GREW Solar Private Limited (CIN: U40100GJ2022PTC130052) was incorporated on 11 March 2022 7 as a subsidiary of the Chiripal Group 2, a diversified manufacturing conglomerate established in 1972 3. In three years, it has positioned itself as India's youngest and fastest-growing solar PV module manufacturer 1. The company's primary revenue streams span module sales — anchored by a 3-stage backward integrated manufacturing model rare in the domestic industry 4 — and EPC services delivered through GREW Renewables, its specialised division offering ground mount, floating, and rooftop solar installations alongside asset management 5. Manufacturing operations are concentrated domestically, with Phase 1 (1.29 GW) and Phase 2 (1.62 GW) facilities in Dudu, Rajasthan, and additional capacity under expansion in Madhya Pradesh 6. The integrated production footprint underpins GREW Solar's cost and supply-chain thesis as India accelerates its renewable energy build-out.

GREW Solar (GEPL) delivered exceptional revenue growth from INR 1.99 billion in FY24 to INR 14.09 billion in FY25 1, driven by volume expansion from 143 MW to 1,050 MW 9. EBITDA margin improved to 14% in FY25 from 11% in FY24 4, with absolute EBITDA rising from INR 0.22 billion to INR 1.92 billion 3. Gross interest coverage strengthened to 2.72x from 1.47x 5, while net leverage compressed sharply from 23.06x to 2.95x 7, reflecting the company's rapid transition from a capital-deployment phase to an earnings-generating entity. India Ratings upgraded the long-term rating from IND BBB-/Stable to IND BBB+/Stable between July 2023 and June 2025 10, validating the improving credit profile. Early 1Q FY26 momentum — INR 5.99 billion in revenue and INR 1.02 billion in EBITDA on 431 MW of sales 2 — points to continued operating leverage as capacity scales.

GREW Solar's leadership combines Chiripal Group institutional depth with renewable sector expertise. CEO Vinay Thadani, a founding director since 11 March 2022 7, previously held CFO and COO roles at Vishal Fabrics Limited before joining the Chiripal Group in 2017 1, and has positioned the company toward 8 GW production capacity 3; his stated priorities for the ₹1,050 crore raise center on expansion, operational efficiency, and technology scale-up 9. Managing Director Sankar Ray brings 26 years of renewable energy operations experience 4. Ownership is concentrated — Chiripal Renewable Energy Private Limited holds 54.36% and Chiripal Industries 6.17% 8 — making board independence a governance watch-point for incoming PE capital.

GREW Solar presents a compelling growth-stage PE opportunity, combining rapid manufacturing scale-up with strong institutional demand visibility and structural policy tailwinds in India's solar sector. Three value drivers underpin the thesis.

Scale & Technology Leadership. By 2025, GREW Solar scaled its operational capacity to 3 GW, producing high-efficiency M10 TOPCon modules of up to 590 Wp 1. Its ALMM-listed module capacity stood at 2,803 MW as of June 2025, a critical regulatory prerequisite for winning government-procured solar tenders 8.

Policy-Backed Competitive Moat. GREW Solar won 2 GW wafer-to-module capacity under India's PLI scheme, with a $69.3 million allocation 5. India Ratings affirms the favourable domestic demand outlook for module and cell manufacturers, subsidy support, and Chiripal Group parentage as key rating strengths 7.

Revenue Visibility & Near-Term Catalysts. The order book of 1.83 GW at end-June 2025 translates to INR 25.17 billion in revenue visibility over the next 10–12 months 4. A ₹2,000+ crore NTPC REL order for 1,464.5 MW of modules across Uttar Pradesh 2 3 and a ₹1,050 crore funding round to expand solar cell capacity from 3 GW to 8 GW 6 represent the most immediate earnings and strategic catalysts.

GREW Solar's risk profile is dominated by execution and leverage exposure from its aggressive capacity buildout, with secondary concentration risks across customer and geography.

Execution & Leverage Risk (High Probability, High Impact): Phase 4 (3.5 GW modules, Dudu) and Phase 5 (3 GW cells, Narmadapuram) carry a combined capex of INR 27.52 billion 4, driving gross leverage that Ind-Ra expects to remain elevated near-to-medium term — FY25 at 3.91x versus FY24 at 17.06x 2. Loan covenants impose tight maintenance tests including a long-term debt/EBITDA ceiling of 2.75x and DSCR of 1.89x 7; any commissioning delay or demand shortfall could trigger breaches.

Input Cost & Forex Risk (Moderate Probability, Moderate Impact): GREW Solar imports its key raw material, and with hedging limits of only INR 0.086 billion, adverse forex movements pose a direct margin threat 3. Technological obsolescence adds a structural dimension, requiring continuous product upgrades 1.

Policy Reversal Risk (Low Probability, High Impact): Current protection — 40% duty on imported modules and 27.5% on cells effective April 2025 8 — underpins domestic pricing power. Any reduction would materially compress margins.

Concentration Risks: Geographic concentration is acute: existing Phase 1 (1.29 GW) and Phase 2 (1.62 GW) capacity is entirely in Dudu, Rajasthan 6, with Phase 4 expanding the same location. Customer concentration is illustrated by the single NTPC REL order exceeding ₹2,000 crore 5, representing a dominant revenue event risk.

Downside Scenario: A 6–12 month commissioning delay on Phase 4/5, combined with a 10–15% INR depreciation and partial policy duty rollback, would pressure EBITDA margins, risk covenant breaches on the long-term debt/EBITDA test 7, and eliminate the leverage reduction trajectory Ind-Ra currently projects 2.

GREW Solar's manufacturing lines have executed a rapid and sustained utilisation ramp, signalling strong operational discipline. Phase 1 capacity utilisation improved from 35% in FY24 to 73% in FY25, reaching 92% (annualised) in 1Q FY26 1. Phase 2 similarly accelerated from 41% in FY25 to 82% (annualised) in 1Q FY26 2. Ind-Ra projects operational-line utilisation to stabilise at 80%–85% through FY26 3. Throughput efficiency is underpinned by Phase 2's rated output of 160 modules per hour per line at a maximum wattage of 700 W 4. Product-level quality is reinforced by 100% String Level EL and Triple Stage PV Module EL Testing, with all modules carrying guaranteed positive tolerance 6 and a 30-year linear performance warranty 7. The step-change in volume — from 143 MW in FY24 to 1,050 MW in FY25 and 431 MW in 1Q FY26 alone 10 — validates that line ramp-up has translated directly into output, a critical confirmation ahead of the Phase 3 capacity addition.
