Space Solar Solutions

Rocket Lab’s Space Solar Solutions provide complete power solutions for all spacecraft, combining high-efficiency and radiation-hardened solar cells with modular and customizable solar panel arrays. These solutions are designed to power spacecraft for any orbital, Lunar, and interplanetary mission. The offering includes both solar cells/Cell Interconnected Components (CICs) and solar panels/substrates. The solar cells and CICs are described as the highest efficiency commercially available products, achieving efficiencies up to 34% and delivering over 4MW of power for flight missions. They come in standard cell areas up to 81.5 cm² with custom sizes available. Flight-proven technologies include space-qualified triple-junction (ZTJ, ZTJ+ & ZTJ-Ω), quad-junction (Z4J & Z4J+) and five-junction (IMM-β) solar cell technologies. The space-qualified solar panel arrays are designed to meet rigorous demands, offering customizable, modular solutions for diverse power needs. Both rigid and flexible build-to-spec solar panels are provided, fully tested and ready for integration. Comprehensive offerings include rigid space photovoltaic solar panel assemblies (PVA), solar panel substrates, solar power modules (SPM), and flexible PVA panels. These solutions support CubeSats, SmallSats, and large satellite constellations, with lightweight and durable panel materials for compact spacecraft and automated production lines for high-volume constellation programs. The products are backed by over 25 years of flight heritage.
