India has officially overtaken the United States and the European Union to become the world’s second-largest solar market by annual installations. Adding a record-breaking 44.6 GW of solar capacity in the last fiscal year alone, the nation’s journey toward its 500 GW non-fossil fuel target by 2030 is moving at an unprecedented pace.
This “Green Gold Rush” is being driven by aggressive government schemes like PM Surya Ghar (Rooftop Solar) and PM KUSUM 2.0, alongside a massive shift toward domestic manufacturing fueled by the Production-Linked Incentive (PLI) scheme.
Here are the top 10 solar companies in India currently dominating the landscape through innovation, manufacturing scale, and massive EPC (Engineering, Procurement, and Construction) projects.
1. Adani Solar
A titan in the industry, Adani Solar remains India’s most vertically integrated player. Spanning the entire value chain—from ingots and wafers to cells and modules—they operate a massive 4 GW facility in Mundra, Gujarat, with plans to hit 10 GW by the end of this year. Their focus on N-Type TOPCon technology has made them a preferred choice for large-scale utility projects.
2. Tata Power Solar
With over three decades of experience, Tata Power Solar is the gold standard for reliability. They hold a massive share of the residential rooftop market and have executed some of India’s most complex projects, including the country’s largest floating solar plant. Their end-to-end service model makes them a household name for quality and after-sales support.
3. Waaree Energies
Headquartered in Mumbai, Waaree is currently India’s largest solar module manufacturer by capacity. In 2026, they have expanded their focus toward specialized solutions like BIPV (Building-Integrated Photovoltaics) and flexible solar panels, catering to modern architectural needs and the growing electric vehicle (EV) charging infrastructure.
4. Servotech Renewable Power Systems
Emerging as a dominant force in 2026, Servotech has bridged the gap between high-end technology and affordability. Following their strategic acquisition of Rhine Solar, they have integrated advanced production lines to manufacture high-efficiency panels that perform exceptionally well in the varied Indian climate.
5. Vikram Solar
Kolkata-based Vikram Solar is a global heavyweight, exporting high-efficiency modules to over 30 countries. Their Somera and PreXos series are known for high-wattage output, and they recently secured massive contracts for 1 GW supply chains, cementing their status as a tier-1 global manufacturer.
6. Sterling & Wilson Renewable Energy
When it comes to Solar EPC on a global scale, Sterling & Wilson is unmatched. They recently made headlines by winning a ₹34.90 billion contract from Coal India for an 875 MW project in Rajasthan. Their expertise in large-scale project management and O&M (Operations & Maintenance) keeps them at the top of the utility-scale sector.
7. Goldi Solar
Based in Surat, Goldi Solar is one of the fastest-growing brands in the country. They have made a massive jump in manufacturing capacity, aiming for 14 GW by the end of this fiscal year. Their focus on “Quality That Outlasts” has made them a favorite in coastal regions where panels face high humidity and salt mist.
8. Premier Energies
Operating out of a state-of-the-art facility in Hyderabad, Premier Energies focuses on high-wattage modules (600W+). They are a key player in the commercial and industrial (C&I) segment, helping shopping malls and large factories offset massive energy bills with high-efficiency cell technology.
9. ReNew (formerly ReNew Power)
ReNew is a leader in the “Clean Energy as a Service” model. Beyond just manufacturing, they are a major Independent Power Producer (IPP). In 2026, they are leading the charge in hybrid projects—combining solar, wind, and battery storage to provide 24/7 round-the-clock (RTC) renewable power to the national grid.
10. Loom Solar
Specifically targeting the residential segment, Loom Solar has revolutionized the market with a “digital-first” approach. Their plug-and-play solar solutions and sleeker, all-black panels appeal to urban homeowners who value aesthetics as much as efficiency.
The Road Ahead: 2026 and Beyond
The Indian solar industry is no longer just about importing and installing; it is about “Make in India.” With domestic module manufacturing capacity exceeding 120 GW, India is positioning itself as a global alternative to traditional supply chains. As technology shifts toward Bifacial modules and Green Hydrogen integration, these ten companies are the engines driving India’s energy independence.
