SolarSquare: Decoding Market Trends, Tenders, and Rooftop Solar Financing

Grab a coffee. Let us talk about building something massive in the Indian cleantech space. Building a startup is never a straight line. It is messy. It is loud. You constantly second-guess yourself. But when you look at the residential solar market in India, you see a massive wave. SolarSquare is riding that exact wave right now.

What is SolarSquare?

The reality is, most people look at rooftop solar and see a logistical nightmare. SolarSquare looked at it and saw a consumer brand. They are a cleantech company designing, installing, and financing residential solar systems.

They operate across 29 cities in nine states. And they are serving nearly 50,000 households and 400 residential communities. That is a serious scale. But they do not just stop at homes. They have deployed systems for commercial giants like Swiggy, Zepto, and iD Fresh Food. Their total installed capacity has crossed 150 megawatts. Getting to that number is not luck. It requires building a machine. They are capitalizing on the PM Suryaghar scheme, which gives households up to 40% in subsidies. Residential customers remain their absolute core focus.

SolarSquare Funding and Valuation

Let’s be honest. Capital follows momentum. According to TheKredible, SolarSquare had raised around $56 million before their latest massive moves.

In December 2024, they closed a $40 million Series B round. Lightspeed spearheaded that round with $14.2 million. Lowercarbon Capital threw in $8.1 million. You also had Elevation Capital, Gruhas Proptech, and Zerodha’s Nithin Kamath jumping in. After that round, the company was valued at roughly $209 million. That alone is a solid win.

Here is the kicker. They are already nearing a Series C round of $55 million to $60 million. B Capital and Lightspeed are expected to co-lead this one. This new deal will double their valuation to somewhere between $450 million and $500 million in just 18 months. Investors are betting heavy on India’s target of 500 GW renewable capacity by 2030.

SolarSquare Founders and History

So how did they get here? It started back in 2015. Neeraj Jain and Nikhil Nahar founded the company as a pure B2B commercial solar business. They bootstrapped it. They pushed it to around Rs 100 crore in annual top line over five years. That takes guts. Bootstrapping teaches you discipline.

Then Shreya Mishra joined as the third co-founder in 2020. By 2021, the founders looked at the board and decided to pivot completely. They went all in on the B2C residential market to build a home energy brand. Walking away from a stable B2B cash flow to chase a messy consumer market is terrifying. It’s lonely. It’s hard. But it works. That pivot changed the DNA of the company.

SolarSquare Revenue and Losses

Growth eats cash. That is just the law of gravity in startups. In the fiscal year ending March 2024, their operating revenue jumped by over 60% to reach Rs 175 crore. Product sales brought in the lion’s share at Rs 173 crore.

But here is the painful part. Expenses skyrocketed to Rs 229 crore. Material costs ate up Rs 134 crore, and employee benefits doubled to Rs 37 crore. As a result, losses surged 2.3 times to Rs 69 crore.

They literally spent Rs 1.31 to earn a single rupee in FY24. Their return on capital employed hit a brutal -112.85%, and the EBITDA margin sat at -35.96%. They are one of the priciest installers in a highly value-conscious market. But look at the upside. Their annualized revenue run rate for residential and community projects has now crossed Rs 10 billion, or roughly $104 million. You bleed in the short term to capture the market in the long term.

Execution is everything. You can have the best sales pitch in the world, but if your product delivery is sloppy, you die. SolarSquare figured out how to use modular and prefabricated installation designs. The industry standard for installing a home solar system takes three to five days. SolarSquare does it in just eight hours. That is a massive operational moat.

And the value proposition for the buyer is clear. Each home saves an average of Rs 48,000 a year on electricity bills. They also offset 4 metric tons of CO₂ annually. To grease the wheels even more, the company has plans to launch an in-house non-banking financial company. This will let them extend loans directly to residential buyers. Make it easy to buy, and people will buy.
