Engineering the sun into clean, useful heat

Founded in 2006 by visionary social entrepreneur Mr. Devang Joshi, Rudra Solar Energy Private Limited was built on one conviction — that decentralised solar-thermal technology can serve society while protecting the planet. Today we are one of India's most reputed and trusted solar-thermal brands and Original Equipment Manufacturers (OEM), engineering clean, useful heat for everyone from the smallholder farmer to the largest corporate.

Research and development at our core

We are engineers first. Continuously engaged in research and product improvisation, we run an in-house, high-tech automated test facility for solar-thermal equipment — where every design is measured, refined and proven before it ever reaches the field. That work is strengthened by active associations with leading state and central universities and a network of research scholars, keeping our engineering at the frontier of solar-thermal science.

Patented, proprietary engineering

Our systems are born in our own laboratories, not assembled from off-the-shelf parts. Backed by patented, proprietary designs, every Rudra solar-thermal system reflects years of original engineering — the reason our quality, efficiency and durability are so difficult to match.

A complete solar-thermal range

Solar cookers, solar dryers, solar ovens and solar desalination systems — plus a wide range of specially developed products and applications, purpose-built for the full spectrum of users, from the bottom of the pyramid to major corporates and institutions.

Application engineering that solves real problems

Across our journey we have focused deeply on application engineering — studying how solar heat is genuinely used and translating that insight into practical, field-ready products. That discipline has produced a versatile, dependable product range now trusted by lakhs of customers across India, powering a cleaner and greener future.
