Solar photovoltaic panels. India's installed solar fleet has grown more than fourfold since 2019, on 25–30-year hardware that is what turns today's small waste stream into a multi-million-tonne one. Source: Noggen13, Wikimedia Commons, CC BY-SA 4.0.

Two separate documents inform this piece, from different points in time, and their headline waste-volume numbers should not be read side by side as if they were measuring the same thing. The older one — "PV Waste Management in India: Comparative Analysis of State of Play & Strategic Recommendations for Extended Producer Responsibility (EPR)," produced by the EU-India Technical Cooperation Project together with SolarPower Europe, PV CYCLE and the National Solar Energy Federation of India (NSEFI) — is very likely the same report the Global Solar Council and NSEFI's own site record as launched on 26 March 2021 at the Solar India Expo, though this piece could not directly compare that PDF's full text against the slide excerpts it worked from, so treat the date as highly probable rather than certified. That report modelled cumulative PV module waste through 2030 in three scenarios: 11 kilotonnes (kt) low, 21 kt medium (steady 20% annual growth), and 34 kt high (if National Solar Mission targets were hit) — explicitly flagging that these are mostly early-life failures (transport damage, installation damage, "infant failures" in year one, assumed at a 0.1% rate) rather than end-of-life volume, since the bulk of India's fleet, installed from 2010 onward on 30-year modules, wasn't due to retire yet. As of the report's own 2019/2020 snapshot, India had roughly 35 GW AC installed, with ground-mounted utility-scale plants already 90% of the market — meaning most future waste was always going to be a B2B, utility-scale problem, not a residential rooftop one.

The newer document, CEEW's "How Much Does it Cost to Recycle a Solar Module in India?" (Ajinkya Kale and Akanksha Tyagi, November 2025), projects 11,221 kt — roughly 11.2 million tonnes — of cumulative solar waste by 2047. That is a wildly bigger number than 34 kt, but it is not describing the same thing: a longer horizon (2047 vs 2030), a much larger installed base to draw the projection from, and, in all likelihood, a different waste-generation methodology. The scale of the base fleet alone explains most of the gap: India's installed solar capacity has grown from that ~35 GW AC snapshot in 2019/2020 to roughly 164.6 GW as of 31 July 2026, per capacity data attributed to the Ministry of New and Renewable Energy (MNRE) and reported by SolarQuarter in August 2026 — a more than fourfold increase in under seven years, split (per the same figures) into 122.6 GW ground-mounted, 30.7 GW grid-connected rooftop, 4.8 GW hybrid-project solar and 6.5 GW off-grid. Separate MNRE data placed before Parliament put installed solar capacity at 162.15 GW in a slightly earlier snapshot the same year. Whichever exact figure is used, a fleet this size, on 25–30-year hardware, is what turns a 2021 report's 34 kt "high scenario" for 2030 into a 2025 report's 11,221 kt cumulative figure for 2047 — not a contradiction between the two reports, just two different measurements of a curve that has genuinely gotten much steeper since 2021.

CEEW's report lays out two competing recycling processes, and neither currently earns money. P1 (Mechanical) disassembles the module, shreds it, and separates materials electrostatically — cheap and simple, but it produces low-purity output and recovers no silver at all. P2 (Chemical) adds pyrolysis, nitric-acid leaching and hydrofluoric-acid etching to get high-purity recovered materials, including pure silver, but at meaningfully higher operating cost and with hazardous waste of its own to manage.

Figures per CEEW, "How Much Does it Cost to Recycle a Solar Module in India?" (Kale & Tyagi, Nov 2025). Revenue sub-splits by material (aluminium, glass, copper/silicon, and — for P2 only — silicon at ₹6,030/tonne and silver at ₹4,253/tonne) are read off a chart in the source deck and are approximate; the totals above are the report's own stated figures.

The table's shape is the whole story: waste procurement costs exactly the same, ₹27,300 per tonne, in both pathways, and it is by far the largest single line item — 56–68% of recurring cost. P2 recovers 23% more revenue than P1 thanks to silicon and silver recovery, but its processing cost is nearly double P1's, so the extra revenue doesn't close the gap; it just produces a slightly bigger loss. In other words, the losing variable in this business is not the chemistry, it's the price of the input. CEEW separately describes today's recycling cost, at ₹4.11–5.02 per watt, as roughly a quarter of the cost of a brand-new module — a genuinely useful reference point for policymakers thinking about embodied-material value, but not the same claim as "recycling is profitable": that per-watt figure is a cost of processing, not a margin, and the per-tonne numbers above are what actually determine whether a recycler survives.

