Information
Analytic expression for daily solar profiles
Hypothesis and equations
Analytic expression for daily solar profiles (irradiance in [W/m²]) on a south-facing surface.
This expression is obtained by developing the function which represents the irradiance in Fourier series, considering it periodic with a period of 2*day. This method is equivalent to the standard EN 61725.
