The units are in solar flux units (1 sfu = 10-22.m-2.Hz-1). If we multiply this area by the amount of energy per unit area - the solar "insolation" mentioned above, we can determine the total amount of energy intercepted by Earth:Plugging in values and solving for E, we find that our planet intercepts about 174 petawatts of sunlight... quite a lot of energy!Since Earth is not completely black, some of this energy is reflected away and not absorbed by our planet. Pressing Submit will validate the entered values and output the relative flux.
The Global Solar Atlas provides a summary of solar power potential and solar resources globally. Any object with a temperature above absolute zero emits electromagnetic (EM) radiation. Any object with a temperature above absolute zero emits electromagnetic radiation. A planet completely covered with snow or ice would have an albedo close to 100%, while a completely dark planet would have an albedo close to zero. To determine how much energy Earth absorbs from sunlight, we must multiply the energy intercepted (that we calculated above) times one minus the albedo value; since Now that we have a value for the energy flowing into the Earth system, let's calculate the energy flowing out.The Stefan-Boltzmann law tells us how much infrared energy Earth will emit The law of conservation of energy tells us that the energy emitted must be equal to the energy absorbed. This solar irradiance calculator takes data collated over a 22 year period to provide monthly average irradiance figures. For now, lets look at the simple case of a planet without air or water. For planets, that outgoing EM radiation takes the form of infrared "light". If you multiply KWhat do we mean by the "expected temperature" of a planet? The planet will continue to warm until the outgoing infrared energy exactly balances the incoming energy from sunlight. It turns out that oceans and atmospheres can have a big influence on a planet's temperature... we'll have more to say about that later. The specific value at Earth of 1,361 W/m2 is called the "solar constant". In the case of Earth, this EM radiation takes the form of longwave, infrared radiation (or IR "light"). This information can then be used to calculate the average daily power generation a solar electric system will produce in any given month. Mostly it means that we'll simplify things by leaving out the effects of an atmosphere or oceans on the average global temperature. the incident energy which is in the form of sunlight. It is provided by the World Bank Group as a free service to governments, developers and the general public, and allows users to quickly obtain data and carry out a simple electricity output calculation for any location covered by the solar resource database. As mentioned solar cell efficiency is the ratio of electrical output power (in Watt) to Directions: Select a location from the City pulldown menu, OR select "Enter Lat/Long ->" from the pulldown menu, and manually enter the latitude, longitude and time zone information in the appropriate text boxes. Scientist refer to the amount of In order to calculate the total amount of energy arriving at Earth, we need to know how much area is being lit. The area of a circle is pi times the radius of the circle squared. The value of the Stefan-Boltzmann constant (σ) is 5.6704 x 10Converting to the more familiar Celcius and Fahrenheit temperature scales, we get:Based on this calculation, Earth's expected average global temperature is This calculation of the expected temperature can be done for other planets as well. The units are in solar flux units (1 sfu = 10-22.m-2.Hz-1). That sunlight is absorbed by the planet's surface, heating the ground. Above mentioned solar cell efficiency formula or equation is used for this calculator. The equation or formula of solar cell fill factor is as follows: Fill Factor = P max / Voc * Ioc OR Solar cell Fill Factor = { (Solar Cell Efficiency * A c * E) / (Voc* Ioc) } Where, Voc = Open Circuit Voltage Ioc = Short Circuit Current
