How the PV Module Tilt Angle is Set
Before assembly, determine what the PV
Module tilt angle will be. This is critical
because during assembly, certain
components must be assembled in a
particular manner in order to achieve that
desired tilt.
The tilt angle is set through the
combination of the vertical span between
the two Pole Channels, the Rail attachment
point (a, b, or c) of the Expandable Strut
and the length of the Expandable Struts.
(See Figure 1-1)
When setting this combination of
components, one aspect of high structural
importance is the relative elevation
between the Lower Pole Channel and the
Strut-to-Rail attachment point. In order to
achieve optimum structural endurance and
support, the Lower Pole Channel must be
at a lower elevation than the Strut-to-Rail
attachment point. (See Figure 1-2)
CAUTION:
Use care while
working around
the structure
during assembly.
There could be
components that
create hazards or
obstruct free
movement,
causing serious
bodily injury. Many
of these are at
head/eye level.
Move slowly and
with care around
the work area.
