India's solar pioneer since 1999

Engineering-led. MNRE certified. Two decades of setting benchmarks in technology, scale, and customer impact. From introducing India’s first ETC water heater to delivering large-scale EPC projects.

Founded on a belief

Founded in 1999 on a simple belief, that India’s abundant sunshine is one of its most powerful, yet underutilized resources. Over the past 25 years, we have built on this conviction, translating solar potential into reliable, efficient solutions across diverse applications.

Retail and large-scale EPC

We operate across two distinct verticals: a retail and distribution arm delivering solar thermal systems, heat pumps, and solar PV components, and an EPC division that engineers and executes solar installations across diverse sectors.

Certified, tested, proven

MNRE certified since 2002. BIS-ISI approved. UNDP-recognised as India’s best solar water heater brand. ISO quality managed. Every system we deliver is built on field-tested technology and backed by our in-house engineering team.

Mr. R. S. Sethurraman

Chairman, Solar Hitech Solutions Pvt. Ltd.

"I started Solar Hitech in 1999 because I believed India's climate was a gift we had not yet learned to use. Forty years in manufacturing taught me that quality is never an accident, it is always the result of intelligent effort.

At Solar Hitech, our journey has always been driven by a simple belief, to build a self-sustaining and profitable clean technology company that delivers solutions designed to outlive us and create a greener planet for generations to come.

Our vision is to ensure that every project we deliver becomes a benchmark for quality, reliability, and trust in clean energy, while making solar accessible, affordable, and dependable for businesses and communities alike.

We pursue this vision through uncompromising transparency, strong engineering practices, and a commitment to long-term partnerships, building a brighter and more sustainable future, one rooftop at a time.

Part of something larger

Solar Hitech’s work sits at the heart of India’s clean energy transition — from PM Surya Ghar driving rooftop adoption to industrial decarbonisation reshaping how factories source power. We are not observers of this shift. We are its practitioners.

Why we operate both

Our retail business gives us direct feedback from thousands of installations — which makes our EPC engineering more practical and cost-effective. When we specify a component in a ₹5 Crore project, we already know how it behaves in the field. That knowledge loop is a genuine competitive advantage for our EPC clients.

Leadership

Solar Hitech is led by a family whose combined experience spans manufacturing, engineering, project delivery and market development across four decades and two generations of clean energy expertise.

R. S. Sethurraman

Chairman

With over 40 years in precision manufacturing, Mr. R. S. Sethurraman founded Solar Hitech Solutions in 1999, recognising India’s solar thermal energy potential. He introduced the country’s first ETC water heater and holds patents in solar water control technology for apartments.

"Quality is the foundation on which every lasting business is built. We have never compromised on it, and we never will."
