I would like to see Solar Energy Level modifier being added to the Planetary System Designer.
Given that the Planetary System in this game is highly customizable, and that one can create different type of star for it or make a System with different Size / Distance scale from the stock Planetary System, We should be able to adjust on how much energy Solar Panel can generate to better match the Star type or the Size / Distance Scale of the custom Planetary System which may be different from the Stock Juno System’s 1:5 size and 1:10 distance scale.
for example, If the Planetary System has a White or Blue main sequence star we could make the star generate more energy for Solar Panel, while Orange, Red and Brown Dwarf will generate less energy, etc.
1:10 scale = KSP scale
