The designing of a positioning system for PV modules used to supply a stand alone consumer

The paper is related to aspects concerning the realization of a positioning system for PV modules. One describes the design of the main parts of the system. The PV modules are used to supply a stand alone consumer. The system´s efficiency is improved if it is properly orientated with respect to the highest intensity of the light. The proposed positioning system is an automated two axes system which orientates the PV modules from East to West and from North to South respectively. The drive system used to orientate the PV modules contains two H-bridges and two DC motors. Finally, the testing of the entire positioning system based on a dedicated software is presented.
