The major bottlenecks for solar PV scale-up are projected to center on materials scarcity. Copper and tin are the most critical materials and will constitute the main bottleneck of solar PV development in most scenarios. However, unlocks are available, as supply could ramp up (especially for tin).
Global capacity for manufacturing wafers and cells, which are key solar PV elements, and for assembling them into solar panels (also known as modules), exceeded demand by at least 100% at the end of 2021. By contrast, production of polysilicon, the key material for solar PV, is currently a bottleneck in an otherwise oversupplied supply chain.
The Solar Photovoltaics Supply Chain Review, produced by the DOE Solar Energy Technologies Office with support from the National Renewable Energy Laboratory, will help the federal government to build more secure and diverse U.S. energy supply chains.
Meanwhile, the solar industry in Europe is warning of a looming installer bottleneck (SolarPower Europe, 2020), and in India, labour shortages (exacerbated by Covid-19 restrictions) slowed solar PV deployment across the country in 2020 (JMK and IEEFA, 2021).
The purpose of this paper is to propose a conceptual framework for handling end of life (henceforth EoL) scenarios of solar photovoltaic (solar PV) panels, which includes different options available to
