It's extremely labor intensive and costly to put stuff up on the roof, and problematic in terms of electrical connector, electrical safety, and being proprietary for mounting and roof repair. Big ass PV panels that are 2.0 x 1.0 meter in size (or larger) are so cheap now for photovoltaic ground mounts that the labor and mounting can actually cost more than the panels.

460W panels can be something like $0.25 USD per STC watt in single pallet quantities shipped as LTL freight.

Or at least if you have to use your roof, just put them on boring aluminum rail mounts on roofs which are a much more known factor for roofing repair and labor.

without having looked into the tesla roof tiles like at all (so stop reading here if you want any sort of informed discussion), are these things like placed individually and wired together individually? does every tile get a microinverter or is it like a net of tiles belong to one? is this potentially hundreds of connectors acrossed your roof that would be so many points of failure. if so that seems nuts and hardly worth the absurd cost just for aesthetics. feel like anyone who can afford this could just have whatever roof they want and then have their solar array farm nearby on their presumably many acres of land.

in the marine/rv world there are like walkable solar panels that you can literally just like walk on now, theres solar awnings, i dunno. just in my limited experience i'd be surprised if they dont have the christmas light problem (one goes out many go out) and solar arrays just seem to do awesome in panel configurations and i think in the consumer world theyre reaching 25% conversion, no idea what tesla is marketing but those guys are dorks with marketing anyways

How does one go about acquiring these?
