7 Trends & Outlook 2026
Asian Overproduction
Global module oversupply (650 GW vs 600 GW demanded) pressuring prices downward, especially Chinese PERC and TOPCon modules.
Rising EU Industry
European production capacities (France, Germany, Spain) increasing thanks to Net-Zero Industry Act and EIF support.
LFP Batteries: Continuous Decline
LFP costs falling (projections 500-600 €/kWh 2027) due to competition (BYD, CATL, EV Cells). Residential storage profitability improving.
Massive Rollout Expected
BNEF forecasts 649 GW solar deployment in 2026, driven by SDGs and competitive buyback tariffs.
