Renewable power sources are the best way to reduce the effect of green house gases and thereby global warming. Among them solar power may be seen as the most reliable due to its availability. But the solar PV system is expensive. So the main objective of this work is to develop a solar PV system which is cost effective without compromising on the efficiency of the system. The optimal operating point of each PV panel is different depending on the solar irradiation and temperature on the panel. In a string of panels the power of the entire string can be optimized and not on panel by panel basis. This paper focuses on power optimization tracking of individual PV panels using a single stage interleaved flyback converter. The proposed converter is having high voltage conversion ratio when compared to an ordinary buck boost converter. A detailed study conducted in this paper explains the practical and theoretical techniques for making the PV cells to work most efficiently all the time. A practical approach is made in this paper using the MATLAB atmosphere and to prove the quality of the theoretical concepts hardware results are also provided. The result proves that the efficiency of the entire system can be improved by optimizing each panel and the reduction of conversion stages helps to make the system more cost effective.
