Only one of them needs to be up at a time. By choosing the antipode, by definition one of them will be in sun when the other is not (weather notwithstanding). The equinox would be the hardest day to deal with because they would both be at low energy at sunrise/sunset.
So yes, you're right, a third server would probably make it work almost 100% of the time.
Ah, I see what you mean. If they are antipodes, then dusk and dawn will happen together every day. This is a good point. I was thinking there would be more overlap on the other days, but you're right, there wouldn't be.
