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?

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.
