Extra solar panels don't hurt, they are light and small, it is easy to deliver to orbit.
The absence of any information about how much of each stuff must be there and in which shape it should be made - that hurts. Because it is not even hard - it is impossible to guess. Thus i hope you can answer those questions, so we could establish the picture of space station, which totally without any questions qualifies for this challenge - then i can build it.
Building something in orbit and only after it is done finding out that it doesn't pass, because it has too little amount RCS engines or it's docking area is incorrectly made - that would be so a disaster.
