The cost of a solar PV system varies based on: the size of the installed
system; is it on the roof or ground mounted; are any upgrades to the
existing electrical system needed or not; local jurisdiction requirements
and a variety of other variables all affect the price. But every system is
custom designed to meet your needs and is tailored to your desires so set a budget and then investigate what that will buy you in energy
independence. As a rule of thumb if an average home consumes 10,000
kWh per year of electricity to build a solar Photovoltaic system that
would produce all that is needed would cost approximately $20,000
before tax credits. A simple way to get a ballpark idea is multiply your
yearly consumption (kWh) by $2.00 to get an idea of what buying a
Photovoltaic system will cost.
