PROBLEM TO BE SOLVED: To provide a power supply system that suppresses a stop of power generation by a photovoltaic section even if the amount of power generation by the photovoltaic section suddenly drops.SOLUTION: A power supply system 1 that has a photovoltaic section 10, and a power storage device 50 having a storage battery 52 capable of being charged with/discharged of power and a charger 51 for charging the storage battery 52 with power from the photovoltaic section 10, and that charges the power storage battery 50 with power from the photovoltaic section 10 and supplies power released from the power storage device 50 to a particular load 60 includes: a solar radiation meter 80 for detecting a quantity of solar radiation received by the photovoltaic section 10; and control means 100 for calculating predicted power Pe predicted to be generated by the photovoltaic section 10 on the basis of the quantity of solar radiation detected by the solar radiation meter 80 (Step S102), and controlling the charger 51 such that the storage battery 52 is charged with only power less than the predicted power Pe (Step S103). |
