This presentation describes an effective design of a photovoltaic (PV) system with an MPPT (maximum power point tracking) algorithm and phase-change material. The application of an MPPT algorithm and phase-change materials are two different techniques, but in this presentation these two techniques are used together in the same PV system. Modelling of the PV module, implementation of the MPPT algorithm and selection of the phase materials have been described with best clarity. Finally, a significant enhancement of PV power has been obtained using a SOLKAR 36-W PV module.
