MNRE proposes higher efficiency norms for ALMM solar modules

The Ministry of New and Renewable Energy has released a draft proposal to raise the minimum efficiency requirements for solar PV modules listed under the Approved List of Models and Manufacturers. The plan introduces phased standards from January 1, 2027 and tighter benchmarks from January 1, 2028.

The draft sets new thresholds for each application category. For utility and grid-scale plants under Category I, c-Si modules need to reach 21.0 per cent in 2027 and 21.5 per cent in 2028, compared to the current 20.0 per cent. CdTe modules need to move from 19.0 per cent to 20.0 per cent and then 20.5 per cent.

For rooftop and solar pumping systems under Category II, c Si modules must achieve 20.5 per cent in 2027 and 21.0 per cent in 2028, up from 19.5 per cent. CdTe modules need 19.5 per cent and 20.0 per cent over the same period, compared to 18.5 per cent at present.

For off grid applications under Category III, the requirement increases from 18.0 per cent to 19.0 per cent in 2027 and 19.5 per cent in 2028 for both c-Si and CdTe modules.

For other applications under Category IV, the c Si bar rises from 19.0 per cent to 20.0 per cent in 2027 and 20.5 per cent in 2028. CdTe modules move from 18.0 per cent to 19.0 per cent and then 19.5 per cent.

MNRE stated that the changes aim to ensure the ALMM reflects commercially viable high-efficiency products and supports domestic manufacturing of advanced modules. Modules already on the list that do not meet the new benchmarks will be removed when the revised norms are enforced.

The ministry has opened the draft for stakeholder comments until December 27, 2025.
