I'm curious - I still haven't seen any details on how these are installed. How are things wired - does the wiring run under the shingles themselves? Also, how does it work with odd sized/shaped roofs - e.g.: something that isn't exactly a multiple of 1/2 a shingle?

There are probably electrified tracks which are screwed down onto the rafters, similar to the way wooden risers* are put down for clay tiles to attach to. The tiles attach using metal clips or nails. SolarCity acquired Zep Solar a while back, who designed quick installation solar mounting systems. I assume they're using that team to design something fully integrated and fast to install. You'll probably just snap the tiles onto the rails after they are screwed (bolted?) down. The tracks would just plug into each other like Christmas lights.

They said they're producing plain tiles without panels inside for edge pieces and north/east/west roof faces.

I expect for the odd sized they would have border shingles that match and are easily cut. Wiring seems like one of the hardest things to get right with these, especially given the environmental conditions!
