Photovoltaic generation sail electrical system and ship provided with same

The invention relates to a photovoltaic generation sail electrical system. The electrical system comprises a photovoltaic array, energy maximization modules, an energy storage module and an integrated controller, wherein the photovoltaic array is arranged on a sail, and the photovoltaic array comprises multiple photovoltaic assemblies which are connected in series or in parallel; each energy maximization module is provided with an anode input end, a cathode input end, an anode output end and a cathode output end, each energy maximization module is connected in parallel with the back of each photovoltaic assembly through the anode input end and the cathode input end so as to enable the photovoltaic assembly to work at a maximum power point, and each energy maximization module is correspondingly connected with the connecting position of the parallel photovoltaic assembly in the photovoltaic array through the anode output end and the cathode output end so as to form an electrical energy output line which is corresponding to the photovoltaic array and is used for outputting electrical energy; the energy storage module is electrically connected to the electrical energy output line and used for storing electrical energy; and the integrated controller is electrically connected to the electrical energy output line and the energy storage module and used for storing the electric energy into the energy storage module, and is also electrically connected to each energy maximization module so as to control the equal current output by the energy maximization modules positioned in a same serial line. The invention also relates to a ship provided with the electrical system. The electrical system provided by the invention has the advantages of large energy output and high energy utilization efficiency.
