Yeah it's a misconception, it's the Dyson swarm that's high maintenance

I doubt it. A structure like that would be an enourmous engineering project pummeled by solar radiation on the inside and space debris on the outside.

I guess it would depend on the temperature resistance and how the power is transmitted. Even solar panels wear out, and the collection surfaces of a dyson sphere would be a lot higher temp. But with something that scale, I'd imagine it would be a ton of maintenance work even if was a tiny amount per area.

I mean wouldn't you still have to maintain the electrics of a sun sized surface? I guess you could use its own power for maintenance robots...
