I don’t know much about this matter, coming from the east coast, but do know, now living the the SW....that tinted windows can be important. Some film material like non metallic nano technologies are used and have claims to help with heat and UV reflection without interference with electronics. I understand the Aptera will have solar power roof panels to assist to keep the interior close to outside temperatures but was wondering what the plans might be for UV/ heat reflection on the glass panels.(I.e., for occupant comfort and protection to interior materials.) In my state side windows can be tinted to a certain tint level, whereas back east “tinting” of windows/ amount of windows tinted was more restrictive.
