PowerFilm Thin Film Flexible Solar Panel 10W, 12VWrite a review

We use this panel on our sailboat to keep our house battery topped off. Works quite well, once you determine which cable is positive as there seems to be no indicator of such. A simple electric meter will determine which side is positive, then mark that with tape. Would be nice if the pane came with red/black indicators on the connectors. A tip - if using a flooded battery, check the water level monthly with a solar or trickle charger.
