Just FYI, i received my July electric bill on Friday. Power generation charges are about $0.12/kWh, but various charges (distribution, other charges) bring the total per kWh to almost $0.24. As best I can calculate we used 1140 kWh, generated about 750 of that. It's a bit hard to calculate because my bill is generated on the 15th of the month and my solar reporting is on a calendar month, but June and July production here is pretty equal.I think that's a lot of electricity, but I'm in a 25 year-old house that has received some Mass Save energy saving measures but otherwise is pretty typical. 2,800 square feet, central air and a pool. And the second part of June was pretty hot, a bunch of 90 degree days.
Net metering from the Spring covered the bill and I still have enough credit to pay August, most likely. Without solar my bill would have been about $275.
