Solar Power for Flyaway Kits

Solicitation # 54f7d913-3f5e-49dc-a4ec-78196d0f1071

The Air Force Global Strike Command Rapid Capabilities Division is seeking innovative commercial or dual-use technologies to provide reliable solar-generated electrical power directly to mission systems without the use of batteries, generators, or other energy-storage devices. This initiative aims to eliminate the logistical and maintenance burdens associated with traditional power systems for aircraft maintainers using rapidly deployable maintenance kits, such as the Expandable Container System-90. The goal is to identify mature technologies capable of converting photovoltaic energy into stable, conditioned power for direct use during periods of sufficient solar irradiance. The selected prime performer will collaborate with the government to conduct site and load assessments and develop a prototype for demonstration at Barksdale Air Force Base, Louisiana. The scope of work encompasses system design, procurement, installation, integration, and testing to ensure the technology provides continuous power when solar energy is available and maintains a safe, controlled response when it is not. Collaboration Link serves as the program administrator for this Other Transaction Authority program, coordinating administrative and payment processes between the government and the vendor.
