Evaluating multi-axes sun-tracking system at different modes of operation in Jordan

A concise overview on recent research work on sun-tracking system is presented. Also, an experimental investigation on the effect of using multi-axes sun-tracking systems on the electrical generation of a flat photovoltaic system (FPVS) was carried out to evaluate its performance under Jordanian climate. Multi-axes (N–S, E–W, vertical) electromechanical sun-tracking system was designed and constructed. The measured variables were compared with that at fixed axis. It was found that there was an overall increase of about 30–45% in the output power for the North–South axes (N–S)-tracking system compared to the fixed PV system. Also, it was found that the N–S axes sun tracking is the optimum.
