From Tamil Nadu to Munich
How the Solar PCU Took India to the World Stage — 90+ Countries
Kunwer Sachdev
Solar Man of India
Founder of Su-Kam Power Systems (1998–2019). Took solar to 90+ countries, built India's largest solar dealer network, and won the ISA Technovation Award. Now documenting the untold story of India's solar revolution.
By 2010, Su-Kam's Solar PCU had proved itself in the toughest testing ground imaginable: rural Tamil Nadu, under government scrutiny, with data requirements that pushed the company's R&D to its limits. The TEDA project was complete. The technology worked.
Now came the question that would define Su-Kam's next decade: could a solar product engineered for Indian villages compete on the world stage?
The ISA Technovation Award — Bangalore, March 2011
The first answer came from India's own solar industry. In March 2011, the Indian Semiconductor Association awarded Su-Kam the ISA Technovation Award for excellence in the solar energy category. The award specifically recognized the Solar Power Conditioning Unit.
The prize was presented to Kunwer Sachdev by World Chess Champion Vishwanathan Anand. A grandmaster recognizing a grandmaster — one who played with chess pieces, the other who played with photovoltaic cells.
Intersolar Europe — Munich, June 2011
Three months after Bangalore, Su-Kam made its boldest move yet. The company booked a booth at Intersolar Europe in Munich — the world's largest solar exhibition.
The numbers were staggering: 2,280 exhibitors, 165,000 square metres of exhibition space in 15 halls, over 77,000 visitors across three days. German engineering giants, Chinese manufacturing powerhouses, American technology firms.
And among them: Su-Kam Power Systems, from Gurgaon, India.
For an Indian solar company in 2011, this was almost unheard of. India was known as a market for solar — not as a source of solar innovation. But the Solar PCU spoke for itself. Its integrated design was genuinely novel. Its monitoring capabilities were ahead of international competitors. And its price point made it accessible to markets across the developing world.
Intersolar India — Mumbai, December 2011
Six months after Munich, Su-Kam returned to home ground at Intersolar India — held at the Bombay Convention & Exhibition Centre in Mumbai. The industry press described Su-Kam as the "front runner in the field of solar energy in India."
After Munich, Su-Kam wasn't just an Indian solar company anymore — it was an internationally validated one, and Indian buyers, distributors, and institutional customers took notice.
MNRE Channel Partnership — January 2012
The government took notice too. In January 2012, Su-Kam secured official channel partner status with the Ministry of New & Renewable Energy (MNRE) under the Jawaharlal Nehru National Solar Mission.
This was a certified system integrator designation for off-grid solar power plants from 1 to 100 kilowatt-peak. Su-Kam's customers could now claim MNRE subsidies directly — no intermediary needed. The JNNSM had started with only 25 channel partners; Su-Kam's inclusion in this select group confirmed its position as one of India's most trusted solar implementers.
100 Kilowatts at Gates College — 30 Days, Zero Power Cuts
In early 2011, Su-Kam completed one of its most ambitious projects: a 100KW rooftop solar system at Gates College of Engineering in Andhra Pradesh. 400-500 units of power daily. Completed in just 30 days. 60 tons of CO2 saved annually. Engineering students who had suffered constant power cuts now had uninterrupted electricity.
The same technology that started with 300-watt units for Tamil Nadu villages was now powering an entire engineering college.
7,000 Feet in Darjeeling — Where No Solar Had Gone Before
In January 2012, Su-Kam's team installed a 4KW solar plant at Satelite Zoo, Dow Hill, Kurseong — under the North Bengal Forest Department, at over 7,000 feet, in temperatures below 8°C. Panels, batteries, and the Solar PCU were carried by hand through the North Bengal highlands.
The installation was so successful that the Forest Department immediately placed a follow-on order. The PCU born in Tamil Nadu's heat was proving itself in Darjeeling's cold.
From One State to Ninety Countries
The Timeline That Few Indian Companies Can Match:
From a government office in Tamil Nadu to the world's largest solar exhibition in Munich — in four years. That is the speed at which Su-Kam moved when Kunwer Sachdev decided that India's solar future couldn't wait.
