Example 1

What is the maximum Solar altitude of Hong Kong?

b = 90^o - ( L - d)

where b is Solar altitude, L is Latitude (see Fig. 2), d is Solar declination.

In summer, Latitude is 22.2^o
Solar declination is 23.5^o

Therefore, the Solar altitude is 91.3^o

In winter, Latitude is 22.2^o
Solar declination is -23.5^o

Therefore, the Solar altitude is 44.3^o
