The Sun outputs 4 x 10^26 W of power in all directions. The entire population of the Earth currently uses roughly 15 Terawatts (1.5 x 10^13 W). Suppose in the distant future we put a giant solar panel in orbit around the Sun which captured one millionth (1 part in a million or 10^-6 ) of the Sun’s power. How much power would this solar panel capture and would it be enough to supply the Earth’s current energy needs?

a solar panel 0.75m x 0.5m is fitted to a mars probe. in orbit around the earth, the module is found to deliver 75 W. given that mars is about 1.5 times as far from the sun as is earth, how much power would it deliver in orbit around mars? Earth solar constant = 1360 W/m2

The Sun shines with a blackbody temperature of 5780 K and a total power output of 3.8 x 1026 w. The Sun has been doing this for 4.5 x 10 yr, during which time the surface temperature has increased by a few percent and the luminosity by 20%, ie. they have remained roughly constant.

Electromagnetic Wave Questions
2. Our sun has a power output of roughly 3.87 1026 watts (W). This energy is transmitted essentially uniformly in all directions. By the time this radiation reaches the Earth, which has an average distance from the sun of 1.50 x 10" m, what is the intensity? (Recall that intensity is defined to be power per unit area). 3. The energy from the sun is primarily in the infrared and visual wavelengths. The following table gives the...
