What is the Solar Constant, and what does it represent?

We Answered:

The so-called solar constant is about 1367 W · m?2 (1.96 cal · cm?2 · min?1).

It represents the total solar radiant energy flux incident upon the top of the Earth's atmosphere at a standard distance (1 astronomical unit, 1.496 × 10^8 km) from the Sun.
