Solex Energy Ltd (NSE: SOLEX) is that Gujarati engineering student who went from building a science project solar cooker to running a ₹1,596 crore empire of glowing silicon wafers. At ₹1,477 per share, this solar daredevil has multiplied investor wealth 120% in five years — and it’s just warming up. H1 FY26 results sparkled brighter than a freshly washed solar panel: revenue hit ₹4,157 million (₹415.7 crore), up 51.6% year-on-year, while PAT powered ahead by 133.2% to ₹305 million. The company just switched on its 2.2 GW new module line in Gujarat and now claims a 4 GW commissioned capacity, with another 2.5 GW expansion on the way.
With an order book worth over ₹4,000 crore, a P/E of 30.4x, ROE at 38.7%, and debt-to-equity of 1.63x, Solex is the energetic, slightly over-caffeinated cousin of Adani Solar — efficient, ambitious, but still paying EMIs. The market clearly loves the wattage; in three months, it’s up 7.3%, and over six months, up nearly 20%. So, is this India’s next solar juggernaut or another overcharged inverter? Let’s plug in.
2. Introduction
There are two kinds of power in India — political and solar. Solex Energy seems to have mastered the latter. Born in 1995, long before “renewable” became a buzzword, the company has spent decades converting sunlight into cash flow. Headquartered in Surat, Gujarat, the land of diamonds, Solex now polishes photons instead.
In the last few years, the company’s journey has been electric — literally. From manufacturing small solar water heaters to becoming a full-stack solar module powerhouse with EPC (Engineering, Procurement & Construction) capabilities, Solex has gone from “light your home” to “light up the grid.” The FY25 order book stood at ₹175 crore — until 2025 turned into a blockbuster with back-to-back mega deals worth ₹451 crore and ₹544 crore.
The company now flaunts a 1.5 GW operational module capacity (soon 4 GW post-expansion) and aims to scale to 15 GW in the coming years. With marquee clients like Amul, ONGC, IIM Ahmedabad, and the Airport Authority of India, it’s not just a solar panel maker; it’s a national service provider for everything sunny and sustainable.
Still, it’s not all sunshine and subsidies. The stock trades at 8.85x its book value, hinting that optimism may be outpacing kilowatts. But with India’s renewable transition racing ahead and global supply chains tilting toward domestic manufacturing, Solex Energy might just have timed its sunrise perfectly.
3. Business Model – WTF Do They Even Do?
Solex Energy is in the business of harnessing the most dependable boss of all — the Sun. The company manufactures solar photovoltaic (PV) modules — the shiny blue panels you see on rooftops and industrial sheds — and executes EPC projects where it designs, procures, and constructs entire solar plants for clients.
It operates across three verticals:
Manufacturing: Produces Mono PERC and N-Type TOPCon modules ranging from 450 Wp to 750 Wp, with its new Tapi-R series (585–625 Wp, 23.14% efficiency) leading the charge.
EPC Solutions: Offers turnkey solutions for residential, commercial, and industrial installations.
OEM/ODM Services: Manufactures modules under other brands — think of it as the Foxconn of solar panels.
In plain terms: they design, build, and sometimes babysit your solar projects. Whether you’re a farmer needing water pumps or a bank wanting to go green without losing green, Solex will sell you a module, install it, and send you a quarterly report on how much Vitamin D your roof is absorbing.
And because every Indian promoter dreams big, Solex isn’t stopping there. The company plans to invest ₹1,500 crore to set up a 2 GW solar cell manufacturing line, making it vertically integrated — from wafer to watt. If it succeeds, Solex will control its supply chain like Ambani controls bandwidth.

On a quarterly view, Q2 looks weaker due to project timing, but H1 FY26 paints the real story: Revenue ₹4,157 mn (up 51.6%) and PAT ₹305 mn (up 133%).
Annualised EPS (based on H1) ≈ ₹61. So at ₹1,477, that’s a forward P/E of ~24x, cheaper than sector peers averaging 41x. Not bad for a company that literally makes sunlight pay rent.
Commentary: The growth is clearly real, not hot air. But the dip in Q2 profitability reminds us that solar EPC margins can swing faster than Indian monsoon moods. Still, the direction is bright — margin expansion from 10% to 15% shows efficiency improving with scale.
5. Valuation Discussion – Fair Value Range Only
We’ll value Solex using three lenses:
(a) P/E Method: EPS (annualised) = ₹61 Industry Average P/E = 41x Fair P/E Range = 25x–35x → Fair Value Range = ₹1,525 – ₹2,135
(b) EV/EBITDA Method: EV = ₹1,875 Cr EBITDA (TTM) = ₹102 Cr EV/EBITDA = 18.4x Industry Median ~20x → Fair EV/EBITDA Range (16–22x) → Implied Equity Value = ₹1,500 – ₹2,050 Cr
(c) Simplified DCF (Educational Estimate): Assuming 20% CAGR over 5 years, discount rate 12%, terminal growth 4% → Intrinsic range = ₹1,450 – ₹2,100
📘 Fair Value Range (Educational Only): ₹1,450 – ₹2,100 per share This range is for educational purposes only and is not investment advice.
