New Delhi: The ALMM framework for solar ingots and wafers has been extended by India’s Ministry of New and Renewable Energy (MNRE), marking a major policy step to strengthen the country’s renewable energy supply chain. Starting June 1, 2028, solar projects will be required to use domestically approved wafers and ingots under the Approved List of Models and Manufacturers (ALMM).
This move aims to reduce import dependence, improve quality control, and build a fully integrated solar manufacturing ecosystem in India. The decision aligns with the government’s broader goal of achieving energy security and self-reliance in clean energy technologies.
What is the ALMM Framework
The Approved List of Models and Manufacturers (ALMM) is a government mechanism that allows only approved domestic manufacturers to supply solar components for government-backed projects.
- ALMM List-I: Solar modules
- ALMM List-II: Solar cells
- ALMM List-III (new): Solar wafers (and linked ingots)
This ensures quality, traceability, and reliability across the solar supply chain while supporting Indian manufacturers.
Details of ALMM Framework Extension
From June 1, 2028, the ALMM framework will expand upstream to include:
- Solar wafers (thin silicon slices used in cells)
- Solar ingots (raw semiconductor blocks used to make wafers)
This means:
- Modules must come from ALMM List-I
- Cells must come from ALMM List-II
- Wafers must come from ALMM List-III
Mandatory Domestic Sourcing
After implementation:
- Only ALMM-approved wafers and ingots can be used in eligible projects
- Non-compliance may lead to removal from approved lists
This creates a complete domestic value chain from ingot → wafer → cell → module.
Conditions Before Implementation
The policy will come into force only if:
- At least 3 independent wafer manufacturing units are operational
- Combined capacity reaches 15 GW per year
- Manufacturers have matching ingot production capacity
Exemptions and Transition Rules
- Projects with earlier bid deadlines may be exempt
- Projects already exempt from solar cell rules will also be exempt from wafer rules
- Some rooftop, open-access, or older projects may have phased compliance
What is the Importance of ALMM Framework Extension
India currently relies heavily on imports (especially from China) for wafers and ingots. This policy aims to:
- Cut imports
- Strengthen domestic manufacturing
Boost ‘Make in India’ in Solar
The move supports:
- Local industry growth
- Job creation
- Investment in high-tech manufacturing
Strengthen Energy Security
By controlling the full supply chain, India ensures:
- Stable supply
- Better quality control
- Reduced global dependency
Support Renewable Energy Targets
India is rapidly expanding solar capacity. A strong domestic ecosystem will help achieve:
- Net-zero targets
- Long-term sustainability goals
What is the Impact of ALMM Framework Extension
The extension of ALMM to wafers and ingots is seen as a game-changing reform.
- Encourages backward integration in solar manufacturing
- Gives early investors an advantage
- Positions India as a global solar manufacturing hub
Experts believe this policy will create a self-reliant solar ecosystem by 2030, aligning with India’s clean energy ambitions.
