Sun Stellar join hands with DRDO-DIHAR Lab to build Solar space Heating project to High-Altitude of Ladakh

• The solar heating system is installed for solar energy-based indoor space heating in the campus of the DRDO – Defence Institute of High Altitude Research in Leh District of Ladakh U.T

• Project aimed at serving the Indian Army, reducing fossil fuel dependence, and fostering a carbon-neutral ecosystem, marks the beginning of Sun Stellar’s collaboration with DRDO – DIHAR to implement solar energy-based heating systems in high-altitude regions across India.

Sun Stellar, one of India’s leading brands in Solar Technologies recently collaborated with DRDO – DIHAR Leh – Lab to design a Sustainable Solar Space Heating System using patented technology. A pilot project was installed in December 2023, followed by a larger, upgraded system for the ADM Block in December 2024. This system provided space heating for two rooms accommodating 8-9 soldiers, maintaining an ambient temperature of +20 degrees Celsius from 6:00 PM till 6:00 AM. Running seamlessly for over a year with zero maintenance, the system replaced conventional diesel boiler heating in the area. 

The initial investment for the Solar Space Heating Project is approximately 90 Lakhs, with a payback period of less than 3 years.  This larger system covers an area of 3000 sqft, with 2650 sqft requiring heating with a lifespan exceeding 20 years with low maintenance requirements.  The project’s primary motivation is to serve the Indian Army, reduce dependence on fossil fuels, and promote a carbon-neutral ecosystem in high-altitude areas.

Sun Stellar is actively working with DRDO – DIHAR to implement solar energy-based space and water heating systems in high-altitude regions across India, including Himachal Pradesh, Kashmir Valley, Arunachal Pradesh, and Uttarakhand. 

“We thank DRDO – DIHAR Director Mr OP Chaurasiya, Leh – Ladakh (India) and Scientist Mr Sarfaraz for Showing trust in our organisation and allowing us to prove our dedication towards a Carbon Neutral Ladakh. After doing in-house R&D for 2 years, we executed this project. We give all the credit to our R&D Team, Manufacturing Team and Projects Team who worked hand in hand to meet the deadlines of the project and commissioned the project in subzero and low oxygen working conditions,” said Karan Taluja, Founder and Managing Director at Sun Stellar India
