Abstract
A concentrating solar array consisting of a roll of reflective film which is stretched between tension wires strung between a pair of wire stays. There is a roll of film and a take up roll such that the film can be unrolled from the storage roll and pulled toward the take-up roll to replace degraded film. A pair of extension arms holds a solar cell at a fixed position relative to the solar concentrator film surface to receive concentrated sunlight. The roll of reflective film ensures the life requirements of the solar concentrator can be met in space, by replacing exposed concentrator film as it degrades.
