Did you know India added a record 45 GW of solar capacity in a single year, FY 2025-26, pushing the country past 100 GW total installed solar and making it the third-largest solar market in the world, right behind China and the US? And here’s the wild part, most of the panels going into all that new capacity are now actually made in India, thanks to a 40% import duty on Chinese modules that basically forced the entire industry to scale up domestic manufacturing almost overnight. So if you’re curious who’s actually building all these panels, here’s our rundown of the top 10 solar panel companies in India 2026.
1. Waaree Energies
There’s really no contest for the top spot here. Waaree is India’s largest solar panel manufacturer by a wide margin, with capacity estimates ranging from around 12 GW to as high as 18.7 GW depending on which facility count you’re looking at, and they’re reportedly pushing toward 25 GW by mid-2026. Founded way back in 1989 and headquartered in Mumbai, Waaree exports to more than 65 countries and has built one of the widest dealer networks in the country, which basically means if you’re a DISCOM-empanelled installer anywhere in India, chances are you’ve got Waaree panels in stock. They’ve also moved fast into advanced N-type TOPCon cell technology, which is honestly where the whole industry is heading right now.
2. Adani Solar
Adani Solar is the Adani Group’s solar manufacturing arm, and true to Adani form, they went big, building one of India’s first fully vertically integrated manufacturing setups at the Mundra Electronics Manufacturing Cluster in Gujarat. Founded in 2016, they’re currently running around 4 GW of cell capacity, and that vertical integration thing actually matters a lot here, it means better quality control and more reliable supply since they’re not depending on outside vendors for key components. Slightly pricier than some competitors, but the brand backing makes warranty claims genuinely easier, which counts for a lot over a 25-year panel lifespan.
3. Tata Power Solar
If you want the “old reliable” of Indian solar, this is it. Tata Power Solar has been around for over three decades, making it one of the oldest names in the entire industry, and that legacy really shows in their service network and reputation specifically in the residential and rooftop segment. They’re not chasing the absolute biggest capacity numbers the way Waaree or Adani are, but for homeowners specifically who want a name they can trust with decades of accountability behind it, Tata’s usually the first one that comes up.
4. Vikram Solar
Kolkata-based Vikram Solar has been in the game since 2006 and has built a genuinely strong global reputation, supplying modules to large solar parks both in India and internationally. They’re currently ALMM-listed at around 2.6 GW capacity and have leaned hard into high-efficiency module technology as their main differentiator rather than trying to out-scale the bigger players. Honestly, for ground-mount and utility-scale projects specifically, Vikram gets specified a lot.
5. Premier Energies
Premier Energies has quietly become one of the names EPC developers actually look for when they need large-scale module supply, currently sitting around 2.5 GW of ALMM-listed capacity. They’re grouped consistently alongside Waaree, Adani, and Vikram as one of the go-to manufacturers for utility-scale developers specifically, which says a lot given how competitive that segment has gotten.
6. RenewSys
Here’s something genuinely interesting about RenewSys, they’re one of the very few Indian manufacturers that doesn’t just make the panels themselves, they also produce key components like encapsulants and backsheet materials that go into the panels. That’s a pretty rare level of vertical integration for the industry, and it gives them a genuine edge in quality consistency since they’re not relying on third-party suppliers for the materials sandwiched inside every module.
7. Goldi Solar
Goldi Solar has quietly built one of the largest capacities in the entire country, reportedly around 15.2 GW, putting it right up there with Waaree in raw manufacturing scale, even though it doesn’t always get the same headline attention. They’re increasingly named alongside the top utility-scale manufacturers whenever developers are comparing options for big projects.
8. EMMVEE
EMMVEE runs a current operational capacity of around 4.5 GW and has a presence in 39 countries, specialising specifically in high-efficiency MonoPERC, bifacial, and smart module technology. They’ve built a reputation on technical specialisation rather than pure scale, which has made them a genuine go-to for projects specifically needing more advanced panel tech.
9. Saatvik Green Energy
Saatvik has positioned itself specifically around advanced N-Type TOPCon bifacial technology, the kind of thing that’s becoming the new standard across the industry, and it’s consistently named as a strong choice for developers prioritising newer panel tech over pure capacity numbers. It’s a genuinely fast-rising name in recent industry rankings.
10. Loom Solar
Rounding out the list, Loom Solar has carved out its own space particularly in the residential and rooftop segment, appearing consistently in top-10 lists alongside the much bigger utility-scale players. It’s proof that you don’t need Waaree or Adani-level capacity to earn a spot among India’s most recognised solar brands, especially if you know exactly which customer segment you’re serving.
Frequently Asked Questions
Q1. Which company makes the most solar panels in India right now?
A: Waaree Energies is India’s largest solar panel manufacturer, with capacity estimates ranging from 12 GW up to nearly 18.7 GW depending on the specific facility count, and they’re targeting over 25 GW by mid-2026.
Q2. Why did Indian solar manufacturing suddenly grow so fast?
A: The government imposed a 40% Basic Customs Duty on imported solar modules back in April 2022, which basically pushed companies like Waaree, Adani, Tata Power, and Vikram to massively scale up domestic manufacturing. India’s domestic capacity now exceeds 60 GW annually.
Q3. What does ALMM-listed actually mean, and why does it matter?
A: ALMM stands for Approved List of Models and Manufacturers, it’s basically MNRE’s official list confirming a manufacturer’s modules qualify for projects receiving central financial assistance. If you’re doing a project under schemes like PM Surya Ghar, only ALMM-listed panels are eligible.
Q4. Is Adani Solar or Waaree better for a home rooftop installation?
A: Waaree generally has the wider dealer network and more competitive pricing, making it a common pick for residential installers, while Adani offers excellent quality and vertical integration but usually at a slightly higher price point. Tata Power Solar is also a strong pick specifically for rooftop projects given its decades-long service reputation.
Q5. What’s the newest panel technology these companies are shifting toward?
A: Most major manufacturers, including Waaree, Adani, Saatvik, and EMMVEE, have been rapidly shifting to advanced N-type TOPCon cells and bifacial module designs, which offer better efficiency than the older Mono PERC technology that dominated the market just a couple of years ago.
