Suntech 30Watt 12Volt Multi Crystalline Solar Module


The STP030-12 is a 30 watt, 12 volt solar panel, and will provide enough power to trickle charge a 12V vehicle or deep cycle battery. Helps run pumps, lights, fans, and small appliances such as stereos, televisions and VCR's in caravans, boats or cabins.


The STP030-12 modules are composed of 36 multi-crystalline 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-polyester-tedlar 'TPT' material by two sheets of ethylene Vinyl acetate 'EVA'. This protects against moisture penetrating into the module.
