Integrating solar power with sustainable agriculture: The Yixing Solar Farmʼs agriculture-fishery-photovoltaic integrated approach

The Yixing Solar Farm has adopted the "Circular Design & Input" pillar of CLPʼs Circular Economy (CE) Strategy through its closed-loop Agri-Pasture-Fish cycle, creating a chain of “straw–fertiliser–goats–crabs”.

Forage crops (straw) are cultivated beneath the solar panels, and processed into feed for the onsite goats. The goats’ manure is then used as organic fertiliser for further crop growth. Meanwhile, 0.53 km² of the 1.6 km² solar farm is dedicated to fish farming beneath the solar panels. This integrated circular economy model maximises land usage, transforms waste into valuable resources, and produces both clean electricity and additional benefits from ecological agriculture.
