Panel mass (kg/m^2)2

Panel efficiency0.3
I don't model PMAD electricity losses, so if you want to include them reduce this value accordingly.

5
PMAD mass (kg/kW max load)5System mass (kg/m^2)3.05
I have no idea what a reasonabe value is so I set it so that it's about 1/3 of the total mass. If anyone has better data let me know.

SpaceX claims the cost will reach <$144/kg, but I think that will take a while.
