India's solar manufacturing industry is set for another major transformation. To strengthen domestic production and reduce dependence on imported components, the Ministry of New and Renewable Energy (MNRE) has proposed ALMM List-III, which will include solar wafers under the Approved List of Models and Manufacturers (ALMM) framework. The proposed changes, expected from June 1, 2028 after specific manufacturing conditions are met, aim to build a more integrated and self-reliant solar manufacturing ecosystem in India. In this article, we explain the proposed ALMM List-III in simple language, discuss why it matters, and explore how it could shape India's solar manufacturing companies over the coming years. What is ALMM? The Approved List of Models and Manufacturers (ALMM) is a framework introduced by the Ministry of New and Renewable Energy (MNRE) to ensure that government-supported solar projects use approved, high-quality solar products. Initially, ALMM covered only solar modules (List-I). Later, ALMM List-II was introduced for solar cells. Now, MNRE has proposed ALMM List-III to include solar wafers, expanding quality standards across more stages of the solar manufacturing process. This proposed expansion aims to strengthen India's domestic solar manufacturing ecosystem, improve product quality, and support the country's goal of becoming more self-reliant in renewable energy. Why Has MNRE Proposed ALMM List-III? India has significantly expanded its solar manufacturing capacity over the past decade, but many upstream components, especially solar wafers, are still imported. This creates challenges such as supply chain disruptions, price fluctuations, and dependence on global markets. To address these issues, MNRE has proposed ALMM List-III to encourage domestic wafer manufacturing and strengthen India's solar value chain. The proposal aims to: Promote local production of solar wafers. Encourage investment in integrated manufacturing facilities. Reduce dependence on imported components. Improve supply chain security and product quality. Support the Make in India initiative. Strengthen India's renewable energy and energy security goals. By extending the ALMM framework beyond modules and cells, the proposal focuses on improving quality and reliability from the early stages of solar manufacturing. Understanding the Solar Manufacturing Process To understand the importance of ALMM List-III, it's helpful to know how a solar panel is manufactured. The production process involves several stages, with each one contributing to the efficiency and reliability of the final solar module. Manufacturing Process: Quartz → Polysilicon → Ingot → Wafer → Solar Cell → Solar Module → Solar Power System Stage Description Quartz A naturally occurring mineral rich in silicon, used as the starting material. Polysilicon Quartz is refined into high-purity polysilicon, the primary raw material for solar cells. Solar Ingot Polysilicon is melted and moulded into solid ingots. Solar Wafer Ingots are sliced into ultra-thin wafers, which serve as the base for solar cells. Solar Cell Wafers are processed into photovoltaic cells that convert sunlight into electricity. Solar Module Multiple solar cells are connected and assembled into durable solar panels for residential, commercial, industrial, and utility-scale applications. Since solar wafers are a key component in this process, the proposed ALMM List-III aims to improve quality standards and strengthen India's domestic manufacturing ecosystem from the upstream stage itself. Why Are Solar Wafers So Important? Solar wafers are one of the most important components in the photovoltaic (PV) manufacturing process. Their quality directly affects the performance, efficiency, and durability of a solar panel. High-quality solar wafers help improve: Solar cell efficiency Power output Long-term reliability Manufacturing yield Overall module performance As advanced technologies like TOPCon Solar and other high-efficiency solar cells become more common, precision wafer manufacturing is becoming increasingly important. By including solar wafers in the proposed ALMM List-III, MNRE aims to strengthen quality standards and support the growth of India's domestic solar manufacturing companies. What Will Change Under the Proposed ALMM List-III? The proposed ALMM List-III introduces a new level of compliance for solar wafer manufacturers supplying products for eligible government-supported solar projects. Once implemented, the ALMM framework will cover three major stages of solar manufacturing: ALMM List Covers Purpose List-I Solar Modules Approved module manufacturers List-II Solar Cells Approved cell manufacturers List-III (Proposed) Solar Wafers Approved wafer manufacturers This means future ALMM-compliant solar modules will be expected to use approved cells as well as approved wafers for applicable projects. The proposal represents India's gradual transition towards a fully integrated domestic solar manufacturing ecosystem. When Will ALMM List-III Become Effective? The proposed ALMM List-III is expected to take effect from June 1, 2028, but only after specific manufacturing conditions are met. According to the proposal, the following requirements must be fulfilled before the new framework is implemented: At least three independent solar wafer manufacturers must be enlisted. The manufacturers must not have common ownership or control. Their combined manufacturing capacity should be at least 15 GW per year. They must also have equivalent solar ingot manufacturing capacity. These conditions are designed to ensure that India has sufficient domestic manufacturing capacity before ALMM List-III is officially implemented. Key Highlights of the Proposed ALMM List-III The proposed ALMM List-III introduces several important changes to strengthen India's solar manufacturing ecosystem: Inclusion of Solar Wafers: Solar wafers will be covered under the ALMM framework for the first time, extending quality standards beyond modules and cells.
