RenewSys: Everything You Need to Know in 2026

RenewSys is the Indian manufacturer that makes the parts other manufacturers buy. Its CONSERV encapsulants and PRESERV backsheets go into modules across the industry, and it builds its own panels on the same components. That matters because the encapsulant and backsheet are what keep moisture and ultraviolet light away from the cells for 25 years, and most module failures start there.

It is also the first Indian company to earn a 5-star Bureau of Energy Efficiency rating for a panel, and it holds a Kiwa PVEL Top Performer position in the 2026 reliability scorecard. This guide covers what RenewSys makes in 2026, how its warranty compares, where it sits on price, and who should be looking at it.

Key takeaways

• RenewSys is India's first integrated manufacturer of solar modules and their key components, founded in 2011, with a total installed module capacity of 5.6 GW.
• A new 3 GW automated module plant at Khopoli, Maharashtra was inaugurated in March 2026, alongside existing production in Hyderabad and Bengaluru.
• The N-type TOPCon bifacial range runs 585 to 635 Wp, and its TOPCon 650 Wp module is the first in India to earn a BEE 5-star rating.
• Warranty is 10 years product and 25 years performance, at the market norm rather than the 12/30 offered by the top tier.
• Kiwa PVEL Top Performer in the 2026 PV Module Reliability Scorecard, for a second consecutive year.
• ALMM List-I listed, exports to more than 40 countries, so PM Surya Ghar eligible subject to the model number.

Who RenewSys is

RenewSys India was founded in 2011 as part of the Enpee Group and describes itself as India's first integrated manufacturer of solar PV modules and their key components. That integration is unusual and specific: RenewSys manufactures encapsulants under the CONSERV name and backsheets under PRESERV, sells them to other module makers, and uses them in its own modules.

Its total installed module capacity is 5.6 GW. In March 2026 it inaugurated a 3 GW automated module manufacturing plant at Khopoli in Maharashtra, adding to production at Hyderabad and Bengaluru. It exports to more than 40 countries, and it has held Kiwa PVEL Top Performer status in consecutive PV Module Reliability Scorecards, an independent test programme that lenders and developers use to judge long-term module durability.

RenewSys panel range in 2026

RenewSys sells across Mono PERC and N-type TOPCon, in monofacial and bifacial dual-glass formats, with DCR options.

• Mono PERC - Technology: P-type PERC, anti-reflective coated glass, Wattage: Mainstream residential wattages, Typical fit: Homes, PM Surya Ghar
• TOPCon monofacial - Technology: N-type TOPCon, Wattage: Mid to high 500 W band, Typical fit: Residential premium, commercial
• TOPCon bifacial dual glass - Technology: N-type TOPCon, DCR options, Wattage: 585 to 635 Wp, Typical fit: Ground mount, C&I, DCR projects
• TOPCon 650 Wp - Technology: N-type TOPCon, BEE 5-star rated, Wattage: 650 Wp, Typical fit: Large C&I, utility

The BEE 5-star rating on the 650 Wp module is a first for an Indian panel. The Bureau of Energy Efficiency's star labelling runs from one to five, and five signals the module has surpassed the industry efficiency standard in the Bureau's testing. It is a consumer-facing label rather than a bankability one, but it is independent and it is Indian.

Warranty

RenewSys modules carry a 10-year product warranty and a 25-year limited performance warranty. That is the established Indian norm and it is a step below the 12-year product and 30-year performance cover that Waaree, Adani, Vikram and Premier now offer on their N-type ranges.

Two years of product cover is a real difference. It is also worth weighing against what RenewSys is actually good at, which is the durability of the encapsulant and backsheet that the product warranty exists to cover. A module built on components the maker controls, tested to Top Performer standard, is a module less likely to need that warranty. Both things are true; decide which matters more to you.

Whichever way you go, solar panel warranty claim in India covers the records that decide a claim.

RenewSys panel price in India in 2026

RenewSys does not publish a rate card. It is positioned as a cost-effective manufacturer, sitting below the premium brands and close to the value end of the ALMM-listed set.

Modules are roughly 45 to 50 percent of a rooftop project's cost, so a RenewSys system lands in the lower half of the ordinary ₹58 to ₹70 per watt installed band for a small Tamil Nadu residential system before subsidy. Convert every quotation to a per-watt rate before comparing; is your solar quote too high shows how.

ALMM, DCR and the PM Surya Ghar subsidy

RenewSys is on MNRE's ALMM List-I, and its TOPCon bifacial range includes DCR modules at 585 Wp and above. That is the combination PM Surya Ghar and net metering require.

Where RenewSys is strong, and where to be careful

Strong on the parts that fail. Encapsulant and backsheet are the module's weather seal. RenewSys makes both, sells both to the industry, and builds on both. Nobody else in India can say that.

Strong on independent testing. Kiwa PVEL Top Performer, twice running, and a BEE 5-star module.

Strong on the south. Hyderabad and Bengaluru production puts a plant within reach of Tamil Nadu.

Be careful with the warranty term. 10/25 is fine; 12/30 is better, and four competitors offer it.

Be careful with brand recognition. RenewSys is well known in the trade and little known to homeowners. If a familiar name matters to you, it will not provide one.

RenewSys vs the alternatives

Against Waaree, both are ALMM listed with 10 to 12 year product warranties and 25-year performance cover on comparable lines. Waaree is far larger and better distributed; RenewSys controls its own components. See Waaree Solar: everything you need to know in 2026.

Against Emmvee, the other big southern manufacturer, both offer 10-year product cover and both hold strong Kiwa PVEL records. Emmvee is roughly twice the size and makes its own cells. See Emmvee: everything you need to know in 2026.

Against Premier Energies, Premier offers 12/30 and makes its own cells in Hyderabad; RenewSys makes its own encapsulant and backsheet. Different integrations, similar geography. See Premier Energies: everything you need to know in 2026.

Buying RenewSys in Tamil Nadu

With production in Hyderabad and Bengaluru, RenewSys modules reach Chennai without crossing the country. Ask the installer which plant the stock comes from, insist on the model number, and record serial numbers at commissioning. How to verify a solar company covers the installer side.
