Jinko Solar: new record efficiency and new module for rooftop systems with high snow or wind load
As we have observed, the solar industry is growing steadily. Some well-known manufacturers are launching new high-performance modules on the market and outperforming their respective efficiencies from month to month. The demand for solar products is not decreasing either. Rather the opposite.
This month, the Chinese photovoltaic manufacturer is attracting attention with a new record efficiency and a new module variant. In this article, we will take a closer look at Jinko’s innovations.
New record efficiency of 25.25 per cent for monocrystalline n-type solar cells is a fundamental milestone on the road to mass production
As recently as January 2021, the Chinese photovoltaic manufacturer’s efficiency was 24.9 per cent. Jinko calls the new record of 25.25 per cent an important breakthrough on the road to mass production of n-type Topcon cells. However, the date of the start of production of this n-type cell was left open. Material improvements in the cell process as well as the production on a CZ mono-Si substrate in the practical size of 267.4 square centimetres are said to have increased the efficiency here. Several advanced technologies have also been employed to achieve the high efficiency using ultra-thin polysilicon. These technologies include:
- Jinko Solar n-type wafer
- high conductivity passivating contact technologies
- surface passivation
- advanced diffusion system
In addition to high efficiency, Jinko Solars new Tiger Pro module series features special resilience to snow or wind load
Not only has the efficiency improved at Jinko Solar, but the Chinese solar module manufacturer has also placed a new module on the market for roof systems with high snow or wind loads.

This new module, named Tiger Pro 54HC, is based on 108 half-cells made of 182-millimetre wafers. It also achieves an efficiency of 21.3 per cent. It is specially designed for private roof systems, especially in areas with high snow or wind loads. Among other things, it is available in a total of five versions with outputs ranging from 395 to 415 watts.
