IRENA Insights: Solar Supply Chain Cost Tool - understanding cost drivers in module manufacturing
The costs of manufacturing solar PV modules vary significantly across the supply chain, from polysilicon production to final module assembly. Understanding these cost drivers is essential to assess the competitiveness of solar technologies and identify opportunities for greater efficiency and cost reduction.
This webinar presents IRENA’s Solar Supply Chain Cost Tool, which provides a transparent, data-driven view of manufacturing costs across selected countries. It highlights key cost components, underlying assumptions and the breakdown of materials, processing and assembly expenses at each stage. The tool supports manufacturers, investors and policymakers in making informed decisions to optimise strategies and strengthen the economics of solar PV deployment.
