2018/03/11 Nine Years of Solar Panels
π 2018-03-11 01:01 in Solar
It's been 3 years since I did the last report. Sadly PG&E isn't doing reliable true up statements anymore, and with the alternate electric companies that are proving our electricity now, it's unclear what we'd have been paying anymore.

Anyway, here are the numbers:

Year #          PV Kwh  PG&E Kwh Used   House Kwh Used  Yearly Bill	EV (car)	
2010 - #1	8503	1602		10105		-$39.87	
2011 - #2	8813	1209		10022		-$38.80	
2012 - #3	8402	674		9076		-$110.43	
2013 - #4	8366	486		8852		-$134.06	
2014 - #5	8840	-30		8810		-$210.74	
2015 - #6	8665	1027		9692		-$41.38	
2016 - #7	8437	1386		9823		?
2017 - #8	8335	1910		10245		$26.21		613Kwh
2018 - #9	8665	1922		10250		?		209Kwh

Total 76689 10186 86875 N/A 822Kwh

A few notes:

  • EV use is very low because I don't drive much and mostly charge at work
  • The amount of energy I charged the car with at home amounts to about 2400 miles
  • In 9 years we took about 10Mwh from the grid, or what we'd have used in a year before
  • Our panels made 76Mwh, which at an average of 25c/Kwh would have cost $19,000, but due to time of use pricing, they actually saved us around $21,750, which is getting quite close to the panel costs. If the average price was closer to 30c/Kwh (very possible with tiers), then we saved about $26,000, which is the full price of the panels.
