Part 2 - Solar Panel Recycling: Technologies, Processes, Plants, Economics, Circular Models, and India’s New Waste Rules

Regulatory Landscape & India's New Waste Rules

India's regulatory framework for solar panel recycling underwent transformative change with the notification of E-Waste (Management) Rules, 2022, marking the first time solar photovoltaic modules are explicitly governed under national e-waste legislation.


E-Waste (Management) Rules, 2022: Overview

Notified by the Ministry of Environment, Forest and Climate Change (MoEFCC) on November 2, 2022, and effective from April 1, 2023, these rules represent a significant expansion and refinement of India's e-waste governance.


Key Changes from 2016 Rules:

  1. Expanded Scope: 

    • 2016 Rules: Covered 21 types of electrical/electronic equipment

    • 2022 Rules: Expanded to 100+ product categories, including:

      • Solar photovoltaic modules, panels, and cells (Chapter V dedicated provision)

      • Tablets, GPS devices, electronic storage devices, air purifiers

      • Medical devices, toys with electronic components

  2. Focus on Recycling Targets: 

    • 2016 Rules: Emphasized collection targets

    • 2022 Rules: Shifted to recycling targets (Schedules III and IV)

    • More stringent accountability for actual material recovery

  3. Centralized Registration: 

    • 2016 Rules: Multiple state-level authorizations

    • 2022 Rules: Single registration on CPCB portal

    • Streamlined compliance, improved data tracking

  4. Clear Penalties: 

    • Environmental compensation regime clearly defined

    • Prosecution provisions under Environment (Protection) Act, 1986

    • Penalties for aiding/abetting violations


Solar PV-Specific Provisions (Chapter V)

The 2022 Rules dedicate an entire chapter to solar photovoltaic waste, recognizing its unique characteristics and future volume.


Definitions:

  • E-Waste explicitly includes: "electrical and electronic equipment, including solar photo-voltaic modules or panels or cells, whole or in part discarded as waste, as well as rejects from manufacturing, refurbishment and repair processes"

Applicability: Rules apply to every:

  • Manufacturer of solar PV modules/panels/cells

  • Producer (importer or brand owner)

  • Recycler of solar PV waste

  • Refurbisher extending panel life

  • Dismantler breaking down panels


Obligations of Solar PV Manufacturers and Producers


1. Registration Requirement

Mandatory: All manufacturers and producers must register on the CPCB e-waste portal: https://cpcb.nic.in/e-waste/

Information Required:

  • Company details, production capacity

  • Panel types and quantities manufactured/imported

  • Material composition data

  • Collection and recycling plans

Penalty: Cannot operate without registration; dealing with unregistered entities prohibited


2. Storage Mandate (Transition Period)

Critical Provision: All solar PV waste generated up to year 2034-35 must be stored as per CPCB guidelines.

Rationale:

  • Recognizes current lack of adequate recycling infrastructure

  • Provides 12-year transition period (2023-2035) for industry development

  • Prevents premature landfilling while infrastructure scales up

Storage Guidelines (per CPCB):

  • Designated storage areas at manufacturing facilities or authorized locations

  • Weather-protected, secure storage

  • Inventory maintenance on CPCB portal

  • Annual reporting of stored quantities

Implication: Producers must plan for storage costs and space until 2035, creating economic pressure to develop recycling infrastructure.


3. Inventory Maintenance

Requirement: Maintain distinct, real-time inventory of solar PV modules/panels/cells on CPCB portal.

