Special Report on Solar PV Global Supply Chains The IEA examines the full spectrum of energy issues including oil, gas and coal supply and demand, renewable energy technologies, electricity markets, energy efficiency, access to energy, demand side management and much more. Through its work, the IEA advocates policies that will enhance the reliability, affordability and sustainability of energy in its 31 member countries, 10 association countries and beyond.

Solar PV’s demand for critical minerals will increase rapidly in a pathway to net zero emissions. The production of many key minerals used in PV is highly concentrated, with China playing a dominant role. Despite improvements in using materials more efficiently, the PV industry’s demand for minerals is set to expand significantly. In the IEA’s Roadmap to Net Zero Emissions by 2050, for instance, demand for silver for solar PV manufacturing in 2030 could exceed 30 of total global silver production in 2020 – up from about 10 today. This rapid growth, combined with long lead times for mining projects, increases the risk of supply and demand mismatches, which can lead to cost increases and supply shortages. The long-term financial sustainability of the solar PV manufacturing sector is critical for rapid and cost-effective clean energy transitions. The net profitability of the solar PV sector for all supply chain segments has been volatile, resulting in several bankruptcies despite policy support. Bankruptcy risk and low profitability could slow the pace of clean energy transitions if companies are unwilling to invest because of low returns or are unable to withstand sudden changes in market conditions. Trade restrictions are expanding, risking slower deployment of solar PV. As trade is critical to provide the diverse materials needed to make solar panels and deliver them to final markets, supply chains are vulnerable to trade policy risks. Since 2011, the number of antidumping, countervailing and import duties levied against parts of the solar PV supply chain has increased from just 1 import tax to 16 duties and import taxes, with 8 additional policies under consideration. Altogether, these measures cover 15 of global demand outside of China. IEA. All rights reserved.
