On September 4, the 11th Sichuan Agricultural Expo officially opened in Chengdu. Concurrently, the 11th Sino-German Agricultural Week was held at the Tianfu Agricultural Expo Park in Xinjin. As a flagship initiative for agricultural cooperation between China and Germany, the Sino-German Agricultural Week, serving as a dynamic platform for international exchange in agricultural technologies, resources, and talents, makes its debut in Sichuan. During the event, the Tongwei Fishery-PV Demonstration Park—located within the Xinjin Tianfu Agricultural Expo Park—drew significant attention from the visiting German delegation, who conducted on-site research and technical exchange.

The delegation, comprising officials from the German Federal Ministry of Food and Agriculture and representatives from the German Embassy in China, agricultural-related departments, and enterprises, toured the fields of Xinjin to experience firsthand the technological sophistication and vitality of Chengdu’s modern urban agriculture. At the demonstration park, Li Lunjia, General Manager of Chengdu Tongwei Automation Equipment Co., Ltd., and Qian Huazheng, Engineering & Technical Director of Tongwei New Energy, warmly welcomed the delegation. The visitors expressed strong interest in Tongwei’s facility-based aquaculture and PV solutions for power generation, gaining detailed insights into the equipment’s technical features and economic benefits.

German business representatives showed keen enthusiasm for Tongwei’s integrated PV industry chain.

The Tongwei PV-Fishery Demonstration Park, one of Tongwei's "integration of fishery and PV" industrial demonstration projects, is located in the core scenic area of Tianfu Agriculture Expo Island. Spanning 21 mu, the park exemplifies Tongwei’s commitment to sustainable urban agriculture, exhibition-driven economy, and the development of a green food consumption ecosystem. The demonstration park integrates Tongwei’s deep agricultural expertise with its cutting-edge new energy resources, creating a comprehensive and sustainable model of modern agriculture. It features famous, distinctive, premium, and safe aquatic product ecological farming, solar PV power generation, and science education tourism.

German business representatives learned about the development of the Tongwei PV industry.

The "integration of fishery and PV" demonstration center highlights Tongwei’s achievements in green development, smart aquaculture, and big data applications through interactive digital exhibition halls, multi-functional conference rooms, and a panoramic rooftop viewing platform. The center also serves as a hub for educational outreach, hosting over 8,300 participants annually in research and study programs. It actively promotes green, low-carbon, and environmentally friendly values to diverse social groups, including primary and secondary school students, contributing meaningfully to the public understanding of carbon neutrality.

Tongwei New Energy, the company’s dedicated green energy division, focuses on core innovations such as "integration of fishery and PV", source-grid-load-storage systems, virtual power plants, and carbon trading. It is building a full ecological chain for PV power—from source development and solution design to intelligent operations. To date, Tongwei has developed and constructed 56 PV power stations across more than 20 provinces, autonomous regions, and municipalities in China, with a cumulative installed and grid-connected capacity of 4.79 GW—most of which are based on the "integration of fishery and PV" model.
