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:Many people in the market offer 10% cheaper than you, why should I choose your company? Can you do the same price?

A:As a matter of fact, the factories in Guangdong and Zhejiang area are really 10% or even more cheaper than us, but even with such a cheap price, their profit is still higher than ours, the main reasons are:
(1)Their procurement cost of solar cells is low. They always use reverse current and low-efficiency solar cells and never do Flash and EL testing at all. Although the appearance after production is not big difference with A grade solar panels, but the problem of cell cracks and mixed cells of different grades are serious. This is the main cause of the hot spot effect, which can lead to fires.
During the production process, GAMKO has 3 EL tests and 2 Flash tests, which from the string welding machine, intermediate inspection, and final inspection to avoid hidden cracks in the solar cells and the solar cells mixed different grades.

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.
