The
size of your PV system is up to you. For instance,
if you want to meet 50% of your electricity need
with your PV system, you would choose a system
sized to produce about half of your usual electricity
demand. As a starting point, consider what your
present electricity needs are, and examine past
electric bills. You can also contact your utility
company and request the total electricity demand,
measured in KWh over the last 12 months. Take
this annual electricity demand and compare it
to how much electricity the PV system would produce
on an annual basis. This will also give you an
idea of how much money you will save on your electricity
bill once your PV system is installed and generated.
The great thing about a PV solar system is you
can start off small and expand your system later
down the road; this is especially helpful for
those who are undecided how big they want their
system. Payback is faster
on smaller systems!
