The downswing in the cost of PV cells is facilitating further development in China's solar panels industry. Most products adopt mono- and polycrystalline cells, which are more readily available that amorphous versions.

Shenzhen Xinonghua Solar-Energy Co. Ltd uses crystalline cells for a flexible solar panel that does not contain glass, making it practically unbreakable. The product is laminated with aluminum oxide, EVA and Tedlar.

Mainland China makers usually purchase solar cells from US, Germany, Japan or Taiwan.

Companies often have long-term contracts with their providers to ensure steady supply.
