CONSTANT:

Solar constant:

  • The solar energy reaching unit area at the outer edge of the earth’s atmosphere exposed perpendicularly to the rays of the Sun at the average distance between the Sun and Earth is known as the solar constant.
  • It is estimated to be approximately 1.366 kJ per second per square meter or 1.366 kW/m2.

EXPLANATION:

  • From above it is clear that the value of a solar constant is 1.366 kW/m2 or 1366 W/m2. Therefore option 3 is correct.
