Description

Technical Field

[0001] The present invention relates to the technical field of photovoltaic power generation, and in particular to a fish-photovoltaic complementary photovoltaic power generation system. Background Art

[0002] "Fish-photovoltaic complementarity" refers to the combination of fish farming and photovoltaic power generation. A photovoltaic panel array is set up above the water surface of the fish pond, and fish and shrimp can be farmed in the water area below the photovoltaic panels. The photovoltaic array can also provide good shielding for fish farming, forming a new power generation model of "generating electricity above and farming fish below". This model reduces the occupation of land resources such as agricultural, industrial and residential land, and is conducive to improving the economic value of land.

[0003] Since most of the current fish-photovoltaic complementary power generation systems use fixed photovoltaic panels, although they can provide shade for fish farming, they will lead to insufficient light for aquatic organisms and affect their growth. For example, algae can produce oxygen, thereby ensuring the dissolved oxygen rate in the aquaculture water. If the growth of algae is affected, the lack of oxygen in the fish pond will inevitably affect the growth of fish and shrimp. Summary of the Invention
