Exploiting solar energy with collectors
The useful energy which a collector can
absorb depends on several factors. The
main factor is the total solar energy
available.
Annual global radiation

Whilst a global energy of
2
1 270 kWh/(m · pa) is available in
Freiburg, the value in Hannover is only
2
955 kWh/(m · pa).
1.2 Solar energy
The choice of collector type and its
inclination and orientation, are also very
important (see page 7). For optimum
economy of operation, careful
dimensioning of the system components
is also essential.
