COLLECTOR ORIENTATION
Proper tilt angle for solar collectors is latitude plus 15°
This 15° additional tilt improves performance in the
winter, when the sun is weaker and at a lower angle.
The cost in performance in the summer when the sun is
high is overcome by the hours of sunlight and strength
of irradiation that occurs in the summer. Tilt mounting
accessory kits are available to set the proper collector
angle. Please call your local dealer for more information.
When the collectors are mounted one behind the other,
they should be spaced suffi ciently apart so that when the
sun is at its lowest altitude, the collectors will not shade
each other and cause effi ciency loss (see Figure 13). If a
collector must be installed horizontally, replace the upper
vent with rubber plug as shown below, in order to prevent
rain penetration (see Figures 11 & 12).
