Standards are also reviewed periodically; a standard alongwith amendments is reaffirmed when such review indicates that no changes are needed; if the review indicates that changes are needed, it is taken up for revision.
Reference values of ambient temperature, in-plane irradiance and spectral distribution, specified for power rating of PV arrays. For measurements in natural suniigtit, wtien the ic solar beam is not at or near normal incidence, it is recommended to use a reference module of the same type and size as those being tested or a multi-cell pacltage consisting of a calibrated cell surrounded by other ceils dummy or real in such a way that frame, encapsulation system, shape, size and spacing are the same as in the modules being tested.
