Adani Solar: Everything You Need to Know in 2026

Adani Solar is the brand that makes the most of its own panel. Most Indian manufacturers buy cells and assemble modules. Adani makes the ingots, the wafers, the cells and the modules at one site in Mundra, and that integration is where its pricing edge comes from.

It is also a younger name in rooftop solar than Tata or Waaree, which shows up in the service network rather than the product. This guide covers what Adani Solar actually sells in 2026, what it costs against the other two, how the warranty reads, and the one check that matters more than the brand.

Key takeaways

• Adani Solar is India's largest vertically integrated PV manufacturer, with 4 GW of cell and module capacity and 2 GW of ingot and wafer capacity at Mundra, Gujarat, and a stated plan to reach 10 GW by 2027.
• The ELAN Shine Gen-II TOPCon range runs 550 to 580 W at up to 22.5 percent efficiency, with bifacial modules up to 660 W.
• Warranty on the TOPCon range is 12 years product and 30 years performance, filed through Adani's own online portal.
• On Mono PERC it holds a steady ₹1 a watt advantage over Tata Power Solar; on TOPCon the gap closes because both buy N-type wafers on similar terms.
• ALMM List-I listed with DCR TOPCon models, so it qualifies for PM Surya Ghar, subject to the model number on your bill of materials.
• It has shipped more than 20 GW of modules since inception, in India and to the United States.

Who Adani Solar is

Adani Solar is the solar manufacturing arm of the Adani Group, operating as Mundra Solar PV. The company describes itself as India's first and largest vertically integrated solar PV manufacturer, with 4 GW of cell and module capacity and 2 GW of ingot and wafer capacity, all at Mundra in Gujarat. The group has said it plans to build 10 GW of integrated solar manufacturing by 2027.

Since inception it has shipped over 20 GW of modules. Distribution is strongest in the west and north, in Gujarat and Rajasthan particularly, with residential PM Surya Ghar installations and utility projects both drawing on the same product line.

Adani Solar panel range in 2026

The catalogue covers the three technologies that dominate Indian rooftops and plants.

• Mono PERC - Technology: P-type PERC, Wattage: Mid-400 W band, Module efficiency: Around 20 to 21 percent, Typical fit: Residential, budget commercial
• ELAN Shine Gen-II - Technology: N-type TOPCon, Wattage: 550 to 580 W, Module efficiency: Up to 22.5 percent, Typical fit: Residential premium, commercial
• Bifacial - Technology: N-type bifacial, dual glass, Wattage: Up to 660 W, Module efficiency: Higher, site dependent, Typical fit: Ground mount, carports, large C&I

The bifacial 660 W bracket is one place Adani stands out: Tata does not offer a comparable module in that class, so for an open-ground array or a carport the comparison is Adani against Waaree rather than against Tata.

For the choice between the PERC and TOPCon rows, our TOPCon vs Mono PERC guide sets out when the newer cell pays for itself and when it does not.

Warranty

On the ELAN TOPCon range Adani offers a 12-year product warranty and a 30-year linear performance warranty. Claims are filed online through Adani Solar's own portal, and authorised channel partners can register and file directly with the Mundra service desk rather than through a dealer chain.

That last point is worth asking your installer about. An authorised channel partner shortens the claim path. A dealer three steps removed from the manufacturer does not. Solar panel warranty claim in India covers what to keep from commissioning day so that the claim, when it comes, is about the module and not about the paperwork.

Adani Solar panel price in India in 2026

Adani's integration shows up as a consistent ₹1 a watt advantage over Tata Power Solar on Mono PERC. On TOPCon the gap largely disappears, because both companies buy N-type wafers on similar terms and the cell process is the cost driver.

In practical terms, that puts Adani close to Waaree and slightly under Tata across most of the range. Modules are roughly 45 to 50 percent of a rooftop project's cost, so on a small residential system in Tamil Nadu the installed figure lands in the usual ₹58 to ₹70 per watt band before subsidy, with Adani modules sitting toward the lower half of it.

Brand premium is only visible when every quotation is converted to a rate per watt. Is your solar quote too high walks through that conversion.

ALMM, DCR and the PM Surya Ghar subsidy

Adani Solar is on MNRE's ALMM List-I and lists DCR-compliant TOPCon modules, which is what the PM Surya Ghar subsidy requires.

The same warning applies as with every brand: ALMM status is model-specific. "Adani TOPCon" on a quotation is not enough. The bill of materials must carry the exact model number, and that number must be on the current list. Off-list models look identical on a brochure and fail the subsidy inspection after installation. Some installers quote a big brand on the cover sheet and a generic import on the BOM; the model number is the only thing that settles it.

Where Adani Solar is strong, and where to be careful

Strong on cost per watt at the PERC end, because the company makes its own wafers and cells. Nobody else in India controls that much of the chain at one site.

Strong on bifacial, with a 660 W dual-glass module that suits ground mounts and carports where Tata has no equivalent.

Be careful with service depth. Adani is the scaled new entrant. Tata is the legacy incumbent with decades of service partners. If the property is somewhere the Adani channel is thin, a warranty visit takes longer, and that is the single biggest difference between the two.

Be careful with the catalogue name. Ask which series and which model. The Mono PERC and the ELAN TOPCon are different products at different prices with different warranties.

Adani Solar vs the alternatives

Against Tata Power Solar, Adani is cheaper on PERC, comparable on TOPCon, and stronger on bifacial. Tata's edge is its own EPC arm and the depth of its physical service network. See Tata Power Solar: everything you need to know in 2026.

Against Waaree, the two are Gujarat neighbours at similar prices. Waaree has far more capacity and a wider catalogue, especially at the HJT top end. Adani's integration is deeper. See Waaree Solar: everything you need to know in 2026.

Against Premier Energies, Premier makes its own cells too and lists a 12/30 warranty on its TOPCon, at a Hyderabad plant closer to the south. See Premier Energies: everything you need to know in 2026.

Buying Adani Solar in Tamil Nadu

Adani's manufacturing is in Gujarat and its distribution is strongest in the west and north. In Tamil Nadu, availability is through distributors and channel partners, and the practical question to ask an installer is whether they are an authorised Adani channel partner or buying through a dealer. The answer determines who you call in year eight.

Everything else is the standard checklist: model number on the BOM, ALMM check done, serial numbers photographed at commissioning, and a structure designed for the coastal wind load. How to verify a solar company covers the rest.
