Narrow panels open up mounting spots that standard modules cannot reach, and at just 405 mm wide this 80W GWSOLAR panel is made for them: the strip of roof beside a vent, the coachroof of a boat, a narrow shed panel or a balcony rail. It produces 4.79A at 16.8V for 12V battery charging, with monocrystalline PERC cells running at approximately 19.0% conversion efficiency. A full parallel cell configuration means that shading, dirt or snow on part of the surface costs far less output than it would on a conventional panel. The all black finish looks unobtrusive once fitted, and the panel measures 1039 mm x 405 mm x 30 mm at approximately 4.8 kg. A 1 m cable with MC4 connectors is supplied for fast connection to a charge controller.
