- The paper deals with numerical model of the system with photovoltaic generator feeding the DC commutator motor with permanent magnet excitement, by DC buck chopper. The motor drives its load of fan characteristic - centrifugal water pump. The system is of Stand-Alone type, and without the electric buffer source (electrochemical accumulator or supercapacitor). The simple circuit for Maximum Power Point tracking, with positive feedback from average value of motor’s armature voltage, has been applied in this system. The real system's diagram is presented and shortly described. The numerical model of the whole real system has been created in TCAD simulation software. This model's diagram is presented and described in details. The model of PV generator enables simple modeling of generator's cells insolation changes, and also different temperatures of the cells, independently. The results of computer simulations of such transient states as: start-ups of the motor for different PV cells insolation and temperature values, and linear increases and decreases of insolation, are presented. The good points and shortcomings of the described system and its model are recapitulated in the conclusions.
