FAQ
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
