Longi Solar panels
Standardised width, choice of three different lengths, full utilisation of limited roof area, realising the maximum installed capacity
Gallium-doped technology overcomes the LID degradation and guarantees the long-term power generation stability of the module
The power of half-cell module increases, and the hot spot temperature reduces because of lower working current
Operating current lower than 11A; applications in all DG projects; matches with various inverters and optimisers; avoids high wiring loss
9BB design further improves current collection capability
Flexible installation, including pitched roof, flat and angular roof and flat roof with herringbone detail
1st year degradation <2%, linear degradation <0.55%/year

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
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.
