For every solar energy system, a wafer is one of its most important components. This is because a wafer, also called a slice or substrate, is a thin slice of semiconductor, such as crystalline silicon, that is used for the fabrication of integrated circuits and, in the case of photovoltaics, to manufacture solar cells. With that description, we can see the absolute necessity of wafers in solar energy systems — and by extension, in solar installation businesses. Without wafers, solar systems and solar installation businesses won’t exist.
Because of the importance of wafers for solar energy systems, it’s understandable that you as solar installers would have a strong need for them for your business. Luckily, manufacturers and wholesalers of wafers exist, so they can definitely help you out. China is famously known for having a lot of these manufacturers and wholesalers. That is why if your solar installation business is located in China, you can surely find a reliable company within your own country.
In order to help you with your search, here is a list of ten manufacturers and wholesalers of wafers in China that you can look up.
