Abstract:
This paper analyses the required values for development of rooftop solar panel systems with positioning mechanism systems. The use of sun tracking systems directly influences energy efficiency during the exploitation of solar power. An analysis has been performed of the angles typical for mechanism positioning. Parameters and requirements for the rotation of the sun tracking system are given for Kragujevac, Serbia, along two rotational axis. It is suggested that the rotation around the east-west axis be preformed day by day, and the rotation around the north-south axis by the hour. Finally conclusions have been drawn and suggested steps for the development of such mechanisms have been given.

Key words:
