Description

Technical Field

[0001] This invention relates to the field of photovoltaic power generation technology, and in particular to a solar-fishery complementary photovoltaic power generation system. Background Technology

[0002] "Fish-solar complementarity" refers to the combination of aquaculture and photovoltaic power generation. A photovoltaic panel array is installed above the fishpond surface, and fish and shrimp can be raised in the water below the photovoltaic panels. The photovoltaic array can also provide good shading for fish farming, forming a new power generation model of "power generation above and fish farming 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 solar-aquaculture hybrid power generation systems use fixed photovoltaic panels, although they can provide shade for fish farming, they can lead to insufficient light for aquatic organisms, affecting their growth. For example, algae can produce oxygen, thus ensuring the dissolved oxygen level in the aquaculture water. If the growth of algae is affected, then the lack of oxygen in the fishpond will inevitably affect the growth of fish and shrimp. Summary of the Invention
