Large-scale deployable solar array

A deployable solar array comprising:

• two slit-tube longerons comprising a shape memory material, wherein the slit-tube longeron comprises an elongated tube shaped material with a slit along the length of the slit-tube longeron ;
• a heating element coupled with each of the slit-tube longerons;
• a first solar array sheet having at least two edges, wherein each edge is coupled with one of the slit-tube longerons,
• wherein the deployable solar panel is configured to be stowed in a rolled configuration with the two slit-tube longerons rolled along a longitudinal length of the slit-tube longerons, and wherein the deployable solar array is configured to transition to a deployed configuration when the slit-tube longerons are heated by the heating element.
