Tongwei Co., Ltd. – Integration of Aquaculture and Photovoltaic Technologies for Sustainable Energy and Food Solutions
With increasing global demand for sustainable energy and food production, traditional agriculture and energy systems struggle to meet efficiency and environmental goals. Tongwei Co., Ltd. addresses these challenges by pioneering a unique business model that integrates aquaculture with photovoltaic (PV) technologies. Through its large-scale production of high-efficiency crystalline silicon solar cells and the development of fishery-solar hybrid PV power plants, the company contributes to both food security and renewable energy production. This integrated model helps reduce land usage, improve resource efficiency, and promote green energy while ensuring high-quality fish production for food supply chains.

The typical duration of implementing a fishery-solar integration project ranges from 12 to 24 months, depending on the scale and complexity of the installation.
Tongwei’s solutions are implemented in China, with significant projects across various provinces. The company is also expanding its fishery-solar hybrid model internationally, particularly in regions with high solar potential and demand for sustainable food production.
Tongwei is a global leader in both the aquaculture and photovoltaic industries, with vertically integrated operations that ensure control over the entire value chain—from high-purity crystalline silicon production to solar power generation. The company’s unique “fishery-solar integration” model reduces land use and environmental impact while enhancing the efficiency of both food and energy production. With an annual solar cell production capacity of 54 GW and plans to expand to 130-150 GW in the coming years, Tongwei has positioned itself as a major force in the global PV industry. Furthermore, its proven leadership in aquaculture makes it one of the largest feed producers in the world, supplying over 10 million tons of feed annually.
