As to the total output of the Sun thats about 93 billion megatons of TNT equivalent per second.

. 3846 10 26 watts or 3846 10 33 ergssec. That is 38 followed by 26 zeroes. The suns interior has a temperature of 14 to 15 million kelvin and its surface about 6000 kelvin.

6600 K Temperature at top of chromosphere. For comparison purposes one billion only has nine zeroes. According to the World Book Encyclopedia about 126 trillion horsepower is sent to earthDividing the converted value of 94 10 16 watts by 2 10 9 gives a total power of 47 10 25 watts.

B Part of this is absorbed and reflected by the atmosphere so that a maximum of 130 textrm kWm2 reaches Earths surface. In 1 second the Sun generates 38 x 1026 Joules. The Suns impact on climate has only recently been investigated.

The Stefan-Boltzmann equation then gives the energy flux emitted at the suns surface. If the Sun were gradually. This translates to about 8 x 1020 Corvettes running at full power per second.

This means that not all of that energy makes it here. S S 567 10 8 Wm 2 K 4 5800 K 4 63 10 6 Wm 2. It is a star of surface temperature 6000 K and a radius 696x10 8 m.

The intensity of sunlight reaching the earth is 1360 Wm2. Note that works out to over ten million such power plants per human on Earth. Sources estimate a global average of between 164 watts to 340 watts per square meter over a 24-hour day.

If r S is the radius of the Sun the total energy it emits is S S 4πr s2. Sunspots like these can cause temporary decreases in total solar irradiance of the Earth of 02 as they pass across our side or the Sun during a week or ten days. 4400 K Temperature at bottom of photosphere.

Who are the experts. The radius of the sun is about 700000 kilometers. Take the power output of the Sun to be 400 times 1026 textrm W.

Right now most residential solar panels have power output ratings of between 275 and 400 watts of DC power per module. 386 x 1023 kilowatts 386000000000000000000000 kilowatts Total solar power received on Earth. Compare that to the largest power plant have total energy generation of 3-5 GW.

In other words its the maximum generation you can expect from a panel. 2500 km Sun. The sun has about 5 x 1023 horsepower which is 5 with 23 zeroes after it.

125 mb Effective temperature. Currently most solar panels on todays market usually produce between 250 and 400 Watts of power your actual output will depend on factors like shading orientation and sun hours. So every second the Earth receives the equivalent energy of 42 megatons of TNT from the Sun.

Please pause for a moment to count them all to develop a respect for how much energy the sun produces. With a 30-panel system youll be producing more than enough electricity per year to match all of your electricity usage and maybe more. Experts are tested by Chegg as specialists in their subject area.

When blocked by clouds or reflected off other objects sunlight is diffused. The intensity of sunlight reaching the earth is 1360 Wm2 Part A What is the power output of the sun. In the UK that is 380 quadrillion Joules every second and in short scale numbers it would be 380 septillion Joules.

Keep in mind that the sun is almost 93 million miles from the Earth. The power output rating tells you how much electricity a solar panel can produce under ideal operating conditions. This amount of missing irradiance is insignificant compared to the Suns total energy output but equivalent to all that man produces and consumes in a year.

500 km Chromosphere thickness. What formula can be used to find the total energy being produced from the Sun in Joules per second. Each year as of 2010 the world is estimated to use 5 x 1020 Joules of energy.

Total power output of the sun. 5772 K Temperature at top of photosphere. Ever look up on a hot day and say I wonder how much energy the sun produces Well its enough this hour to power 2880 trillion light bulbs.

0868 mb Pressure at bottom of photosphere optical depth 1. The sun has a radius of 695 x 10 6 m 4 giving a surface area of 607 x 10 18 m 2. P W Part B What is the intensity of sunlight on Mars.

Clearly an enormous amount of power when we consider that the entire worlds energy usage is. In the image below you will see precisely 2880 trillion light bulbs. Who noted in 1854 that the Suns own gravity could supply an appreciable amount of energy.

Power output of the Sun 716x10-7 r 2 T 4 716x10-7 x696x10 82x6000 4 716x10-7 x 484x10 17 x1296x10 15 45x10 26 W. A What is the power output of the sun. S-8Nuclear Power S-9Nuclear Weapons The Sun is the source of most of the energy on Earth--the power source for plants the cause of flows of atmosphere and of water the source of the warmth which makes life possible.

Dividing 175 billion megawatts 175 billion megajoules per second by 4184 billion megajoules per megaton yields about 42 megatons. 30000 K Photosphere thickness. Thus the total power output of the sun is 64 x 10 times 609 x 10 18 m 2 which is equal to 39 x 10 26 watts.

Calculate the area in textrmkm2 of solar energy collectors needed to replace an electric power plant that generates 750 MW if the. 174 x 1014 kilowatts 174000000000000 kilowatts Solar. This figure is estimated by NASA to be about a quarter of Earths average total solar irradiance.

Using the preceding equation we can calculate its power output. Recent studies show that an increase in solar output can cause short-term changes in Earths climate but there is no firm evidence. B What is the intensity of sunlight on Mars.

The surface area of a sphere with a radius r is 4πr 2.
