What kind of change does this PR introduce?
(Bug fix, feature, docs update, ...)
default update for 'PV tilt'.
core/pv.jla change was made to make sure we are using the same assumptions as PVWatts guidelines, the defaulttiltangle for a fixed array should be 20 degrees, irrespective of it being a rooftop(0)or ground-mounted (open-rack)(1)system. By default thetiltwill be set to 20 degrees for fixed ground-mount and rooftop, and 0 degrees for axis-tracking (array_type = (2), (3), or (4))What is the current behavior?
(You can also link to an open issue here)
The current default
PV tilt anglefor a rooftop is set to 10 degrees and for fixed ground-mount to 20 degrees.ElectricStorageInputs input soc_min_fraction always applies during outages
What is the new behavior (if this is a feature change)?
The new behavior sets the tilt angle for fixed PV rooftop and ground-mount to 20 degrees and for axis-tracking to 0 degrees. This aligns it with the pvwatts defaults.
Added soc_min_applies_during_outages boolean field to ElectricStorageInputs (defaults to false)
Does this PR introduce a breaking change?
(What changes might users need to make in their application due to this PR?)
Specify a
PV tilt angleif they may need to use a lower tilt angle for their fixed arrays than the new default of 20 due to hardware cost, wind, or other consideration considerationSpecify soc_min_applies_during_outages in inputs if you would like it to be true
