India’s solar manufacturing industry is expanding as domestic companies increase solar module production and invest in solar cells.
India’s solar manufacturers are expanding as companies increase production of photovoltaic (PV) modules and invest in solar cells and other stages of the supply chain. Government measures, including the Production-Linked Incentive (PLI) scheme and the Approved List of Models and Manufacturers (ALMM) framework, form part of the policy backdrop for domestic production.
The solar manufacturing industry is pursuing different strategies. Some are strengthening their position through large-scale module production, while others are expanding into solar cells and planning deeper integration across the manufacturing value chain.
The following selection considers manufacturing scale, reported capacity, expansion momentum and the potential to strengthen domestic solar production. Capacity figures are drawn from company disclosures and other published sources available for this review. They are not all directly comparable: installed or commissioned capacity, nameplate capacity, production volumes and planned projects are different measures. Announced expansion should not be treated as operational capacity.
Waaree Energies
Waaree Energies is among India’s largest solar PV manufacturers, with a substantial manufacturing footprint in India and the United States. Its scale, production performance and plans to expand solar-cell manufacturing place it at the top of this editorial selection.
In its Q1 FY2026–27 update, Waaree reported global solar PV module manufacturing capacity of 25.8 GW and solar-cell capacity of 5.4 GW. The company also reported module production of 3.24 GW during the quarter, up 41.51 per cent year on year.
Waaree is also pursuing backward integration. Its 10 GW solar-cell facility at Unn, Gujarat, is progressing and is expected to begin production during FY2026–27. If implemented as planned, the project will strengthen the company’s position beyond module manufacturing.

Vikram Solar
Vikram Solar has significantly expanded its solar-module manufacturing footprint, with facilities in West Bengal and Tamil Nadu. Its recent capacity additions and plans to develop an integrated manufacturing ecosystem make it one of the prominent companies to watch in India’s solar industry.
The company’s 6 GW manufacturing facility at Gangaikondan, Tamil Nadu, was inaugurated in August 2026. Along with its Vallam facility, the expansion has taken Vikram Solar’s reported commissioned module manufacturing capacity to 15.5 GW.
Vikram Solar is also pursuing backward integration into solar cells. Its manufacturing roadmap includes a 9 GW solar-cell facility targeted for FY2026–27. This is a planned capacity milestone and should not be confused with currently commissioned module capacity.

Goldi Solar
Goldi Solar has emerged as a significant participant in India’s expanding solar-module manufacturing sector. Its reported increase in module capacity and manufacturing footprint in Gujarat give it a strong place among the country’s fast-growing producers.
According to the company, its annual solar PV module manufacturing capacity has increased from 3 GW to 15.2 GW over 14 months. Its manufacturing locations include Pipodara, Navsari, Kosamba and Nana Borsora in Gujarat.
The company is also associated with solar-cell manufacturing expansion. However, the date and operational status of the 1.2 GW solar-cell line at Nana Borsora, cited in the supplied draft, should be confirmed through a dated company announcement before publication.
Goldi Solar’s reported module capacity places it among the larger manufacturers in this selection. Its longer-term standing will also depend on how effectively it brings additional manufacturing capacity into operation and expands into other stages of the supply chain.
At a glance
- Major locations: Gujarat
- Main product: Solar PV modules
- Company-stated module capacity: 15.2 GW
- Cell manufacturing: A 1.2 GW line is cited in the draft; commissioning status requires confirmation
- Future focus: Continued manufacturing expansion and greater integration
GREW Solar earns the fourth position in this selection on the strength of its reported module-manufacturing scale, ambitious expansion plans and proposed move into solar-cell production. Although its current reported module capacity is below that of some manufacturers placed earlier in the list, its growth trajectory makes it a noteworthy emerging player.
GREW Solar operates a solar PV module manufacturing facility at Dudu, near Jaipur, Rajasthan. The supplied draft puts its current module manufacturing capacity at 6.5 GW, with expansion targeted to take it to 11 GW.
The company is also developing a solar-cell manufacturing facility at Narmadapuram, Madhya Pradesh. The project has an initial planned capacity of 3 GW, with a longer-term target of 8 GW. The supplied draft further states that GREW applied in June 2026 for inclusion in ALMM List-II for 3.5 GW of N-Type TOPCon G12R cell manufacturing capacity.
The application should not be presented as an approval or as proof that the cell capacity is already operational. GREW is also pursuing deeper backward integration, including plans for ingot and wafer manufacturing in Madhya Pradesh. If these projects progress as intended, they could strengthen its presence across more stages of the solar PV manufacturing value chain.

Premier Energies
Premier Energies is a major Indian manufacturer of solar cells and modules, with manufacturing operations in Telangana and Andhra Pradesh. Its sizeable module capacity and expansion into advanced solar-cell manufacturing give it an important position in India’s domestic solar supply chain.
The company has reported annual module manufacturing capacity of 11.1 GW. Its expansion programme includes a 7 GW N-type TOPCon solar-cell facility at Naidupeta, Andhra Pradesh. Public reporting has described commissioning and trial runs, making it important to distinguish the plant’s commissioning and stabilisation status from its ultimate rated capacity.
There is a discrepancy between public disclosures on Premier Energies’ operational cell capacity. The company’s current corporate overview refers to 10.6 GW, while a CRISIL Ratings report published in August 2026 described 3.6 GW of cell capacity as of July 2026 and identified the commissioning and stabilisation of the new facility as an important factor. The latest company filing should be checked before a single operational figure is published.

Adani Solar / Mundra Solar PV
Adani Solar’s manufacturing operations are centred in Mundra, Gujarat, where the group is developing an integrated solar manufacturing ecosystem. Its presence in solar cells and modules, combined with further expansion plans, makes it a relevant participant in India’s efforts to strengthen domestic solar production.
In June 2026, Adani New Industries commissioned a 1.7 GW module production line, taking Adani Solar’s reported module-line capacity to 5.7 GW. The expansion was reported as part of Adani Enterprises’ Q1 FY2026–27 business update.
The Mundra manufacturing ecosystem spans solar PV modules and cells, while further integrated manufacturing development forms part of the group’s plans. The reported 5.7 GW figure refers to module-line capacity; it should not be interpreted as actual production or as a measure of capacity across every stage of the manufacturing chain.
