Residential 2.5 kW Grid-Tied Solar System
Topeka Indiana, September 2006
This 2.5 kW solar system consists of solar panels mounted outside on a
tracker, electrical components in the basement of their home,
meters outside the home, and a battery backup that will provide
emergency power if the utility power goes down. The dual axis
AZ-225
Wattsun tracker, on which the twelve Sharp 208
panels are mounted, automatically tracks
the sun year round North to South and daily East to West. The
solar panels take rays from the sun and produce direct current,
which is converted by an OutBack PS1 battery grid-tie inverter into 120VAC alternating
current, providing the house with power. An OutBack PSPV Combiner Box was used for
circuit breakers and disconnects at the pole.
These homeowners want to do their part in helping out the
worldwide energy crisis. He says, “We all need to
help combat global warming and air pollution, as well as
become less dependent on foreign oil. Our solar energy
system does not add to resource depletion, a problem we
feel is getting fast out of control.” Besides producing their own electricity, they have replaced their
old furnace with a new high efficiency gas furnace and high
efficiency air conditioner, as well as using fluorescent bulbs
throughout the house.
