Solar PV installations are forecast to reach about 1.7 TW in 2025 and about 1.9 TW in 2026, driven by continued demand growth. Global capacity topped 2,343 GW by end-2023, but the supply chain still hinges on concentrated manufacturing capacity. Logistics slowdowns and lead-time shocks then translate into measurable delivery pressure across modules, wafers, and cells.
Key Takeaways

Interpretation
Cost Analysis Interpretation
Solar supply chains are being squeezed by logistics and inventory costs, where logistics can reach about 10% of global GDP and freight and logistics run 3% to 15% of product costs, so delays of weeks from port congestion and inventory carrying costs of 20% to 30% of inventory value per year can materially erode economics, while improving trade facilitation by up to 15% and cutting lead times by 2 to 6 weeks can provide meaningful relief.
