The expansion is to bolster the solar industry’s supply of the encapsulant, a critical component for module manufacturing, amidst concerns of EVA supply becoming a bottleneck as solar wafer, cell and module manufacturing capacity expands.
The thermoplastic polymer encapsulant is currently a bottleneck in solar PV module production, according to anecdotal evidence on the ground, and the new facility will therefore go someway in helping to alleviate a reported shortage.
Module manufacturers LONGi, JinkoSolar and Suntech have production centres in Chuzhou and, “as a supporting enterprise of photovoltaic modules”, Changzhou Better Film intends to “give full play to its own advantages in technology”, according to a company media release.
