Gurgaon-based ZunRoof operates in two growing business segments— solar energy and IoT devices for homes. While there are startups working to bring togetjer solar energy and IoT for commercial purposes, the residential market has very few players due to the unit economics in play. “Home systems, while small, are many in number. With software innovation, the experience and cost savings that customers can get are significant. With states offering subsidies, this becomes even more attractive,” says Pranesh Chaudhary, founder and CEO, ZunRoof.
