I wanted to ask if SAM has a built-in self-sufficiency metric, and if yes whether it is implemented in PySAM (preferably PVWatts for both). I searched documentation as well as the forum and found no similar metric or how one could leverage already existing outputs to calculate this. I realize that a rough estimate could be found by dividing energy produced by PV/energy required by facility, but if the system does not have an installed battery and the electricity supply and demand profile curves don't match, then that rough estimate becomes highly inaccurate.
NB. Self sufficiency in this case is defined as: "how much of the consumed energy, came from the photovoltaic system."
