> Applications that directly use DC from PV arrays is cheap Direct DC is very underrated in America. Almost everyone I know with solar panels is grid tied and they're missing out. Antique belt drive shop tools are cheap, relatively easy to restore and maintain, and lend themselves to solar conversion (just add DC motor). Only downside is that you can only work while the sun's shining.
