Thanks Richard, I have looked at these before but a 10amp controller seems a bit large for my 600ma panel. A 1amp controller would seem more appropriate.
This one may work just fine, but I can't find any data on power loss or efficiency of the controller. If it draws 200ma, that is a 30% loss for my small solar panel.
