1.Many people in the market offer 10% cheaper than you, why should I choose your company? Can you do the same price?
As a matter of fact, the factories in some areas of China 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.
(2)Some factories are poorly equipped and staffed mostly by old people, which will reduce the cost of production, but the
consequence is that even if the best materials are used, there's no stable equipment, only relying on manual welding, handling and gluing, which will cause hidden cracks, chipping edges, missing corners, and insufficient glue of the solar panels. All these will affect the efficiency and use life of solar panels. A large number of second-hand panels in the market come from those unqualified factories.
2. It's my first time purchase in China, I'm worried about the security of my payment. I'm worried about not being able to deliver on time. I'm worried that the goods I receive are much less than what I expect, and there is no return channel.
Our regular payment is 30% in advance and 70% before shipment, we accept third party inspection before shipment. We also accept LC at sight. For some countries, we accept 30% prepayment and 70% payment against copy of bill of lading.
In addition, we also opened the STS payment method. Customers pay to a third party company and we can only receive the payment after we submit the bill of lading and other shipping documents after shipment.
3. Can I arrange personnel to stay in the factory or inspect the goods before shipment, and then pay the final payment after passing the inspection?
