	The possibility of autonomic PV low power generators constructing used for electric driving systems feeding has emerged within last few years. The amount of energy produced by these unconventional energy sources depends on current weather conditions. The paper describes a new method of maximum power point tracking for photovoltaic generator feeding magnetoelectric DC-motor in stand-alone photovoltaic drive system without a buffer energy source. The specific quality of this method is assuring the maximum power working point of the generator in an indirect way - by maximization of motor input power. This method makes maximum power point tracking independent of generator cells temperature and insolation, and of any changes of generator output characteristic (voltage-current) curves caused by light cells aging and shading of some cells, when shaded with snow or dirt. The chosen results of laboratory are been presented in fig.
