The bit I haven't understood is why a roofing company hasn't come
up with a solar panel roof? Or have they? I can't see the case for
drilling holes to install panels on top of roof tiles/slates.

They shouldn't drill holes.
They have brackets that go under the tiles/slates and then attach to
channels that hold the panels.


True for concrete interlocking tiles.

Plain tiles and slatres have to be cut.
Then they have to fit lead soakers or expensive gadgets that replace the
tiles.

The hole drilling virtually guarantees a leak.
