This looks like it depends on the outside air to cool the coolant. "Radiative" can mean that too, not just IR radiation.
I don't quite believe this.
Is it really better than just using solar panels to run a heat pump?

A heat pump is a “ vapor-compression based cooling system” so that tech is an addition-to not an instead-of.
Whether it’s better probably depends on how expensive the additional efficiency is in practice.
> SkyCool’s Panels save 2x – 3x as much energy as a solar panel generates given the same area.
So if you’re area constrained maybe.
