Axitec AC-440TGB/108BB 440Watt 108 Half-Cell Bifacial Solar Panel

AXITEC, LLC AC-440TGB/108BB

The Axitec AC-440TGB/108BB eliminates the severe power drops and micro-cracking common in standard plastic-backsheet modules exposed to extreme heat. Gripping this ultra-rigid, dual-glass panel reveals a stiff, 25.0 kg rock-solid frame built to handle a heavy 5400 Pa snow load without twisting on the solar rails. Homeowners and commercial installers select this premium N-type TOPCon bifacial module over traditional panels to capture extra energy from ground reflections while maintaining a clean, low-profile all-black roof aesthetic.

• Product Performance
  

  The Axitec 440 distinguishes itself through its bifacial N-type TOPCon technology and superior low-light behavior, ensuring consistent energy production throughout the day by stopping micro-cracking and heat degradation.
