Everyone knows Rajasthan for its solar parks, Bhadla, the Thar Desert, and 325-plus sunny days a year. What gets less attention is what’s been building alongside all of that, a manufacturing base that didn’t really exist five years ago.
Rajasthan now holds around 10% of India’s total solar module manufacturing capacity, per Mercom India. Third nationally, behind Gujarat and Tamil Nadu. The companies responsible for that share aren’t fringe players, many are among the most seriously capitalised manufacturers in the country. Here are five with confirmed, operational facilities in the state.
1. GREW Solar
Location: Dudu, Jaipur District Module Manufacturing Capacity: 6.5 GW (expanding to 11 GW in 2026)
The 6.5 GW facility is expanding to 11.0 GW in 2026, and its modules are ALMM certified, a requirement for supplying government-backed solar projects in India. But capacity numbers alone don’t tell the full story. GREW Solar is one of only 11 companies in India to have received a PLI allocation for fully integrated solar manufacturing, not just modules, but the supply chain behind them.
That supply chain ambition is already taking shape. The 3.5 GW solar PV cell manufacturing facility in Narmadapuram, Madhya Pradesh is set to expand to 8.0 GW in 2026. It is the first step in a deliberate long-term backward integration strategy. Cells today, with further upstream integration to follow.
The company was named Solar Energy Manufacturer of the Year in 2025. Three years old, and already setting the pace.
2. INA Solar (Insolation Energy)
Location: Three facilities across Jaipur (including Sawarda, Delhi-Ajmer Expressway) Module Manufacturing Capacity: 5.5 GW combined
INA Solar started in 2015 with 80 MW of capacity. Today it runs three facilities in Jaipur with a combined 5.5 GW and plans on the table to reach 7.0 GW of modules and 4.5 GW of solar cells across Rajasthan and Madhya Pradesh.
The newest facility, at Sawarda on the Delhi-Ajmer Expressway, is worth singling out. 600,000 sq ft, AI and robotics-driven production lines, manufacturing M10R TOPCon modules with minimal manual intervention. It’s a different kind of facility to what India’s solar manufacturing sector looked like even three years ago.
INA Solar is BSE SME listed, ALMM listed, and its panels supply government programmes including PM-Kusum and PM Surya Ghar. One of Rajasthan’s most established manufacturing names.
3. ReNew Photovoltaics
Location: Mahindra World City, Jaipur Module Manufacturing Capacity: 3.55 GW
ReNew Photovoltaics is the manufacturing arm of ReNew Power, one of India’s largest renewable energy companies. Its Jaipur plant sits on 22 acres at Mahindra World City, producing around 15,000 modules a day. The March 2026 ALMM List-I update confirms 3.55 GW of enlisted capacity.
The reason for being in Rajasthan isn’t complicated. ReNew Power has a large project pipeline here. Manufacturing locally cuts procurement risk and logistics costs, and keeps the company competitive for government tenders that require ALMM-listed domestic supply.
It’s a model more developers are moving toward, own your generation, own part of your supply chain. For any solar panel company thinking about vertical integration, ReNew’s approach in Rajasthan is worth watching.
4. SAEL Industries
Location: Rajasthan Module Manufacturing Capacity: 3.2 GW TOPCon module assembly
SAEL is best known as a solar IPP with over 6.7 GW of solar assets across India, operational and under construction. Manufacturing came later, as a backward integration play. Rather than sourcing modules from the open market, the company built the capacity to supply its own projects.
The Rajasthan facility runs 3.2 GW of bifacial N-type TOPCon module assembly, with a 300 MW unit in Punjab alongside it. The technology choice reflects where utility-scale solar is heading, i.e., towards higher efficiency, better low-light performance, longer useful life.
SAEL has announced a larger integrated plant in Greater Noida, suggesting the Rajasthan operation is a step in a longer manufacturing build-out rather than a standalone move.
5. Acme Group (Acme Renewable Equipment Manufacturing)
Location: Jaipur Module Manufacturing Capacity: 1.2 GW
Acme Group invested roughly ₹230 crore to commission a 1.2 GW module manufacturing plant in Jaipur. It’s operational, ALMM listed, and employs over 700 people. The manufacturing entity, Acme Renewable Equipment Manufacturing, is a dedicated vertical within the group, not a side project.
The numbers Acme is targeting give a sense of intent. ₹10,000 crore in revenue from the manufacturing business by 2030. The Jaipur plant is the starting point for that ambition, with cell manufacturing capacity in the pipeline as the company moves toward backward integration.
At 1.2 GW, it’s the smallest facility on this list but Acme isn’t a small company and the trajectory here points firmly upwards.
The Bigger Picture
Gujarat still dominates around 45% of India’s module manufacturing capacity as of December 2025, per Mercom India. Rajasthan is not catching up to that overnight.
But the five companies here have a combined module capacity exceeding 17.5 GW, and most of them are actively expanding. More importantly, they chose Rajasthan for reasons that haven’t changed: land, sunlight, proximity to the country’s most active solar project market, and a state government that has made investment incentives a consistent part of its pitch.
The manufacturing story here is younger than the generation story. It’s also moving faster than most people realise.
