MNRE Proposes Higher Efficiency Standards For Solar PV Modules To Boost Quality And Performance

The Government of India, through the Ministry of New & Renewable Energy (MNRE), has proposed a significant increase in the minimum efficiency standards for solar PV modules under the Approved List of Models & Manufacturers (ALMM) List-I. This move is intended to ensure that government projects use only the most efficient and commercially viable solar technologies, keeping older, lower-efficiency modules out of the market. The proposal sets a phased approach, with new standards to come into effect from January 1, 2027, and January 1, 2028.

Currently, crystalline silicon (c-Si) modules used in utility or grid-scale projects must have a minimum efficiency of 20.0%, while Cadmium Telluride (CdTe) modules are required to meet 19.0%. Under the new draft order, c-Si modules in utility applications would need to reach 21.0% by 2027 and 21.5% by 2028. CdTe modules for the same category would require 20.0% efficiency in 2027, increasing to 20.5% in 2028.

The proposed increase applies across all solar application categories. For rooftop and solar pumping projects, c-Si modules currently require 19.5% efficiency, which would rise to 20.5% in 2027 and 21.0% in 2028. CdTe modules in these applications, presently at 18.5%, would need to achieve 19.5% and then 20.0% over the same period. Even smaller, off-grid projects, often referred to as DRE projects with modules under 200 Wp, will see requirements for both c-Si and CdTe modules increase from 18.0% today to 19.0% in 2027 and 19.5% in 2028.

The draft also includes a key condition for existing manufacturers. Any modules currently listed in the ALMM or those that gain enlistment but do not meet the revised efficiency thresholds will be removed from List-I when the new standards take effect. This step aims to ensure compliance and encourage manufacturers to produce or supply only higher-efficiency modules.

The MNRE has released this draft for stakeholder consultation, inviting comments, suggestions, and feedback from industry participants. The deadline for submissions is December 27, 2025. This initiative reflects the government’s commitment to improving quality and efficiency standards in India’s expanding solar energy sector, promoting the adoption of advanced solar technologies in the country.
