Why not on your home roof: because I don't have a home roof or a place to run the cable to the car. I could ask the landlord if they'll allow me to pay for solar panels on their building but I still don't have a driveway as mentioned

Why doesn't the Leaf have it: afaik the leaf is a normal car, not like the Aptera that I'd be looking to buy. Even the Lightyear One was claiming to be more efficient than normal but pretty disappointing in how much range you get from the solar roof. Still more than zero though, so yeah ask them why they don't sell that variant ¯\_:|_/¯ While we're at it, let's find out why there isn't a smartphone that fits my niche (modern chipset with dual frequency GNSS for less than twice the price that competitors charge for it, operable with one average-sized hand, sdcard slot, and ideally a headphone jack but at this point I'd settle just for a bit of storage and really don't feel like it should be a hard-to-find device) or a laptop that makes sense (arrow keys and no annoying tapered edges that don't fit a network port, for example, already limits your options to a tiny percentage of the available systems)
