Abstract: The supply unit comprises a box type profile frame (1), whose base rests on wheels (2) and on whose top side (3), a square frame (16), as seen from above, is placed, said frame containing a solar panel (7). This can be swiveled about a horizontal axis (8) and is so connected to one of the top sides of the box type profile frame (1). A peripheral, square frame (5) of same size, each containing a solar panel (6), is connected in a swiveling way to each side of this square frame (16), so that out of the five square frames (16;5), a cube is formed when these frames are swiveled down. The peripherally connected square frames (5) can be swiveled to the plane of the central square frame (16) and can be locked in this position to the central square frame (16).
