This paper proposes a new photovoltaic generation system which effectively uses generated power of shadowed cells. In this system, a capacitor is connected to the solar cell module in parallel. The generated power of the shadowed cells is charged into the capacitor. This charged power is added to the solar cell array output power. The proposed system needs no external power supplies and is very compact and cost-effective. The energy efficiency of the system is much better than that of the bypass diode method. The experiment shows the usefulness of this system.
