(DE19817057-A1)   NOVELTY - The arrangement includes a unit (5) for determining the output of the energy balance of the solar generator (2), relative to the engine generator (1). A second unit (10) is controlled by the determination unit (5), for reducing the generator output corresponding to the solar current supply, so long as the output or power used in the vehicle electric circuit, is greater than that delivered from the solar generator. A third unit (11) also controlled by the determination unit is provided for separating the generator from the engine (13), if the output or power used in the electric circuit of the vehicle, is equal to or smaller than the power delivered from the solar generator.    USE - Motor vehicles.    ADVANTAGE - Contribution of current supply by the solar generator is optimally used and fuel consumption due to loading of the engine driven generator is minimized.
