Question

What is the rate of of solar energy in kw falling per m square on the sirface of the earth

Answer 1

Explanation:

At the upper reaches of our atmosphere, the energy density of solar radiation is approximately 1,368 W/m2 (watts per square meter).

Answer 2

The rate of solar energy which is falling on the surface of the earth is approximately 1kW per square metre.

• The solar energy that reaches the upper atmosphere of our planet is highly reduced when it reaches the actual surface of our planet.

• The amount of the solar energy that reaches the upper atmosphere is approximately 1368 watt per square metre of earth surface.

• But this energy is reduced while traveling through the atmospheric layers and only 1000 watt or 1 kilo-watt energy is able to reach the surface of our planet.

( 1 kilo watt = 1000 watt)
