They would do harm if it was left in the sun 24/7.
UV light is well known to be the most damaging part of the light spectrum, fading colours, weakening plastics, etc much faster the visible light or IR.
Flying for a hour, 2 hours, etc a few times a week is fine.
If you were flying all day for a living in a harsh sun, there might be some fading within a year, some cracking might be visible after, 5, 10 years ?
Not something most commercial or hobbyists will be concerned about.

I read somewhere that UV rays do interfere with WIFI signal.
Another matter that bugs me is when I flying the drone, a warning pops up saying aircraft interference. In fact I checked the area and there were no aircraft around. Does this warning have to say that there are strong electromagnetic and UV interferences especially near power lines which carry 33,000 volts?

Solar flaring can interfere perhaps if strong enough, @sar104 may have posted something on another thread recently touching on this subject.
(Was a thread to do with possible GPS interference.)
The time approaching (solar minimal) according to the article is a quiet time for such activity though, perhaps many years, though it does cycle a little during each period, depending on factors stated in the article.
"This solar minimum ends solar cycle 24. Early predictions estimated the peak of solar cycle 25 will occur in July 2025"
Interesting topic.
The overhead powerline interference is purely electromagnetic I'm fairly sure.

UV radiation has no effect on wifi - its frequency is far too high (> 10¹⁴ Hz)
Aircraft interference refers to interference on the radio link between the RC and the aircraft from nearby transmissions in the GHz range.
Power lines don't interfere with the radio link, their frequency is far to low (50 or 60 Hz).

The magnetic field is weak and alternating - you would need to be really close to see any effect.
The aircraft interference warning appears when I am close to a Radar at the Airport and we have another large Radar on the highest point on the island and sometimes the Radar signal interrupts minimally on the RC and drone. Thanks for the information.
I would be less concerned about the UV damaging your drone than the heat damaging the batteries if they are out in the sun and heat.
