Solar panel, mounting question.

[Whodat]

Hi - I have Mini stonewold tiles (https://redland.co.uk/products/slate-range/mini-stonewold). They are laid with a 15cm headlap.

It is more sensible to get a long roof hook such as the renusol UK flexible, or cut into the tiles? I'm guessing the former, even though it makes for a longer moment arm...?

I would also recommend using a plank to walk along whilst working on that type of tile to avoid breaking any
