One of the most important features in ETAP is its libraries. ETAP has a big collection of libraries for most of the components, like cables and PVs. Those libraries make putting the parameters easier. The 11-kV cable used in Qatar University was found in the libraries of cables in ETAP. After specifying the library to a cable, all that is left it to add the length of the cable. Then, ETAP will calculate the rest parameters like reactance and resistance on its own. Mysolar PV panel module was not in the libraries of ETAP. However, a new library can be added to ETAP. Therefore, Mysolar was added to ETAP as a new library and had been specified to the PV panels used in the model.
