Look into radiative cooling. Basically this, but more practical. Several companies working on it: https://www.skycoolsystems.com/

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.

This looks like it depends on the outside air to cool the coolant. "Radiative" can mean that too, not just IR radiation.
