Despite government policies like the ALMM to boost local production, India's solar sector spent $1.86 billion on imported cells in the last year. This reliance persists as companies still source critical machinery and wafers from China. For investors, the long-term profitability of Indian solar manufacturers remains tied to their ability to reduce these input costs through better technology and domestic scaling.
India’s solar manufacturing industry is navigating a difficult phase as it balances strong demand with a persistent need to import critical components. While policies such as the Approved List of Models and Manufacturers (ALMM) were designed to encourage domestic production, the sector continues to rely heavily on international suppliers, particularly from China. Recent data shows that even with mandates for locally made modules, imports of solar cells surged by 37% to reach $1.86 billion during the last year.
The Challenge of Input Costs
The current regulatory roadmap creates a staged transition toward local manufacturing. While ALMM-I mandated domestic modules, the subsequent ALMM-II, which became effective in June, requires the use of locally produced cells. However, this has shifted the pressure to the next stage of the supply chain. Manufacturers are now forced to import wafers—the thin slices of silicon used to make cells—as well as the specialized machinery required for production. This dependency is set to evolve further by June 2028 under ALMM-III, which aims to mandate local production of wafers and ingots for half of all domestic solar installations.
Why Cost Parity Remains Difficult
Competing directly with Chinese manufacturers presents a significant financial hurdle. The Chinese solar industry benefits from immense economies of scale and long-standing government support. In 2024, the Chinese solar sector recorded a collective loss of $60 billion, as major global players like JinkoSolar, Trina Solar, and Longi Green prioritized market share over immediate profitability. Indian firms, which operate under different capital structures and cost pressures, find it difficult to match these aggressive pricing levels, which can put pressure on their own profit margins when they compete for the same utility-scale projects.
Investing in Future Technology
To break this cycle of dependency, industry experts point toward research and development as the primary solution. Rather than trying to compete solely on the cost of traditional silicon modules, Indian companies have an opportunity to lead in next-generation technologies. This includes 'evolutionary' advancements like using copper instead of silver for metallization or developing ultra-thin wafers to save on material costs. Further, 'revolutionary' R&D into perovskite-silicon tandem cells could allow India to leapfrog current standards.
However, funding remains a critical monitorable for investors. Annual government spending on solar research has historically been limited, with the Ministry of New and Renewable Energy reporting approximately ₹111 crore in investment since 2017. Industry analysts suggest that earmarking a portion of the customs duties collected on solar imports—which could generate up to ₹7,000 crore this year—might provide the necessary capital to bridge the gap between laboratory innovation and commercial-scale manufacturing. Investors should track future government announcements regarding the allocation of these funds, as they will directly influence the speed at which Indian companies can scale their technological capabilities and reduce reliance on expensive imports.