Data to Track:

  • Panels manufactured/imported each year

  • Panels sold to different states/customers

  • Estimated end-of-life timeline

  • Panels collected at end-of-life

  • Panels sent to registered recyclers

Purpose: Creates comprehensive data for waste forecasting and EPR target setting


4. Annual Returns Filing

Deadline: Online annual returns filed on CPCB portal

Contents:

  • Production/import data

  • Sales by state/customer category

  • Waste collection efforts

  • Recycling certificates obtained

  • Storage quantities (for waste generated before 2034-35)


5. Compliance with SOPs and Guidelines

Producers must follow Standard Operating Procedures (SOPs) and guidelines issued by CPCB regarding:

  • Collection mechanisms

  • Storage specifications

  • Transportation protocols

  • Safety standards


Extended Producer Responsibility (EPR) for Solar PV

EPR is the cornerstone policy making manufacturers responsible for end-of-life management.

What is EPR?


Definition: Extended Producer Responsibility means the obligation of producers of electrical/electronic equipment (listed in Schedule-I) to meet recycling targets (Schedules III and IV) through registered recyclers, ensuring environmentally sound management.

EPR Targets and Timeline


Important Clarification: Currently, solar PV waste is EXEMPT from EPR recycling targets until 2034-35. This exemption reflects:

  • Low current waste volumes

  • Infrastructure development period

  • Storage mandate instead


Post-2035: Expected that CPCB will set recycling targets for solar PV similar to other e-waste categories.

Likely Future Targets (Based on General E-Waste):

  • Year 1-2: Collect and recycle 30% of waste generated

  • Year 3-4: 50%

  • Year 5-7: 70%

  • Year 8+: 85%


EPR Certificate Trading Mechanism


How It Works:

  1. Producer's Obligation: 

    • Producer has EPR target (e.g., recycle 100 tonnes of solar waste in 2035)

  2. Recycler's Action: 

    • Registered recycler processes panels

    • Generates EPR certificate for quantity recycled

    • Each certificate digitally recorded on CPCB portal

  3. Trading: 

    • Recycler sells certificate to producer on online platform

    • Producer purchases certificate to meet obligation

    • Price determined by market (typically ₹15,000-25,000 per tonne)

  4. Compliance Verification: 

    • Producer uploads certificates to demonstrate compliance

    • Shortfall triggers environmental compensation

Benefits:

  • Creates revenue stream for recyclers beyond material sales

  • Incentivizes formal recycling sector

  • Provides flexibility for producers (buy certificates vs. operate own collection)

  • Market-driven pricing improves efficiency


Refurbishing Certificates (Deferred Liability)

  • Innovation in 2022 Rules:

    1. Refurbisher extends life of panels (e.g., by 5 years)

    2. Generates refurbishing certificate for extended life quantity

    3. Producer purchases certificate, deferring EPR obligation

    4. When refurbished panel eventually reaches end-of-life, 75% of deferred quantity added to producer's EPR target for that year

  • Example:

    • Producer has 100 tonne EPR target in 2035

    • Purchases refurbishing certificate for 40 tonnes (5-year extension)

    • 60 tonnes obligation met in 2035 through recycling certificates

    • 30 tonnes (75% of 40) added to 2040 EPR target


Benefit: Incentivizes extending panel life, reducing overall waste generation while maintaining long-term accountability


Obligations of Recyclers


1. Registration and Authorization

Mandatory: Register on CPCB portal as solar PV recycler

Requirements:

  • Demonstrate technical capability and equipment

  • Provide facility details and processing capacity

  • Environmental clearances

  • Safety and pollution control measures


2. Material Recovery Standards

CPCB will mandate recovery rates (not yet finalized for solar PV specifically)

Expected Standards (Based on EU WEEE):

  • 85% recovery by weight (minimum)

  • 80% recycling (material actually made into new products)

Advanced facilities may target:

  • >95% total material recovery

  • >80% silver recovery

  • High-purity silicon suitable for semiconductor reuse


3. Record Keeping and Reporting

  • Maintain records of:

    • Panels received (type, quantity, source)

    • Processing methods used

    • Materials recovered (quantity, purity)

    • Materials sold (buyer, price)

  • File quarterly and annual returns on CPCB portal

  • Generate EPR certificates for producers


Environmental Compensation Regime

Two-Tier System:


