BHEL Powers India’s Space Leap: Supplies Solar Panels and Battery for Historic ISRO-NASA NISAR Mission

New Delhi: Bharat Heavy Electricals Limited (BHEL), a key PSU under the Ministry of Heavy Industries, has marked a major milestone in India’s space-tech journey by contributing critical hardware to the ISRO-NASA NISAR satellite mission. This joint venture between the Indian and American space agencies is one of the most ambitious Earth observation projects undertaken to date.

Indigenous Hardware for a Global Mission

BHEL’s Electronics Systems Division (ESD) in Bengaluru played a central role in powering the satellite. The unit manufactured three space-grade solar panels—each measuring 4 square meters with a capacity of 1100 watts—built using multi-junction solar cells. In addition, the division supplied a high-performance Li-ion battery of 11 kWh capacity using cylindrical Li-ion cells.

These components are critical to the satellite’s energy ecosystem, ensuring uninterrupted functionality in space. The same ESD facility also supplied 112 Li-ion cells integrated into the Geosynchronous Satellite Launch Vehicle (GSLV), which successfully launched the NISAR satellite into a Sun-synchronous orbit at 747 km altitude.
