An Algorithm to Determine the Optimum Tilt Angle of a Solar Panel from Global Horizontal Solar Radiation
Table 6
Optimum tilt angle values and monthly mean of the daily global solar radiation values computed by means of the algorithm proposed in Section 2 applied to the monthly averages of the daily global horizontal solar irradiation data acquired from 1985 to 1989 at the site of Stockholm (latitude +59°17′N; longitude +18°03′E). The monthly mean of the daily global solar radiation was not acquired in the periods relative to the solar declinations , , and .
