Started with Just Rs 15,000 Capital, This Bootstrapped Startup Now Powers 8,000 Rooftops Across India

In 2016, Kuldip Sorathiya stood at a crossroads. Born into a farming family in Gujarat's Kolda village and burdened by Rs 17 lakh in family debt, he had just seen his dream of studying in Canada collapse after being denied an education loan.

But where one door closed, another opened. A year later, with just Rs 15,000 in savings, Kuldip launched Ksquare Energy from a 150 sq. ft. rented room in Ahmedabad.

That small bet has since grown into one of India's most dynamic solar companies, serving over 8,000 households, supplying to more than 650 EPC firms, and ranking among the top 10 vendors under the PM Surya Ghar Yojana.

A Pan-India Solar Force

Seven years later, Ksquare Energy has grown into a 130-member company with a footprint across 23 states. The company operates out of warehouses in Ahmedabad, Pune, Lucknow and Bengaluru.

According to Mercom India, rooftop solar installations surged 232% year-on-year in Q1 2025, touching over 1.2 GW.

A standout initiative is its 5-Year Zero Loss Guarantee, which compensates clients if systems remain non-functional beyond 48 hours.

Solsquare Cable Brand

The company launched Solsquare, its proprietary brand of solar and electrical cables, housed in a 4,500 sq. ft. manufacturing and R&D facility. The company produces modular DCDBs and IoT-ready combiner boxes.

Profitable Since Inception

Ksquare posted Rs 74 crore in revenue for FY 2023–24 and has remained profitable since inception. It reported 56% year-on-year growth and has set a target of Rs 225 crore by FY 2025–26, with an ambitious goal to cross Rs 1,000 crore by 2030.

The company has been entirely bootstrapped but is now open to raising strategic capital.
