Depends how you sliced it.

If every house had solar panels, there's going to be a rolling requirement for on going maintenance.

Let's say, for argument sake, solar panels and inverts are approximately as reliable and long lasting as air conditioners, we'll still need a whole new fairly large industry.

Seems doable, but we'd need to deal with recycling all the parts, still doable, but there's nothing self sufficient about any of that.

Indeed, but that is why I said “decades”.

I am responsible for maintaining eight 150 Ah 120v dc battery banks. The sites also have diesel generators so the batteries really only get used for the 10 seconds it take the diesel to start, maybe 4 or 5 times a year. The batteries are indoors. So far cells start to go after 5-7 years and then I have to replace the whole bank.

Even 1 decade is optimistic life from current technology batteries that I am being sold from industrial battery sales channels.

be careful claiming that solar PV systems last decades. Many recent builds have components that fail including the panels, junction boxes, the panel-to-panel connectors and the inverters themselves.

Solar isn't as reliable as the solar industry would have you believe. Worst part, a single component failure often takes large sections of the system offline. With domestic systems, that's the entire system.

I’ve heard of issues with contactors failing in cold temperatures and dust or dirt (it is the desert, sand gets everywhere) causing fibre connections to stop working, ruin fans, cause overheating, outages, millions of dollars lost.
