PURPOSE: A foldable door system is provided to be stably opened or closed with improved reliability and reduced cost. CONSTITUTION: A foldable door system(1000) comprises a door frame unit(100) and a door guide unit(200). The door frame unit is placed between first and second walls, and one end of the door frame is fixed to the first wall, and unfolded toward the second wall. The second wall is placed with a predetermined distance from the first wall. The door guide unit is coupled to the other end of the door frame unit, and the door frame unit is folded toward the first wall or unfolded toward the second wall. The door guide unit comprises a solar module unit(210), a conversion storage unit(220), a monitoring unit(230), a driving unit(240), and a drive control unit(250), and a movable unit(260). The solar module unit outputs solar energy. The conversion storage unit converts the solar energy into first and second power. The monitoring unit monitors the gap between the first and second walls by the first or second power. The driving unit outputs first and second driving power in order that the door guide unit reciprocates between the first and second wall. The drive control unit controls the monitoring unit and the driving unit. The movable unit forces the door guide unit to reciprocate by the first driving power.