Tier 1: EPR Target Non-Compliance

If producer fails to meet recycling targets:

Calculation: Environmental Compensation = (Target Shortfall in tonnes) × (Average Cost of Collection + Transportation + Recycling per tonne)

Purpose: Compensates for environmental damage from unrecycled waste

Example:

  • Target: Recycle 100 tonnes

  • Actually recycled: 70 tonnes

  • Shortfall: 30 tonnes

  • Average cost: ₹30,000 per tonne

  • Environmental Compensation: ₹9 lakh


Tier 2: RoHS and Other Violations

RoHS (Restriction of Hazardous Substances): New panels must not contain (beyond specified limits):

  • Lead: <0.1% by weight

  • Mercury: <0.1%

  • Cadmium: <0.01%

  • Hexavalent Chromium: <0.1%

  • Polybrominated biphenyls (PBBs): <0.1%

  • Polybrominated diphenyl ethers (PBDEs): <0.1%

Violations:

  • Non-compliance with storage guidelines

  • Improper disposal or landfilling

  • Dealing with unregistered entities

  • False reporting

Penalties:

  • Environmental compensation (amount varies by violation)

  • Prosecution under Environment (Protection) Act, 1986 (imprisonment up to 5 years, fine up to ₹1 lakh, or both)

  • Increased penalty for continuing violations


Comparison: India vs. Global Regulations


European Union (EU) - WEEE Directive

Strengths:

  • First to adopt PV-specific regulations (2012)

  • Mandatory 85% recovery rate by weight

  • Well-established collection infrastructure (PV CYCLE)

  • Producer financing requirement (must pay for collection/recycling)

Lessons for India:

  • Weight-based targets (85%) are easily met by recovering glass/aluminum but don't incentivize high-value material recovery

  • Need value-based or material-specific targets (e.g., silver recovery %)


United States

Status: No federal PV recycling policy

State-Level Actions:

  • Washington State: Manufacturers must finance recycling (2017)

  • California: Working on legislation

Weakness: Fragmented approach, most solar waste goes to landfills

Opportunity for India: Learn from U.S. gaps, implement comprehensive national framework


China

Approach:

  • Extended producer responsibility

  • Subsidies for recycling enterprises

  • National recycling capacity development targets

Challenge: Enforcement gaps, informal recycling sector persists

Parallel to India: Both countries face large informal sectors requiring formalization


Japan

Approach:

  • Voluntary industry initiatives

  • Government-supported R&D

  • Advanced recycling technology development

Strength: High-tech approaches achieving >95% material recovery

Lesson for India: Invest in R&D, don't just copy basic European technologies


India's Regulatory Gaps and Recommendations

Current Gaps:

  1. No EPR Targets Until 2035: 

    • 12-year delay may allow waste accumulation

    • Recommendation: Phased targets starting 2028 (even at 10-20% initially)

  2. Weight-Based vs. Value-Based Targets: 

    • If India adopts EU's 85% weight target, recyclers will only recover glass/aluminum

    • Recommendation: Separate targets for high-value materials (e.g., 75% silver recovery, 60% silicon recovery)

  3. Producer Responsibility Data Gaps: 

    • No clear mechanism for tracking panel lifespans and end-of-life projections

    • Recommendation: Mandatory panel serialization and registration similar to vehicle VINs

  4. Lack of Financial Mechanisms: 

    • EPR certificate market needs operationalization

    • Recommendation: CPCB-operated online trading platform with transparent pricing

  5. Inadequate Recycler Support: 

    • No capital subsidies or R&D grants specified

    • Recommendation: Ministry of New and Renewable Energy (MNRE) collaboration for green financing

  6. Enforcement Capacity:

Supply Chain Waste Mapping


Solar panel recycling isn't only about end-of-life panels. Significant waste is generated throughout the supply chain, often overlooked in policy discussions.

