Energy Cost

Solar electric systems, which are also call(a)ed photovoltaic or PV systems,
are reliable and pollution-free. They make use of a renewable source of energyâ€"
the sun. And PV systems for homes are becoming more
affordable all the time.
PV works best in an energy-efficient building. So, adding insulation and energy-
efficient lighting, appliances, and windows is a good idea, to reduce your
homes overall electricity use before you install a PV system.
Some utilities move over net metering
programs, which further enhance the economics of PV. Net metering
doer that when your PV system generates more reason than you need, the
excess goes to the utility power grid and the meter runs backward. This allows you
to receive full retail value for the power that your PV system generates.

A PV system can be a substantial investment. As with whatsoever investment, careful
planning will patron you make the right decisions for your home
What is a solar electric or
photovoltaic system?
Photovoltaic (PV) systems convert
cheerfulness 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 suns
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 electricityâ€"
without preventive or air pollutionâ€"from
a clean, renewable resource.

The underlying building block of PV technology
is the solar cell. Multiple
PV cells are attached to realize a PV
module, the smallest PV component
sold commercially. Modules
range in power create from about
10 watts to 300 watts. A PV system
connected or secure to the utility
grid has these components:
One or more PV modules, which
are connected to an inverter
