B Capital Leads Fresh Funding Round as SolarSquare Crosses $100 Million in Total Capital Raised

Indian residential solar startup SolarSquare has raised $53 million in a Series C funding round led by B Capital, with continued backing from existing investors Lightspeed, Elevation Capital, Lowercarbon Capital, Rainmatter by Zerodha, and Good Capital. With this latest investment, the Mumbai-based company has now raised more than $100 million to fuel its long-term growth plans.

Funding to Drive Expansion and Technology Development

The fresh capital will be used to expand SolarSquare’s presence into new cities across India, strengthen its technology infrastructure, recruit top talent, and further enhance its platform. The company aims to make rooftop solar more accessible for homeowners while improving customer experience through advanced digital solutions and integrated services.

As demand for clean energy continues to grow, SolarSquare plans to strengthen its leadership position in India’s rapidly expanding residential solar market.

Building a Full-Stack Residential Solar Platform

Founded in 2015 by Neeraj Jain, Nikhil Nahar, and Shreya Mishra, SolarSquare operates as a vertically integrated home energy company. Rather than offering only solar panel installation, the startup manages the complete customer journey—from consultation and system design to financing assistance, installation, maintenance, and after-sales support.

This end-to-end approach addresses many of the challenges in India’s traditionally fragmented residential solar industry by providing homeowners with a single trusted platform.

The company says it has already served approximately 50,000 households across the country and is currently operating at an annual revenue run rate of over ₹1,000 crore, reflecting the growing adoption of rooftop solar solutions in India.

Leadership Highlights India’s Solar Opportunity

Commenting on the funding, Shreya Mishra, CEO and Co-founder of SolarSquare, said the company had made an early bet on residential solar when the sector was still in its infancy. She noted that while only around one lakh homes adopted rooftop solar annually five years ago, that number has now increased dramatically, with nearly one lakh homes switching to solar every ten days.

She added that SolarSquare aims to become the operating system for India’s home energy transition by expanding beyond solar installations into financing, battery storage, home energy management, and long-term service support.

Investors Remain Bullish on Residential Solar

B Capital’s General Partner Karan Mohla said India’s clean energy transition will be driven not only through large-scale infrastructure but also by widespread household adoption. He highlighted SolarSquare’s strong business fundamentals, technology capabilities, and scalable operating model as key reasons behind the firm’s investment.

Lightspeed India Partner Rahul Taneja added that the investment firm has continued to support SolarSquare because of its strong execution, customer trust, and full-stack business model. He said the company’s focus on operational excellence and performance guarantees has reinforced investor confidence.

As India’s residential solar market continues to expand, SolarSquare is positioning itself to play a major role in helping homeowners transition to clean, reliable, and affordable energy solutions.
