Flexible solar array with structural photovoltaic assembly

A flexible high-power solar array is described that combines the Photovoltaic Assembly (PVA - the solar cell blanket) with a deployable boom structure into a unified integrated laminated assembly - a Structural PVA. The deployable structural substrate provides effective shielding to thin, high efficiency solar cells while the PVA enhances the structural capability of the array wing. Design and analysis results are presented for photovoltaic performance, structural stiffness and strength under critical loads, and detailed mass properties. The results indicate the potential for >300W/kg at the array level including stowage and deployment structure and mechanisms, while meeting typical stowed and deployed requirements. The shielding approach with flexible composite structure backside and integrated coverglass front-side uses techniques that show robustness in a variety of space environments, including adverse radiation environments and high voltage operation.
