I've not built one, but there's quite the cottage industry on WispTalk. Sizing required panels, sufficient batteries, charger (with generator option), DC converters & injectors for radios (there's an annoying mix of voltage requirements, but you lose far too much doing DC to AC and back to DC to use the shipped PoE injectors). Plus remote management.

Ubiquiti kinda, sorta sell a kit.

But I am curious as to what extent solar power (how many watts?) can
be used nowadays for heavier duty backhaul radios, and what forms of
long term battery storage now exist?

Most UPSes sold in stores are designed for a high load, for a short
time, where aiming for 2-3 days of backup power would be better in
this case.
