STP040-12 40 Watt 12 Volt Solar Module

The GSSTP040-12 is a 40 Watt, 12 Volt solar panel, great for travellers and industrial uses alike. The STP040-12 will provide power in a range of sunlight conditions to RV, marine or caravan batteries. This model is ideal for multiple 12 Volt appliances.

The GSSTP040-12 modules are composed of 36 multicrystalline silicon solar cells of similar performance, interconnected in series to obtain the 12 Volt output.

A heavy-duty anodized aluminium frame provides strength and convenient mounting access. For each 18 cells series strings, one bypass diode is installed. 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.
