Power from Thomas Keating's roof

is now generating a significant fraction of the electricity we use to cut metal

it is fun to watch the rise and fall of the power the solar cells generate as the sun rises and falls. Here is a late September's day.... we are hoping for more - perhaps over 60 KW -  come mid-summer.
