3.0 Installing Roof-Mounted Solar Panels. (For slate tiles)

A special surface mounting system is available for slate tiles. Contact Atmos for details.

4.0 Installing Solar Panels on Flat Roofs

Solar panels may be installed on flat roofs using a separate A-frame. The frame may be

secured to the roof by screws/bolts through the feet, or by ballasting. The securing plates for

these two types are different, please ensure you have the correct frame for the chosen

method. Check that the sensor has been fitted to the panel before taking up to the roof.

[Note that an alternative solution is as follows: If the panels are mounted on a timber frame,

with mounting face for the solar panel at 35 degrees to the horizontal, which is completely

enclosed, this prevents any upward loading. Contact Atmos for more details.]

4.1 Fixed Frame Method

4.1.1 Assemble the relevant frame, as shown in Figure 4.1 below, using the supplied

nuts, bolts and washers (additional assembly instructions may be found in the frame

shipping box).

1 or 2 Module Lon

2 or 3 Module Standard

1. Fixing foot

2. U

3. Bracing strut

4. Panel su

4.1.2 Position the frame in the required area on the roof, drill through the holes in all

four mounting feet, and fix to the roof using screws or anchor bolts depending on the

roof material. Note – please refer to table 1, for maximum building heights and

screw/bolt strengths.

The roof may need to be opened to find a suitable supporting wall to withstand the

potential uplift force of the solar panel in windy conditions. Please also note that the

force is an uplift force and so the fixing may have to be located a considerable

distance down into the wall.

4.1.3 The foot plates should be weather sealed by felting over the base plates, using

a suitable membrane such as EPDM.

4.1.4 The two supplied silicone pipe flashings should be used to seal the flow and

return roof penetrations. These flashings should be further sealed with EPDM

membranes.

4.1.5 Once the frame has been fixed, locate the solar panel in position, using the

coach bolts on the panel support strut to position the panel on the frame. Ensure the

solar panel is level and then drill Ø 9mm holes through the top and bottom lips of the

panel in line with the centre of the support struts. Secure the panel to the frame with

the bolts supplied.
