BHEL Powers ISRO’s CMS-03 with Indigenous Solar Panels and Li-Ion Battery

The Indian Space Research Organisation (ISRO) successfully launched its 4,410 kg communication satellite CMS-03 aboard the LVM3-M5 rocket on November 2. A key highlight of the mission was the use of indigenously developed solar panels and a lithium-ion battery supplied by Bharat Heavy Electricals Limited (BHEL).

BHEL’s Electronics Systems Division in Bengaluru manufactured three space-grade solar panels, each measuring approximately 5.32 square metres and capable of generating 1.2 kW of power. The company also delivered an 11 kWh lithium-ion battery for the satellite, along with 110 li-ion cells for the launch vehicle.

According to officials, the components underwent rigorous space qualification, marking another milestone in India’s efforts to reduce reliance on imported satellite subsystems. The collaboration underscores the growing technological capability of public sector enterprises to support India’s space missions.

CMS-03 is designed to provide communication services across India and surrounding maritime regions. Its deployment is expected to strengthen connectivity for defence, disaster management, remote communications, and national infrastructure services.

The mission highlights the increasing synergy between ISRO and domestic manufacturing entities, advancing the country’s goal of self-reliance in strategic space technologies.
