@JOHN W. DARBY Aptera is still busy designing the vehicle: I’m sure that any accessories that they may choose to offer won’t be available until they’re closer to production.
As to a vehicle cover – the whole point of Aptera is that it can charge from the sun – and that the solar panels will provide power to run the ventilation system when the vehicle is parked. If one covered the vehicle, there’d be no way for the sun to reach the solar cells.
Covers are for winter to keep the snow off, there isn’t much sun in the winter so you aren’t losing anything by covering it. Lot’s of generic car covers should fit. I never bother with expensive covers on ,y Tesla, a $60 Amazon cover works fine. I cut a flap for the charging cable and reenforce it with duct tape.
All plastic covers are pretty limited to function as an all purpose cover. I would definitely seek a cover that would be waterproof and breathable. Once APTERA enters market, I believe manufacturers will make a hybrid specific cover for vehicles with solar panels.
