Abstract:
A method of detecting a discontinuity in: a solar array (10) comprising: locating a detecting device (200) in one or more working positions (56) along the solar array: inducing a signal (80) by applying a plurality of flashes of light to a solar module in the solar array: measuring (64) the signal at two different locations along the solar array; comparing the signals measured at two different locations to each other, and outputting (62) a result of the comparing step.