Manufacturing Waste

Sources:

  1. Silicon Wafer Production: 

    • Kerf loss: Up to 40-50% of silicon block lost during wire sawing into wafers

    • Broken wafers: 5-10% breakage during handling

    • Reject wafers: Quality control failures

Quantity: With India's push for domestic manufacturing (12 GW module capacity under PLI scheme), manufacturing waste could reach 10,000-15,000 tonnes annually by 2030


Current Handling:

  • Some manufacturers recycle kerf internally

  • Most sold as metallurgical-grade silicon

  • Opportunity: ICARUS project (Europe) developing processes to convert kerf to 4-5N purity for reuse in polysilicon production

  • Cell and Module Manufacturing: 

    • Defective cells: 2-5% rejection rate

    • EVA trimming waste

    • Backsheet offcuts

    • Failed lamination: Panels not meeting quality tests


Management:

  • Recyclers should co-locate with manufacturing facilities

  • Internal recycling loops reduce transportation costs

  • Immediate processing prevents material degradation


Installation and Transportation Damage


Sources:

  • Transit breakage: 1-3% of panels damaged during shipping

  • Installation damage: Dropped panels, improper handling

  • Commissioning rejects: Underperforming panels replaced during warranty period


Quantity: With 50-60 GW annual installations by 2030, 500-1,500 MW (approximately 15,000-45,000 panels or 500-1,500 tonnes) could be damaged waste

Challenge: These panels are scattered across installers, difficult to collect

Solution: EPR obligations should include installation waste, requiring installers to return damaged panels to manufacturers


Early Replacement and Repowering

Driver: Economics often favor early panel replacement

Scenarios:

  1. Technology Upgrade: 

    • Panels installed in 2015: 15-16% efficiency

    • Current panels: 22-24% efficiency

    • Investor may replace after 7-10 years to boost output

  2. Repowering for Tax Credits: 

    • In U.S., "repowering" a solar project qualifies for new Investment Tax Credit (ITC)

    • Occurs around year 12 of project

    • Panels operating fine but replaced for financial reasons

    • Does India have similar provision? Not yet, but could emerge

  3. Performance-Based Contracts: 

    • If panel underperforms, owner replaces for optimization

    • Panels at 85% efficiency replaced even though functional

Impact: Creates premature waste stream potentially 50 times larger than IRENA end-of-life projections (per Harvard Business Review analysis)

Policy Need: Tracking and managing early replacement waste; potentially taxing or regulating premature disposal


Mapping Tools and Data Systems


Current Gap: India lacks comprehensive waste mapping

Need:

  • Geographic Information System (GIS) mapping installation locations

  • Material flow analysis tracking panels from manufacture to end-of-life

  • Predictive modeling for waste generation by region/year

CEEW Proposal: Centralized solar inventory accessible to:

  • Recyclers (for plant location planning)

  • Policymakers (for infrastructure development)

  • Producers (for EPR compliance planning)

Technology: Blockchain-based tracking proposed for:

  • Panel serial numbers

  • Transfer of ownership

  • End-of-life reporting

  • Recycling certification

Benefit: Transparency, fraud prevention, optimized reverse logistics

  • Community acceptance (multiple green services)


Potential for India: Government promoting biorefineries; integrate solar recycling component


Common FAQ Section

Q1: Is solar panel recycling mandatory in India?

Answer: Yes, solar panel recycling is mandatory in India under the E-Waste (Management) Rules, 2022, which classify solar PV modules, panels, and cells as e-waste. Manufacturers, producers, and bulk consumers must register on the CPCB portal and ensure proper end-of-life management. Panels must be processed by CPCB-registered recyclers, and landfilling without treatment is prohibited.


Q2: How much does solar panel recycling cost in India?

Answer: Currently, solar panel recycling costs approximately ₹25,000-30,000 per tonne in India. For individual homeowners, this translates to roughly ₹600-750 per panel. However, under Extended Producer Responsibility (EPR) frameworks being implemented, manufacturers are expected to cover recycling costs through collection schemes, potentially making it free for panel owners in the future.


