Monthly Solar Production – September 2012

Pinterest

Another month, another $27 electric bill.  This is too easy.  :)

I’m still close to producing 75% of my total energy from my solar panels and am hoping I can finish that way for the year. Considering that I was expecting between 60-70% of my energy production from solar, I’m very pleased to be close to 75% through 10 months.

Here’s the updated numbers:

Period Ending Production As % of Usage Savings
Dec 21, 2011 223 kWh 32.5% $45.05*
Jan 24, 2012 288 kWh 34.5% $59.26*
Feb 23, 2012 419 kWh 72.2% $86.81*
Mar 23, 2012 484 kWh 87.7% $106.48*
Apr 24, 2012 663 kWh 110.4% $145.86*
May 21, 2012 536 kWh 107.4% $81.62
Jun 22, 2012 707 kWh 113.5% $107.72
Jul 23, 2012 767 kWh 75.1% $116.86
Aug 22, 2012 660 kWh 67.9% $98.93
Sep 21, 2012 616 kWh 77.6% $92.34
Overall 5,363 kWh 74.9% $941.03

*NStar 100% Green Energy rate

If there seems to be some inconsistency, it is due to monthly usage fluctuations, the number of days per billing period and NStar price changes.

Plus, it looks like I’m on target for $1,100 in savings on the year, although that number is inflated since I was on the NStar 100% Green Energy rate for half the year and was paying more for my electricity. I expect to save closer to $1,000 in coming years.
