SolarSquare, the Mumbai-based residential solar startup, has raised ₹510 Cr (approximately $53M) in a Series C funding round led by B Capital, as publicly reported on 16 June 2026. The round saw participation from a strong consortium of existing and new backers, underlining sustained investor conviction in India’s home-energy transition. It is worth noting that a minor conflict exists in public reporting regarding the lead investor; multiple sources confirm B Capital as the lead, with Lightspeed participating as an existing backer — this article reflects the majority-verified account.

Funding Breakdown
Use of Funds
The Series C proceeds will be deployed across four priority areas: geographic expansion into new Indian cities, strengthening of SolarSquare’s technology platform, talent acquisition, and scaling of its battery storage and energy management offerings. The capital marks a deliberate push beyond pure solar installations toward a broader home-energy stack.
Funding Timeline
With this Series C close, SolarSquare’s cumulative venture funding crosses $100M. The company has not publicly detailed prior round sizes in the verified data available; this Series C represents the most recent and, by publicly reported figures, the largest single raise in its history.
Expansion Plans
SolarSquare intends to extend its footprint to new Indian cities beyond its current markets, broadening access to residential solar installations and associated financing products. In parallel, the company plans to build out a full home-energy platform encompassing solar, battery storage, and energy management services — positioning itself as an integrated energy provider rather than a single-product installer. Hiring across technical and operational roles is also planned as part of this growth push.
Significance
This round is publicly reported as the largest venture capital investment ever made in India’s residential solar sector, a milestone that signals the market is maturing from early-stage experimentation to institutional-scale capital deployment. SolarSquare’s reported annual recurring revenue of ₹1,000 Cr provides the kind of revenue foundation that justifies a growth equity-sized cheque from a firm like B Capital. The breadth of the investor syndicate — spanning climate-focused funds such as Lowercarbon Capital, fintech-adjacent backers like Rainmatter, and mainstream growth investors — reflects the convergence of climate and consumer tech narratives in India. As rooftop solar policy tailwinds continue and battery storage costs decline, this raise could catalyse further large-ticket investments across the residential clean-energy segment.
