Hi @RadwaEzzat ,
Sorry that I saw this topic too late.
If you hover over any Ladybug component’s input or output, you will get a description of it. Here is an example for the systemSize_ input:
systemSize: DC (Direct current) power rating of the photovoltaic array (on one of your facade faces) in kilowatts (kW) at standard test conditions (STC).
I made a small example which would make it more understandable what each of the inputs you marked does.
With exception of minimalSpacingPeriod_. I would not change that input, and let the component itself calculate it internally.
You can play around with inputs in the .gh file below just to see how they are affecting the creation of PV_SWHsurface output.
I hope this helps.
