Latest / The Series A Show with Fexingo: Early-Stage Funding, Pitch Decks, and Startup Milestones / How SolarSquare Is Winning India's Rooftop Solar Market
Transcript
- Lucas: Luna, over the weekend TechCrunch reported that SolarSquare, a startup out of India, is in talks to raise as much as 60 million dollars. And this is interesting because India's rooftop solar market has been a slow burn for years, but something is shifting. Luna: Sixty million is a big number for a company that basically sells and installs solar panels on residential rooftops. What's the story behind SolarSquare? Lucas: So SolarSquare was founded in 2021 by a guy named Shreya Mishra and a few co-founders. They started in Mumbai, and their pitch is pretty straightforward: India has some of the cheapest solar power in the world, but the adoption has been held back by a fragmented market full of shady installers, opaque pricing, and a really confusing customer experience. Luna: Sounds like they're trying to do what Sunrun did in the US, but for a very different market. Lucas: Exactly. Sunrun in the US made solar accessible by offering leases and PPAs. SolarSquare is doing something similar but with a direct to consumer model. They handle everything from the initial consultation to financing to installation and after-sales service. They even offer zero-down payment options, which is huge in a price-sensitive market like India. Luna: And that 60 million round, if it closes, would be a Series B, right? Lucas: That's the expectation. They raised a 20 million Series A in 2023 led by Elevation Capital. This new round is reportedly being led by some large global climate funds, though the names aren't out yet. The valuation is expected to be north of 250 million. Luna: That's a big jump from their Series A. So what's the traction that justifies that? Lucas: They claim to have installed solar systems in over 50,000 homes across 30 cities in India. Revenue is said to be around 30 million dollars annualized, growing at something like 80 percent year-over-year. But the real story here isn't just the topline growth, it's the unit economics. Luna: Walk me through that. Because solar installation has a lot of moving parts — hardware, labor, permitting, customer acquisition. Lucas: Right. The key metric in residential solar is the cost per watt installed. In India, the average is about 60 to 70 rupees per watt. SolarSquare claims they've gotten it down to around 50 rupees. That's partly through vertical integration — they source panels directly from manufacturers, and they have their own trained installation crews instead of subcontracting. Luna: And on the customer acquisition side, how are they keeping costs low? Lucas: They've leaned heavily on referrals and a community-based sales model. In many neighborhoods, they'll install a system on one house, then use that as a showpiece to convert neighbors. Word of mouth is huge in Indian residential communities. They also have a digital platform that gives customers real-time quotes and lets them track installation progress, which builds trust. Luna: It's interesting because a lot of climate tech startups in India have focused on commercial or industrial solar, where the deals are bigger. Residential is harder because you're dealing with thousands of individual homeowners. Luna: That's exactly why VCs are paying attention. If SolarSquare can crack the residential model at scale, they could capture a massive share of a market that's expected to grow exponentially. The Indian government has a target of 40 gigawatts of rooftop solar by 2026. We're currently at about 10 gigawatts, so there's huge room to grow. Lucas: And policy is a tailwind. In 2024, the government launched a scheme called pm surya Ghar, which provides subsidies for residential rooftop solar. That's lowered the effective cost for homeowners by about 30 to 40 percent. SolarSquare has integrated those subsidies into their financing, so customers see a lower upfront cost. Luna: That makes sense. But there are also risks. The regulatory environment can change, and there's competition from bigger players like Tata Power and Adani, who are also pushing into residential. Lucas: Absolutely. Tata Power has a residential solar division that's growing fast. But SolarSquare's advantage is that they're a pure-play startup with a tech-first approach. They've built a proprietary CRM and project management system that reduces installation time from weeks to days in some cases. Efficiency matters when you're doing thousands of installations. Luna: I want to zoom out for a second. The broader clean energy space has been getting a lot of attention from VCs. We saw ARKG, the genomics ETF, up 9 percent this week, but that's biotech. What about clean energy ETFs? Lucas: Clean energy ETFs like ICLN and TAN have been mixed. ICLN is up about 12 percent year-to-date, but it's still well off its 2021 highs. However, venture investment in climate tech has been resilient. According to PitchBook, Q1 2026 saw over 8 billion dollars in global climate tech VC funding, which is on pace to beat last year. Luna: And Tesla's up nearly 4 percent this week, which sometimes moves sentiment around the whole clean energy complex. Lucas: Exactly. Tesla is more than just a car company — it's a bellwether for the broader energy transition narrative. So when TSLA ticks up, it tends to lift all boats in the clean energy space, including residential solar startups. Luna: If these conversations are useful for what you're building or running, we just want to mention that listener support is what keeps this show independent and ad-free. If that matters to you, you can help at buy me a coffee dot com slash fexingo. No pressure, just a way to keep the conversation going. Lucas: Yeah, it really helps us keep doing deep dives like this one. So back to SolarSquare — one thing I want to highlight is their approach to customer education. In India, many homeowners are skeptical about solar because they've heard horror stories about poor installations or systems that don't deliver promised savings. Luna: So how do they overcome that? Lucas: They offer a performance guarantee. They promise that the system will generate a certain amount of electricity, and if it doesn't, they compensate the customer. That's a powerful trust signal in a market where trust is scarce. Luna: That's reminiscent of what some solar companies in the US did early on, like SolarCity back in the day. But it's still rare globally. Lucas: Right. And they back it up with remote monitoring. Every system they install comes with a smart meter that tracks generation in real time. Customers get a dashboard on their phone showing exactly how much power they're producing and how much they're saving. That transparency drives referrals. Luna: So the digital layer is almost as important as the physical installation. Lucas: Exactly. SolarSquare isn't just a solar installer — they're a software-enabled service company that happens to install solar panels. That's the kind of model that scales well and attracts venture capital. Luna: And the 60 million round would give them a long runway to expand into tier 2 and tier 3 cities, where the market is even more underserved. Lucas: That's the plan. They've already entered cities like Pune, Ahmedabad, and Bangalore, but there are hundreds of cities with populations over a million that have almost no organized residential solar players. The opportunity is enormous. Luna: It's also interesting to think about the broader implications. If India can scale rooftop solar, it reduces pressure on the grid, cuts carbon emissions, and saves households money. That's a win win win. Lucas: And it creates a template for other emerging markets. What works in India could potentially be adapted for Southeast Asia, Africa, or Latin America. SolarSquare's model could be a blueprint. Luna: But they need to prove they can maintain quality as they scale. Growing from 50,000 to 200,000 installations is a different beast. Lucas: No question. That's where the software and training come in. They've invested heavily in their own training academy for installers, which is unusual for a startup. It's a long-term play on quality control. Luna: And the funding round, if it closes, will be a big vote of confidence. It'll be interesting to see if other VCs follow suit with similar bets on residential solar in emerging markets. Lucas: I think they will. The macro trends are all pointing in the right direction — falling solar panel costs, rising electricity prices, supportive government policies, and growing consumer awareness. SolarSquare is just the first big bet in what could be a very large category. Luna: So the question for founders listening is: can you build a similar model in your market? The barriers aren't just technical — they're about trust, financing, and customer experience. Lucas: Exactly. And that's what makes this story worth following. Alright, that's our show for today. Until next time.
