Solar energy is the furthermost imperative resource of energy now a day. It is difficult to test different PV system equipment for particular weather condition because of weather condition is constantly change on earth with real PV panel or array. Also, it is also complicated to maintain weather condition for testing purpose. So, any equipment is required to test PV system equipment against above-mentioned difficulties. A PV emulator is a DC-DC converter, which can duplicate the preferred output behavior unrelatedly of the weather conditions to analyze and tests diverse PV systems equipment for the different environmental condition. In this paper lambert W algorithm-based PV array emulator is presented. It is tested against linear and non-linear load and compares its results with conventional PV array emulator which behavior are similar to the real PV array. And it also gives PV emulator to connect with maximum power point tracking (MPPT) to test MPPT on PV emulator at different techniques. Also, it is tested with MPPT and compare with the Lambert W algorithm.
