Solar panels have a limited lifespan, decrease in efficiency over time, and also get ruined when things like hail happens. This doesn't mean PVs are a bad idea, but it's not accurate to say they have little to no maintenance.

20 year solar panels just loose 5-10% capacity and degradation slows over time the reason most people replace them today is 20 year old panels were 200w where as today panels are 5-600w.

'Replace every 15-20 years' is not maintenance. Neither is replacement in the case of catastrophic weather events that'll have you replacing all your windows as well. The only 'maintenance' solar panels benefit from (which is still entirely optional) is occasional cleaning.

Aside from the hail, none of those are maintenance requirements. I've done 0 maintenance on my panels over their lifespan.

Sure but how do these artificial leaves fare when analyzed with the same criteria? Presumably worse, given that solar panels are (roughly speaking) nothing more than a few sheets of material laminated between glass panels.

Artificial leaf is an alternative term for extra complicated solar panel.
