India's SolarSquare is securing $60 million at a valuation of $500 million. It has provided energy to 50,000 households.

      **TL;DR:** SolarSquare is in the process of raising between $55 million and $60 million at a valuation ranging from $450 million to $500 million, according to TechCrunch. This funding round, led by B Capital and Lightspeed, would significantly increase SolarSquare’s valuation compared to 18 months ago, when it was estimated at around $200 million during its $40 million Series B funding in December 2024. The current funding has yet to finalize, and the terms may still be subject to change. To date, SolarSquare has raised $61.1 million in equity, and the funding round is anticipated to close next month.

      Founded in 2015 and based in Mumbai, SolarSquare focuses on designing, installing, and maintaining rooftop solar systems for homes, housing societies, and businesses. The company has successfully installed over 150 megawatts of capacity across 29 cities in nine states, powering nearly 50,000 homes and about 400 housing societies. Major enterprise clients include Swiggy, Zepto, and iD Fresh Food, with residential and housing society clients now making up the majority of their business as the company moved away from lower-margin industrial projects.

      SolarSquare has surpassed an annualized revenue run rate of ₹10 billion (approximately $104 million) and aims to achieve a residential solar portfolio of 200 megawatts this year. Its growth is fueled by India's fragmented rooftop solar market, which is primarily served by small local installers.

      In 2025, India became the world's third-largest solar power producer, following China and the US. The nation’s cumulative installed solar capacity increased from about 3 GW in 2014 to over 150 GW in 2026. The government has set a goal of reaching 500 GW of renewable energy capacity by 2030, with solar expected to make up more than half. Subsidies have played a crucial role in promoting residential solar adoption, particularly through the PM Surya Ghar Muft Bijli Yojana scheme, which subsidizes up to 60% of rooftop solar installation costs for households. SolarSquare aims to become a full-stack platform that effectively captures this growing demand.

      However, the global solar narrative presents a paradox, with India rapidly advancing in rooftop solar deployment while contrastingly, Elon Musk’s xAI is powering data centers using $2.8 billion in gas turbines. Despite Tesla’s solar division generating significant quarterly revenue, it is overlooked by Musk's AI business. SolarSquare’s expansion reflects the viability of terrestrial solar economics on a consumer scale, even as the AI sector explores alternative paths.

      India's tech adoption is facing challenges from various angles, including a 59% year-on-year collapse in the sub-$100 smartphone market in Q1 2026 due to rising memory prices. As the nation increases its rooftop solar installations, it simultaneously struggles to maintain access to affordable smartphones. SolarSquare contributes to the necessary infrastructure that supports India's digital economy; without accessible power, the technological framework cannot function.

      The competitive landscape features players like Tata Power, Waaree Energies, Luminous Power Technologies, and Exide Industries, which operate through dealer networks and local partnerships. SolarSquare's edge lies in its vertical integration strategy, managing the customer relationship from the initial design phase through installation and ongoing maintenance. Although this model is more challenging to scale compared to dealer networks, it fosters stronger customer loyalty.

      SolarSquare did not provide a comment, and B Capital, Lightspeed, and Elevation Capital did not respond to inquiries. If the funding round concludes as reported, it will represent one of the largest venture investments in India's clean energy sector this year.
