Determining the Collector Row Distance “z”
Legend:
z=Collector row distance
h=Collector height
α=Collector angle of inclination
β=Solar angle
When installing several collectors in
series, maintain a distance of “z”.
Example:
Model SV
Toronto is located at approx. 43°
latitude.
1. Determine the angle of the sun β.
This should be chosen so that the
midday sun D ecember 21 falls on the
second row of collectors without
being obstructed by shadows.
Solar angle β:
β=90 °-23.5°-latitude
(23.5° should be accepted as
constant value for northern latitudes)
β=90 °-23.5°-43°=23.5°
2. Calculating dimension “z”:
h= 2380 mm (for model SH use
1056 mm)
α= 45°
β= 23.5°
z=
2380 ⋅ s in(180° − (45° + 23.5°))
sin 23.5°
z=
2380mm ⋅ s in111.5°
sin 23.5°
z=5553mm / 218.6”
