	The possibility of constructing autonomic PV low power generators used for electric driving systems feeding emerged within last few years. These systems, usually 1 -phase AC driving systems, may be used in certain household advices. 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 of 3-phase AC 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. Chosen results of laboratory tests are presented in figures.
