On track to cover 100% of electric - Christopher

Solar panels are live and kicked out 36kWh on a winter day yesterday. I am guessing production will be even higher in the summer. On track to cover 100% of electric. Looking forward to nearly nonexistent electric bills and a green-conscious in the near future! Thanks Advanced Solar and MD SUN!
