Boonray Technologys intelligent photovoltaic inspection solution was unveiled at the China Electricity Council seminar, helping the industry reduce costs and increase efficiency.

The 2021 Photovoltaic Power Generation Operation Management and Industrial Development Innovation Exchange Seminar, hosted by the China Electricity Council, recently concluded. Representatives from companies such as State Power Investment Corporation, Huaneng Group, Huadian Corporation, Datang Group, CGN, and Boonray Technology were invited to jointly explore innovative development paths for the upstream and downstream photovoltaic industry in the context of carbon neutrality.

At the seminar, Boonray Technology released a promotional video for its latest intelligent photovoltaic inspection solution. This solution, developed with technologies such as multi-rotor drones, automated hangars, and intelligent vision algorithms, includes software systems independently developed by the Boonray team, including Boonray Zhifei, Boonray Jizhi, Boonray Xunneng, and Boonray Cloud Data Center.

     As the first year of the 14th Five-Year Plan, 2021 presents both opportunities and challenges for the photovoltaic industry. The opportunity lies in China's currently only approximately 270 GW of grid-connected photovoltaic power generation capacity. However, driven by the dual carbon goals, optimistic estimates suggest that my country's installed photovoltaic capacity could reach 2 GW by 2035. This massive demand for installed capacity suggests significant potential for the development of new energy. The challenge lies in the gradual phase-out of subsidies, with power generation becoming the key factor in measuring power plant profitability. PV operation and maintenance plays an increasingly important role in improving plant efficiency and reducing the cost per kilowatt-hour (LCOE). Centralized photovoltaic power plants cover vast areas, while distributed photovoltaic systems are increasingly pervasive. The post-operation and maintenance of photovoltaic products has traditionally relied on manual inspections, which are susceptible to terrain and other factors, resulting in extremely low efficiency. Furthermore, during inspections, equipment operating conditions are often assessed based on the experience of maintenance personnel, making comprehensive inspections difficult. Spot checks are often used, leading to significant bias in inspection results. Rising labor costs pose significant challenges to the sustainable development of the industry.

   Boonray Technology's intelligent photovoltaic inspection solution uses drones to collect infrared and visible light images of photovoltaic stations. It then employs image recognition algorithms to automatically identify component issues such as hot spots caused by bird droppings and obstructions caused by plants and flowers, streaks caused by diode damage, and component issues such as poor solder joints in junction boxes and open circuits causing no load. The system also intelligently analyzes the data to generate inspection reports and visualized data. The system can also connect to mobile devices to promptly push defect information to operators, forming a closed-loop business model. This system helps photovoltaic stations achieve digital, automated, and intelligent operation and maintenance, improve operational efficiency and power generation, and reduce operating costs and safety risks.

      This solution addresses inspection challenges faced by power plants with vast areas, rugged terrain, difficult manual access, and susceptibility to climate change. It can complete the imaging of all components at a 20MW site in a single day, achieving over 10 times the efficiency of manual inspections. Inspections that previously took over two months can now be completed in just one week, saving manpower and resources while reducing operational risks. This product is currently widely used in photovoltaic power plant inspections, land surveying, and other scenarios.

    Boonray Technology's long-standing focus on ubiquitous robotics has gradually demonstrated its advantages in key scenarios such as photovoltaics and mining. Ubiquitous robotics, the product of combining modular robotics with networking, represents a significant leap forward in traditional robotics R&D concepts, earning it the nickname "third-generation robotics." Compared to the research of individual robots, ubiquitous robotics focuses more on multi-robot collaboration and environmental intelligence.

      Taking mining as an example, Boonray Technology's "smart mining" solution can be divided into two parts: "aboveground" and "underground." Aboveground, drones are used to scan the entire mining area, creating a high-precision map using technologies like digital twins. This is then combined with a 5G network to transmit signals. Combined with the "aboveground" unmanned shovel-loading and dispatching system, this creates a smart ecosystem for the entire mining area, promoting the healthy and orderly development of the industry and contributing to the country's green and low-carbon transition.
