My idea is to be able to sleep in your pod until morning, it would not be a requirement to sleep but just so you can skip the night so that your base can charge up from solar panels.
Sure wind turbines can power your base both day and night but it is occasional, this way you don't ave to wait until morning when you can sleep and only wait afew seconds.
In multiplayer, when one person sleeps and the other does not, it would still turn to morning.
