Establishment of a reliable power supply is one of our new challenges to acheive "BESS-Polar experiment", a long-duration balloon flight in Antarctica. The power system is required to enable the detector system operation with a capacity of 600W during a flight period of 20 days, as well as to meet balloon experimental constraints including weight restriction of 300kg. solar battery is newly adapted as a power source, instead of primary battery utilized in the present BESS system. In order to verify performances of the system being developed, a technical balloon flight at Sanriku Balloon Centre was carried out. This report describes the overview of the solar battery system and the outline of the flight.
