Cleaning them is a lot less important with the new generations of solar panels, but if they wanted to they could always use a hose or a brush or whatever. I’ve managed a couple of smaller solar farms where they don’t get touched at all unless you need to pick off a dead seagull or something and the yield is pretty constant.
Most of the sand and dust will also be blown away by the wind.
I have a dumb question - on windy days do the cells get covered in desert dust and sand? Is there a way to clean them off if that happens?

That's definitely a thing, but the buildup isn't too fast so it just becomes a regular maintenance item.
