An Algorithm to Determine the Optimum Tilt Angle of a Solar Panel from Global Horizontal Solar Radiation

Figure 2

The standard error of the mean (SEM) of the tilt angle values (a) and of the monthly average of the daily global solar radiation values (b), computed for the summer months (solar declinations ā€“ ) as a function of latitude. The linear fits provided the correlation coefficients and , respectively.
