Rocket Lab Corporation has announced the introduction of advanced silicon solar arrays designed to power gigawatt-scale space-based data centers. These arrays are intended to address the power constraints, land-intensive nature, and water consumption of terrestrial data centers by taking advantage of the abundant space, cold environment, and limitless solar energy available in orbit. The silicon solar arrays are cost-effective, lightweight, and modular, enabling scalable power generation to support the growing demand for data processing and storage beyond Earth's atmosphere.

Why it matters

The satellite industry is projected to grow significantly by 2035, and space-based data centers are on the horizon. However, the current reliance on critical minerals like gallium arsenide and germanium for solar cells poses supply chain risks. Rocket Lab's introduction of silicon-based solar arrays reduces this dependence and future-proofs the space power supply, enabling the ambitious and revolutionary space capabilities of the future, including mega constellations and data centers on orbit.

The details

Rocket Lab's silicon solar arrays feature radiation-hardened solar cell modules that are flexible and lightweight, allowing for various stowage and deployment methods. As a fully vertically integrated space power supplier, Rocket Lab can streamline production and deliver cost efficiencies by offering solar cells, assemblies, modules, panel substrates, and complete solar panels and array wings. The company has also developed a hybrid solar array solution that combines high-efficiency and silicon solar cells, enabling adaptable and scalable solutions for any mission.

  • Rocket Lab announced a $23.9 million CHIPS award in October 2025 to expand semiconductor production capabilities in Albuquerque, New Mexico.
  • Rocket Lab introduced the advanced silicon solar arrays on February 26, 2026.
