In a battery recharging arrangement for an automotive vehicle, one or more solar batteries, together with recharging current control means to charge an automotive vehicle battery, are disposed with supporting metal fixtures at a plurality of different positions to which solar energy is applied so as to prevent the rechargeable batteries mounted in an automotive vehicle body from becoming excessively discharged. The solar batteries are positioned on the roof of a vehicle or mainly within the passenger compartment at appropriate elevation angles, so that as long as the vehicle is in the condition wherever solar energy is applied, solar energy can be obtained at any position of the sun regardless of the direction the vehicle is moving in or of the place the vehicle is parked since at least one of the disposed solar batteries will be effectively exposed to sunlight. The solar batteries so disposed at a plurality of different positions within the passenger compartment are protected from dirt or splashes of mud to keep the batteries in good working conditions at all times. In addition, if appropriate light focusing devices, such as Fresnel lenses, are positioned over the solar batteries, the solar energy collecting performance will further be enhanced.
