The CP-55 is an 55 watt, 12 volt solar panel to suit almost any power requirement. A heavy-duty anodized aluminium frame provides strength and convenient mounting access. Cells are laminated between high transmissivity, low-iron, 3mm tempered glass and sheet of tedlar-polyeaster-tedlar (TPT) material by two sheets of ethylene Vinyl acetate (EVA). This protects against moisture penetrating into the module.