Q3: What materials are recovered from solar panel recycling?

Answer: Solar panel recycling recovers multiple valuable materials: glass (70-76% of panel weight), aluminum (8-10% from frames), copper (~1% from wiring), silicon (3-5% from photovoltaic cells), and silver (~0.02% but highly valuable). Advanced recycling processes achieve 90-95% total material recovery rates, with glass and aluminum being the easiest to recycle, while silicon and silver require specialized chemical processing.


Q4: Can recycled silicon be used in new solar panels?

Answer: Yes, but with purification. Recycled silicon can be used in new solar panels if purified to solar-grade quality (99.9999% purity or 6N). Current recycling processes achieve 85-96% silicon recovery, but most recovered silicon requires additional refining to meet solar cell manufacturing standards. Emerging technologies like upgraded metallurgical-grade silicon (UMG) processes are making solar-grade recycling more economically viable.


Q5: How long do solar panels last before recycling?

Answer: Solar panels typically last 25-30 years before needing replacement or recycling. Most manufacturers warranty panels for 25 years at 80-85% of original performance. Panels degrade at approximately 0.5-0.8% annually due to UV exposure, thermal cycling, and environmental factors. However, early replacement may occur after 12-15 years for technology upgrades or repowering projects.


Q6: Are solar panels toxic or hazardous?

Answer: Solar panels contain some hazardous materials requiring careful handling during solar panel recycling. Crystalline silicon panels contain lead (in solder of older panels), small amounts of cadmium, and silver. Thin-film CdTe panels contain cadmium (highly toxic). Proper solar panel recycling through certified facilities prevents these materials from leaching into soil and groundwater, which would occur if panels were landfilled improperly.


Q7: What happens if I throw solar panels in regular trash?

Answer: DO NOT dispose of solar panels in regular trash—this is illegal under India's E-Waste Rules, 2022. Improper disposal can result in heavy metals like lead and cadmium contaminating soil and groundwater, posing serious environmental and health risks. Violators face penalties including environmental compensation charges and potential prosecution under the Environment (Protection) Act, 1986 with fines up to ₹1 lakh and imprisonment up to 5 years.


Q8: Who is responsible for recycling solar panels in India?

Answer: Under Extended Producer Responsibility (EPR) provisions of India's E-Waste Rules, 2022, manufacturers and producers (importers/brand owners) are responsible for solar panel recycling. They must establish collection systems, fund recycling operations, and meet recycling targets (to be set post-2034). Panel owners should contact their panel's manufacturer or use CPCB-registered collection centers. Producers can meet obligations by purchasing EPR certificates from registered recyclers.


Q9: How many solar panel recycling plants does India need?

Answer: According to CEEW research, India will need approximately 300 solar panel recycling facilities by 2047 to manage an estimated 11 million tonnes of solar waste. This requires an investment of roughly ₹4,200 crore in recycling infrastructure. Currently (2024-2025), India has fewer than 10 pilot or small-scale facilities, indicating massive infrastructure development is needed over the next two decades.


Q10: Can broken or damaged solar panels be recycled?

Answer: Yes, broken and damaged panels are recyclable and often easier to process than intact panels. Physical damage doesn't affect material value—the glass, aluminum, copper, silicon, and silver remain recoverable. Mechanical recycling processes (crushing and separation) work effectively with broken panels. However, intact panels in good condition may have higher value through refurbishment or second-life markets before eventual recycling.


Q11: What's the difference between solar panel recycling and refurbishment?

Answer: Refurbishment extends a panel's operational life by repairing or replacing components (junction boxes, frames, damaged cells), adding 5-10 years of use. Solar panel recycling recovers raw materials from end-of-life panels through mechanical, thermal, and chemical processes. Under India's E-Waste Rules, refurbishers can generate certificates allowing producers to defer (not eliminate) EPR obligations, with 75% of deferred quantity eventually requiring recycling when the refurbished panel reaches final end-of-life.


