Our 6/15/2012 electricity bill was $15.86 even though we made approximately 200 KWh more than we used. That’s because we don’t have net metering here yet. (Yet, as in… I assume some day there will be.)
And it looks like we’ve paid approximately $630 for electricity in the last year. If you pretend we have net metering, then that would have been roughly $630 / (11,000 – 8,400) KWh (used vs generated) = 24 cents/KWh. A bit expensive, but not outrageous for Massachusetts.
What this $630/yr makes me wonder is what it would cost to add a smaller PV array with batteries that is off-grid to power us at night so we’d have even closer to $0 electricity bills.
Eh, money probably much better spent on something practical for the family. Like a pool. Or our kids’ school tuition.
