Solex Energy’s plan to build solar module and cell manufacturing capacity in the United States is more than an overseas expansion proposal. It also highlights a structural imbalance within India’s renewable-energy supply chain: the country has reported module manufacturing capacity of about 262 GW, but cell capacity of only around 37 GW as of October 2026.
The Gujarat-based company is considering US investments as part of a $1.5 billion roadmap through 2030, according to Chairman and Managing Director Chetan Shah. The company currently operates a 4 GW module manufacturing facility in Gujarat and plans to raise its module capacity to 10 GW. It is also establishing 10 GW of cell manufacturing capacity and 2 GW of ingot and wafer production.
The proposed US facilities have not yet been detailed. Shah told PTI that the company is studying possible locations, investment requirements and other parameters. He did not disclose project specifics, citing regulatory compliance. The immediate announcement, therefore, is not a confirmed construction schedule or a finalised investment commitment in the US. It is an expansion plan being evaluated within a larger corporate investment programme.
Its significance lies in the supply-chain choices behind solar deployment. Solar modules are assembled from cells, while cells depend on upstream inputs such as wafers and ingots. A large module-making base without a comparable cell-manufacturing ecosystem can leave manufacturers dependent on limited domestic supplies or imports. Shah’s comments place that imbalance at the centre of the company’s argument for expanding across more stages of production.
The mismatch is considerable on the figures cited by the company chairman. India’s reported module manufacturing capacity is about seven times its cell capacity. But capacity figures do not automatically represent operational output. Shah said much of the installed module capacity consists of older mono PERC technology and that several facilities are non-operational. He also said newer module capacity has been established for TOPCon technology.
This distinction matters because nominal capacity can conceal the usable strength of an industrial system. A factory that is installed but inactive does not contribute to current supply. Similarly, a facility built around an older technology may not serve manufacturers or project developers seeking newer products. The information supplied by Solex does not provide utilisation rates, production volumes or a technology-wise breakdown of operating plants, so the precise scale of the effective capacity gap cannot be established from the available data.
The company’s US strategy is linked to both demand and trade conditions. Shah described the United States as the largest global solar market and said steep anti-dumping duties on Chinese imports leave India as the sole viable supplier of low-cost alternatives. He said Solex is seeking to use the US market’s demand for clean-energy components while positioning itself as a cost-effective alternative to Chinese suppliers.
That positioning reflects how solar manufacturing is increasingly shaped by trade policy as well as by energy demand. For manufacturers, the location of a plant affects market access, compliance requirements and the commercial viability of exports. Solex’s proposed US study therefore sits at the intersection of industrial policy, international trade and the physical infrastructure needed to produce low-carbon energy equipment.
For India, the more immediate policy question is domestic. Shah said the industry is aligned with the government’s objectives under the ALMM-II framework and has invested thousands of crore in module capacity to support the country’s net-zero goals. He nevertheless called for an extension of ALMM-II by at least 12 months, citing the availability of cells under current market conditions.
The Approved List of Models and Manufacturers framework requires the sourcing of made-in-India cells from an approved list of module manufacturers, as described in the supplied report. The policy is intended to connect the growth of solar deployment with domestic manufacturing. However, the industry’s reported capacity figures show the difficulty of enforcing a domestic sourcing requirement when the upstream cell base is much smaller than the module base.
This is the institutional tension at the heart of the issue. A manufacturing policy can create demand for local production, but the production chain still needs sufficient capacity, compatible technology and functioning facilities. If module capacity expands faster than cell capacity, the constraint moves upstream. If the approved domestic supply is not available in adequate volume, project execution and manufacturer planning can come under pressure. Shah’s call for a 12-month extension is an industry position, not an announced government decision, and the source material does not indicate whether the government has accepted it.
The numbers also show why capacity announcements need to be read cautiously. Solex’s own Indian plans include a rise from 4 GW of module capacity to 10 GW, alongside 10 GW of cell manufacturing and 2 GW of ingot and wafer production. These are substantial planned capacities, but the report does not provide commissioning dates, financing details, plant locations beyond the existing Gujarat operation, or expected production levels. The same caution applies to the proposed US projects, for which the company has not disclosed locations or investment allocations.
The distinction between modules, cells and upstream materials is especially important for urban and infrastructure planning. Solar generation is ultimately deployed through buildings, industrial facilities, open land and electricity networks. But the equipment that enables that deployment is produced through industrial systems requiring land, power, logistics, skilled labour, capital and regulatory clearances. A shortage at any stage can affect how quickly renewable-energy projects move from procurement to construction and commissioning.
The source does not provide project-level evidence linking the reported manufacturing gap to delays in a specific solar park, rooftop programme or urban electricity project. It would therefore be premature to claim a direct impact on consumer tariffs, construction schedules or city-level power reliability. What the evidence does establish is a supply-chain imbalance identified by a company operating in the sector, combined with a policy framework that places greater emphasis on approved domestic sourcing.
Solex’s international ambitions also reveal the changing scale of India’s solar manufacturing industry. The company is not presenting the US as a substitute for its Indian expansion. Its roadmap includes larger domestic module and cell capacity as well as upstream production, while the US is being examined as an additional market. That suggests a strategy built around geographical diversification and deeper integration of manufacturing stages, although the company has not disclosed how the $1.5 billion would be divided between India and the US.
The next stage will determine whether these plans become operating assets. For the US proposal, the company has formed a team to assess investment requirements, locations and related parameters. For India, the outstanding questions concern the pace at which planned cell, ingot and wafer facilities become operational, the extent to which existing module capacity is usable, and how ALMM-II will be applied if cell availability remains constrained.
The evidence currently supports a clear conclusion but not a complete forecast. India has built a much larger reported module manufacturing base than cell manufacturing base, while older technology and non-operational capacity complicate the headline numbers. Solex Energy’s proposed US expansion responds to global demand and trade conditions, but it also underscores the need to evaluate solar manufacturing by operational capacity and supply-chain depth rather than by module announcements alone. The company’s next disclosures and any government decision on the ALMM-II timeline will clarify how the industry’s capacity gap is addressed.
