To help relieve some of the lowpop issues, I personally think solars should be set up roundstart, at least for the specifically lowpop maps, so the station always has some power.
- It doesn't make sense IC that the lowest effort and lowest risk source of power wouldn't already be set up at the start of the shift other than Nanotrasen being that fucking cheap. Usually it's just placing some wires then pushing some buttons on a console. NT being unable to do that when building the station or in previous station shifts just feels absurd.
- It doesn't make much of a difference OOC/meta if solars start already set up because they don't make enough power to invalidate the other engines. Bored engis/MoMMIs will set up solars at some point anyways even if the engine of choice is still making enough power. If more people start using/building equipment on the station then there will be a need for a real engine setup but otherwise there shouldn't be an issue on lowpop.

Having tracking for solars automatically set up at roundstart could be a difficult code issue (or maybe not, it could just be as simple as calling a verb/proc at roundstart) but having solars wired at roundstart is a simple mapping issue that could be done in 5 minutes. Even non-tracking solars should be able to keep the airlocks working on most of the station.
