"Big" hail can certainly damage panels https://solartechadvisor.com/solar-panels-hail-damage/ but as noted above it's all about frequency and luck, particularly with extremely localised weather phenomena such as microbursts.
A quick Google and a search on another solar forum of which I'm a user showed that there are people protecting their panels, unfortunately 90% of the protection schemes also cover the panels meaning that the protection has to be placed if a storm is coming and removed afterwards.
A 1/2" mesh chicken-wire cover over the panels should reduce any impact damage without massively impacting production. But I've not found any actual test data on such a solution and you have to ensure that it doesn't sag and yet the supports don't shadow the panels.

Down here in BKK I don't recall seeing hail of any size in 20 years or so, plenty of very heavy rain of course. So, famous last words here, I'm not going to bother.
