SolarSquare Eyes $60M Funding Boost as India’s Rooftop Solar Market Hits a Turning Point
Table of Contents
A New Valuation Milestone
SolarSquare, the Mumbai-based residential solar platform, is currently in advanced negotiations to secure up to $60 million in a fresh funding round. The Series C injection is expected to be co-led by B Capital and Lightspeed Venture Partners, a move that could push the company’s valuation into the $450 million to $500 million range, according to sources familiar with the deal.
This projected valuation represents a staggering leap for the company, more than doubling its worth in roughly 18 months. The momentum follows a significant $40 million Series B round led by Lightspeed in December 2024, which valued the startup at approximately $200 million. The current interest suggests a shift in investor sentiment, moving from cautious exploration of the green-tech sector to aggressive conviction in the scalability of India’s rooftop solar market.
Elevation Capital, an existing investor, is also expected to participate in the round, which is slated to close next month. While terms remain subject to finalization, the capital injection comes at a time when SolarSquare is attempting to institutionalize a fragmented installation market.
Scaling the Residential Maze
The Indian rooftop solar landscape has historically been a patchwork of small-scale local contractors and dealer networks tied to legacy hardware manufacturers like Tata Power, Waaree Energies, and Luminous Power Technologies. SolarSquare is attempting to disrupt this by positioning itself as a full-stack provider, handling everything from design and permitting to installation and long-term maintenance.
The company’s strategic pivot is evident in its customer mix. While it previously handled industrial projects, SolarSquare has increasingly distanced itself from low-margin industrial rooftop work to double down on homes and housing societies—the dense apartment complexes and gated communities that define urban Indian living. This shift has paid off; the company has reportedly surpassed an annualized revenue run rate of ₹10 billion (approximately $104 million) across these two segments.
Currently, the startup operates across 29 cities in nine states, having installed over 150 megawatts of capacity. This footprint includes nearly 50,000 individual homes and roughly 400 housing societies. Beyond the residential sector, the company has also secured enterprise clients such as Swiggy, Zepto, and iD Fresh Food, integrating sustainable energy into the infrastructure of India’s booming quick-commerce and food-tech sectors.
The Macro Push Toward 2030
SolarSquare’s growth is intrinsically linked to India’s aggressive climate targets. The national goal to achieve 500 gigawatts of renewable energy capacity by 2030 relies heavily on solar, which is expected to provide more than half of that total. The scale of the transition is visible in the data: cumulative installed solar capacity surged from a mere 3 GW in 2014 to over 150 GW by 2026.
This growth has been fueled by a combination of government subsidies and incentive schemes designed to lower the barrier to entry for homeowners. As the world’s third-largest solar power producer, trailing only the U.S. and China, India is seeing a convergence of regulatory support and consumer demand that creates a fertile environment for platforms like SolarSquare to scale.
The company has set an ambitious target to reach 200 megawatts in its residential solar portfolio within the current year. Whether they can maintain this trajectory will depend on their ability to navigate the logistical complexities of urban installation and the volatility of component pricing.
SolarSquare declined to comment on the funding talks. B Capital, Lightspeed Venture Partners, and Elevation Capital also did not respond to requests for comment.
