Five years ago, residential solar in India was largely invisible to mainstream investors, underfunded compared to utility-scale projects, and perpetually described as "nascent”. Today, SolarSquare is making that story impossible to ignore. SolarSquare, India’s leading residential solar brand, has raised $53 million in a Series C funding, marking the largest venture investment in India’s solar sector. The round was led by B Capital, with existing investors Lightspeed doubling down on the company. Other existing investors, Elevation Capital, Lowercarbon Capital, Rainmatter by Zerodha and Good Capital, also returned to participate in the current round. This takes the total capital raised by the company to over $100mn. The fresh capital will be deployed to accelerate geographic expansion into new cities, deepen SolarSquare’s technology capabilities, hire talent and scale the platform to capitalise on this generational opportunity to become India’s most trusted new age home-energy brand. Founded by Neeraj Jain, Nikhil Nahar and Shreya Mishra, the raise marks a defining moment for SolarSquare, and for the broader category they have spent a decade building in. Since its founding in 2015, the company has grown into India’s largest residential rooftop solar brand, having powered ~50,000 homes across the country and currently running at a rate of over 1000 Cr in revenues. The timing of the raise reflects a fundamental shift in how Indian homeowners are thinking about energy. India’s electricity tariffs have been climbing steadily and investment in residential solar breaks even in less than 5 years across India. Rising electricity costs, a volatile global environment and India’s growing energy needs are all converging to decentralised rooftop solar as the answer, benefitting consumers and the country. The central government’s PM Surya Ghar scheme has seeded consumer awareness at a scale no marketing budget could replicate. SolarSquare operates as a full-stack home energy platform. The company manages the entire customer journey, from initial consultation and system design to installation, financing support, and long-term maintenance - a vertically integrated model built for a market that has historically been fragmented and unorganised. Rooftop solar requires a capital commitment of anywhere between ₹2-4 lakh for a typical urban household. That kind of decision demands trust, transparency, and reliable after-sales support. SolarSquare’s integrated model is built precisely around that insight. It is the first in India to offer a performance guarantee to its customers, an innovation that gives customers complete assurance on their investment. Underpinning this is a proprietary technology and operations platform that today manages India's largest portfolio of residential solar assets - at scale, and with a performance guarantee attached to every system. B Capital anchoring the round brings deep global pattern-recognition to a market that has often been underes
