Residential solar company SolarSquare has raised USD 53 million in a Series C funding round led by B Capital, marking what the company describes as the largest funding round in India’s residential solar sector to date.
The round also witnessed participation from existing investors including Lightspeed, Lowercarbon Capital, Rainmatter, and Good Capital. With this latest investment, SolarSquare’s total capital raised has crossed USD 100 million since its inception.
The company plans to utilize the fresh capital to strengthen its market presence across India, expand into new cities, enhance its technology platform, and scale its installation and customer service operations. SolarSquare also intends to broaden its home-energy offerings by integrating solutions such as battery storage, financing, maintenance services, and energy management technologies.
Founded with a focus on accelerating rooftop solar adoption among homeowners, SolarSquare has installed solar systems across approximately 50,000 homes nationwide. The company currently operates at an annual revenue run rate exceeding INR 1,000 crore and has emerged as one of the leading players in India’s residential solar segment.
According to the company, India’s residential rooftop solar market is witnessing rapid growth, supported by rising electricity tariffs, favorable government policies, and increasing consumer awareness regarding clean energy solutions. The launch of the PM Surya Ghar: Muft Bijli Yojana has further strengthened demand for rooftop solar installations across the country.
SolarSquare estimates that India has nearly 70 million suitable residential rooftops with significant untapped potential for solar adoption. The company believes the market remains at an early stage of development, presenting substantial opportunities for long-term growth.
The funding round reflects increasing investor confidence in India’s distributed renewable energy sector and highlights the growing attractiveness of residential solar as a scalable and technology-driven business segment. Industry observers note that venture capital interest in consumer-focused clean energy companies is rising as the country advances its energy transition and decarbonization goals.
With the new funding in place, SolarSquare aims to accelerate its mission of making rooftop solar more accessible to Indian households while building a comprehensive home-energy ecosystem designed to reduce electricity costs and promote sustainable energy consumption.
