NOVELTY - The panel has a concentrator solar blanket assembly (100) defining a bottom surface of the panel. The blanket assembly comprises a flexible solar cell substrate supporting an array of crystalline photovoltaic solar cells. A flexible refractive lens assembly defines a top surface of the panel. The refractive lens assembly comprises flexible lenses (101) supported by supportive frames, where the refractive lens assembly is offset from the blanket assembly by an elastic structural system such that optimal concentration of solar radiation upon the array of solar cells is achieved.    USE - Rollable and accordian foldable refractive concentrator space deployable blanket-type solar array panel for photovoltaic energy conversion systems spacecraft/satellite application.    ADVANTAGE - The panel accommodates standard state-of-the-art multi-junction crystalline space solar cell technologies and advanced next-generation ultra-high efficiency photovoltaics, and significantly reduces the cost and mass of flexible blanket space solar arrays by replacing a significant portion of the very expensive solar cells with a simple and space-proven refractive concentrating lens element, and dramatically reduces stowed volume by allowing for a compact rolled or accordion folded flat package stowed configuration. The panel is unique, light in weight, and efficient in design to be lead for outstanding performance metrics in areal power density, stowed power density and specific power, thus protecting against electrical discharge, micrometeoroid impacts and radiation degradation, and hence providing arc-free high voltage operation as the solar cell strings/circuits are significantly separated from one another, and can be more easily fully encapsulated from LEO plasma or GEO charging environments.    DETAILED DESCRIPTION - The supportive frame is a sliding frame.
