Hello

I am carrying out the MPPT algorithm for the solar panel array using the BP365 model, I found a file pv\_lookup\_data\_bp365.mat, where the information of this specific module is located, the simulation in plecs works well. My question is how can I obtain the .mat file for another photovoltaic module with other characteristics, for example the BP585 module. I have searched for information, but I have not been successful in my search. Appreciate your help

GreetingsDaniel

PLECS does not include a database of profiles for PV panels. There are several online resources and papers that include procedures to go from datasheet parameters like Voc, Isc, etc. to a equivalent IV curves. Alternatively, the BP585 module datasheet may contain IV data as well, which can be digitized and converted into lookup table data.
