regulation.
b) The standard frame and frames kits are all designed to withstand
wind speeds of up to 130 mph (208 km/h) without damage, which
corresponds to the mid-range of Category 2 cyclones (US Saffir-
Simpson scale). For higher wind speeds, reinforcement of the
manifold and tube to frame attachment and frame to roof attachment
is required and must be approved for use by Apricus, a licensed
engineer and local authorities.
c) Refer to Section 5 for specific roof attachment details for various
frame options.
d) Other mounting methods in high wind regions may require
inspection and approval by a licensed engineer or the local building
department. It is the responsibility of the installer to ensure that the
frame mounting is of suitable strength.
e) In high wind regions, be advised of the following: Collectors installed on flat roofs with full front and rear
exposure, can experience vertical pull forces up to 268.4 lbs (122 kg) in a 130 mph (208 km/h) wind on the
middle, rear round foot attachment point alone. The horizontal force pushing against the collector can reach
396 lbs (180 kg) on the middle, front round foot. Both of these values are based on an install angle of 60
°
,
with decreased uplift and horizontal force values at lower installation angles.
The direction of load on the feet changes based on the angle. For example, at a 30
°
collector angle with a
rear wind, there is an uplift force on the middle, front foot of 49 lbs (22 kg). At a 45
°
collector angle, however,
the same wind will actually create a downward force of 15 lbs (7 kg
)
, because the collector is trying to tip
forward. The table below provides peak vertical pull forces and horizontal (pushing) forces for an AP-30
collector. These values represent both rear and frontal winds. The highest force of 396 lbs (180 kg) on the
middle, front foot at a 60
°
collector angle is actually from a frontal, and not rear, wind as it is trying to tip the
collector backward.

f) Based on the figures provided in the table above, the weight of individual concrete blocks or the strength of
fixation points requirements can be determined. A safety factory of at least 1.2 should be used or as
specified by local authorities, whichever is higher. If using concreted blocks under the feet, connecting the
blocks together, particularly front and rear, is advisable as it can help spread the load. This applies
particularly to the middle legs which are exposed to the peak loads. Before ballasting the system with
concrete or other weights, be aware of the total weight live and dead load capacity of the roof structure and
determine if the roof can safely handle this attachment method.
Wind related frame and collector damage is not eligible for warranty claims.
󱚡 WARNING
Failure to implement suitable collector mounting methods to withstand wind loading may
result in damage to the solar collector, extreme damage to property and even death.
