Abstract
Dark I-V tests are sometimes used to determine the condition of spacecraft solar cell arrays. This is particularly true in cases where the array is mounted on the spacecraft such that some or all of the array cannot be illuminated. This paper shows that these tests are unable to find even significant damage to arrays and, for the most part, serve only as continuity checks. This is shown to be the case from both theory and experiment
