Powercom group has successfully developed into a leader in the PV industry based on its strong vertically integrated business model, producing its own polysilicon, cells, modules, and PV inverters in-house. The control and efficiency achieved from this integrated value chain helps to continuously improve the production process as well as ensure high quality and cost-effective products to our customers.
The crystalline silicon-based PV manufacturing value chain starts with the processing of quartz sand to produce semiconductor-grade or solar-grade polysilicon feedstock.
After controlling our own polysilicon production, we have business strategic partners to subcontract to turn polysilicon into solar wafers for us.
Wafers are then manufactured into solar cells by TGE through a multi-step manufacturing process that includes etching, doping, coating and applying electrical contacts. Solar cells are then interconnected and packaged to form solar modules, which can be packaged together with PV inverters as solar complete sets, are then distributed to system integrators, service providers or directly to end-users, for installation for on-grid or off-grid solar systems.
