A solar power generation system includes a solar panel that receives sunlight to generate power, a PV power conditioner that performs DC/AC conversion of the power generated by the solar panel, and a charging AC/DC converter that performs AC/DC conversion of power output from the PV power conditioner and charges a storage battery. Voltage of the power supplied to the PV power conditioner from the solar panel is acquired while the power supplied from a power system is stopped, and a change in power supplied to the PV power conditioner from the solar panel is obtained according to the voltage. Charge power that is output from the charging AC/DC converter to charge the storage battery is adjusted based on the change in voltage.
