Unlike photovoltaic systems installed on land, photovoltaic systems applied to the offshore plant have the characteristicthat is installed in a limited space. For single point mooring plant, it is advantageous in terms of a reliable power supplyto be installed in different directions of photovoltaic panels, because it is not possible to identify the position of the sun byrotation of the plant itself. Differences of installation angle between photovoltaic panels make a difference of the intensity ofradiation irradiated on each photovoltaic panel, and it brings loss of generation quantity due to the partial shading. In order toprovide a photovoltaic system suitable for offshore plant, the modeling which contains multiple photovoltaic panels controlledby single controller is performed. Then, it was examined how the output characteristics of the photovoltaic system changeabout the difference of the intensity of radiation that varies depending on the altitude of the sun. Finally, through the simulation,a development model of the photovoltaic system which is suitable for offshore plant is suggested.
