a) solar simulator class

rating method based on simulator performance for spectral irradiance match, non-uniformity and temporal simulator instability

NOTE Three classes of solar simulators are defined, class A, B and C, with A being the best

b) pulse type solar simulator

flashed light source consisting of one or more long-arc xenon lamps capable of irradiating large areas uniformly with little heat input to the PV cell or module being tested

c) steady-state type solar simulator

continuous light source frequently employing filtered xenon, dichroic filtered tungsten or modified mercury vapour with tungsten electrodes as the light source
