Thanks for all the suggestions, guys. I've had to redesign my power satellite slightly, so I can't try it right now, but I will report back once it is done. Currently I'm planning on catching an approaching Eve transfer window for maximum efficiency. To get the most out of it, would I want to intercept Eve on a retrograde orbit? In my mind that might help me go somewhat lower than a "normal" Eve orbit. Well it barely applies in that I am gaining a slight boost from Kerbin's orbital velocity, but really you're right.

I know the Oberth effect makes it easier to get out of Kerbin's SoI, but if I want to get close to the sun, would it be easier to burn on Kerbin's retrograde instead of prograde? Or would that not make any significant difference? Also, is there an easier way to get to the sun once out of Kerbin's SoI besides burning retrograde? Like would it be more efficient to swing by Eve and maybe Moho from there? I'm trying to get a solar power satellite into low orbit with Interstellar Mod parts.
