Solar irradiance is a core environmental parameter that determines the amount of photovoltaic power generation. Accurate measurement of irradiance data is a key foundation for the selection of photovoltaic power plant sites, system design, efficiency evaluation, and operation and maintenance optimization. Traditional irradiance meters have low accuracy and limited functionality, making it difficult to adapt to high-precision measurement requirements in complex outdoor environments; Imported equipment is expensive and complex to operate, which limits its widespread application in the industry. Jiangsu Jingwei Technology Co., Ltd. focuses on the pain points of photovoltaic light energy measurement and has ingeniously created the JW-F04 portable irradiance meter. With high-precision sensing technology, portable design, and intelligent functions, it provides professional level light energy measurement solutions for the photovoltaic industry and has become the "data cornerstone" for photovoltaic system efficiency evaluation.

JW-F04 is a high-precision environmental monitoring device developed specifically for photovoltaic system light energy measurement. The core sensing unit adopts a secondary standard spectral response sensor, matching the spectral response characteristics of photovoltaic cells to ensure a high correlation between measurement data and photovoltaic power generation efficiency. The device can synchronously and accurately measure four core parameters: total solar irradiance, scattered radiation, reflected radiation, and effective irradiance of photovoltaic modules. The measurement range covers 50~1400W/m ², with a resolution of 1W/m ² and a measurement accuracy controlled within * * ± (5%+5 digits) * *. The data accuracy meets the national second level standard and can meet the high-precision measurement needs of the photovoltaic industry. Compared to traditional simple irradiance meters, its measurement error is reduced by more than 60%, providing reliable data support for predicting photovoltaic power generation and calculating PR values.
The portability and ease of use design make JW-F04 suitable for outdoor measurement needs in all scenarios. The equipment adopts a lightweight integrated design, with a compact and lightweight whole machine that can be handheld and installed on a stand. It can be easily carried by a single person to any scene such as power plant site selection, rooftop distributed power plants, mountain photovoltaic projects, etc. Equipped with high-definition LCD display screen, real-time display of instantaneous irradiance, cumulative irradiance, environmental temperature and other data, simple and intuitive interface, Chinese operation menu, one click power on/off and data recording, beginners can quickly get started without training. Equipped with a large capacity lithium battery, it can be used continuously for more than 8 hours when fully charged. It supports both AC and DC power supply and is suitable for outdoor scenarios without mains power, ensuring long-term continuous measurement. Equipped with standard mounting brackets and horizontal calibration devices to ensure the sensor is installed horizontally and avoid installation errors affecting measurement accuracy.
Intelligent functional design significantly improves measurement efficiency and data value. JW-F04 has a built-in intelligent calibration module that supports on-site one click calibration, effectively offsetting measurement errors caused by environmental temperature, sensor aging, and other factors, ensuring long-term stable and reliable data. Equipped with automatic data recording and storage function, it can automatically collect and store data at set time intervals, support historical data query, export and printing, and facilitate subsequent data analysis and report generation. Equipped with RS485/232 wired communication and wireless transmission modules, it can be integrated with photovoltaic power station monitoring systems or cloud platforms to achieve real-time data upload, remote viewing, and abnormal warning, helping power stations achieve refined operation and maintenance. It can synchronously collect environmental temperature and humidity parameters, and analyze them in conjunction with irradiance data to accurately evaluate the impact of environmental factors on photovoltaic power generation efficiency.
From the perspective of application scenarios, JW-F04 runs through the entire photovoltaic industry chain and has become a core tool for multiple links. During the site selection stage of the power station, the distribution of radiation resources in different areas can be monitored for a long time to evaluate the quality of resources, provide scientific basis for the site selection and installed capacity design of the power station, and avoid insufficient project revenue due to resource evaluation errors; In the system design phase, the effective irradiance of component planes can be accurately measured, the installation angle and layout scheme of components can be optimized, the utilization rate of light energy can be maximized, and the system's power generation can be improved; During the operation and maintenance evaluation phase, regular monitoring of irradiance and power generation data can be conducted to calculate the power station's PR value, evaluate system operational efficiency, identify power generation decreases caused by abnormal irradiance, component attenuation, occlusion, and other issues, and guide operation and maintenance optimization; In the field of third-party testing and scientific research, its high-precision and traceable measurement data can serve as the core data support for photovoltaic system performance evaluation and technology research and development.
