The Aptera Forum
The solar panels also power ventilation to help keep the interior at outside temperature
Solar reflective glass, which Zi suppose you can tint ” if needed”
The resin filled sandwich core composite is suupose to have good insulation too.
Skin also has coolant liquid channels.
Line 123 of Aptera's FAQ Spreadsheet says the windows CAN be tinted.
@Andrew Dunn If the vehicle has the solar hatch there won't be a rear "greenhouse" with which to contend but, as all versions have the solar dashboard, drivers won't be able to employ a reflective windshield cover...
There are, however, some non-darkening IR-reflective films on the market that are nearly transparent and can be used on windshields.
Drivers won't be able to employ a reflective windshield cover IF they want full solar charging capability. Your choice to cover or not, HOWEVER...
You will most likely be able to click your phone 5 minutes before you leave & your car is heated/cooled to whatever temp you set. Even my compliance Fiat EV has that.
@kiteboarder ...which, of course, immediately depletes the charge the solar cells have provided. Damn those pesky physicists and their "conservation of energy"! 🤣
Depending of course on ambient temp & how long you were parked. Anyway, it's not much of an issue with available range of 625% to 2,500% of the US average daily drive.
@kiteboarder ...unless you're not on the average daily drive and your vehicle isn't fully-charged. We have no idea how efficient the heating or cooling system of the Aptera will be - and the interior of any vehicle with a black upper surface and large windows will heat considerably no matter the ambient temperature. I'm assuming that @Andrew Dunn was thinking in terms of an Aptera spending the workday sitting in a parking lot - not a momentary stop to pick-up milk at the grocery store.
Yep sitting in the sun for 8 hours time scenario with ambient of 85-90 would be my summer situation.
My EV takes about 0.08kWh to cool down after baking in hot SoCal sun. That's 2.1% of Aptera's workday solar charge.
They elaborated on very thin solar cells. They could be using thin film cells like Solar Frontier does.
You can park it in the shade and it will produce electricity. It even works in a lit parking lot overnight (albeit less kwh) and when partly shaded.
