Summary
India’s solar boom has a pre-IPO contender: Sun Drops Energia. Backed by listed parent KPI Green, it has grown revenue at a 173% three-year CAGR while keeping debt-to-equity at just 0.11. Now it’s adding battery storage to its solar mix. Our FY30 valuation points to ~171% upside from ₹318, a 28% CAGR, driven purely by earnings growth. Small today, but clearly built to scale. Here’s the full story behind the numbers.
India's renewable energy sector is expanding at remarkable speed. The country ranks third globally in installed renewable capacity, and Mordor Intelligence expects the installed base to grow from 241.2 GW in 2025 to 486 GW by 2030, a CAGR of about 15%. Solar leads the way. At roughly 164.8 GW as of June 2026, India has overtaken Japan as the world's third-largest solar producer. IBEF estimates the sector could draw over US$ 250 billion in investments by 2030 including US$ 15.5 billion for solar PV and US$2.7 billion for battery manufacturing.
Sun Drops Energia Limited sits in the middle of this shift. Founded in 2019, it is the unlisted solar arm of the KP Group and a subsidiary of KPI Green Energy, which holds 65.87%. Founder Dr. Faruk G. Patel holds another 13.13%.
Sun Drops runs on a mix of revenue streams. As an Independent Power Producer, it builds and owns plants and sells power under long-term agreements, which gives it steady annuity-style cash flows. As an EPC partner for captive power producers, it builds plants for businesses that want to generate their own electricity, recognising revenue as projects progress. Its total IPP and CPP portfolio stands at over 982 MWp. It has also been named the group's vehicle for Battery Energy Storage Systems (BESS), a segment still in its early days in India.

The numbers show rapid growth without heavy borrowing. Revenue surged 484% in FY24, and the three-year revenue CAGR is 173%. Debt-to-equity fell from 0.56 in FY23 to just 0.11 in FY26, which means expansion was funded largely by internal accruals and leaves room to borrow for future projects. Return ratios cooled after the FY24 spike as the equity base widened, but ROCE has consistently stayed above ROE.



Our forward P/E model projects revenue growth stepping down from 60% to 25% by FY29-30, with a flat 16% PAT margin and a 28x multiple. On that basis, the FY30 value implies about 171% upside on the current unlisted price of ₹318, a CAGR of roughly 28%. Margins and the multiple are held constant, so the return depends entirely on earnings growth. It is an execution story rather than a bet on market sentiment.

Against its listed parent, Sun Drops has about one-fifth of KPI Green's revenue and lower margins, yet carries a market capitalisation that is high relative to its share of group earnings. The market appears to be paying for growth. It also converts EBITDA into profit more efficiently than its parent, helped by lower leverage.
Scale is the main weakness, along with a heavy concentration of operations in Gujarat. Competition in solar is fierce, and policy changes, approval delays and volatile input costs could all squeeze execution.
Sun Drops Energia is a small but fast-growing solar and battery-storage platform. It combines strong parentage, a diversified revenue base, a lean balance sheet and early exposure to energy storage. A planned IPO could bring liquidity and fresh capital. The investment case rests on the company continuing to deliver the growth it has shown so far.
