I think your math was wrong.
For 2022, electricity usage was ~4.07 trillion kWh. But the 1.5 kWh for a solar panel is per day...not per year. So to calculate total need, you need to multiply 1.5 * 365 to get kWh for the full year...which is the 4.07 trillion number.
- 4.07 trillion kWh / (1.5 kWh day * 365 days) = ~7.4 billion panels (7,433,789,954.337)
- 7.4 billion panels * 17.55 sq ft = 130 billion sq ft (130,463,013,698.61)
- 130 billon sq/ft * 0.00000003587 (1 sq ft / sq mile) = 4,679.71 sq miles
- 4700 sq miles -> 68 x 68 mile square (sqrt of 4700)
So if you factor in overhead, reduced output at certain time, 100 x 100 sq miles of solar would get it done.
