Exclusive Interview with DBM: Digital New Energy Dialogue-Zhongjieda, Accurate Monitoring Enabling Efficient Operation of Photovoltaic Industry!

At the 18th SNEC International Solar Photovoltaic and Intelligent Energy Conference and Exhibition held recently, the Digital New Energy DataBM. Com interviewed Jia Shengjie, general manager of Beijing Zhongke Jida Technology Co., Ltd. In-depth understanding of how the company provides precise technical services for the photovoltaic industry through weather stations and resource radiation assessment systems .

Beijing Zhongke Jida Technology Co., Ltd. was founded in December 2014 by a doctor of Institute of Atmospheric Physics, Chinese Academy of Sciences. It is a company specializing in system integration and service of meteorological environmental protection and photovoltaic monitoring.

Compared with many links in the photovoltaic industry chain, solar radiation monitoring, photovoltaic resource assessment and nowcasting may not be well known to the public, but they are very important. It is an indispensable basic link in the planning, design, construction and operation of photovoltaic power plants , and also provides necessary support for power grid stability and power dispatching in the operation stage. It directly affects the power generation efficiency, return on investment and long-term stability of the power plant.

"Solar radiation intensity directly affects the power generation of photovoltaic panels, while the temperature change of module backplane will lead to fluctuations in power generation efficiency." Jia Shengjie introduced that the meteorological station system of China Science and Technology Da collects data such as solar radiation, temperature and humidity, wind speed and direction, and solar irradiance through real-time monitoring. It can help the photovoltaic power station to obtain the "required power generation" and "actual power generation" in real time, so as to provide data support for the operation and maintenance system of the photovoltaic power station and evaluate the operation efficiency of the project.

In addition, Jia Shengjie, general manager of China Science and Technology, also introduced that the company has formed a customized monitoring system for diversified application scenarios in the photovoltaic industry .

For example, in the field of distributed photovoltaic, the company provides lightweight weather stations for small projects such as roofs and industrial and commercial parks. To meet the requirements of accurate monitoring in the 100-meter area; for the large-scale photovoltaic power station of hundreds of megawatts in the northwest region, with the popularity of double-sided components, the scheme has been upgraded from the traditional total radiation and direct radiation monitoring to the detection function of scattered radiation.

"The back of the double-sided module can use scattered light to generate electricity, which requires a dedicated scattered radiation measurement device to be added to the equipment configuration." Jia Shengjie emphasized that for the monitoring of large-scale power plants, the company needs to collect multi-dimensional radiation data to help owners maximize the power generation potential of photovoltaic power plants.
