A mobile PV (photovoltaic) system using thin film solar cell is proposed at the first part of this paper. The system is suitable for an emergent power supply at shelters because of the lightweight and portability. At the second part, the efficiency of a boost chopper for each PV module using SiC MOSFET was measured and compared with the converters with Si MOSFET. Finally, prototypes of the boost chopper for each PV module using Si/SiC MOSFET demonstrated the operation with a PV simulator, which shows the converter with SiC MOSFET has an advantage when the irradiation is set to be relatively low.
