Five Years of Residential Photovoltaic System Experience at Tucson Electric Power
Abstract
Tucson Electric Power Company (TEP) is a U.S. utility leader in the
early adoption of photovoltaic power generation with over 6.0 MWdc
of grid-connected photovoltaic (PV) systems installed in its service ter-
ritory since 2000. A signifi cant element of the TEP photovoltaic effort is
the SunShare PV hardware buy-down program that has been offered to
TEP customers since 2001. During the past five years, 282 residential-
size systems totaling 655 kWdc of crystalline silicon collectors have been
installed in the Tucson area through SunShare. Much has been learned
regarding performance, cost, maintenance, installation, and design of
these systems. This article presents an assessment of these topics and
a perspective associated with a family of systems within this PV pro-
gram.
