Top-Con Cell Technology - 425Watt Bifacial Solar Panel

Bifacial solar panels are the latest technology that is able to convert sun rays of the sun into clean energy from the front and rear sides. This means higher energy efficiency and up to 20% more production from the same panel frame.

Bifacial panels have been proven by scientific studies to produce higher energy yield. They also have a longer life span than ever recorded from solar panels. The manufacturer offers a 30-year warranty on performance and 12 years on mechanical parts.

Solar Panel Features

  • Bifacial technology enables extra power to be harvested from the rear side of the panel
  • Total energy production is increased by 20 % 
  • Glass-to-glass lamination (instead of class back sheet) has exceptional durability and better heat distribution. It also allows better cooling. 
  • The hot spot effect is reduced significantly due to the contribution of half-cut cells and glass material.  

Top-Con Half-Cut Solar Cells

Half Cut cells have a new geometry that helps to reduce internal wiring losses by 50% . The shorter connection paths between the cells help to reduce thermal dissipation and increase the efficiency of the PV module. The interconnection is achieved with thinner narrower bus bars, allowing more sunlight to be absorbed. 

Bifacial Coefficient. The back side of the panel performs better when the panels are installed on the ground 

  • Irradiance on the ground
  • Irradiance on the rear side
  • Reflected irradiance on the front
