Thin-Film CdTe Solar Panel Recycling

What Happens to Old Thin-Film CdTe Solar Panels?

Last reviewed by Marcus Williams on 02 April 2026

Currently, many owners don't know how to dispose of their thin-film CdTe solar panels once they reach the end of their 25-year lifespan. Thin-Film CdTe Solar Panel Recycling Few recycling programs exist, but First Solar's dedicated facility offers a reliable option for proper disposal and material recovery.

Old Thin-Film CdTe Solar Panels are typically discarded improperly due to lack of awareness or available services. However, when recycled through First Solar's programme, these panels undergo thorough mechanical shredding followed by chemical treatment to extract valuable materials like cadmium telluride and copper. The process ensures 90% material recovery while adhering to hazardous waste regulations.

According to the UNEP, A single tonne of circuit boards contains 40-800 times more gold than a tonne of ore.

How Are Thin-Film CdTe Solar Panels Recycled?

First Solar operates the only dedicated CdTe recycling programme globally, ensuring proper disposal and high material recovery rates. They start by mechanically shredding panels into small pieces. Then use chemical treatments to separate valuable components such as cadmium telluride and copper. This process yields a 90% material recovery rate, making it highly efficient compared to other solar panel types.

What Materials Are Recovered?

Thin-Film CdTe Solar Panel Recycling recovers several key materials including cadmium telluride (75%), glass (90%), copper (80%), and semiconductor materials. These materials have significant value in the recycling market, with cadmium telluride being particularly valuable due to its rarity.

Where to Recycle Thin-Film CdTe Solar Panels

First Solar operates two main recycling facilities: one in Perrysburg, Ohio, and another in Frankfurt-Oder, Germany. Additionally, specialized hazardous materials (hazmat) facilities handle the safe disposal of cadmium waste. These locations ensure proper handling and processing of thin-film solar panels.

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

Regulations and Producer Responsibility

Thin-Film CdTe Solar Panels are classified as hazardous waste in the EU due to their high cadmium content. In California, similar regulations apply, requiring producers like First Solar to pre-fund recycling at point of sale. This ensures that end-of-life disposal is environmentally responsible and cost-effective for consumers.

The Solar Waste Problem by 2030

Since 2005, First Solar has recycled over 25 million pounds of CdTe modules through its dedicated programme. As more panels reach the end of their lifespan, recycling capacity must increase to handle the growing volume of waste from utility-scale solar farms decommissioning thousands of panels simultaneously.

Utility-scale solar farms often include detailed plans for decommissioning in their initial project proposals or bond documents. These plans cover logistics such as bulk panel removal and transport to dedicated recycling facilities. At scale, the cost per panel can range from $5 to $20 for bulk shipments versus $30 to $45 for individual residential panels.

Decommissioning Planning

Decommissioning large-scale solar installations requires detailed planning involving logistical challenges like transporting thousands of panels safely and efficiently to recycling centers. Costs vary based on the number of panels, distance from facilities, and handling hazardous materials like cadmium. Utility farms typically budget between $5 and $20 per panel for bulk shipments compared to higher residential rates.

Logistics and Cost

When decommissioning large-scale solar installations, logistical planning becomes critical. At Thin-Film CdTe Solar Panel Recycling, transporting thousands of panels necessitates coordination with recycling centers equipped to handle hazardous waste safely. First Solar's facilities in Ohio and Germany are well-equipped for such operations. For utility farms, the cost per panel ranges from $5 to $20 when handled in bulk shipments. Residential removals can be more expensive at $30 to $45 per panel due to smaller quantities and increased handling requirements.

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

By following these guidelines and using First Solar's recycling programme, solar panel owners can responsibly dispose of their thin-film CdTe panels while recovering valuable materials for reuse.
