Mumbai-based rooftop solar startup SolarSquare Bags Bold backing of $55 Mn (Rs 458 Cr) in a new Series C round led by B Capital and Lightspeed Venture Partners, valuing it at nearly $500 Mn (Rs 4,150 Cr).
The round more than doubles the company’s valuation in about 18 months, per multiple people familiar with the deal. Existing investor Elevation Capital also joined. The raise lands as venture investors step up bets on India’s fast-growing residential solar market.
StartupFeed Insight
The real signal here is not the dollar figure, it is the math. SolarSquare’s valuation jumped 2.5 times while its FY25 revenue of Rs 364 Cr (Tracxn) suggests an annualised run rate now past Rs 10 Bn. That gap means investors are paying for the market, not just the books. Founders, installers, and Tata Power should watch how fast SolarSquare converts its 200 MW residential target into recurring maintenance revenue. StartupFeed predicts a fourth raise or an IPO filing within 24 to 30 months if the company holds its run rate and trims losses. Vertical integration is the bet that decides it. By StartupFeed Desk.
Deal Breakdown and Numbers
SolarSquare’s Series C is a $55 Mn (Rs 458 Cr) primary raise co-led by two growth investors. The round prices the company near $500 Mn (Rs 4,150 Cr), per people familiar with the matter (TechCrunch).
| Metric | Detail | Notes |
|---|---|---|
| Total Raise | $55 Mn (Rs 458 Cr) | Series C primary round (TechCrunch) |
| Lead Investors | B Capital, Lightspeed | Lightspeed via its growth fund |
| Other Participant | Elevation Capital | Existing investor |
| Valuation | $500 Mn (Rs 4,150 Cr) | Up 2.5x from $200 Mn (Dec 2024) |
| Previous Round | $40 Mn Series B | December 2024, led by Lightspeed |
| Cumulative Raised | ~$61.1 Mn (pre-Series C) | Across 4 prior rounds (Tracxn) |
The standout number is the valuation jump. SolarSquare’s worth rose 2.5 times in roughly 18 months, even though its last Series B closed at just $200 Mn (TechCrunch).
About SolarSquare
SolarSquare designs, installs, and maintains rooftop solar systems for homes and housing societies. Founded in 2015 by Shreya Mishra, Neeraj Jain, and Nikhil Nahar, the Mumbai company began as a B2B solar firm before pivoting to residential rooftop solar in 2021. It has installed over 150 MW across 29 cities in nine states (company data). Top investors include Lightspeed, Elevation Capital, and Rainmatter.
Why Did B Capital Back SolarSquare?
B Capital backed SolarSquare because India’s residential solar market is large, fragmented, and growing fast. The startup’s full-stack model, owning design, install, and service, sets it apart from dealer-led rivals.
“Only 1% of homes in India have adopted solar so far. We want to accelerate solar adoption by making it easy for families to switch,” said Shreya Mishra, CEO, SolarSquare.
That low penetration is the thesis. India set a target of 500 GW of renewable capacity by 2030, with solar tipped to supply over half (TechCrunch). SolarSquare wants the household share of that wave.
How Will SolarSquare Use the Funds?
SolarSquare will use the funds to deepen its residential push over the next two years. Plans cover building its technology stack, hiring talent, and investing in brand-building, per people familiar with the matter (TechCrunch).
The company has crossed an annualised revenue run rate above Rs 10 Bn (around $104 Mn) across homes and societies. It aims to reach 200 MW in its residential solar portfolio this year, scaling back lower-margin industrial work.
Who Are SolarSquare’s Rivals?
SolarSquare competes in a market dominated by large brands selling through dealer networks. Its full-stack control is the main difference.
| Company | Model | Edge |
|---|---|---|
| SolarSquare | Full-stack residential | Owns end-to-end customer journey |
| Tata Power Solar | Dealer and EPC network | Brand trust, scale |
| Waaree Energies | Manufacturer plus installs | In-house panel supply |
What sets SolarSquare apart is vertical integration, which is harder to scale than a dealer model but builds stronger customer retention (TechCrunch).
What’s Next
The near-term milestone is clear: hit 200 MW in residential capacity this year while keeping the Rs 10 Bn run rate intact. Watch for a formal funding close announcement and city expansion beyond the current 29 markets in the next two quarters. If SolarSquare trims losses alongside growth, an IPO conversation could open sooner than expected. Could rooftop solar become India’s next big consumer IPO story?
