Irradiance is the core influencing factor of photovoltaic system power generation efficiency. Accurately measuring the total solar irradiance, scattered radiation, and effective irradiance of component planes is a key prerequisite for optimizing the design, efficiency evaluation, fault diagnosis, and power generation prediction of photovoltaic power plants. Traditional irradiance meters have problems such as low measurement accuracy, single functionality, poor environmental adaptability, and cumbersome data management, which make it difficult to meet the precise operation and maintenance needs of photovoltaic systems. Jiangsu Jingwei Technology Co., Ltd. is deeply engaged in the field of photovoltaic environmental monitoring and has innovatively developed the JW-F04 portable irradiance meter. With high-precision optical sensing, multi parameter synchronous measurement, strong environmental adaptability, and intelligent data management, it provides a precise and reliable "data ruler" for the assessment of photovoltaic system light energy resources, helping photovoltaic power plants achieve refined management and efficient power generation.

As a professional supplier of photovoltaic detection and environmental monitoring equipment, Jiangsu Jingwei has always focused on the demand for precise environmental data in the photovoltaic industry. Its core technical team has profound technical accumulation in optical sensing, signal processing, intelligent calibration and other fields. The JW-F04 portable irradiance meter launched this time is a new generation of high-precision light energy measurement equipment independently developed by the company based on years of photovoltaic project experience and customer feedback. It breaks through the technical bottleneck of traditional products, achieves multi parameter synchronous precise measurement, long-term stable outdoor operation, intelligent data management, and adapts to the environmental monitoring needs of photovoltaic power plants throughout their lifecycle.
High precision measurement technology ensures accurate and reliable data. JW-F04 adopts a secondary standard spectral response sensor to accurately match the spectral response characteristics of photovoltaic modules, avoiding measurement errors caused by spectral deviations. Equipped with a multi-channel optical detection module, it can synchronously measure five key parameters: total solar radiation, scattered radiation, reflected radiation, planar effective irradiance of photovoltaic modules, and environmental temperature, comprehensively capturing dynamic changes in solar energy resources data. The irradiance measurement range is 0-2000W/㎡, with an accuracy of ± 1W/㎡. The temperature measurement range is -40 ℃ to 80 ℃, with an accuracy of ± 0.5 ℃. The measurement data can be traced back to national metrology standards, ensuring the authority and reliability of the data. Built in intelligent calibration module, supports one click automatic calibration, eliminates the need for frequent factory returns, reduces usage costs, and extends equipment lifespan.
Portability and strong adaptability, suitable for outdoor operations in all scenarios. JW-F04 adopts a lightweight and compact design, with a total weight of only 450g and a small size that can be easily held with one hand. It is paired with a portable suitcase for easy carrying to any work site. The equipment adopts industrial grade protection design, with a dustproof and waterproof rating of IP67, and can adapt to harsh outdoor environments such as rain, snow, sand, and humidity. Adopting low-power design, equipped with 4 AAA batteries, with a battery life of up to 30 days, supporting long-term continuous outdoor monitoring; Simultaneously supporting external power supply, suitable for long-term fixed monitoring scenarios. Equipped with an adjustable bracket, the sensor angle can be flexibly adjusted to accurately match the installation angle of the photovoltaic module, ensuring that the measurement data truly reflects the component's light receiving situation.
Intelligent data management empowers refined operations and maintenance. JW-F04 has a built-in large capacity data storage module that can automatically store historical measurement data and support local data traceability and viewing. Equipped with a Bluetooth wireless communication module, it can wirelessly connect with mobile apps and PCs to achieve real-time transmission, remote viewing, and analysis of measurement data. The APP supports data visualization display, which can generate real-time data curves and historical trend charts, making it convenient for operation and maintenance personnel to intuitively grasp the changes in solar energy resources. Support one click data export, compatible with multiple formats such as Excel, CSV, etc., for easy data statistical analysis and report production; Simultaneously supporting cloud data synchronization and storage, achieving unified management and sharing of data across multiple devices. The device adopts low-power Bluetooth technology, with stable connection, low power consumption, and no impact on battery life.
Widely applied in multiple scenarios, the value runs through the entire photovoltaic industry chain. During the design phase of a photovoltaic power station, JW-F04 can accurately measure the solar energy resources data of the project location, providing core data support for power station site selection, component selection, and array layout optimization, enhancing the rationality of power station design and power generation potential; During the acceptance stage of the power station, irradiance and power generation can be measured synchronously to evaluate the actual power generation efficiency of the power station and identify design and construction issues; In the daily operation and maintenance stage, real-time monitoring of irradiance changes can be carried out to compare and analyze the difference between theoretical and actual power generation, quickly locate issues such as component obstruction, dust accumulation, and faults, and guide operation and maintenance personnel to operate accurately; In the fields of scientific research and teaching, it can be used for experiments such as solar energy resource research and photovoltaic module performance testing, providing accurate and reliable experimental data.
With excellent performance, JW-F04 has been applied in multiple photovoltaic power plants and research institutions in China. Users have provided accurate measurement data, strong stability, and convenient operation, which can effectively improve the precision level of photovoltaic power plant operation and maintenance, and help power plants improve their power generation efficiency by 5% -8%. The person in charge of Jiangsu Jingwei Technology Co., Ltd. stated that "solar energy resources are the 'energy source' of photovoltaic power plants, and accurate measurement is the foundation of efficient operation and maintenance. The launch of the JW-F04 portable irradiance meter fills the gap in high-precision portable irradiance measurement equipment in the domestic photovoltaic field. In the future, we will continue to optimize product performance, expand functional modules, provide more high-quality environmental monitoring equipment for the photovoltaic industry, and help promote the high-quality development of the photovoltaic industry. ”
