This book presents a case study on a new approach for the optimum design of rooftop
grid-connected photovoltaic-system installation. The study includes two scenarios using
different brands of commercially available PV modules and inverters. It investigates and
compares several different rooftop grid-connected PV-system configurations taking into account
PV modules and inverter specifications. The book also discusses the detailed dynamic MATLAB
Simulink model of the proposed rooftop grid-connected PV system and uses this model to
estimate the energy production capabilities cost of energy (COE) simple payback time (SPBT)
and greenhouse gas (GHG) emissions for each configuration.The book then presents a
comprehensive small signal MATLAB Simulink model for the DC-DC converter operated under
continuous conduction mode (CCM). First the buck converter is modeled using state-space
average model and dynamic equations depicting the converter are derived. Then a detailed
MATLAB Simulink model utilizing SimElectronics® Toolbox is developed. Lastly the robustness of
the converter model is verified against input voltage variations and step load changes.
