Commercial Utility-Scale Solar Panel Recycling

What Happens to Old Commercial Utility-Scale Solar Panels?

Last reviewed by Marcus Williams on 02 April 2026

Old Commercial Utility-Scale Solar Panels are typically removed and either recycled or sent to landfill if no recycling infrastructure is available. Recycling facilities recover valuable materials, reducing waste and environmental impact.

Commercial Utility-Scale Solar Panel Recycling isn't as widespread as it should be due to the high costs involved and a lack of regulatory mandates in many regions. Despite this, there's growing interest and investment in recycling facilities because utility-scale arrays are massive-often comprising thousands of panels. When these panels reach their end of life after 25 years. They need proper disposal or recycling to avoid harming the environment.

According to the UN Global E-Waste Monitor 2024, The world generated 62 million tonnes of e-waste in 2022, up 82% from 2010.

How Are Commercial Utility-Scale Solar Panels Recycled?

Commercial Utility-Scale Solar Panel Recycling involves bulk decommissioning: panel removal, on-site sorting, and transport to certified recyclers. Steel racking is typically sent to scrap yards, while panels are processed via thermal or mechanical methods to recover materials like silicon, silver, copper, aluminum, glass, and steel.

The process starts with the bulk decommissioning of solar arrays. Panels are removed from their mounts and sorted on-site for initial quality checks. Next, these panels travel by truck or rail to recycling facilities like We Recycle Solar in the US or Veolia in France. At these certified recyclers, panels undergo thermal or mechanical processing to separate materials efficiently. Steel racking is usually diverted straight to scrap yards due to its high value.

According to the European Parliament, less than 1% of rare earth elements in e-waste are currently recycled.

What Materials Are Recovered?

Commercial Utility-Scale Solar Panel Recycling recovers silicon (85%), silver (90%), copper (75-85%), aluminum (65-75%), glass (95%), and steel racking. Recovery rates vary, but the overall process yields significant amounts of reusable materials.

For instance, silicon makes up about 20% by weight of a typical solar panel, and recycling can recover around 85% of it. Silver is another valuable material-about 1 gram per panel-and recovery rates are typically between 90-95%. Copper wires account for approximately 10% of the panel's weight, with recovery rates around 75-85%, while aluminum frames and connectors have a lower but still substantial rate of about 65-75%. Glass, which comprises up to 75% of a solar panel's mass, has an almost perfect recycling rate at 95%.

According to the WHO, e-waste contains over 1,000 different substances, many of them toxic.

Where to Recycle Commercial Utility-Scale Solar Panels

We Recycle Solar (US), PV CYCLE (Europe), Veolia (France), and ROSI Solar are key facilities for recycling Commercial Utility-Scale Solar Panels. These companies have the capacity to handle large volumes of panels and recover valuable materials efficiently.

For instance, We Recycle Solar in California has a processing plant designed specifically for utility-scale solar panel recycling. In Europe, PV CYCLE processes over 100 million solar modules annually across multiple facilities. Veolia operates several plants in France dedicated to solar panel recycling, each capable of handling thousands of panels per year. ROSI Solar offers services tailored to large commercial and industrial projects in Germany.

Regulations and Producer Responsibility

Commercial Utility-Scale Solar Panel Recycling is regulated by the EU WEEE Directive, US EPA (no federal mandate yet), SEIA National PV Recycling Programme (voluntary), and Washington EPR law. These regulations aim to reduce waste and promote sustainable practices.

The EU WEEE Directive requires producers to take back and recycle end-of-life electrical equipment, including solar panels, from consumers free of charge. In the US, there's no federal mandate for solar panel recycling yet, but some states like Washington have enacted Extended Producer Responsibility (EPR) laws that hold manufacturers accountable for their products' waste management at the end of life.

The Solar Waste Problem by 2030

By 2050, Commercial Utility-Scale Solar Panel Recycling is projected to face a cumulative waste problem of 78 million tonnes globally. This projection indicates that utility-scale solar arrays will account for about 60% of installed capacity needing decommissioning.

According to the International Renewable Energy Agency (IRENA), global solar panel waste could reach up to 15 million tonnes by 2030 alone, with utility-scale installations contributing significantly due to their scale. This highlights the urgent need for strong recycling infrastructure and regulatory frameworks to manage this growing challenge effectively.
