The Redwire HiPASS solar array is a high- power rigid solar array solution for smallsat applications.

The HiPASS solution powers missions with a tailored solar array system that supports ESPA- class electric propulsion missions. The HiPASS solar array uses metallic tape spring hinges to fabricate a solution that is robust to system level tolerance stack-up risks. The SADA-compatible HiPASS is engineered with low-cost graphite panels that are designed to minimize manufacturing risk and complexity.

The HiPASS Rigid Solar Array is a mature technology: 10 flight HiPASS wings (for use on multiple U.S. Government missions) are planned for delivery in 2022.

HiPASS Solar Arrays are export controlled through an ECCN (Export Control Classification Number) issued by the United States Department of Commerce. Export shipment requires successful application for an export license (under ECCN7A004 for HiPASS Solar Arrays).
