Investment Rationale:
🧨Strong Demand for Renewable Energy:
The global energy landscape is shifting dramatically, fueled by climate action goals, energy security concerns, and ESG mandates. With India targeting 500 GW of non-fossil fuel capacity by 2030, solar is at the forefront of this transformation.
It’s specialization in utility-scale projects aligns well with this demand. Supportive policy initiatives (e.g., ALMM waiver extension, green energy corridor investments, PLI schemes) further strengthen its long-term prospects.
(IEA, 2024; MNRE, 2025)
🧨Robust Project Pipeline & Execution Track Record:
- ₹10,500 crore unexecuted order book ensures strong revenue visibility for FY26 and FY27.
- Active bid pipeline of 23 GW in India
- Secured 11 out of 12 private-sector IPP projects in H1 FY25.
- Emerged as L1 bidder for 225 MW solar PV project in Gujarat.
- Consistently executing international projects in Saudi Arabia, Oman, and Australia.
This reflects SW Solar’s execution capability, pricing competitiveness, and strong pre-qualification credentials.

Reliance’s 32.5% stake gives SW Solar Ltd:
- Access to financial muscle and potential integration into a larger green energy ecosystem.
- Entry into next-gen solar storage, hydrogen, and grid infra segments via synergy.

Valuation & Upside Potential:
- Current Market Cap: ₹7,282.69 crore (as of July 3, 2025).
- P/E Ratio: ~89.41 (trailing; due to base-effect from prior year losses).
- P/B Ratio: ~7.63.
- 52-week Range: ₹218.45 – ₹828.00.
- Intrinsic Value Estimate: ₹399.44.
- Upside Potential: ~21% from current price of ₹329.
Some platforms suggest the stock is undervalued by ~33% based on future cash flow models. While the high P/E appears stretched, it reflects earnings normalization from a low base.
