Solar Constant general information powerpoint

A powerpoint about the Solar Constant a topic in physics which is needed for calculations with solar panels

1. Solar Constant Nicolas Böhme

2. Solar Constant The solar constant is the amount of solar electromagnetic radiation per unit area that is received outside Earth's atmosphere in a plane perpendicular to the rays. approximately 1361 w/msquared Measured at the outer surface of the earth AU

3. Factors which affect solar constant Solar cycles: The Sun undergoes approximately 11-year cycles of varying solar activity, known as solar cycles, which affect the amount of solar energy emitted. Solar Flares Periods of intense solar activity, such as solar flares and sunspots, can cause short-term increases in solar radiation. Earth's orbit. Earth does not go in a perfect circle so r changes

4. Finding Solar constant 1 AU is the distance from sun to earth Sphere is the energy distribution of the sun L is the luminosity of the star S is average energy per unit

5. Applications Solar panels To know how much energy they receive

6. Applications Climate Solar Constant r epresents the total energy input from the Sun that drives weather, climate, and the entire biosphere. Increase of the constant will result in temperature changes
