These panels were manufactured out on the west coast and appear to be samples provided to someone. The company has since gone bankrupt along with Solyndra of the same era. These panels do appear to be complete as they have their junction boxes and MC4 connectors in place. With the 22V rating under load these are great as “12v” panels if you want to run a simple PWM charge controller but also work just great with an MPPT charge controller. They were made to be glued down on a metal roof for permanent installation but I don’t see why you couldn’t use them as portable panels, even if they are a bit longer than a typical flexible solar panel.
