Jorgustin s plan assuming a cost of 250 per panel would total around 767 billion a fraction of the united states government s 3 6 trillion expenditure in 2012 but an investment that.

How much solar panel to power the world. You might think it s a simple math question. Solar panels usually produce between 250 and 400 watts of power.

Here we are supposing a panel size of 350w for the calculated size of 18tw of solar plants. The actual output you see depends on factors like shading orientation and sun hours. If a solar panel is rated to produce say 360 watts and it s about 3 and feet wide by 5 and feet long then each square foot must produce about 20 watts right. A total of 51 42 billion solar panels would be needed to power the entire world on solar energy.
