5. MOUNTING SYSTEMS
Mounting hardware for Stiebel Eltron SOL 25 Plus solar collectors is available in the following configurations:
• 45° fixed mount, vertical orientation
• 45° fixed mount, horizontal orientation
• 30/45/60° fixed mount, vertical orientation
• 30/45/60° fixed mount, horizontal orientation
• Flush mount, vertical orientation
• Flush mount, horizontal orientation
Select the collector mounting kit that is capable of providing the required tilt and azimuth in a mounting location that is not subject to
excessive shading of the solar collectors. The mounting kit must be securely attached to a structure capable of supporting and maintaining
its integrity under the static and dynamic (e.g., high wind) loading conditions.
The type of mounting system that is best-suited to the installation must be determined by the designer, and must take into consideration the
details of the roof, wall, or ground upon which the collectors are to be placed, the latitude and orientation of the site, the space available
for the collectors, possible shading from nearby structures or vegetation, etc. The intended use of the system should also be an important
consideration. For example, if the house is a summer residence that requires only domestic hot water during summer months, and it is
located near 45° north latitude, the best performance can be gained by mounting the collectors at 30° from horizontal, as the best solar gain
will be obtained for summertime use
1 . In contrast, if most of the water heating (and some space heating) is required during winter months,
the best angle for collectors would be approximately 60° from horizontal, thus maximizing wintertime solar gain.
Stiebel Eltron furnishes mounting kits for each of the above arrangements and for each SOLKIT system. Table 5.1, below, gives details of the
kits and their components:

1 Peak altitude angle of the sun at noon, at 45° north latitude, at summer solstice, is about 68°. Maximum gain occurs with panels normal (perpendicular) to this angle, or
tilted 22° from horizontal, facing true south. Overall gain is not reduced significantly if collectors are within ±10° of the optimum tilt angle and within ±15° of true south.
