The solar heating system, aimed at reducing fossil fuel use and promoting a carbon-neutral environment, has been installed at DRDO-DIHAR’s Leh campus in Ladakh. This marks Sun Stellar’s first collaboration with DRDO-DIHAR to deploy solar heating across India’s high-altitude regions, supporting the Indian Army.
Sun Stellar, a notable brand in solar technologies in India, recently joined forces with DRDO-DIHAR Leh Lab to create a solar space heating system using unique technology. A pilot project was set up in December 2023, and an expanded system for the ADM Block followed in December 2024. This system, which heated two rooms accommodating 8-9 soldiers to +20 degrees Celsius nightly, has been running maintenance-free for over a year, replacing traditional diesel boiler heating.
The investment for the Solar Space Heating Project was around 90 Lakhs, with a payback period of under three years. The larger system spans 3000 sqft, with 2650 sqft heated, and is expected to last over 20 years with minimal maintenance. The project primarily aims to support the Indian Army, decrease fossil fuel reliance, and encourage a carbon-neutral environment in high-altitude regions.
Sun Stellar is actively collaborating with DRDO-DIHAR to introduce solar energy-based space and water heating systems in high-altitude areas throughout India, including Himachal Pradesh, Kashmir Valley, Arunachal Pradesh, and Uttarakhand.
Karan Taluja, Founder and Managing Director at Sun Stellar India, expressed gratitude to DRDO-DIHAR Director Mr OP Chaurasiya and Scientist Mr Sarfaraz for their trust in the organization. He credited the successful execution of the project to two years of in-house research and development and the concerted efforts of the R&D, Manufacturing, and Projects Teams, who overcame the challenges of working in subzero temperatures and low oxygen conditions.
