From the perspective of existing demand, comprehensive land utilization is becoming increasingly stringent, and it is necessary to re-optimize the photovoltaic power station system to ensure agricultural (fishery) production output. Utility Model Content

[0006] An agricultural and fishery photovoltaic power station system, comprising:

[0007] A photovoltaic assembly, wherein the photovoltaic assembly is placed on the water surface through a photovoltaic bracket; an adjustable spectrum lamp is suspended from the lower side of the photovoltaic assembly; an image sensor is arranged on the side of the photovoltaic bracket, the optical axis of the image sensor is tilted downward and is used to collect images below the photovoltaic assembly; the adjustable spectrum lamp is connected in series with the inverter of the photovoltaic assembly through a control switch;
