By Meghna Sharma India has moved from heavy dependence on imported solar equipment to one of the world’s fastest-growing photovoltaic manufacturing bases. The Ministry of New and Renewable Energy reported that domestic solar-module manufacturing capacity reached about 172 GW by March 31, 2026, compared with only 2.3 GW in 2014. The ₹24,000-crore Production Linked Incentive programme and the Approved List of Models and Manufacturers framework have accelerated investment in high-efficiency domestic production.
The industry is also becoming more integrated. Leading manufacturers are adding solar-cell, ingot, wafer, encapsulant and other component capacity rather than limiting themselves to panel assembly. Here are the Top 10 Solar Panel Manufacturing Companies in India in 2026, selected for current module scale, cell integration, technology, reliability, market reach and expansion plans.
1. Waaree Energies
Waaree Energies is India’s largest solar-module manufacturer. In 2026, company material placed its Indian module capacity above 20 GW, alongside 5.4 GW of cell manufacturing. It produced a record 12.6 GW of modules in FY2025-26 and reported ₹26,536.77 crore in revenue from operations. Waaree manufactures TOPCon, HJT and bifacial modules and is building a 10 GW ingot-and-wafer facility, giving it the strongest combination of scale and backward integration.
2. Vikram Solar
Vikram Solar reached 15.5 GW of commissioned module manufacturing capacity by August 2026 after adding major plants at Vallam and Gangaikondan in Tamil Nadu. Its factories also operate in West Bengal. The company has shifted toward N-type high-efficiency modules and is developing substantial solar-cell capacity at Gangaikondan. Its export experience, advanced automated plants and aggressive backward-integration programme make it one of India’s most important photovoltaic manufacturers.
3. Goldi Solar
Gujarat-based Goldi Solar reports about 15.2 GW of annual module manufacturing capacity across facilities including Pipodara, Navsari, Kosamba and Nana Borsara. Its modern lines manufacture TOPCon and Mono PERC modules with increasing use of automation and AI-assisted quality control. Goldi is also moving into cell manufacturing, beginning with a 1.2 GW line and planning much larger expansion. Its rapid capacity growth has transformed it into a major national manufacturer.
4. Premier Energies
Premier Energies is one of India’s deepest cell-to-module manufacturers. Its 2026 manufacturing platform is designed for around 11.1 GW of modules and 10.6 GW of solar cells. The Hyderabad-headquartered company produces Mono PERC and N-type TOPCon products, with reported TOPCon cell efficiencies up to 25.2%. New facilities in Andhra Pradesh and Telangana are expanding its scale further, making Premier particularly important as domestic-cell requirements become more significant.
5. Rayzon Solar
Rayzon Solar has grown from a small Gujarat manufacturer into an 11.3 GW module producer in FY2025-26. Its portfolio includes TOPCon, bifacial, monofacial and all-black modules for utility, commercial and residential projects. The company also exports to markets including the United States, Canada, Germany, South Africa and Kenya. Rapid expansion and strong domestic shipments have made Rayzon one of the fastest-rising manufacturers in India.
6. Emmvee
Bengaluru-based Emmvee combines more than three decades of solar experience with major current capacity. As of March 2026, it reported 10.3 GW of module manufacturing and 2.94 GW of solar-cell capacity across Karnataka facilities. Its automated production lines support high-efficiency products including N-type technologies. The combination of large-scale module production, in-house cells and an established export and utility-market presence gives Emmvee a strong position.
7. Adani Solar
Adani Solar stands out for vertical integration. Its Mundra manufacturing ecosystem covers ingots, wafers, cells, modules and several module components. Adani Enterprises reported module-line capacity of 5.7 GW after commissioning another 1.7 GW in June 2026, alongside 4 GW of cell capacity and 2 GW of ingot-and-wafer capacity. Its module scale is below the leaders, but its upstream integration makes it strategically important to India’s domestic solar supply chain.
8. RenewSys India
RenewSys is India’s first integrated manufacturer of solar PV modules and key components such as cells, encapsulants and backsheets. In March 2026, it opened a 3 GW automated module facility at Khopoli, increasing total module capacity to 5.6 GW. It is also expanding N-type TOPCon cell capacity and already manufactures large volumes of encapsulants and backsheets. This broader component base differentiates RenewSys from companies focused mainly on module assembly.
9. Tata Power Solar / TP Solar
Tata Power operates one of India’s strongest integrated solar factories through TP Solar. Its Tirunelveli plant has 4.3 GW each of solar-cell and module capacity, while the older Bengaluru facility adds further production. The combined manufacturing platform is about 4.9 GW. In FY2025-26, the Tirunelveli operation produced more than 3.8 GW of modules and 3.7 GW of cells, supported by strong rooftop, EPC and utility demand within the Tata Power ecosystem.
10. Saatvik Green Energy
Saatvik Green Energy’s Ambala facility operated at 4.8 GW of annual module capacity in FY2025-26 and produced a record 3,162 MW during the year. Its order book stood at about 5.89 GW at March-end. Saatvik is also developing an integrated Odisha manufacturing base with new module and solar-cell capacity and has announced expansion into encapsulants, inverters and eventually ingots and wafers. This makes it one of India’s fastest-growing solar manufacturers.
Why ALMM and Domestic Cell Manufacturing Matter in 2026
India’s solar market cannot be judged by module capacity alone. The ALMM framework determines which approved module models and manufacturers can be used in many government-supported and regulated project categories. ALMM List-II for solar cells has also strengthened the push toward locally manufactured cells rather than panels assembled entirely from imported cells.
That makes backward integration increasingly valuable. Manufacturers with their own cells can control more of the supply chain and are better placed for domestic-content requirements. The government has also announced that ALMM requirements will eventually extend upstream to ingots and wafers from June 2028.
Conclusion
India’s solar panel manufacturing industry in 2026 is far larger and more sophisticated than it was only a few years ago. Waaree leads on scale, while Vikram Solar and Goldi have built very large module platforms. Premier Energies stands out for cell integration, and Rayzon and Emmvee have also crossed the 10 GW mark.
Adani Solar, RenewSys and Tata Power bring deeper integrated-manufacturing capabilities, while Saatvik is expanding quickly across cells and other components. As policy moves further upstream from modules to cells, wafers and ingots, manufacturers combining scale, technology, reliability and domestic integration should gain the greatest strategic advantage.
FAQs
Q1. Does ALMM listing mean a solar panel is automatically the best quality?
No. ALMM establishes eligibility and manufacturer/model compliance for specified projects. Buyers should still compare efficiency, degradation, warranties, temperature performance, independent reliability testing and service support.
Q2. What is the difference between ALMM and DCR solar panels?
ALMM is an approved list of eligible manufacturers and models. DCR, or Domestic Content Requirement, requires specified components such as cells and modules to be made in India for schemes or tenders where DCR rules apply.
Q3. Why does solar-cell capacity matter if a company already makes modules?
A module manufacturer can assemble panels using purchased cells. In-house cell production gives a company greater supply-chain control, reduces dependence on imports and can help it qualify for projects requiring domestically manufactured cells.
Q4. Does a higher-wattage solar panel always mean better performance?
No. Higher wattage may reduce the number of panels needed, but long-term output also depends on efficiency, degradation, temperature coefficient, shading, installation quality and system design. Reliability over decades matters more than headline wattage alone.
Q5. What should buyers verify before choosing a solar panel manufacturer?
Check the exact module’s ALMM status when required, product and performance warranties, service support, certifications, independent reliability testing and whether the cells are domestic or imported when the project has DCR conditions.
