The Solar PV Emulator is a programmable power supply designed to emulate solar panels. With fast transient response, the emulator responds to change in load conditions and maintains the output on IV characteristics of the user defined configuration of solar panel for a user selected ambient condition. A user can input the desired specifications of a Solar PV Panel such as Voc, Isc, Temperature Coefficient, Irradiation, Temperature, Area and Series Resistance to simulate the characteristics of a solar PV panel and utilise the actual electrical output. A user can simulate partial shading conditions up to four peaks using the system software and utilise the actual electrical output.
