Ok, this may be pretty far off but...

Elon Musk tweeted that a solar power tonneau cover option would be available that would provide 15 miles per day. I decided to try using this estimate, given the dimensions of the tonneau cover to figure out what the battery size of the Cybertruck would be.

I measured the area of the tonneau cover at about 77 in. x 77 in. This is equivalent to 41.2 sq ft. To account for error I rounded it to 40 sq ft.

77x77 = 5929/144 = 41.2

Solar panels produce a charge at a rate of

15 Watts per sq ft per hour

1 sqft = 15 Watts/hr

At 40 sq ft the solar tonneau cover would produce 600 Watts per hour

40 sqft = 600 Watts/hr

I’m guessing that the calculation was made anticipating 8 hours of usable sun.

600 Watts x 8 hrs = 4800 Watts or 4.8 kW.

4.8kW gives the model 3 LR 15 miles

4.8kW gives the Cybertruck 15 miles

The Cybertruck battery size is very close to the model 3 LR or 75kWh
