How
a Solar Energy System Works
Solar
photovoltaic (PV) or electric power systems convert sunlight
directly into electricity. When direct sunlight hits the
semiconductor material in a solar module, electrons are freed
and create an electric current.
A residential solar power system enables a residential homeowner
or commercial business owner to generate some or all of their
daily electrical energy demand. When a solar system is
installed, it is connected to the local utility so that excess
power (generated by the solar panels) can be fed into the
utility grid, and any power needed above and beyond what the
solar system can produce, is drawn from the utility grid.
Solar panels are typically mounted on the roof of a house or
commercial facility, or else ground mounted in a garden or piece
of land close to the site.
The
key components of a solar electric system are as follows:
Solar Modules: Solar modules convert sunlight to
electrical power. They are typically mounted in a steel frame
which in turn is attached to the roof of a home or commercial
property or ground mounted on a piece of land close to the site.
