In China, fishery-solar hybrid systems have grown dramatically in recent years. These hybrid system are straightforward: a solar array is installed above the fish pond’s water surface, and the water area beneath the solar array is used for fish and shrimp farming.
Fishery-solar hybrid systems come with several environmental and economic advantages, including the ability of the floating photovoltaic power station to effectively reduce the water temperature on hot summer days and shelter water surface from sunlight. This minimizes the outbreak of aquaculture diseases by impoving the water quality and adjusts the metabolism of fish to allow them to grow quickly. Moreover, the floating photovoltaic power system helps reduce water surface evaporation and loss. Another advantage is that these sort of systems allow more efficient land use by avoiding development on arable agicultural land.
