Longi Solar Panels Half Cut Technology

On April 29, 2019 LONGi announced that the front side power of its 72-cell Bifacial half cut module exceeded 450W, achieving the world’s highest power in this module type. This new record was tested and verified by renowned certification agency TÜV-SÜD.

“LONGi monocrystalline half-cell module combines monocrystalline PERC cell technology and bifacial half-cell module construction to effectively reduce package loss and increase average output by 5-10W. Half-cell has obvious advantages in power generation under weak light and shadow conditions and excellent heat spot resistance. This new record in module power is another step in our innovative breakthrough and journey.” 

Dr. Lv Jun, Vice President of LONGi Solar 

“Half-cut” solar technology refers to the solar cell being separated into two parts, cut by a mature infrared laser. The effect of this is to halve the required working current, increasing the power of the module while reducing its thermal (heat) loss.
Cutting solar cells in half results in half the current and double the voltage. Solar modules with double the voltage would not be advantageous, as the higher string voltage would result in half the amount of modules that can be connected per string to the inverter. As such, most manufacturers adopt a string layout to produce voltages similar to standard solar modules.

The benefits of Half-Cut solar cell technology include:

  • Higher Efficiency: when a solar cell is cut in half, the amount of electrical current that is carried by each busbar is also reduced by half. This decrease in resistance within the busbars causes an overall increase in its efficiency. For the LONGi system, this equates to a power increase in the module of 2%. This is significant.
  • Lower Hot Spot Temperature: hot spots in the module can cause irreversible damage to the cells. Reduction of hot spot temperatures of between 10-20°C improves the reliability of the module.
  • Lower Operating Temperature: reduces thermal loss and improves both module reliability and power gain.
  • Lower Shading Loss: half-cut modules can still achieve 50% power output during shading, including sunrise and sunset conditions.
LONGi offers a 12-year product warranty for materials and processing applied Hi-MO4 and Hi-MO4m range, a 25-year performance warranty for extra linear power output with the Hi-MO4m and 30-year performance warranty for the Hi-MO4 double glass series.
