The Suntech STA040-12 is a 40 Watt, 12 Volt solar panel, composed of 36 multicrystalline silicon solar cells connected in series to produce the 12 Volt output. For each 18 cell series strings, one bypass diode is installed.

Provides power in a range of sunlight conditions to RV, marine or caravan batteries. Suitable for multiple 12 Volt appliances.

Cells are laminated between high transmissivity, low-iron, 3mm tempered glass and a sheet of tedlar-polyeaster-tedlar (TPT) material by two sheets of ethylene Vinyl acetate (EVA). A heavy-duty anodized aluminium frame provides strength and convenient mounting access.
