PV Emulator is a programmable power supply designed to mimic the characteristics of Solar Panels. With fast transient response, the emulator responds to change in load conditions and maintains the output on IV characteristics of the panels defined by user for a given ambient condition.

It is a flexible instrument designed to emulate the output of solar panels, with adjustable parameters such as Voc, Isc, shading, coefficient of temperature etc. The PV Emulator uses an internal algorithm to adjust Voc (Open circuit voltage) and Isc (short-circuit current) so as to match the solar panel selected by the user based on user defined parameters such as Irradiation, temperature, Voc, Isc, temperature coefficient etc. The Emulator makes sure the response matches that of the actual panel under all the load conditions within range. The user is presented with a complete set of information with tables and plots on user application.

The software of PV Emulator is based on Labview. User is able to see the response of Solar PV Panel as per his/her own set of users defined parameters. User defined parameters involve open circuit voltage, short circuit current, temperature coefficient, complete shading, partial shading (up to 4 peaks), series resistance, area of panel, diode quality factor and operating temperature.
