I think a power system would actually work really well. Starbound is the perfect game for that mechanic...
That would be glorious. It would obviously have to be a very late upgrade to be able to power your ship with solar panels, but could you imagine never having to use coal as a source of fuel again?
This would be so fun, some people say that they don't want to have to have power to use stuff, but it think this could be used in addition to generators, or something else that can give you power at night later in the game, It would b e allot more realistic and in my opinion, pretty fun, i love working with electricity, and wiring, and everything, and that is why one of my favorite modpacks for MC is tekkit, and in the future if anyone figures out how to make adventure maps, they could make it so only certain areas are accessible during certain times.
With this my house would be open during the day but at night all the doors would close and be unable to open because there is no power. I like it!
