Summary

SolarSquare, an Indian rooftop solar startup, is in advanced discussions to secure \$55 million to \$60 million in a Series C funding round. B Capital and Lightspeed Venture Partners are expected to co-lead this investment, which could value the company between \$450 million and \$500 million, more than doubling its valuation in 18 months. This reflects strong investor confidence in India's residential solar market, which aims for 500 gigawatts of renewable energy by 2030. SolarSquare, founded in 2015, operates as a full-stack platform, designing, installing, and maintaining rooftop solar systems for nearly 50,000 homes and 400 housing societies across 29 cities. The company has installed over 150 megawatts of solar capacity and achieved an annualized revenue run rate exceeding ₹10 billion (approximately \$104 million) from residential projects.

Key takeaway

For investors evaluating high-growth emerging markets, India's residential rooftop solar sector offers compelling opportunities, as evidenced by SolarSquare's rapid valuation increase to \$450M-\$500M and its \$55M-\$60M Series C round. Entrepreneurs should note the success of full-stack models in fragmented markets and the strategic shift towards higher-margin residential projects. Aligning with strong government renewable energy targets can further de-risk and accelerate market entry.
