Abstract: In this paper, a step-by-step approach of planning, designing and optimization of an unceasing single-phase grid-connected photovoltaic power plant based on real world conditions is shown. The power plant design is for a system that works continuously for all 24 hours in order to deliver continuous supply to the grid. This is due to compensate the usage throughout the day. The location of the real world climate condition chosen from is School of Electrical and Electronic Engineering, UniversitiSains Malaysia, NibongTebal, Pulau Pinang. The content includes the interpretation and tabulation of the power demand and environmental factors to develop proper technical approach to power sizing for generation based on data derived from a weather station at research location, choice of control method for the control module which includes implementing the Multiple Power Point Tracking (MPPT) technique through the power converters and also a system with very little power losses as it is delivered to the grid. The design is then proven by simulation using MATLAB/Simulink software.
