Abstract
The City of Austin Electric Utility is using stand-alone
photovoltaic (PV) systems comprised of solar photovoltaic modules and
lead-acid batteries to provide DC electricity to fifteen water flow
meters used by the City of Austin Water and Waste Water Department. It
was less expensive to provide electricity using stand-alone PV systems
than through traditional electric distribution line connections. A
30-year economic analysis indicates that the photovoltaics will save the
Electric Utility $61000. The savings are realized after accounting for
battery replacements every five years and maintenance costs. Due to the
success of the fifteen stand-alone photovoltaic installations, the
Electric Utility is implementing a program to identify other cost
effective applications of photovoltaic in the electric utility
distribution system
