Which is more durable to sunlight/weather - PLA, ABS or PETG The backstory: I'm installing a pigeon net in my home. Because of the shape of the opening I'm installing the net in and the material on the sides it's difficult to anchor the net using the normal means but I can print clips that will hold the net in place.

The clips will be outside and will be exposed to the weather and direct sunlight, the weather here is relatively hot (up to 30C) with a lot of sun most of the year and rain in the winter.

I only have PLA, ABS and PETG available, anything else will take too long to arrive.

I don't care about the parts changing color and mostly I don't care about them deforming a little bit - only about breaking.

If the parts have to be replaced after a year I'm ok with it, less then that will be annoying, longer will be better.

So, under those conditions, which of the 3 materials is more durable?
Ok, I tried all 3 materials.

PLA failed after less then one day, I believe it deformed from the constant pressure and fell out (I didn't find the part but I didn't really search for it, there's some tall grass below the window)

ABS lasted about a year, it fell strait down and I found the part, it looks ok if probably deformed by just a few mm so it doesn't pressure fit anymore.

PETG still going strong as I write this
