House Data -
Electrical Energy
Usage
We can start to see trends in these
charts. The array started producing in November of 2006. Our data was
reliably collected from about that time. The first complete year of data
collection was 2007. We are generating on average 1/5 to 1/3 of the electrical energy we
consume.
The first billing period affected
by generated power was January 03, 2007.
Note: the local utility decided to
bill for 4 months in 2012 for some reason. So May through September (121
days) are bundled together rather than the usual two month billing. Only
the first chart is affected by the change. It looks as if we went crazy
with power usage.