The 2021 report's description of India's regulatory gap was accurate for its time: the E-Waste (Management) Rules of 2016 covered only IT/telecom and consumer electronics and explicitly excluded PV modules; the Solid Waste Rules applied to domestic waste, not industrial; the Hazardous Waste Rules didn't classify crystalline-silicon (c-Si) modules — the overwhelming majority of India's installed fleet — as hazardous waste under Schedule II Class A leaching thresholds. That left PV waste falling by default into a generic "Industrial Solid Waste" bucket, disposal responsibility resting with the developer, with no extended producer responsibility (EPR) mechanism at all. Thin-film (CdTe) modules, a small share of the market, were flagged as a separate case that could exceed hazardous cadmium thresholds. The report's own worked example of the leakage risk was solar glass: it contains antimony for UV stability, which is safe while the glass is intact but can leach into soil and groundwater if crushed in an uncontrolled landfill — the report's central argument for a landfill ban as the minimum first step.

That gap has since been partly, not fully, closed. The Ministry of Environment, Forest and Climate Change replaced the 2016 rules with the E-Waste (Management) Rules, 2022 — notified 2 November 2022, in force from 1 April 2023 — and added a dedicated Chapter V covering solar photovoltaic modules, panels and cells for the first time. Per a Rajya Sabha statement from the then-Minister of Power and New & Renewable Energy, R.K. Singh, and secondary trade coverage of it (SolarQuarter, 16 March 2023), every manufacturer and producer of solar PV modules, panels or cells must now register on the government's E-Waste Management System portal, maintain a distinct inventory of what they've placed on the market, file annual returns, and store the waste generated up to the 2034-35 financial year under storage-and-handling standards to be issued by the Central Pollution Control Board (CPCB); recyclers, separately, must recover materials to CPCB's specifications. A narrower, easily-confused amendment followed in March 2023: it exempted small amounts of cadmium and lead inside new solar panels/cells from the Rules' general restricted-substances schedule (a RoHS-type provision about what a module is allowed to contain) — a different question from the storage-and-recycling mandate above, and worth not conflating with it.

What that Chapter V mandate does not do is put solar PV on the same footing as the rest of e-waste. General e-waste categories under the 2022 Rules carry escalating, numeric EPR recycling targets; solar PV waste is explicitly exempt from those targets. Its obligation is registration, inventory, reporting and storage — not a percentage-of-volume recycled each year. CPCB's own operational guidance for what that storage actually has to look like took nearly three more years to arrive: a draft "Guidelines for Storage and Handling of Waste Solar Photovoltaic Modules or Panels or Cells" was released around 4 June 2025 (per Mercom India, Down To Earth and Outlook Business's coverage) and finalised around March 2026 (per SolarQuarter and AL Circle), specifying covered, dry, ventilated storage on impervious, non-leachable flooring, stacking limited to 20 layers or 2 metres, covered-truck transport, hand-over only to registered recyclers, and mandatory producer take-back/collection mechanisms. This piece could not fetch CPCB's or PIB's own text directly — every attempt to reach pib.gov.in, cpcb.nic.in, mnre.gov.in and most Indian and international news domains was blocked by this session's network egress policy — so everything above rests on multiple, independently-worded but mutually consistent secondary trade-press accounts of the same primary documents, not on this piece's own reading of the gazette notification or CPCB circular. Readers who need the primary text should pull the E-Waste (Management) Rules, 2022 and CPCB's guideline document directly.

Put plainly: CEEW's November 2025 line that "storage is mandated until 2034-35" is not a stray footnote about a distant deadline nobody has thought through — it is, as best this piece can verify, the literal substance of the operative rule, more than three years after solar PV waste formally entered e-waste law and still centred on holding the waste rather than processing it. That is exactly why CEEW's own top policy recommendation is to mandate EPR collection-and-recycling targets starting in 2027, rather than waiting for the 2034-35 storage window to run out on its own.

CEEW's model identifies three "levers," plus a fourth mechanism it calls the single most effective intervention available.

Procurement cost. The current market rate for acquiring a waste module runs around ₹600/module, which the report's own chart places inside a "loss zone." P1 breaks even at an assumed procurement cost of ₹375/module; P2 at ₹330/module. Closing that gap is less a technology problem than a market-structure one: it implies building a functioning, below-market-price waste-acquisition channel — plausibly through mandated hand-over from developers and insurers rather than open bidding — not a better shredder.

The TOPCon effect. Today's modules carry roughly 6–10 mg of silver per watt; newer, higher-efficiency TOPCon-type cells carry 20.4–26 mg/W. Because only P2 (Chemical) recovers silver at all, a waste stream dominated by high-silver TOPCon modules could flip its economics to a net profit of ₹1,125/tonne, per CEEW's model. This is real but distant: TOPCon modules being installed now won't become waste for roughly 25–30 years, which is why CEEW's own roadmap places this shift in a 2028–2035 "Acceleration" phase, not the near term. P1 gets nothing from this lever, since mechanical processing was never designed to recover silver.

