The benefits of a detailed understanding of costs across the solar PV supply chain are often overlooked. From the production of polysilicon to the final assembly of solar modules, every step is exposed to distinct cost drivers that influence the overall economics of solar PV technology.

This IRENA report, the associated Solar Supply Chain Cost Tool and dashboard, offer a transparent, data-driven perspective on the economics of the solar PV supply chain across selected countries.

As manufacturing cost data are difficult to obtain, the model includes a set of modified assumptions that users can adjust. It provides a comprehensive view of each step of the process of solar PV module manufacturing, offering clarity on materials, processing and assembly costs at each stage.

By understanding where costs are concentrated, manufacturers, investors and policymakers can make more informed decisions, optimise production strategies, and identify opportunities for cost reductions and efficiency improvements.
