And this is probably the core issue. Solar Roof was trying to be a roofing product, an energy product, and a design product all at once

That doesn't mean it's a bad idea, Building-Integrated Photovoltaics are its own market of products. But you have many much cheaper options there, at least in Europe. For example https://solroof.eu/en/discover-solroof/what-is-solroof/ or https://metsolar.eu/products/bipv-roof/

Do you have any pointers like that solroof that don't bother trying to be inactive anymore?

My benchmark there is a ventilated attic with insulation between attic and house, using traditional glass roof structure filled with frameless glass-glass panels instead of human-below rated laminated safety glass.

Like, it can't be that hard to do better when you're not trying to be substantially fancier than a classic gable roof, it's just that the panels need to not be shear-loaded much, and the structure doesn't have to be so pretty from underneath as traditional glass roofs.
