Its not the right long term solution tho, tiny roof tiles as solar panels have so many problems:

- Magnitude higher number of interconnections which impacts reliability and efficiency

- Uniform roof tile style

- Requires entire roof rebuild which is always more expensive than retrofit of panels on top

- Complex installation resulting in less installers available overall for the market

- Crossing of trades between roofing & electrical

A slightly better solution would have been to make the big traditional solar panels your actual roof panels but really retrofitting them on top of panels solves most of those issues above.
