Suntech 70Watt 12Volt Mono Crystalline Solar Module

Suntech 70Watt 12Volt Mono Crystalline Solar Module


Suntech’s STPSb features total efficiency of 12.7% Which delivers the maximum power output at peak hours. Ideal for off-grid and remote power systems. With a 25 year warranty, the module has high efficiency and long-lasting operating time even in a variety of rigorous conditions. Unique textured cell surface and bypass diode design is critical for the module to fully utilize and absorb sunlight and offer maximum usable power per square foot of solar array.




  • 36 high-efficiency Suntech Power Silicon Solar Cells
  • More power in peak hours through Suntech Power Cells
  • Optimized module performance with Nominal Voltage 12 V DC
  • Bypass diodes to avoid hot-spot effect
  • Cells are embedded in a sheet of TPT and EVA
  • Unique esthetic appearance of cells
  • Attractive, stable,heavy duty anodized aluminum frames with convenient mounting-access, for high wind-pressure and snow-load
  • The backside frames are equipped with drainage holes. So we eliminate the risk that rain or snow water may accumulate in the frame lumen and freeze or even bend the frame in cold season
  • Pre-cabled with fast-connecting systems
  • Customer-desired packing



  • 25 years Limited Power Warranty
