Wet and sunny? You must have that ideal of rain mostly at night. I'd like that.

Last year was the first time we produced more power than we used, but just barely. Made 9610 kWh, used 9603. That surprised me.

I've often thought that would be the ideal, too! But then I realized that would likely cause us to overheat.

I think it was more that we caught enough of the thunderstorms to keep it from getting overly dry this year. Some years those thunderstorms just pass us by every time, sometimes to the north and sometimes to the south.

I'm guessing you do not heat with electricity. We actually heated with wood pellets for about three days over the weekend since it was so cold. Back to electricity now...

In terms of our 12-month running net consumption, we had managed to be barely ahead at the end of November by 80 kWh. But it's been pretty cold since then. Plus January 2016 set production records here, so not much chance of a repeat. As of today, we're net consumers of about 400 kWh over the past 12 months. We still have 1.4 MWh stored up, but I don't expect that to last through February.
