Off commercial electric since March 4, 2011.
Returned to partial commercial electric Aug 31 2018.
Cheaper than backup propane generator and I now
have a Chevy Volt and a Chevy Bolt to charge.
It will prioritize solar production over grid power,
only using grid power if the batteries get low.

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.
