IceBear was competing directly with ever cheaper PV.

It's a tech for time shifting cheap overnight energy to the expensive daytime.

Installing PV gives you cheap power directly and correlates with air-con demand.

Nope.

You still need aircon at 7pm after the sun begins to set and while solar is losing power.

Cooler temperatures aren't until 10pm or so, hours after sunset.
