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 swivelled 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 swivelling 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 swivelled down. The peripherally connected square frames (5) can be swivelled to the plane of the central square frame (16) and can be locked in this position to the central square frame (16). The box type profile frame (1) contains several box type modules (24-26), which can be inserted like drawers from one side and can be arrested in these inserted positions; these modules are for various functions like accumulation of energy from sun and wind, preparation of drinking water, pumping water, delivery of electric power or Direct Current-Hydrogen generation through fuel cells.
