A deployable structure comprises a mast and two storage rollers each supporting a flexible solar generator, the two storage rollers being articulated on the mast. The mast comprises at least one longitudinal rod and two lateral arms, inclined angularly in two opposite directions that are symmetrical relative to the longitudinal rod, each lateral arm comprising an end provided with a hollow guide. Each storage roller has a longitudinal axis comprising a bent end forming a pivot respectively articulated inside the hollow guide of a corresponding lateral arm, the pivot of each storage roller having an axis of revolution different from the longitudinal axis of the corresponding storage roller.
