Year 1 Actual Solar Production Thru January 2012

After 1 full year, our PV system generated 2,927 kWh of electricity which was 5% more than the original system annual estimate of 2,781 kWh. I've only been paying $2-3 in taxes each month (SCE informed me that they would be billing me in May for the balance of usage charges), so our final billing has not been updated. Here is an Excel file of our actual solar production and savings.

Total Production for Year 1 (1/26/2011-1/25/2012):
Production: 2,927 kWh
Percent of Annual Predicted Production (2,781 kWh): 105%
Actual vs. Predicted Production Better/(Worse): +146 kWh
CO2 Saved: 4,829 lbs
Estimated Savings: $539.41

Monthly Production:
January 2012 (1/1-25): 105.98 kWh
December 2011: 90.01 kWh (we lost about 20 kWh of production from Pasadena windstorm power outages)
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)
