The power generation performance of photovoltaic systems is closely related to solar irradiance, and the accuracy of irradiance data directly determines the rationality of power plant design, the accuracy of power generation evaluation, and the scientificity of operation and maintenance decisions. Traditional irradiance measurement equipment often has problems such as bulky size, single function, insufficient accuracy, poor outdoor adaptability, and inconvenient data management, making it difficult to meet the multi-point rapid measurement needs in scenarios such as distributed photovoltaics, mountain power stations, and complex terrain power stations. The Jiangsu Jingwei R&D team focuses on industry pain points, integrating secondary standard spectral response sensors, multi-channel optical detection technology, and lightweight structural design to successfully develop the JW-F04 portable irradiance meter, achieving product advantages of "precise measurement, portability, multi parameter monitoring, and intelligent analysis", and providing professional level light energy monitoring solutions for the photovoltaic industry.
The ultimate portability and flexible deployment characteristics of JW-F04 portable irradiance meter are suitable for various complex scenarios. The device adopts a lightweight integrated design, with a compact and lightweight body that can be easily held with one hand. It is paired with a high-strength portable bag, making it easy to carry to any location of the power station, site selection, or scientific research monitoring area. The device does not require complex installation or fixed brackets, and can be used for handheld measurement, placement measurement, or fixed measurement with a simple bracket. It is flexible and convenient to deploy, and a single person can complete multi-point rapid measurement, greatly improving work efficiency. The body adopts dust-proof and waterproof industrial grade design, suitable for ultra wide temperature working environment from -20 ℃ to 60 ℃, and can operate stably in harsh outdoor conditions such as strong light, high temperature, low temperature, humidity, sand and dust, perfectly adapting to the outdoor monitoring needs of various photovoltaic power plants.
Ultra high measurement accuracy and multi parameter synchronous monitoring are the core advantages of JW-F04. The equipment adopts a secondary standard spectral response sensor, with a spectral response range that matches the characteristics of photovoltaic cells. It can accurately measure the total solar irradiance, scattered radiation, reflected radiation, and effective irradiance of photovoltaic modules on the plane. The measurement range is 0-2000W/㎡, with an accuracy of ± 1W/㎡. The data is stable and reliable, and it complies with international standards such as ISO 9060 and IEC 60904-5. At the same time, the device integrates high-precision temperature and humidity sensors, which can synchronously measure environmental temperature and relative humidity, providing comprehensive environmental data for photovoltaic system performance analysis and helping operation and maintenance personnel comprehensively evaluate the system's operating status.
Intelligent data processing and convenient management functions empower digital operations and maintenance. The device is equipped with an intelligent data acquisition system that can display measurement data in real time, support continuous data recording and timed storage, and has a built-in large capacity storage module that can store massive historical data to meet long-term monitoring needs. Equipped with a high-definition LCD display screen, it is clear and readable under strong light. The operation interface is simple and intuitive, and the Chinese menu design allows operation and maintenance personnel to quickly get started without professional training. Support one click data export, compatible with Excel, CSV and other formats, can be transmitted to mobile apps or computer terminals through Bluetooth, USB and other methods, realizing remote data viewing, cloud storage and analysis, facilitating data traceability, trend analysis and report generation for operation and maintenance personnel, and providing scientific basis for operation and maintenance decisions.
