Recycling of Solar Panels: Process, Industry Landscape, and Facility Ecosystem in India

Key Summary

India’s rapid scale-up of solar energy capacity—driven by decarbonization commitments, energy security priorities, and policy incentives—has created a parallel sustainability imperative: managing photovoltaic (PV) panel waste. Solar panels typically have a lifespan of 20–30 years; however, early replacements, manufacturing defects, and weather damage are already generating end-of-life (EoL) waste streams. As India moves toward its ambitious renewable capacity targets, solar panel recycling is transitioning from a niche environmental activity into a strategic circular-economy industry.

This article examines the solar panel recycling process, evaluates the current and emerging recycling facilities in India, and highlights market, regulatory, and technology dynamics shaping the sector.

1. Solar Panel Waste: Scale of the Emerging Challenge

India is among the fastest-growing solar markets globally. With gigawatts of capacity installed annually, cumulative waste is projected to surge in the 2030s when early installations retire. Despite this trajectory, infrastructure readiness remains limited.

Industry assessments highlight three structural gaps:

  • Regulatory vacuum: PV waste is not comprehensively covered under India’s e-waste rules.

  • Lack of Extended Producer Responsibility (EPR) mandates.

  • Limited recycling infrastructure and awareness.

As of the mid-2020s, large-scale commercial recycling capacity has been minimal, underscoring the urgency for investment and policy action.

2. Solar Panel Recycling Process: Step-by-Step Value Recovery

Solar panel recycling aims to recover high-value materials such as glass, aluminum, silicon, copper, and silver. Modern recycling integrates mechanical, thermal, and chemical processes.

GHG accounting and its emission factors

By -
Greenhouse Gas (GHG) Accounting involves quantifying emissions across different scopes (Scope 1, Scope 2, and Scope 3) and is typically guided by protocols such as the Greenhouse Gas Protocol. Here are the key formulas and approaches used in GHG accounting for each scope: 1. Scope 1: Direct Emissions Scope 1 includes direct emissions from sources owned or controlled by the organization (e.g., fuel combustion in company-owned vehicles, emissions from manufacturing processes). Formula for Combustion Emissions For fossil fuel combustion: Emissions = Activity Data × Emission Factor \text{Emissions} = \text{Activity Data} \times \text{Emission Factor} Emissions = Activity Data × Emission Factor Activity Data : Quantity of fuel used (e.g., liters of diesel, cubic meters of natural gas). Emission Factor : A coefficient that represents the emissions produced per unit of activity (e.g., kg CO₂ per liter of diesel). Example (CO₂ emissions from fuel): CO₂ Emissions = Fuel...

Deviation Settlement Mechanism (DSM) guidelines 2024

By -
As per the latest Deviation Settlement Mechanism (DSM) guidelines from the Central Electricity Regulatory Commission (CERC), DSM charges are defined based on grid stability needs, particularly regarding frequency deviation and renewable energy dynamics. The charges vary depending on the deviation percentage from the target frequency range (49.90 Hz to 50.05 Hz), with penalties scaling for larger deviations. For renewable-rich and super renewable-rich states (based on their installed wind and solar capacity), CERC allows greater flexibility in permissible deviation limits on the demand side. This aims to balance the grid challenges posed by variable renewable generation. States with renewable capacities between 1 GW and 5 GW are considered renewable-rich, while those with over 5 GW are super renewable-rich. Stand-alone energy storage systems (ESS) are subject to similar DSM charges as general sellers, but ESS paired with renewables like wind and solar follow specific volume limits for o...

What if AI predicted equipment failures with 100% accuracy ? [20]

By -
Imagine an electricity system where every impending asset failure is known in advance with perfect precision —time, location, cause, and cascading effects—across transmission, distribution, generation, and behind‑the‑meter devices. In such a world, outages from equipment defects disappear, capital plans re‑optimize around true residual life , spares and crews arrive “just in time,” and regulators recalibrate reliability incentives from SAIDI/SAIFI to assurance of supply under probabilistic risk that excludes random equipment faults. The International Energy Agency (IEA) already frames digitalization as essential to grid reliability and cost control; with perfect prediction, the gains would multiply—reducing outage minutes, deferring capex, and accelerating the clean‑energy transition by unlocking grid headroom without overbuilding . [iea.org] , [iea.org] Evidence from real utilities shows that even non‑perfect predictive analytics deliver 10–20% OPEX savings and 40–60% capex optim...

Why the dislike button is removed in all the social media platforms?

By -
 The removal or absence of a dislike button on most social media platforms can be attributed to several reasons, primarily centered around user experience, mental health, and the dynamics of online interactions. Here's a detailed explanation: 1. Preventing Negativity and Harassment A dislike button could encourage negative behaviors, such as trolling or bullying. Users might use it to target individuals or content creators, leading to a toxic environment. Platforms aim to promote constructive engagement rather than actions that might demoralize users. 2. Mental Health Concerns Social media companies are increasingly aware of the impact their platforms have on mental health. Visible indicators of disapproval could harm users' self-esteem and lead to stress or anxiety, especially for younger or vulnerable audiences. 3. Focus on Constructive Feedback Platforms encourage users to give feedback in a constructive manner, such as through comments or reporting inappropriate content. A...
