What is a solar electric or
photovoltaic system?
Photovoltaic (PV) systems convert
sunlight directly to electricity. They
work any time the sun is shining,
but more electricity is produced
when the sunlight is more intense
and strikes the PV modules directly
(as when rays of sunlight are perpendicular
to the PV modules). Unlike
solar thermal systems for heating
water, PV does not use the sun's
heat to make electricity. Instead,
electrons freed by the interaction
of sunlight with semiconductor
materials in PV cells are captured
in an electric current.
PV allows you to produce electricity—
without noise or air pollution—from
a clean, renewable resource. A PV
system never runs out of fuel, and it
won't increase U.S. oil imports. Many
PV system components are manufactured
right here in the United States.
These characteristics could make PV
technology the U.S. energy source
of choice for the 21st century.
The basic building block of PV technology
is the solar “cell.” Multiple
PV cells are connected to form a PV
“module,” the smallest PV component
sold commercially. Modules
range in power output from about
10 watts to 300 watts. A PV system
connected or “tied” to the utility
grid has these components:
• One or more PV modules, which
are connected to an inverter
• The inverter, which converts the
system's direct-current (DC) electricity
to alternating current (AC)
• Batteries (optional) to provide
energy storage or backup power
in case of a power interruption
or outage on the grid.
AC electricity is compatible with
the utility grid. It powers our lights,
appliances, computers, and televisions.
