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 module. 


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 module.

Lower Operating Temperature

As the half-cut cells only have the half working current, the power thermal loss of the PV module during operation can be reduced considerably by 25% and the operating temperature of the PV module also is lower, which improves the PV module reliability and increases the overall power output.


Lower Shading Loss

The twin section layout of the cell strings in a PV module enables the module to continue to produce at least 50% of the overall energy even when one part of the module 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.

Q1:We like to buy your panels, cause the price is good, but the price is not most important, I don't like to buy the trash, how do I know your solar panel have a good quality, everybody say they are A grade panels, how I can trust you?

A:Firstly, we make new panels not stock panel, we will providing the flash test report,Series number, Power rates , voltage, current all mentioned on the flash test report for individual solar panel, The stock panel have no any database. You don't know if they are defective or broken panels. But its not enough. Please ask Gamko provide the flash test photo and EL photo for each panel.


Q2:I am also worry about my payment safe, How can you guarantee me 100% payment security?

A:if you do worry about the payment safety so either I, lets do "Alibaba Trade Assurance Payment" for both safety.

Q3:How To Ask for Support if product failure in warranty?

A:1. Email us about the PI number, serial number, product S/N number, PCB board number most importantly, is the description of failure products on the condition that it is operated correctly, to the best, show us more detailed pictures or video.

2. We will submit your case to our after-sales department to satisfy your demand. However, we believe our quality, and I believe if any quality problem, you can get the refund from our company directly.

3. Usually, within 24 hours, we will email you the best solutions.
