To provide a module wiring design method of a solar energy power generation system, with which the arrangement of modules and wiring pattern of a solar energy power generation panel are optimally designed.
Arrangement of the string and the state of the module are inputted and the module is classified at each string. Effective modules are extracted in sunny and shade conditions which affect array output power among the classified modules. The number of the obtained effective modules is calculated for each string, the strings are ranked, based on the number of the calculated modules in the sunny side, and the strings are rearranged. Current values of the modules in the shade conditions are reduced by dispersion rate and they are arranged. A maximum output operation point is calculated from the shape. The arrangement pattern of the strings is changed and the maximum output value is calculated repeatedly, and the wiring pattern of the module is obtained with maximum output power.
