From Waste to Resource: Driving EU’s PV Solar Energy into the Future

The solar PV capacity has grown rapidly worldwide, surpassing 1 TW by 2022 and 260 GW in the EU by the end of 2023.


With a lifespan of 25-30 years, a significant portion of PV panels will reach end-of-life in the next decade, leading to a tenfold increase in decommissioned modules by 2050.


Managing end-of-life PV waste is critical, especially in the EU where it’s classified as e-waste under the WEEE directive, putting the responsibility on manufacturers for collection and recycling.

Unlocking Global Resource Potential

Achieving 28% of global power supply from PV by 2050 necessitates:


Installation of 14,000 GW of PV capacity, resulting in:


At the same time, significant volumes of secondary raw materials can be released, including:

Project structure

Work packages for improved circularity

19 project partners from 9 countries will collect, treat, and upgrade solar panels that have reached their end of life, densify their value, and release them to serve as new products for solar energy and other purposes. The project comprises 14 interdisciplinary work packages (WP):

How we will do it

QUASAR will develop and implement solutions for systematic collection and management of end-of-life PV-modules, integrating various technologies and methodologies:

By doing this, QUASAR will foster:

QUASAR’s recycling technologies target End-of-Life recycling rates of 70-90% for silicon, metals, glass and polymers with high purity for reuse in new PV module manufacturing and other industries, with revenues of more than 13 € per module.
