Does sun damage a ceramic coating?

Technically, yes. Given enough time, the sun is a factor in the deterioration in all man-made materials, but in a practical sense, no it doesn't.

The base coat of cars has historically been prone to fading, but modern paints are very UV stable in terms of colour, and they are protected by the clear coat which filters out UV. So this isn't really much of a concern over the lifetime of a modern car.

Faded paintwork
Older cars used to be prone to oxidation and fading, which needed to be polished out.

UV radiation can also combine with oxygen and Ozone to cause oxidation, which causes paintwork, and more specifically the clear coat, to become dull and hazy. On modern cars this is far lesser than it used to be, but it still happens, although a little polishing can easily remedy this.

Ceramic is far more resistant to oxidation than a normal paint coating, so the sun is not a concern.

Where the sun is a factor is where it heats up water deposits on your car which can cause hard watermarks, or if it heats up bird mess which is corrosive.  We recommend removing bird mess as quickly as you can, and a spot remover can be used to dissolve mineral deposits.
