Solar PV demand and capacity additions are becoming more concentrated, even as global deployment scales fast enough to stress logistics and cross-border trade. With solar generating about 5% of global electricity in 2023, the ripple effects show up for developers, installers, and the workforce in major markets like the United States. This page connects rising logistics costs, longer lead times, and forecast uncertainty to practical responses such as visibility tools, cloud planning, transportation management, and traceability.

Cost Analysis Interpretation
For cost analysis in the solar supply chain, logistics pressures are significant because logistics costs have climbed to about 10% of global GDP in 2022 and can account for 3% to 15% of product costs, with further upward risk from congestion-driven weeks of port delays and inventory carrying charges of 20% to 30% of inventory value per year.
