingwei Technology will continue to focus on innovation in photovoltaic environmental monitoring and detection technology, continuously optimize the performance of the JW-F04 portable irradiance meter, enrich equipment functions, and enhance the level of intelligence. By providing precise products, reliable quality, and comprehensive services, we aim to assist major photovoltaic enterprises in achieving refined operations, improving power generation efficiency, and working hand in hand with industry partners to promote the sustainable development of the new energy industry and steadily advance the green and low-carbon cause.

Anchoring the true value of light energy, Jiangsu Jingwei JW-F04 portable irradiance meter establishes a solid foundation for photovoltaic detection data

Solar irradiance is the most fundamental environmental parameter in the photovoltaic industry. Component power calibration, IV curve STC standard conversion, site light resource assessment, power generation verification, and third-party testing report issuance are all based on accurate irradiance measurement. If there is a deviation in the irradiation data, all subsequent performance measurement results will be distorted, directly affecting the performance evaluation and revenue calculation results of the power station. Ordinary simple irradiation equipment on the market generally has shortcomings such as large temperature drift, insufficient spectral matching, and poor outdoor environmental stability. Large desktop irradiation instruments are inconvenient to carry and difficult to adapt to various distributed photovoltaic on-site mobile detection needs such as roofs and mountains. Jiangsu Jingwei JW-F04 portable irradiance meter, benchmarking against A-level measurement standards, balancing high precision and portability, has become the basic standard instrument for photovoltaic field testing, providing reliable light energy data support for…
