Power Bill

This is our power bill for December 2010 showing that we finally bought some net grid power from Allegheny Power (264KWh) Ever since the PV net meter system went online back in June, our bills have been virtually zip. Its hard to tell what we used per month last winter and spring because of the over-estimates the power company used. They are now required to read the meter every month and the net metering data is hand calculated.
This kind of bill is only possible with a 3600 watt array if you also have your usage under control. Its not hard to do, just upgrade lights, appliances and behavior. It took two years to trim our use so PV made sense.
