how to make things only run when sun is up

Switch to a pure solar power factorio, with no other source of power?

[Koub]

Power them only with solar panels.
Or power them with another energy source, and add a power switch that turns off based on the condition that an accumulator not empty. And link this accumulator to a set of 6 solar panels and 1 radar out of your main electric grid. As soon as the solar panels will provide less than what the radar consumes, the accu will discharge gradually, and as soon as it is empty, the power switch will turn off, cutting your factory's power supply.

The single lamp is exemplary for what ever you want to run at daytime you can replace it with a switch as well. By increasing/reducing the lamp array on the left you can define the minimal light that defines day.

Though for steam engines I'd switch the offshore pumps directly. To turn off something else a power switch is fine. If you don't use an SR-Latch everything flickers around the switching point
