Jinko Solar is a solar manufacturer that was founded in 2006 originally producing silicon wafers and is widely recognised as a global leader in the solar panel industry. The company has an annual production capacity of 17.5GW of monocrystalline silicon wafers, 10.6GW for solar cells, and 16GW for modules, as of March 31, 2020. As of June 2020, Jinko has informed Solar Choice that they have 9 production facilities around the globe with an increased integrated annual capacity of 20GW for mono wafers, 11GW for solar cells and 25GW for Solar Panels.
The new release Tiger Series features many of the latest innovations in PV cell technology including larger format cells, multi-busbar (MBB) with 9 thin wire busbars (as opposed to traditional flat ribbon busbars).
- – Tiling Ribbon Technology
- – Half Cells Technology
- – 9BB PV Module Technology
- – New larger format – 66 cell panels
1. Tiling Ribbon (TR) Technology
Tiling ribbon is a manufacturing technique where the cells are slightly overlapped, much like shingled cells, to eliminate the gap between the cells and increase overall cell coverage which in-turn increases efficiency. To achieve this, Jinko uses a unique pressing process to join the thin wire busbars together. This has the added benefit of reducing costs, and almost eliminating the need for soldering which can contain traces of lead.
2. Half Cell Technology
By using half cells, The electrical current (i) flowing in each busbar will be halved. Therefore, the amount of internal losses will be ¼ of a full sized cell module. Under the same shadow condition, the power loss of the half-cell component is less than that of the full-cell component.
3. 9BB instead of 5BB
The busbar space reduction will help the 9BB PV module to reduce the intensity of the electricity between each cell, in order to increase the efficiency of the PV module. Moreover, the surface area of the busbar is 22% lower on 9BB than 5BB cells, which will increase the cells receiving surface, and the output of the PV module. This technology also helps in avoiding debris, cracks and broken gate risk effectively by utilising circular ribbons.
4. New larger format 66 cell panels
Another significant evolution with the new Tiger series is the increased number of cells per panel. For roughly the last decade, most manufacturers have built panels using either 60 cells for residential size panels. However, due to the overlapping (Tiling Ribbon) design, JinkoSolar have managed to squeeze in another row of cells resulting in a slightly larger size panel and increased panel voltage. This is a substantial shift away from the industry standard sizing and it will be interesting to see if other manufacturers follow.
