  • SOLAR ENERGY UTILIZATION SYSTEM, AND COOL BOX, AIR CONDITIONER OR PUMP INCLUDED THEREIN
    Publication number: 20150349692
    Abstract: A solar energy utilization system includes a solar panel, a motor that is driven by solar output power, and a motor stall prevention device that prevents the motor during drive from stalling, and as the motor stall prevention device, any of following devices is selected: (a) a motor stall prevention device that limits solar output voltage to voltage higher than voltage at which the solar panel outputs maximum power at the point in time; (b) a motor stall prevention device that limits solar output voltage to voltage at which, when the output voltage is changed on a P-V curve, a change rate becomes negative; and (c) a motor stall prevention device that is configured by a capacitor which is connected in parallel to the solar panel and stores power generated by the solar panel.
