Solar plus battery near the equator can be sized for 24/7 power with relative ease.

But no one would do that, because we don't need power at the same rate all the time. Near the equator, where most people on the planet live, our need for energy is correlated with when the sun is shining and air con is running and people are awake.

This is why solar is better even at the mythical "baseload" than nuclear is.

Nope.

In fact, a minority of people live near the equator... for good reason:

Also, the base load most of us are talking about isn't created by people for the most part... it's created by industry, without which life on the equator or anywhere else would be rather primitive.

In any case, the equator is going to become unlivable in the next few decades to the point where populations in equatorial areas will drop drastically.

Do you have any data on power consumption near the equator, or where does this assertion come from?

Anecdotally, it doesn't ring true to me from my time in Thailand and Malaysia, where inefficient air con would be left on in poorly insulated houses overnight to help people sleep. I couldn't find any graphs like you can trivially find for power grids in the west.

But I did find this article[1] which indicates the record power consumption occurred at 9:35pm, beating the previous record which occurred at 10:28pm a few years prior, and both of these are times where it's all going to be coming from batteries.

But this isn't necessarily representative. Even if your reference is a book I'd be happy to purchase it, I find solar penetration in developing countries particularly interesting.

You are hand waving the complexity, cost, feasibility and trade-offs of doing this.
