How Many Sqkm Of Solar Panels To Power The World

It would only take 191 817 square miles of solar panels to power the entire earth.
How many sqkm of solar panels to power the world. Most people probably know about solar energy that we would only need to harness a tiny fraction of it to power the entire world e g. Photovoltaic pv systems use solar panels either on rooftops or in ground mounted solar farms converting sunlight directly into electric power. Solar power plants use one of two technologies. We receive a staggering 1 74 10 17 watts of energy from it.
If you wanted to power the entire u s. Solar power is more powerful than many people realize. The batteries you need to store the energy to make sure you have 24 7 power is 1 mile by 1 mile. If we were to think of the solar panels needed to power the entire world a significantly large portion of that would be needed for the u s.
The sahara desert has eighteen times the surface area needed to power the entire world. To put this into perspective this is about 10 000 times more. Here we are supposing a panel size of 350w for the calculated size of 18tw of solar plants. Currently the existing infrastructure in the nation churns out over 4000 billion kwh every year.
How do we arrive at this number. A total of 51 42 billion solar panels would be needed to power the entire world on solar energy. With solar panels it would take a fairly small corner of nevada or texas or utah. That means a daily average of almost 11 billion kwh.
