Recycling & End-of-Life of Solar Panels

1. The Issue: From Waste to Resource

78 Mt

Cumulative PV waste by 2050 (IRENA projection)

The worldwide installed solar base accumulated since 2010 will reach end-of-life en masse between 2040-2050

25-35 years

Actual lifespan of a solar panel

Average degradation of 0.3-0.5% per year. Panels retain 80-85% capacity after 25 years

94-96%

Recyclability by mass

Solar panels are NOT hazardous waste. Components are easily valorizable

0.70 €

Eco-fee per panel (2024)

Recycling financing integrated into purchase price. Free for the panel owner

🔄 Circular Economy Challenge

Solar panels are complex products containing high-quality glass, aluminum, crystalline silicon and rare metals. Rather than landfills, an efficient recycling stream transforms this "waste" into raw material for new panels or other industrial applications, creating a sustainable value loop.

2. Solar Panel Composition (25 kg average)

75% Tempered glass (~10 kg) — Main structure, light transmission

10% Aluminum frame — Mechanical support, sealing

5% Silicon cells — Photovoltaic conversion (core technology)

5% EVA (ethylene-vinyl acetate) — Encapsulant, adhesive

3.5% Backsheet (Tedlar/plastic) — Rear insulation

1% Copper and connectors — Electrical circulation

<0.5% Silver and tin — Contacts, high-tech solders

Global Recycling Rate

94-96%

of total mass can be recovered and valorized

Structural components (glass, aluminum) are readily accessible at beginning/end of chain. Crystalline silicon (most delicate) allows reprocessing toward re-wafer or industrial reuse.

3. The SOREN Scheme in France

🏛️ Institutional Status

Former name: PV Cycle France
Renamed: SOREN in 2021
Status: Approved eco-organization
Approval: WEEE Directive (Waste Electrical and Electronic Equipment)
Financing: Eco-fee integrated into panel price

📊 Key Figures (2023-2024)

2023 Collection: 5,500 tonnes (+40% vs 2022)
Network: 500+ collection points in France
Eco-fee: ~0.70 € per panel (2024)
Recovery rate: > 94%
Cost to owner: 100% FREE

✅ How it Works

SOREN organizes collection, sorting and recycling of solar panels in France under state approval (extended producer responsibility). Manufacturers and importers finance the system via an eco-fee paid to SOREN. The owner of old panels has nothing to pay: SOREN finances collection and processing free of charge.

To recycle your panels: Contact SOREN (soren.eu) or drop them off with an approved installer or collection point in your region.

4. Detailed Recycling Process

Step 1: Collection and Transport

Panels collected from households, installers or industrial sites. Secure transport to approved treatment centers.

Step 2: Sorting and Dismantling

Separation of aluminum frames, junction boxes, cables. Visual inspection for hazards.

Step 3: Shredding of Laminates

Laminates (glass + cells + EVA) mechanically shredded into fragments of a few millimeters.

Step 4: Thermal Processing

Heating > 500°C to remove EVA (encapsulant) and plastic backsheet. Capture of valorizable gases.

Step 5: Mechanical Separation

Glass-silicon separation by density difference (flotation/decantation). Glass recovery > 98% purity.

Step 6: Metal Refining

Copper, silver, tin extraction via hydrochemical or hydrometallurgical processes. Recovery 95%+ of precious metals.

Step 7: Second Life and Valorization

Glass → thermal insulation, fiber optics, glassware. Aluminum → remelting (automotive, construction). Silicon → R&D re-wafer or silicon purification.

⏱️ Overall Timeline

From collection to final valorization: 4-8 weeks on average (depends on volume and panel type).

5. Regulatory Framework: WEEE and Extended Responsibility

🇪🇺 EU Directive WEEE 2012/19/EU

Classification: PV panels classified as WEEE since 2012
EU 2025 Target: 85% collection, 80% recycling
Responsibility: Manufacturer/importer finances collection and treatment
Waste Status: Not hazardous material (RoHS compliant)

🇫🇷 France: Regulatory Advance

Decree 2014-928: Strict WEEE transposition
SOREN approved: Since 2014 (formerly PV Cycle)
Performance: Collection rate ~5% (continent lagging)
Trend: Collection rate projection 50%+ by 2030

📋 New Developments: Ecodesign and Digital Product Passport

EU Ecodesign Regulation (under discussion): Proposes mandatory "digital product passport" for each solar panel. Will contain: precise chemical composition, material flows, recyclability, historical traceability. Objective: facilitate recycling and circularity long-term.

6. Second Life and Reuse: Emerging Market

♻️ Downrated Yet Functional Panels

Some panels, aged but still operating at 80-90% capacity, don't justify immediate recycling. These modules can be reconditioned for less demanding applications (humanitarian projects, agriculture, off-grid electrification) before actual end-of-life.

Humanitarian Projects

NGOs, village electrification, clinics

Agriculture

Irrigation, greenhouses, farm electrification

Emerging Markets

Developing countries, off-grid rooftops

🔧 French Panel Reconditioning Platforms

Sircome: Leading panel reconditioning provider France
Voltec Solar: Second-life specialist
Model: Functional test → cleaning → resale
Warranty: Often 5-10 years on reconditioned modules

⚖️ Legal Framework

Current status: Unclear, no harmonized WEEE standard
Classification: Varies by country (waste vs product)
Standardization: EN 50698 under discussion (reuse testing)
Trend: Clarification expected 2025-2026

💡 Circular Economy Opportunity

Second-life panels significantly extend their lifecycle value and reduce pressure on recycling. EU objective: 50% of panels recovered via reuse before 2040, not just recycling.
