India’s enforcement of ALMM List-II has led to a 98% crash in Chinese solar cell imports as of August 2026. While the policy aims to boost domestic manufacturing, a significant gap between cell production capacity and module assembly is creating supply chain bottlenecks. Investors should track project execution timelines and domestic capacity expansion as the industry approaches the critical December 31, 2026, exemption deadline.
The Indian solar energy sector is navigating a major shift in its supply chain following the strict enforcement of the Approved List of Models and Manufacturers (ALMM) List-II. Industry data indicates that Chinese solar cell imports into India, which were previously a mainstay for the sector, collapsed by 98% between April and August 2026. This decline is a direct result of the government’s push to ensure that solar projects—specifically those backed by the government, open-access, and net-metering schemes—prioritize domestically produced cells.
The policy, which became effective on June 1, 2026, acts as a protective shield for Indian manufacturers. By restricting the flow of cheaper imported cells, the government intends to incentivize local firms to scale up their production facilities. However, this transition has introduced a structural challenge. While India has rapidly expanded its domestic cell manufacturing capacity to approximately 37.8 GW as of October 2026, it remains insufficient to feed the country’s significantly larger solar module production base. This disparity creates a bottleneck where module makers may struggle to find enough locally produced cells to maintain their operational pace.
For project developers and EPC (Engineering, Procurement, and Construction) companies, this supply constraint brings new operational risks. If domestic manufacturers cannot scale production fast enough to meet the demand, the result could be delayed project commissioning and increased procurement costs. Because cells are the most critical component of a solar module, any shortage directly impacts the delivery schedule of large-scale solar parks.
The market is currently working within a transition phase. Regulations allow for a temporary exemption for certain net-metering and open-access projects, permitting them to use non-ALMM cells provided they are commissioned by December 31, 2026. This date is a key monitorable for the industry, as it marks the point when the full weight of the ALMM mandate will apply to these segments as well.
For investors, the long-term potential of the domestic solar manufacturing sector is clearer, but the short-term landscape is defined by this capacity mismatch. The success of this policy pivot will depend on how quickly domestic firms can bridge the gap between their cell production and the surging demand for modules. Investors and industry participants will likely watch the monthly output numbers, the progress of upcoming manufacturing plant expansions, and any revisions to timelines as the industry approaches the year-end deadline.
