TDB Backs Dhruva Space Solar Array Project For Space Exploration

TDB Backs Dhruva Space's Solar Array Proj. for Space Exploration

The Technology Development Board (TDB) has sanctioned financial assistance for this space startup, demonstrating its confidence in the project’s potential to drive technological advancements in the space industry after it received financial support for the project “Space Grade Solar Array Fabrication and Test Facility” by Dhruva Space Private Limited, Hyderabad.

The Technology Development Board (TDB) is a statutory body, to promote the development and commercialization of indigenous technology and the adaptation of imported technology for wider application. TDB’s backing for Dhruva Space is part of its initiative to develop and commercialize space-grade solar array fabrication and testing processes for spacecraft applications. The primary objective of this project is to pioneer technological innovations in solar panel manufacturing to meet the rigorous demands of on-orbit usage.

The project entails key innovations, including the adoption of new materials like carbon fiber and resins for substrate-side IP to enhance performance and durability. It also focuses on process innovations in solar cell assembly (SCA) through novel stringing and bonding techniques. Dhruva Space aims to manufacture high-efficiency solar panels using triple-junction GaAs technology, targeting an efficiency of up to 30%. Additionally, a specialized test facility will be developed to ensure compliance and certification of space-grade solar arrays.

Furthermore, the project encompassed of a series of space-qualified processes, including substrate fabrication, precise cell welding, secure cell bonding, integration of electrical harnesses, and comprehensive testing and evaluation. Mechanical tests will cover vibration, shock, and full-panel assessments, while electrical evaluations will utilize a large area pulsed sun simulator for thorough testing. Environmental testing includes thermo-vacuum chamber conditions and acoustic testing, with zero-gravity (Zero G) deployment simulations to assess performance in space environments.

Rajesh Kumar Pathak, Secretary of, the technology development board, expressed enthusiasm about the initiative, stating, “We are excited to support M/s Dhruva Space in their endeavor to develop cutting-edge space-grade solar array technologies. This project perfectly aligns with TDB’s mission to promote indigenous innovation and strengthen India’s capabilities in domestic production, furthering India’s commitment to becoming a global hub for advanced and cost-effective space technologies.”

Sanjay Nekkanti, CEO, of Dhruva Space, said, “One of the crucial product offerings at Dhruva Space is the end-to-end design, engineering, assembly, integration, and testing of spacecraft solar arrays for manned and unmanned space programs. One of our core capabilities has been to supply space power solutions to large satellites as well, and we are thankful to the Technology Development Board, Department of Science & Technology, for enabling us to scale these capabilities where we have seen traction not just in India but also overseas.”