Logistics clusters. The report's base case assumes a 360km collection radius for gathering waste modules. Optimising to a 100km radius could cut recurring costs by roughly 8% (₹3,217/tonne), concentrated around the states that already dominate utility-scale solar — Rajasthan, Gujarat, Maharashtra, Karnataka and Tamil Nadu — which tracks Report 2's earlier point that future waste is overwhelmingly a ground-mounted, B2B phenomenon. CEEW's recommendation is for State Industrial Development Corporations to allocate land specifically for these recycling clusters.

EPR-certificate trading. India's existing EPR-certificate market lets producers buy tradeable compliance credits from certified recyclers, but per CEEW's account, that trading is currently limited to certain "general e-waste metals" and does not cover copper, silver or silicon recovered specifically from solar modules. CEEW models that expanding certificate-trading scope — first to copper and aluminium, later to silver and silicon — could turn P2's current ₹12,341/tonne loss into a modelled net benefit of ₹24,659/tonne, which the report calls the single most effective intervention on the table. None of the four levers above is reflected in the storage-focused rule described in Section 3; that is the actual policy gap this piece is describing — not an absence of ideas, but ideas that haven't yet been written into the operative regulation.

Report 2's own decision matrix, comparing three policy options for who pays and who's responsible, is worth setting out because India's actual 2022 rules land in an unusual, fourth position relative to it.

Matrix per "PV Waste Management in India" (EU-India TCP / SolarPower Europe / PV CYCLE / NSEFI). "Pay-as-you-put" means financing this year's implied future waste immediately, via a fee added at point of sale, versus the report's explicitly rejected "pay-as-you-go" model, which would raise almost nothing today while volumes remain low.

India's actual 2022 rules don't map cleanly onto any of these three: responsibility has shifted toward the producer (registration, inventory, take-back obligations sit with manufacturers, closer to Option C), but the financing question the report treats as central — a visible fee, collected and ring-fenced now, against waste that may not surface for another 25 years — isn't resolved by a storage mandate at all. Storage defers the disposal decision; it doesn't fund the eventual recycling. That gap is visible in the industry's own preferences: 80% of stakeholders surveyed for Report 2 said manufacturers were willing to take on end-of-life responsibility, and 90% said they preferred an industry-led Producer Responsibility Organisation (PRO), modelled on the EU's PV CYCLE, over individual company schemes — though this piece could not locate the survey's sample size or methodology, and flags those figures as reported, not independently verified.

On-the-ground activity is real but small. Poseidon Solar has run a mechanical-shredding pilot plant in Gummidipoondi, Tamil Nadu, since it became fully operational in September 2020, processing up to 2.5 tonnes a day — a working, if modest, P1-style line that predates most of the regulation discussed above, per Recycling International's coverage of India's broader push (which also cites an official ambition, since apparently unmet at this scale, of reaching 150 tonnes/day of national capacity by May 2022). More recently, Attero Recycling — an established e-waste and battery recycler — signed an MoU with the National Institute of Solar Energy (NISE, an MNRE body) around April 2025 to jointly develop and pilot solar-panel recycling technology, per pv magazine India and Renewable Watch's coverage, and the company was later recognised with a "Circular Economy Icon in Solar Panel Recycling" award at the Uttar Pradesh Energy Expo in May 2026, per SolarQuarter's event coverage. That is a formal move into solar-specific R&D, not confirmed commercial-scale capacity. Search coverage tied Lohum specifically to battery, not solar, recycling; no confirmed solar-panel-specific recycling line was found for Cerebra, Waaree, Eco Recycling or Exigo in this research pass, and one source described RE Sustainability Limited as positioned to extend its existing hazardous-waste network into solar PV "as mandates tighten" — a forward-looking claim, not evidence of an operating facility. None of this should be read as a complete map of Indian solar-recycling capacity; it is what turned up in a search pass conducted under this session's network restrictions.

The two reports' own roadmaps converge on the same instinct even though they're built independently: CEEW's three phases run Mobilisation (now–2027: pilot EPR targets, R&D for solar-grade silicon, cluster identification) → Acceleration (2028–2035: TOPCon waste enters the stream, EPR-certificate trading active for all metals) → Circularity (2035–2047: full-scale processing, 60% of silicon demand met domestically). Report 2's three phases run Immediate (landfill ban, industry self-regulation, EPR framework legislation) → System Maturity (operationalise the "pay-as-you-put" fee, stand up the industry PRO) → Innovation (eco-design standards, joint EU-India R&D). Both, in their own vocabulary, are arguing against waiting for the 2034-35 storage window to force the issue.
