Here we are supposing a panel size of 350w for the calculated size of 18tw of solar plants. A total of 51 42 billion solar panels would be needed to power the entire world on solar energy. How do we arrive at this number.

Currently the existing infrastructure in the nation churns out over 4000 billion kwh every year. That s roughly the size of spain. That means a daily average of almost 11 billion kwh. The sahara desert has eighteen times the surface area needed to power the entire world.
