Data From First Full-tracked Day

For the first month we're going to track everything on a daily basis, from 7:00 p.m. to 7:00 p.m. I'll set up a spreadsheet and maybe figure out how to display it here.

The first such period just ended and here's what happened. (Please note that this 24 hour period that just ended was IDEAL -- 100% sunny, long day, not hot enough for A.C.).

The inverters tell us we produced a total of 55.5 KWHours of energy.

The meter read 15,577 KWH on Saturday evening and 15,554 KWH just now. So during that period we supplied enough for our own needs and dumped 23 KWH out onto the power grid for others to buy.

The solar power inverters and the electric meter are both dealing in KWhours, but I'm not bothering to do any math that mixes data from the two sources. I can't imagine a KWHour from one is similar enough to a KWHour from the other to make any such calculations worthwhile.
