PROBLEM TO BE SOLVED: To allow a user who introduces a photovoltaic power generation system to know an annual power generation amount and the most efficient arranging method for solar cell panels, before installing the solar cell panels.SOLUTION: The device for predicting the amount of generated electric power of the photovoltaic power generation system includes a fixed condition input section 4 which inputs the longitude, latitude, altitude, and house azimuth angle of a house, a storage section 5 where monthly maximum/minimum fine weather rates, monthly mean wind velocities, and monthly mean maximum/minimum air temperatures of several years are input, a selection condition section 6 which inputs the rated value, attachment angle, and roof azimuth plane of a solar cell panel, and the number of solar cell panels to be installed or the number of solar panels which can be installed, an arithmetic section 7 which obtains annual maximum and minimum power generation amounts by sequentially changing installation allocations of the solar cell panels to the room azimuth plane and obtaining monthly maximum and minimum power generation amounts through simulation with respective installation allocations, and a display section 8 which displays maximum values by the months among the monthly maximum and minimum power generation amounts and a maximum value in one year among the maximum and minimum power generation amounts. |
