The first night and day went okay. I was (and am) mainly concerned with my electric usage. It's a bit chilly here so I ran the furnace during the night. My battery capacity was down to 91% this morning. The day was overcast and raining, and I stayed away for most of the day. The solar panel managed to charge the batteries up to 97% at one point. Tomorrow is supposed to be sunnier, so it will be interesting to see the difference.
