I have four Solbian SP100 type semi-rigid solar panels available. These are the same as the two on the roof of my bus (Devon pop-top) . Condition of the cells similar to these two. View attachment 66364 These are high efficiency 20 volt 5 amp type panels, claimed by the manufacturer to be up to 23% efficient, with a plastic cladding and a plastic backing. They can be curved by up to 25% in one axis. They are about 500mm wide and 1000 mm long. Fixing via screw holes at edge or PU glue under the panel. These units are second hand and used, have been repaired after seawater corrosion of the terminals then used on a garage roof.
