Abstract: For known household electric appliances exclusively equipped to be powered with solar-generated electricity by a buffer accumulator, it is necessary to have either high levels of light intensity permanently, or a consumer with very low energy requirements. A device supplying solar-generated electricity to low power appliances, ranging between 1 W and 1000 W has not yet being concretely produced. The invention concerns a low power household appliance (31) comprising, for this purpose, a displacement module (33) connected to the solar generator (41) and the buffer accumulator (38) such that it is possible to obtain a waterfall type device supplying solar-generated electricity. Consequently, the optimisation is carried out for a very low input current (Iin), supplied by the solar generator (41) to the buffer accumulator (38) within the range of the buffer accumulator compensating current, current which is obtainable with the lowest levels of light intensity, of the order of 1mW/cm<2>, with respect to a very brief discharge interval (t2), of the order of one thousandth part of the charge interval (t1). Hence, the low power household appliance can be produced by using different displacement modules, in the form of different household appliances for which the interval of use is very brief compared to the rest interval.
