Solar PV Waste to Yield 100% of Future Material Demand by 2050

Resources Conservation and Recycling · 2023

Key Findings

01Cumulative PV waste in Australia is projected to reach 2,000,000–3,000,000 tonnes by 2050 under conservative installation forecasts.
02Under ambitious installation scenarios, PV waste could be 1-2 times higher than conservative estimates.
03Recovered silver and aluminium from EoL PV systems could supply 30% of future PV demand within 5 years, 50% within 15 years, and up to 100% within 25 years.

Application

Design takeaway

Design solar products with their end-of-life recovery and reuse in mind, ensuring materials can be efficiently extracted and reintegrated into the supply chain.

How to apply

When designing new solar technologies or systems, consider the materials used and how they can be easily separated and recycled. Develop product architectures that support disassembly.

Project actions

01Investigate the material composition of products you are designing.
02Consider how your design choices will impact the product's recyclability or reusability.

Method & Evidence

Strengths & Limitations

Strengths

+Utilizes up-to-date installation data.
+Considers distributed lifetime estimates by system size.
+Includes market share and material composition over time.

Limitations

Accurately predicting future technology adoption, material degradation, and the development of recycling processes can be challenging.

Reliability & validity

The study's reliability is enhanced by using current data and considering multiple forecast scenarios. Validity is supported by the comprehensive inclusion of factors influencing waste and recovery.

Think critically

How might the development of new, more efficient solar panel technologies impact the projected waste volumes and material recovery rates?

Design Principles

"Design for Circularity: Maximize material recovery and reuse at the end of a product's life to create a closed-loop system."

This insight underscores the critical need for robust end-of-life management strategies for solar technologies. Designing for disassembly and establishing efficient recycling infrastructure can transform waste into a valuable resource, reducing reliance on virgin materials and mitigating environmental impact.

What This Means for Your Design

Old solar panels can be a goldmine for new ones! By 2050, the materials from broken solar panels in Australia could be enough to make all the new solar panels needed.

How to use in your project

1.Use the projected waste volumes to justify the need for sustainable design solutions in your design project.
2.Quantify the potential resource recovery from your proposed design's materials.
