An Analysis of the Harmonics and Power Factor Effects at a Utility Intertied Photovoltaic System

This paper outlines the harmonics and power-factor characteristics and effects of a single residential photovoltaic (PV) installation using a line-commutated inverter. The data were taken during a five-day measurement program conducted at the John F. Long House, which is a prototype residential PV installation located in Phoenix, Arizona. The magnitude and phase of various currents and voltages from the fundamental to the 13th harmonic were recorded both with and´ without the operation of the PV system. A candidate method of modeling the installation for computer studies of larger concentrations is given.
