Abstract: In order to reduce the fuel consumption, environmental pollution and power generation costs and extend the fishing time during the offshore fishing operations, our research group designed a set of independent photovoltaic power generation system which could be used as the auxiliary power supplement. On the basis of the structure features of fishing vessels and the features of solar energy resources in their fixed operating area in Hainan Province, we used qualitative and quantitative analysis to evaluate the effects of PV array arrangement strategy on power generation performance. Under the premise of basic electricity consumption in fishing vessels, such as communication and life use electricity, we proposed an optimization strategy of photovoltaic systems. Integrated photovoltaic power generation, energy storage and inverter, system control were used in our research to design and complete the configuration principle of the load, photovoltaic systems, storage batteries and other component parameters in photovoltaic systems, which helped to solve the technical problem of the stable operation of the solar photovoltaic systems in marine environment. In addition, PVsyst software was used to successfully simulate and analyze the feasibility and effectiveness of this system in the medium-sized wooden fishing vessels. Our research provides a new idea of the application of the photovoltaic power generation system in fishing vessels, as well as the maximum utilization of solar energy resources.
