How do they deal with the cost of storage for anything non trivial completely eclipsing any savings?

Well it doesn't eclipse savings, you can still get about 12% annual ROI in developing countries with a battery.

And many will make do without a battery, just relying on power during the day.

I mean it's several hundred fold more expensive I'd call that "eclipse" but maybe you have a higher threshold for that word?

I mean I guess that's an option if you don't want these places to advance in quality of life or produce much of anything.

		It increases costs of a solar system to about 1.5-2.2x (so an extra 50-120%), not several hundred fold. The hybrid inverter is slightly more expensive than a normal inverter, then you add the 4-16 kWh battery which is pretty cheap nowadays.
