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 various photovoltaic tests.

The core of JW-F04 portable irradiance meter adopts high-precision thermoelectric sensing elements, and the spectral response strictly matches the AM1.5 standard spectrum of photovoltaic cells, minimizing measurement errors caused by spectral mismatch. The device is equipped with an automatic temperature compensation algorithm, which can effectively suppress the problem of sensor temperature drift in high and low temperature environments. It can maintain stable and reliable measurement data even under complex outdoor conditions such as summer sun exposure, low temperature and high cold. The instrument can accurately collect the effective irradiance of the component plane, and together with the temperature sensing unit, synchronously obtain the temperature of the component backplane, providing complete environmental parameters for the standard condition conversion of IV testing, eliminating the testing interference caused by light fluctuations, and ensuring the performance testing of components at different time points. The results have horizontal comparison value and are an important supporting equipment for IV testing instruments and photovoltaic comprehensive detection systems.
The whole machine is fully designed for outdoor mobile inspection scenarios, and the shell has excellent protective performance, suitable for complex working environments such as outdoor dust and rain. The body is compact and lightweight, and the entire set of equipment is stored in a portable protective box. It is very convenient for a single person to carry and move around. Whether it is a large-scale photovoltaic power station on the ground, or a distributed project on the roof of a household or commercial building, it can quickly reach the measuring point to complete the sampling. The device is equipped with an outdoor high brightness display screen, which provides clear and intuitive readings under strong light. The operation logic is simple and easy to understand, and there is no need for complex professional training to get started using it. It supports both short-term on-site rapid sampling and long-term continuous recording mode, and can conduct site light resource survey to continuously collect the trend of radiation changes throughout the day, providing real light resource data reference for the early site selection and scheme design of new photovoltaic projects.
From the perspective of the entire industry chain, the JW-F04 portable irradiance meter covers multiple key links throughout the entire lifecycle of photovoltaic projects. In the early planning stage of the project, it is used for site light resource survey, collecting on-site irradiation data, assisting in the assessment of site power generation potential, and optimizing power station design schemes; During the construction and acceptance stage of the power station, in conjunction with IV performance testing, radiation and temperature data are synchronously collected to complete the standard conversion of component string performance, supporting completion acceptance and third-party testing work; During the operation and maintenance inspection phase, operation and maintenance personnel carry equipment with them to inspect the team, compare the measured irradiation values, verify the actual power generation of the power station, distinguish whether the decrease in power generation is caused by changes in lighting or component attenuation, and help operation and maintenance personnel accurately locate the problem; In component laboratory testing and product certification testing scenarios, it can also serve as an environmental monitoring device to ensure accurate and compliant collection of experimental environmental parameters. The instrument supports data storage and export, and can generate radiation change trend reports for easy data archiving, traceability, and report preparation, meeting the metrological compliance requirements of testing institutions.
The refined development of the photovoltaic industry relies on precise measurement of every basic parameter. Irradiance measurement may seem fundamental, but it directly determines the credibility of a large amount of testing work. Many on-site testing errors in the past were rooted in inaccurate collection of environmental light intensity. Jiangsu Jingwei JW-F04 portable irradiance meter solves the pain point of traditional equipment's inability to balance accuracy and portability, laying a solid data foundation for photovoltaic detection. With the continuous development of the domestic photovoltaic market, the demand for light resource assessment and on-site performance testing continues to grow, and the market demand for high-precision portable irradiation measurement equipment continues to be released. Jiangsu Jingwei continues to deepen its cultivation in the field of photovoltaic measurement and testing, focusing on polishing products based on real working conditions on the front line, continuously optimizing sensing and compensation algorithms, providing high reliability domestically produced measuring instruments for the industry, helping photovoltaic project surveying, testing, and operation work to be more scientific and accurate, and empowering the high-quality development of the new energy industry.
