Off commercial electric between March 4, 2011 and Aug 31, 2018.
The return to commercial power was partial.
Commercial is cheaper than backup propane generator and I
have both a Chevy Volt and Chevy Bolt to charge.
Prioritizing solar production over grid power,
only using grid power if the batteries get low and no sun.

I constructed this panel in 1980
from 36 Radio Shack(remember them) 1 amp cells.
The cost was around 10 dollars per cell. It worked for about a year. I kept a plexiglass
cover on them when I wasnt around. It operated one light
bulb and a Ten-Tec Argonaut 509.
