# What countries use solar energy?

Suppose that Saudi Arabia would need a complete of 240 TWh in 2020. And suppose that 1 GW ability would produce 2 TWh (due to the geographic location of Saudi Arabia). Then Saudi Arabia would have to put in 120 GW of photovoltaic solar (PV) energy capacity.

What amount of solar energy panels would they require?

Really, why don't we take 250 Watt solar power panels.

After that Saudi Arabia would need:

250 Watt x 4 = 1 KWh

1 KWh x 1, 000, 000 = 1 GWh

1 GWh x 120 = 120 GWh

4 x 1, 000, 000 x 120 = 480 million solar energy panels (of 250 Watt each).

Why don't we ensure it is a circular total of 500 million solar energy panels (of 250 Watt each).

How much surface of Saudi Arabia would they should cover with solar panels if they wanted to develop 1 extreme huge **solar power plant** (in square km's)?

How big each cell is 167.5 cm (length) and 100, 1 cm (width). The surface of every cell is 1.676675 square meter.

500 million x 1.676675 square meter = 838, 337, 500 square meter = 838.3375 square km

an area of 30 kilometer by 30 kilometer would end up in 900 square km, that ought to be enough.

And what kind of opportunities will Saudi Arabia have render to realize these types of a serious solar plant?

Price per solar power? How about $250? And 20percent rebate?
