Aptera solar panels

(1/1)

kallisti5:


Anyone care to do the back of the envelope math on the benefit of the solar panels on the Aptera?

I personally think they're being pretty honest with the range increases due to them.
40 miles per day in sunny CA, 4 miles per day somewhere like London.

26 cells on the hood.  "roughly the same on the roof", 6 on the rear.   12? on the dash?
That's roughly 70 cells total.   "roughly 400w absolute best case based on similar cell count panels on amazon."

1kw per 10 miles.  100kw pack nets 1000 miles.


eeh. my math is falling apart here, however it sounds realistic.

   Every time that I hear the claim "Game Changing" or anything of that sort, the claim usually smells like dead fish! I'm not wasting my time to watch a video full of ridiculous claims.  If you want us to hear your claim than spell it out so that we can read it instead linking to a video hoax.

thm_w:
Are you calculating the watts based on cell count? Or that was someone else. You can't really do that as cell size varies.
Either you find the area they've provided (I didn't see it immediately provided) or trust their number of 700W.

To keep your math together, start by not mixing up kW and kWh.  ::)
Extra credibility points for capitalizing the W.
