Performance comparison of a two PV module experimental setup using a modified MPPT algorithm under real outdoor conditions
Research output: Contribution to journal › Article
In this work, a flexible, low-cost testing system for PV applications is presented, and two identical PV modules have been compared at the same environmental conditions. A model-based (MB) MPPT algorithm, previously developed by the authors of this study, has been used. The MB algorithm has been evaluated and its efficiency is reported as 99.65%. The experimental test has been carried out and the performance of the developed architecture is validated, and two PV modules have been compared in real-time. It has been shown that the generated energy percentage difference between two identical PV modules is 0.6%. It is also worth mentioning that the proposed testing system is capable of hosting, evaluating and comparing four different MPPT algorithms, four PV modules and a combination of them.
