Why though? Wouldn’t it make more sense to just have solar panels at your home where the power can be routed to batteries/ home power/ sell to the grid and configured optimally?
To make it work when you live in a place where you park on the street and can't run wires to the car?
The aptera design has flexible panels molded to the body under the clear aerodynamic shell. It shouldn't suffer from aerodynamic losses but the panels probably lose efficiency from heat.
I guess it’s a nice option to have in the market but if what you’re going for is minimal carbon emissions impact it would be best to put those solar panels on house roof I think.
