Exciting Times Ahead for SolarSquare as New Funding Round Approaches
SolarSquare, an innovative startup helping Indian households and housing societies harness solar power, is reportedly in advanced discussions to secure fresh funding. This comes on the heels of the company raising India’s largest solar venture investment in December 2024, according to sources close to the matter.
Major Investors in the Spotlight
Leading investment firms B Capital and Lightspeed Venture Partners are poised to co-lead SolarSquare’s Series C funding round, which may value the startup between $450 million and $500 million. This funding round is expected to bring in an estimated $55 million to $60 million in new investments. This would mark a significant increase in SolarSquare’s valuation, potentially more than doubling in just 18 months, reflecting the growing investor confidence in India’s residential solar market.
A History of Investor Support
Lightspeed Venture Partners, which previously led SolarSquare’s $40 million Series B round with a post-money valuation of around $200 million, is once again stepping up. This time, the firm is investing through its growth fund, which has also backed well-known companies like Razorpay and Zepto.
Continued Participation from Existing Investors
Notably, Elevation Capital, a returning investor, is expected to join in the upcoming funding round, which is in its final stages and anticipated to close next month. While details are still being finalized, SolarSquare has already raised $61.1 million in equity financing according to the startup data platform, Tracxn.
India’s Solar Ambitions
India is on a clear path to achieve a target of 500 gigawatts of renewable energy capacity by 2030, with solar power projected to contribute more than half of that capacity. The country ranked as the third-largest solar power producer in 2025, following China and the U.S. Since 2014, India’s cumulative installed solar capacity has expanded dramatically from approximately 3 GW to over 150 GW as of 2026. This surge has been significantly bolstered by government incentives and subsidy schemes aimed at promoting rooftop solar adoption.
SolarSquare’s Growing Footprint
Founded in 2015 and headquartered in Mumbai, SolarSquare is working to establish itself as a comprehensive residential solar platform in a highly fragmented market dominated by small local installers and dealer networks. The startup is involved in designing, installing, and maintaining rooftop solar systems for homes, housing societies, and enterprises. To date, it has installed over 150 megawatts of solar capacity across 29 cities in nine states.
Powering Thousands of Homes
According to sources, SolarSquare has successfully powered nearly 50,000 homes and approximately 400 housing societies. Additionally, it has implemented rooftop solar systems for various large enterprises, including renowned names like Swiggy, Zepto, and iD Fresh Food.
Shift in Business Strategy
Recent reports indicate that residential customers and housing societies now constitute the majority of SolarSquare’s business. The startup is focusing on scaling back lower-margin industrial rooftop projects in favor of lucrative residential opportunities.
Impressive Revenue Growth
Currently, SolarSquare has achieved an annualized revenue run rate exceeding ₹10 billion (approximately $104 million), thanks to its expanding business in residential services. The startup aims to grow its residential solar portfolio to 200 megawatts this year, signifying its aggressive growth strategy moving forward.
Awaiting Comment from Stakeholders
As of now, SolarSquare has opted not to comment on the discussions. Efforts to reach out to B Capital, Lightspeed Venture Partners, and Elevation Capital for comments have gone unanswered.
The Bigger Picture
The upcoming funding round could further elevate SolarSquare’s position within the growing Indian solar market, aligning with the nation’s ambitious renewable energy goals. As the world turns its focus to sustainable energy solutions, the advancements made by startups like SolarSquare are crucial. For more insights on startups and technology, visit Axom Live.
