100% Solar Powered House in Punjab — No Connection to Mains
Punjab
In parts of Punjab where grid power was unreliable or simply absent, one household went fully solar with Su-Kam's Solar DC home lighting system — no connection to the mains at all. Everything in the home ran on solar.
The setup was built around Su-Kam's Solar DC approach: a rooftop panel feeds a DC home-lighting unit with a built-in charge controller, powering DC lights, a DC fan, a TV and a USB mobile-charging point directly. Because the power never has to be converted from DC to AC, almost no energy is wasted along the way.
For homes beyond the reach of the grid, this design was transformative — affordable, efficient and simple enough to run an entire household on sunlight. Su-Kam positioned its Solar DC System (including the popular DC 120 model) as a way to bring light to places where, in the company's words, no home had ever seen light.
It was part of Kunwer Sachdev's bigger bet: that solar wasn't just for demonstrations or subsidy schemes, but a practical, everyday power source for ordinary Indian homes — even the ones the grid never reached.
