SOLAR COLLECTOR INSTALLATION
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 sufficiently apart so that when the sun is at its lowest altitude, the collectors will not shade each other and cause efficiency 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).