Conclusion

Solar panel recycling stands at a critical juncture in India's renewable energy journey. As the nation races toward 500 GW of renewable capacity by 2030 and beyond, the looming challenge of 11 million tonnes of solar waste by 2047 demands immediate, coordinated action.


The technology exists—90-95% of a solar panel's materials are recoverable using proven mechanical, thermal, and chemical processes. The market potential is substantial—₹3,700 crore in material value, meeting 38% of domestic solar manufacturing needs, and avoiding 37 million tonnes of carbon emissions.

The regulatory framework is in place—the E-Waste (Management) Rules, 2022 provide the legal foundation through Extended Producer Responsibility and mandatory recycling protocols.


Yet, significant barriers remain. Solar panel recycling currently operates at a financial loss, with panel collection costs consuming two-thirds of total expenses. The informal sector offers competing channels for used panels. Infrastructure is nascent, with fewer than 10 operational facilities against a need for 300.

Technology must advance to achieve economically viable high-purity material recovery, particularly for silver and solar-grade silicon.


The path forward requires multi-stakeholder collaboration:

  • Policymakers must:

    • Operationalize EPR certificate trading through the CPCB portal

    • Provide fiscal incentives (subsidies, tax breaks) for recycling plant investments

    • Set value-based recycling targets (not just weight-based) to incentivize high-value material recovery

    • Establish the proposed Circular Solar Taskforce under MNRE to coordinate action

  • Industry must:

    • Design panels for easier recyclability (water-soluble encapsulants, frameless designs, lead-free solders)

    • Invest in collection infrastructure fulfilling EPR obligations

    • Fund R&D for breakthrough technologies (automated dismantling, advanced silver recovery, silicon purification)

    • Collaborate rather than compete—shared collection networks and processing facilities reduce costs

  • Researchers must:

    • Focus on India-specific solutions (low-cost processes suited to local conditions)

    • Develop mobile recycling units for remote solar installations

    • Improve silver recovery rates from current 70-80% to >95%

    • Demonstrate economically viable silicon purification to solar-grade

  • Financial institutions must:

    • Recognize recycling as strategic infrastructure deserving green financing

    • Offer low-interest loans and venture capital for plant development

    • Support pilot projects demonstrating technology and business model viability

  • Citizens and businesses must:

    • Dispose of panels responsibly through certified channels

    • Demand transparency from manufacturers on end-of-life plans

    • Support policy measures that may increase upfront panel costs but ensure lifecycle responsibility


The transformation from waste to wealth is possible. Europe's Veolia-PV CYCLE facility demonstrates 95% material recovery at commercial scale. First Solar's CdTe recycling achieves cost-neutral circular operations. Solar Materials in Germany claims economically viable recovery of all materials at solar-grade purity.


India has unique advantages—a growing domestic manufacturing sector creating opportunities for on-site waste processing, lower labor costs enabling economically viable manual dismantling, and government commitment to green industrialization providing policy tailwinds.


Solar panel recycling is not just an environmental imperative—it's an economic opportunity. It reduces import dependence on critical materials, creates green jobs across the value chain (estimated 10,000-15,000 direct jobs in recycling sector by 2040), and positions India as a leader in circular economy approaches to renewable energy.


The timeline is clear: Infrastructure must be built now, in the 2020s, before the waste wave arrives in the 2030s. Storage mandates provide a 12-year window until 2035, but this transition period must be used proactively, not passively.


The choice is stark: Act now to establish a thriving circular solar panel recycling industry, recovering billions in material value while protecting the environment, or face an accumulating waste crisis that undermines the very sustainability solar energy promises.

India's solar revolution can power a new green industrial opportunity. Recycling is the essential link in making this transition truly sustainable, resource-resilient, and economically self-reliant.


The time to act is now. The infrastructure, technology, and policy frameworks needed are within reach—what's required is collective will and coordinated action.
