True Black Technology
Based on nanotechnology, very fine holes are formed on the surface of the circular ribbon to reduce the diffuse reflection of part of the light and ensure as much light as possible is eventually absorbed into the solar cell. It makes the silver ribbon invisible, so the whole panel become true black and more beautiful.
Kada True Black panel absorb and use light more efficiently, and effectively reduce glare as well.
BIG HUGᵀᴹ Technology
The BIG HUGᵀᴹ technology allows Kada SolarSkin to have up to 360-degree curvature, which can completely cover most objects, and provide unlimited freedom for specific scene design, enabling it to efficiently use sunlight to power various systems from any angle during 7*24 hours.
Half-Cut Cell + Twin Panel Technology
Half-cut cell + twin panel technology consists in cutting the solar cell in half by non-destructive cutting infrared laser and splits the conventional layout of 3 cell-strings in 1 electric circuit into the innovative layout of 6 cell-strings + 2 electric circuits in a PV panel.
This technology halves the electric current of the cell and reduces effectively the internal electric resistance on the cell ribbon and increases the panel power by 2%. The twin panel design minimizes the power loss in shading conditions, hence improves the system mismatch and heightens the efficiency of the PV system.
Lower Hot Spot Temperature
By halving the electric current of both the cells and the cell-strings, the hot spot temperature can be reduced by 50%, which enhances the reliability of the PV panel.
Lower Operating Temperature
As the half-cut cells only have the half working current, the power thermal loss of the PV panel during operation can be reduced considerably by 25% and the operating temperature of the PV panel also is lower, which improves the PV panel reliability and increases the overall power output.
Lower Shading Loss
The twin section layout of the cell strings in a PV panel enables the panel to continue to produce at least 50% of the overall energy even when one part of the panel or the cell string is shaded.
Multi-busbar Technology
In comparison with the conventional 5 busbar design, the innovative multi-busbar design on the cell can shorten the current collection transverse path by 50% and thereby reduce remarkably the cell internal resistance, which contributes a 1% - 1.5% increase in the power output compared with 5 busbar design.
The MBB design can also mitigate the performance loss caused by blocked electrical pathways in case of cell microcracks and finger electrode erosion due to external factors.
Bifacial Technology
The bifacial PV panels allow light to enter simultaneously from both the front and the back sides of a solar panel. By converting both direct and reflected light into electricity, bifacial PV systems can generate as much as 30% more energy than a comparable monofacial PV system.
The reflected light can come from a variety of sources, such as reflection from the ground or from a neighboring row of PV panels. The reflectiveness of the surface decides the albedo and hence the amount of the additional electricity generated of the bifacial PV panels.
