It is nicer looking. No idea is power generation is better or worse than traditional panels. It would be lighter than clay tiles. But probably heavier than metal formed tiles. No idea if the connection between tiles would be a problem in the future.

Tesla one is flat. This one is curved. Typical Asian style house roof tiles.

He is saying the solar panels would degrade and not efficient and need to be replaced in XX amount of years.

Same idea. The degraded paint can be left as it is. Just that it is not aesthetically pleasing. Same as the panels that is not depleting until it is not functional. It does not serve its purpose anymore and is no longer aesthetically pleasing.

Many years ago got people said something about it. But so far not exists yet.
