These solar panels deliver 800W peak. Water kettles, hair dryers, flat irons, space heaters all need more power. If the wiring is good enough for these appliances, it should be good enough for such a solar panel.
People dont get the problem, with a plug in solar panel you can have something behind a fuse draw more current than what the fuse sees. If your panel provides 800w and you have other appliences in the same circuit behind the fuse that pull high current they can pull nearly the max of your fuse through the fuse and all the current of your solar panel which would be more than the wiring can tolerate without the fuse blowing. That doesnt take into account that that the wiring could not even be capable of handling max current of your fuse as others here pointed out with shitty wiring that has been done in old houses where at some point someone just changed a fuse without really updating the cables in the wall.
My grandpas house in france had so shitty wiring that i would have never trusted it to be safe. Flat cable with broken isolation and no protective earth and a horrendus subpanel.
Yeah but there are a lot of shitty old buildings with shitty old wiring here.
Using the hot water tap in my kitchen nearly set my building on fire last year when the mini boiler under the sink shorted out after having melted all the insulation around the wires leading to it. That oily fishy smell of wires burning still haunts me.

Just do what the Americans do, require it to be on its own circuit. Put in a 5a fuse and Bob’s your uncle.
It is not an actual problem.
It’s not that simple.
This is what The Institution of Engineering and Technology has to say:
