Summary: | The invention discloses a solar energy utilization system, and a cool box, air conditioner or pump included therein. The solar energy utilization system (100) is provided with a solar panel (101), a motor (122) that is driven by solar output power, and a motor stall prevention device that prevents a motor stall during driving, and as the motor stall prevention device, any of the following is selected: (a) a motor stall prevention device that limits the solar output voltage to a voltage higher than a voltage at which the solar panel outputs maximum power at that point; (b) a motor stall prevention device that limits the solar output voltage to a voltage at which, when the output voltage is changed on a P-V curve, the rate of change becomes negative; and (c) a motor stall prevention device that is configured from a capacitor (317) which is connected in parallel to the solar panel and stores power generated by the solar panel. |
