That is precisely why we’re here with this list of the Top 10 Major Solar Panel Companies In India 2025. Alright, let’s just get to it right away.
1. Waaree Energies Ltd.
Top-notch company in India for the manufacturing of solar panels is WAREE Energies, and we aren’t the only ones saying that. In the year 2025, the production rate is an enormous 13.3 GW of solar panels per annum. That is massive! Their solar panels have diverse applications ranging from rooftop installations to giant solar installations. Also, their products are exported to more than 68 countries. Recently, Waaree launched its cutting-edge N-Type TopCon bifacial modules scoring an output/rating of 585Wp, and has already supplied over 770MW of these to major clients like Aditya Birla and Engie India.
2. Tata Power Solar Systems Ltd.
With the establishment of 1989, Tata Power Solar is associated with trust and reliability in the industry. By 2025, they will produce a firm 4.3 GW of solar modules with the construction of a large new plant in the south of the country, Tamil Nadu. They are also getting their fingers into solar cell manufacturing, while projects in renewable energy grow. Tata Power has installed more than 1.5 lakh rooftop solar systems all over the country, and the company is now supporting the “Ghar Ghar Solar” campaign under PM Surya Ghar Yojana to solarize 10 lakh homes.
3. Adani Solar
Adani Solar runs really super advanced manufacturing operations, providing all services from ingot making to finished solar panels, through a fully integrated plant setup. This is a 4000 MW capacity envisaged for 2025, and the 10,000 MW target for 2026 is really ambitious. Every year, for the last six years, the Adani solar modules have been rated the best in the world by PV Evolution Labs (PVEL) for reliability. That said, there is an assured 30 GW solar park being developed by Adani Green Energy, out of the same parent group, in the Khavda and adjoining areas of Gujarat, with 1 GW already commissioned by 2025.
4. Vikram Solar
Vikram Solar can be another big one with a 3.5 GW manufacturing capacity and growing fast. With plants in West Bengal and Tamil Nadu, it manufactures tops in TOPCon and HJT technology panels. By 2025, they had secured a 1 GW order from JSW Neo Energy and are delivering about 400 MW for a solar project in Gujarat. Their Somera and Paradea panels are super durable when implemented for large-scale applications.
5. Saatvik Green Energy
Saatvik Green Energy might be newer, yet it’s a big player with a 3.8 GW capacity until 2025. The prospects of it doubling soon are very exciting. Their N-Type TOPCon panels are developing clout for superior performance and efficiency. A supply agreement was struck with the Haryana plant for 1 GW of panels, with the inception of a 3 GW solar cell plant to be finalized by end-2025. They have also bagged projects in Maharashtra and Himachal Pradesh to supply just over 200 MW.
6. Goldi Solar
What Goldi Solar has been able to achieve in just over ten years is really mind-boggling in our opinion. At the end of the year 2025, the company is rated at having 3 GW capacity with plans to reach 6 GW. Future-ready, cool AI-powered technology is installed in the panel assembly at the factory in Gujarat. Roofs and utility projects love to install Goldi’s HELOC Pro series up to 710 Wp, in bifacial as well as monofacial options. It exports to around 20 countries and is setting up a 5 GW solar cell plant to make imports kinda super convenient.
7. RenewSys India
RenewSys India gets the highest rating for its in-house manufacturing. It does everything in-house, from making panels and PV cells to encapsulants and backsheets. It has a 2.75 GW module capacity for 2025, and its DESERV SGALACTIC and EXTREME panels, with outputs between 430 and 590 Wp, are made to withstand even rough weather. The company exports to more than 40 countries, with recent government support for the expansion of its factories in Telangana.
8. Rayzon Solar
With an impressive 6 GW capacity, Rayzon Solar is making all the noise, being a relative newcomer. The company is situated in Surat and focuses on designing high-efficiency solar panels to cater to both the Indian market and abroad. Industrial and commercial solar power generation projects make use of their panels while paying strong attention to sustainability. Rayzon happens to be a subsidiary of the Enpee Group, which further supports Rayzon’s development.
9. Premier Energies
This one, oh, it technically is a big name with 3.36 GW capacity in 2025. They supply mono PERC and TOPCon bifacial panels capable of the upper range of 670 Wp. They maintained a 1 GW plant near-land in Telangana, which will start this year, as well as have an order of 608 MW for the NTPC Rajasthan solar project. Premier Energies considers moving out of the territory: maybe, even a manufacturing facility in the US, depending on their international plans.
10. Loom Solar
Loom Solar has its unique things, and that very uniqueness defines them. With a smaller 100 MW capacity, their impacts are massive, especially in the rural and semi-urban zones. They sell mono PERC panels, lithium batteries, and inverters straight to houses by way of an extensive network of resellers in over half a thousand districts. Thanks to this super precise focus on a digital-first model and very easy-to-install rooftop kits, Loom Solar is a huge favorite amongst homeowners and small businesses.
