My perception has long reached the flipping point where sun-facing roof without any solar installed makes the house look like a house in bad maintenance.
I've long thought of them as a visible signifier of prosperity and cluefulness, but since they've become standard on new build they just fade into the background.
I've not seen solar-over-thatch yet. I wonder if that exists in the Highlands somewhere.
But it's more than that with residential solar: at least in places where with a heavy oversupply in real estate, "massive capital investment" is hardly a matching term. More like a drop in the ocean, given the amount of capital bound in the whole package.
