# Solar constant

The solar constant is the amount of power that the sun emits per unit of area. It is typically measured in watts per square meter (W/m2). The average solar constant over the whole earth is about 1366 W/m2.

#### What is solar constant formula?

The solar constant formula is a mathematical expression that describes the amount of solar radiation that reaches a given point on Earth's surface. It is typically expressed in units of watts per square meter (W/m2).

The solar constant is a measure of the average amount of solar radiation that Earth receives from the Sun. It is not a measure of the amount of sunlight that reaches Earth's surface, because Earth's atmosphere absorbs and reflects some of the incoming sunlight.

The solar constant formula can be used to calculate the amount of solar radiation that would reach the Earth's surface if there were no atmosphere. This value is called the "extraterrestrial solar constant." The extraterrestrial solar constant is about 1367 W/m2.

The solar constant formula can also be used to calculate the amount of solar radiation that actually reaches the Earth's surface. This value is called the "terrestrial solar constant." The terrestrial solar constant is about 1000 W/m2.

The difference between the extraterrestrial solar constant and the terrestrial solar constant is due to the Earth's atmosphere. The atmosphere absorbs and reflects some of the incoming solar radiation, which reduces the amount of solar radiation that reaches the surface of the Earth. What is the value of solar constant in W m2? The solar constant is the amount of power that the sun emits per unit area. It is measured in watts per square meter (W/m2). The value of the solar constant is about 1,368 W/m2. What is the unit of solar constant? The unit of solar constant is the amount of power that the sun emits per unit area. The sun emits a lot of power, but it is spread out over a very large area, so the solar constant is actually quite small.

##### What is solar constant PDF?

The solar constant is a measure of the power output of the sun. It is defined as the amount of power that the sun outputs per unit area, and is typically measured in watts per square meter. The solar constant fluctuates slightly over time, but is generally considered to be around 1366 watts per square meter.

The solar constant can be used to calculate the power output of a solar panel. This is done by multiplying the solar constant by the area of the solar panel. For example, a solar panel with an area of 1 square meter would have a power output of 1366 watts.

The solar constant can also be used to calculate the amount of power that a solar system can generate. This is done by multiplying the solar constant by the total area of all the solar panels in the system. For example, a solar system with 10 square meters of solar panels would have a power output of 13,660 watts.

The solar constant can also be used to calculate the amount of power that a solar system can generate per unit of area. This is done by dividing the solar constant by the total area of all the solar panels in the system. For example, a solar system with 10 square meters of solar panels would have a power output of 136.6 watts per square meter. Which planet has the highest solar constant? The highest solar constant is found on Mercury. This is because Mercury is the closest planet to the sun. The solar constant is the amount of power that the sun produces per unit area.
