SolarSquare has raised $53 million (approximately ₹510 crore) in a Series C funding round led by existing investor Lightspeed, further strengthening its position as one of India’s fastest-growing clean energy startups. The round also saw participation from existing investors Elevation Capital, Lowercarbon Capital, Rainmatter, and Good Capital, highlighting strong investor confidence in India’s rapidly expanding renewable energy ecosystem.
The latest investment marks a major development in D2C funding news and India’s broader startup landscape. As demand for sustainable energy solutions continues to rise, SolarSquare is emerging as a key player helping homeowners transition to cleaner, more affordable energy sources. The fresh capital will be used to expand into new cities, strengthen technology capabilities, scale its platform, and accelerate hiring as the company prepares for its next phase of growth.
Founded in 2015 by Shreya Mishra, Neeraj Jain, and Nikhil Nahar, SolarSquare initially focused on serving enterprise customers before entering the residential segment in 2021. Today, the company operates as a full-stack residential solar brand, managing everything from design and installation to financing, maintenance, after-sales support, and energy management solutions. This integrated approach has helped SolarSquare build a strong reputation among homeowners seeking reliable rooftop solar solutions.
The company has now raised more than $100 million in total funding and has already served nearly 50,000 homes across India. SolarSquare currently reports an annual revenue run rate (ARR) of approximately ₹1,000 crore, underscoring the growing consumer demand for residential solar adoption. Such strong D2C revenue growth reflects the broader momentum within India’s clean technology sector and positions SolarSquare among the fastest-growing startups in the country.
India’s rooftop solar market is witnessing unprecedented growth, supported by government initiatives such as the PM Surya Ghar scheme, rising electricity costs, increasing environmental awareness, and improved financing accessibility. According to industry estimates, India has nearly 70 million viable residential rooftops capable of supporting solar installations, creating a massive long-term market opportunity.
SolarSquare’s expansion plans align closely with several D2C market trends 2025, where technology-enabled consumer businesses are solving large-scale infrastructure challenges through digital platforms and integrated service models. The company is also working toward building a comprehensive energy ecosystem that includes solar installation, battery storage solutions, financing services, home energy management systems, and long-term maintenance support.
Investor interest in clean technology continues to strengthen as sustainability becomes a key investment theme globally. Recent D2C funding rounds and climate-focused investments demonstrate increasing confidence in startups addressing energy transition challenges. SolarSquare’s latest raise further validates the growing attractiveness of India’s cleantech ecosystem and its potential to generate both environmental impact and financial returns.
Beyond business growth, the company’s mission aligns with India’s broader energy transition goals. As renewable energy adoption accelerates, residential solar solutions are expected to play a crucial role in reducing carbon emissions, lowering household energy costs, and improving energy independence. SolarSquare’s technology-driven approach makes solar adoption easier and more accessible for consumers across the country.
The company’s expansion also reflects the evolution of the D2C business model India, where brands increasingly own the entire customer journey rather than focusing solely on product delivery. By combining technology, financing, installation, and long-term service support, SolarSquare has created a scalable and defensible business model that continues to attract both customers and investors.
As India’s cleantech economy moves toward becoming a projected $152 billion opportunity by 2030, SolarSquare appears well-positioned to capture a significant share of the market. With fresh capital, strong investor backing, a ₹1,000 crore ARR, and a rapidly growing customer base, the company is entering a new chapter of expansion while helping accelerate India’s transition toward sustainable energy solutions.
