Determining The Collector Row Clearance Z - Viessmann VITOSOL 200-FM SV2F Design Manual

Design Information

Determining the Collector Row Clearance z

z= h sin (180°- (α+ β))

sin β
Legend:
z=Collector row distance
h=Collector height
200-FM model SV = 93c in. (2380 mm)
200-FM model SH = 41c in. (1056 mm)
=Collector angle of inclination
200-FM model SV = 25° - 60°
200-FM model SH = 25° - 80°
=Solar angle
=(90° - 23.5°) - Latitude
56
IMPORTANT
When installing several collectors in series, maintain a
distance of "z".
Example:
Vitosol 200-FM, Type SV (Vertical Collector)
Toronto is located at approximately 43° latitude.
1. Determine the angle of the sun . This should be
chosen so that the midday sun December 21 falls on
the second row of collectors without being obstructed
by shadows.
Solar angle :
= (90° - 23.5°) - latitude
(23.5° should be accepted as constant value for
northern latitudes)
=(90° - 23.5°) - 43°=23.5°
2. Calculating dimension "z":
h= 2380 mm
= 45°
= 23.5°
z= 2380 mm  sin (180°- (45°+ 23.5°))
sin 23.5°
z= 2380 mm  sin 111.5°
sin 23.5°
z= 218.6 in. (5553 mm)
