How Does
It Work?
PV cells are normally fabricated
using special semiconductor
materials that allow electrons,
which are energized when the
material is exposed to sunlight,
to be freed from their atoms.
Once freed, they can move
through the material and carry an
electric current. The current flows
in one direction (like a battery),
and thus the electricity generated
is termed direct current (DC).
Grid-Connected PV System
A “grid-connected” system generates
its own electricity and feeds
its excess power into the utility
grid for later use. This does away
with buying and maintaining a
battery bank. You can still use
battery banks to provide backup
power when the grid goes down,
but they are not required.
Smaller systems have a box –
a small grid synchronous inverter
– mounted on the back of each
panel. Larger systems have one
large inverter, which can handle
many panels (as in a stand-alone
system). Both types convert DC power output into AC power. Then
they synchronize this output with
the grid to slow down the electrical
meter. They can even turn the
meter backward. If the PV output
is less than the load consumption,
the meter slows down.
