摘要： There is disclosed a photovoltaic power control system equipped with at least one inverter for inverting an output of a solar cell array to AC power, and having charge-and discharge control means for charging a surplus portion with respect to the power for expected use of the output of the solar cell array to a storage battery and discharging shortage portion with respect to the power for expected use of the output of the solar cell array from the storage battery by detecting the surplus or shortage produced between the output of the solar cell array and AC power for expected use inverted by the inverter, the improvement comprising weather fluctuation pattern selection means for selecting one weather pattern out of various kinds of weather patterns preset based on weather information at a time point when the weather is forecasted on the day when the power is generated by the solar cell array; and workable pattern selection means for selecting one actuation pattern of the inverter corresponding to the weather pattern selected by the weather fluctuation pattern selection means out of various actuation patterns of the inverter preset corresponding to the weather pattern.
