How They Work
Grid tie solar and wind systems simply tie into the electrical
grid through an AC distribution panel. These systems do not require batteries for
storing power but some systems do have batteries only for back-up power.
The main components of a system are solar panels or wind turbine, DC-AC
grid tie inverter, and DC/AC disconnect depending on what the local
electrical code requires.
In New Brunswick, N.B Power
and Saint John Energy have a system called net metering. If you are
producing your own power with solar or wind the power commission will
track what you produce and what you purchase from the utility by using
a net meter. If you ever produce more power than what is needed in your
home the extra power will go into the electrical grid and you will receive
a credit from the utility.
