These are 0.02% of the earth landmass.
Values are like this, when calculating conservative: 1 KWp needs an area around 10m². For enough maintenance distance multiply by 3 = 30m².
=> 1 Megawatt = 3 * 10m² * 1000 = 30.000m². => 1 Gigawatt = 3 * 10m² * 1000 * 1000 = 30.000.000m². => 1 Terawatt = 3 * 10m² * 1000 * 1000 * 1000 = 30.000.000.000m².

Values are like this, when calculating conservative: 1 KWp needs an area around 10m². For enough maintenance distance multiply by 3 = 30m².
Square root of 30.000.000.000m² = 173205m = 173Km. According to statista.com, the total earth landmass is 149.000.000 Km², so 30.000m² are 0.02% auf 149 million Km².
