Solar Production Thru November 30, 2011

Our solar PV system is now 10 months old and we are generating 13% more energy than the original system estimate. I have updated my savings calculator model with the actual solar production to date. I still haven't gotten a real electric bill. I've only been paying the taxes each month ($2-3). I thought they were going to charge me once a quarter, but I guess it will be all at year end.

Total Production To Date:
Production: 2,740 kWh
Percent of Annual Predicted Production (2,781 kWh): 98.5%
Actual vs. Predicted Production Better/(Worse): +306 kWh
CO2 Saved: 4,521 lbs
Estimated Savings: $487.00

Monthly Production:
November 2011: 142.94 kWh
October 2011: 200.17 kWh (we had our house tented, so I estimate we lost about 20 kWh of production)
September 2011: 255.36 kWh
August 2011: 331.44 kWh
July 2011: 352.72 kWh
