Question

Estimated value of solar constant is______________

Answer 1

Solar constant:

1. At Earth's distance from the sun, a solar constant is a measurement of the energy of solar electromagnetic radiation absorbed per meter squared per unit of time.
2. The solar constant is used to calculate the rate at which energy is absorbed by a unit surface, such as a solar panel.
3. It is measured by one astronomical unit from the Sun on a surface perpendicular to the rays.

Hence, the estimated value of the solar constant is $1.366\frac{\text{kw}}{{\text{m}}^2}$.
