Let's start by asking how much does electricity
cost? At pge.com on the ResElecCurrent spreadsheet the average E1
cost is 18¢ per kilowatt hour (kWh). See example (1).
The cost of solar electricity is 16¢ per
kWh. See example (2).
In this example utility company electricity costs
11% more than solar power.
So, what's the kilowatt-hour cost for utility
company electricity? If your electric provider is PG&E and
your cost is $180 per month your usage is 1,011 kWh. Therefore
the cost of utility electricity is 18¢ per kWh.
Then, what's the kilowatt-hour cost for solar
power? That is the cost of the installed equipment divided by
the kilowatt-hours generated over twenty five years. A typical
three kilowatt solar system in Fairfield will cost about
$18,000 after incentives and will produce 112,000
kilowatt-hours in 25 years (18 / 112 = .16 ) . Therefore
the cost of solar power will be 16¢ per kilowatt-hour.
That is a simplistic but fair way to compare the
costs and you can clearly see that even for moderate utility
bills, the cost of solar power is less than utility electricity.
Ok solar power costs less than utility
electricity, now that home values have dropped and equity
financing for solar is rare, how can we get a solar system for our
The good news is that Talbott Solar now offers a
variety of equipment finance and lease programs for the highest
quality "Sunpower" solar electric systems.
