Title: Power supply system provided with photovoltaic generator

Abstract: A power supply system includes a photovoltaic generator, a load to which electric power is supplied from the photovoltaic generator, an electrical system for receiving a portion of the electric power generated by the photovoltaic generator and supplying electric power to the load, and a control unit for controlling the reception and the supply of the electrical power by the electrical system. To ensure that the photovoltaic generator generates electric power at an optimal operational point, the control unit is adapted to not operate when the maximum electric power P.sub.max generated by the photovoltaic generator and an electric power P.sub.L consumed in the load are equal to each other, and to be operated when P.sub.max >P.sub.L, thereby permitting the electrical system to receive a surplus electric power .DELTA.P1, and to be operated when P.sub.max <P.sub.L, thereby supplying a deficient electric power .DELTA.P.sub.2 from the electrical system to the load.
