Plotting microFIT Revenue and System Costs to March 2013

I keep logging the daily power generation and the bank keeps logging my 2nd mortgage payments for the system. Time for another update for you to see if this thing really does make any money. Below are the results for revenue, microFIT payments (cheques from Guelph Hydro), and the loan payments. You'll notice that the microFIT payments are just keeping pace with the loan payments! Hummm,  think I need to figure out why my metering of revenue is so different than my power utility's metering. I have spoken with several friends with PV solar systems in Guelph and in other utility regions and they all report similar findings - no one's meter show LESS power produced than what their utility is reporting, and paying, them.
