Performance modeling and investigation of fixed, single and dual-axis tracking photovoltaic panel in Monastir city, Tunisia

摘要: Abstract Presented in this paper was an overview on research works solar radiation basics and photovoltaic generation. Also, a complete PV modeling investigation the effect of using multi-axes sun-tracking systems electrical generation carried out to evaluate its performance case study Monastir city, Tunisia. The effects azimuth tilt angles output power module were investigated. instantaneous increments generated by mounted single dual-axis tracking system relative traditional fixed panel estimated. results show that yearly optimal angle faced due south is close 0.9 times latitude. gain made single-axis analyzed. monthly are more noticeable for two critical periods which correspond those surrounding summer winter solstice dates. It reaches value 10.34% 15% periods, respectively. However, installed with 5.76%. In some applications, covering loads at early morning or late afternoon hours order optimize exploitation suggest adjustment orientation different from direction installation. recommendation evaluated. This 30% 44% respectively days.
