Outdoor environmental variability leads to the need of artificial illumination systems for PV module characterisation. The two main solar simulator types in use for this purpose, steady state and flash simulators, each have advantages and disadvantages regarding practicality of use and breadth of applicability. To combine the advantages of both types and eliminate the disadvantages, an LED-based solar simulator has been developed, capable of producing light in variable flash speeds and pulse shapes or as a continuous light for long-term measurements. The system features full control of all light sources allowing variable intensity and spectral distribution during measurements. The paper gives a technical description of the measurement system. The results of the initial qualification tests and initial measurements are included.
