Challenges
●Market Share Erosion: Structural shift toward POE and EPE films creates substantial competitive pressure. Advanced module technologies including bifacial dual-glass and N-type cells increasingly specify POE or EPE encapsulation for superior moisture resistance and thermal stability. EVA market share declining from historical dominance toward minority position by late forecast period as premium module segments adopt advanced materials. Manufacturers must accept market share loss or invest in POE/EPE capabilities requiring new formulation expertise and raw material supply chains.
●Intense Price Competition: EVA film market demonstrates severe price competition driven by overcapacity, industry concentration, and customer cost pressure. Encapsulation film costs represent only 4%-7% of module costs, creating continuous downward pricing pressure. Smaller manufacturers struggle to maintain viability against market leaders with superior scale advantages. Industry profitability challenges intensified during 2024, forcing operational efficiency improvements and capacity rationalization.
●Raw Material Cost Volatility: EVA film profitability demonstrates high sensitivity to EVA resin costs comprising approximately 90% of total expenses.
