Combined with precise cosine correction, it can effectively eliminate angle errors and ensure measurement accuracy at different solar altitude angles. The data reliability reaches the industry standard level.


In terms of functional design, JW-F04 fully meets the requirements of photovoltaic full scenario applications. The instrument can independently measure total radiation and scattered radiation, and can also be used in conjunction with component planar probes to accurately measure the effective radiation received by the component, which can be directly used to calculate component conversion efficiency and system efficiency; Support multi-point mobile detection, fixed-point long-term monitoring, adapt to scenarios such as power station site selection survey, design verification, completion acceptance, operation and maintenance inspection, scientific research experiments, etc., and flexibly meet the data needs of different stages. Built in intelligent calibration algorithm, supporting one click calibration and automatic temperature compensation, effectively reducing the impact of environmental temperature changes on measurement accuracy and ensuring long-term stability.


Portability and ease of use are the prominent advantages of JW-F04. The whole machine adopts a lightweight integrated design, with small size and light weight, which can be carried by hand or in a portable case, and can be easily operated by a single person, especially suitable for outdoor mobile detection; The probe is designed to be separated from the host and can be flexibly arranged on the component plane or any measuring point, with convenient installation and strong adaptability. Equipped with a high-definition LCD display screen, it displays real-time measurement data, peak recording, temperature and other information. The interface is simple and intuitive, and the operation buttons are easy to understand, making it easy to get started without professional training.


Intelligent and data management capabilities enhance application efficiency. JW-F04 has built-in large capacity data storage, which can automatically record historical measurement data and support custom recording of time intervals to meet long-term monitoring needs; Equipped with USB data export and wireless transmission functions, data can be exported to a computer or uploaded to a cloud platform for easy data organization, trend analysis, and report generation; Equipped with professional analysis software, it can achieve functions such as data visualization, radiation resource evaluation, and power generation simulation calculation, providing data support for optimizing photovoltaic systems.


Strict environmental adaptability and reliability design. JW-F04 adopts industrial grade protective shell, which is dustproof, moisture-proof, and UV resistant. It can work stably in extreme temperature environments ranging from -30 ℃ to 70 ℃ and adapt to harsh outdoor conditions such as deserts, coasts, and high altitudes; The sensor has undergone strict screening and aging testing, with good stability, long lifespan, and long-term use without frequent calibration, reducing maintenance costs. The equipment complies with international and national standards such as IEC60904 and GB/T19565, and the measurement data can be used as a third-party measurement basis, with strong authority.
