@Dr.Gehrig I don't have all the answers. It depends on use cases and your climate. No need to get all bent out of shape just because I pointed out some flaws in your naive thinking. Which solar projects are you talking about? I haven't seen any practical solar cars being used in real life. Most of them are just for experiments or to show how efficient they can make a car to be. they aren't designed for every day comfort and practicality.

How expensive is it to setup connections to the home? Is it worth it financially? If you just want backup power isn't a lfp battery at home much cheaper?

How long to charge cybertruck by solar? Weeks?

@Dr.Gehrig if you park in the sun all the time, how much energy will be used by the thermo management for the battery? Also to keep the cabin cool for when you get into the car? It pretty much uses up most of energy it gets from solar and little to add to the battery.

@Dr.Gehrig lol sure sure. Know-it-all. Maybe Tesla will hire you as chief designer for coming up with such a brilliant idea to put solar panels on CT, or any EVs that's intended for every day use for that matter.

@Dr.Gehrig likewise. Speaking of humility look at yourself.

@Dr.Gehrig read my original reply again. It depends on the use cases and climate you live in. Are your calculations based only on one scenario? Such as always parking in the direct sunlight? How much energy is needed for cooling the battery in the heat of summer in direct sunlight? What if you live in a Nordic environment much of year is cloudy and covered in snow? What will be the ROI for putting solar panels in the car then? Even if you could park in the sunlight most of the time, who would want to? It's so uncomfortable to get into a hot car every time. That's why most people choose to park in the shade or garage if possible. You can run the AC and preconditioning just before getting in the car but that negates some of the energy you generated from the panel so what's really the point? Also the heat is not just uncomfortable but also bad for many electronic components and shorten their service life. Did your highschool math take all that into account? Real life is much more complex than highschool math my naive child
