10 watt solar panel capable of charging 12 volt large cell batteries (12amp and above). A heavy duty anodized frame provides strength and convenient mounting access. Cells are laminated between high transmissivity, low-iron, 3mm tempered glass and sheet tedlar-polyester-tedlar 'TPT' material by two sheets of ethylene Vinyl acetate 'EVA'. This protects against moisture penetrating into the module. The low profile junction box on the underside allows a flush mounting on a flat surface.
