The sun is always the same price and is there. Barring a nuclear winter -- but then it's game over anyway.
I am looking at the ROI not the monthly savings in cash lay outs. Dependability and reduction of environmental damage is of more interest really. Twice in the past 5 years the electric power has shut down for days. Late March a storm cut power for 14 hours. Pain in the ass no electric to power the furnace or my water well.
