This report is available at no cost from the National Renewable Energy Laboratory (NREL) at www. A solar inverter, or PV inverter, converts the direct current (DC) output of a photovoltaic solar panel into a utility frequency alternating current (AC) that can be fed into a commercial electrical grid or used by a local, off-line electrical network. The project involves the simulation and analysis of a 50KW grid tied photovoltaic inverter system using MATLAB/ simulink. It discusses how solar energy works, the components of a solar energy system (collectors and storage), and current applications such as heating, cooling, transportation, and electricity generation.
