Calculation of PV array dimensions
A. Frames v.2012 and v.2020
Hc (mm) = (Height Ref +graduation) x nb. rows + 310
Wc (mm) = (Width Ref. +36.5) x nb. columns + 310
B. Half-frames v.2022
Hc (mm) = (Height Ref . + Intermodular Graduation) x nb. rows + 310
Lc (mm) = (Width Ref. +40) x nb. columns + 310
In order to
easily calculate the PV array dimensions of your project, don’t forget to use
our PV array calculator available on our website in the « downloads » section
:
Support battens of the mounting system
| A. Frames v.2012 and v.2020 | B. Half-Frames v.2022 |
|---|
| 
The sections of the support battens are determined according to climatic
loads.
Use roof battens only if the section is suitable to support climatic loads and
if they are positioned according to the GSE battening plan (refer to the
online documents)
Recommended batten section: 27×100 mm (use minimum 25×50 mm to be
compliant to the Eurocodes)
Junction to the lower roofing elements
A. Junction in the middle of the roof
Laying of the waterproofing strip on:
| Slate: | Other tiles: |
|---|---|
B. Junction to the gutter
When installing all the way to the eaves, the PV field can be connected
directly to the gutter with a waterproofing strip or a drip flashing.
N.B.: the drip flashing isn’t included in the GSE kit
GSE In-Roof frames grid
A. Frames v.2012 and v.2020
- Fix the 1st frame through the 2 central fixing points
- Assemble and fix the other frames
- Pre-drill and fix the 4 other fixing points
| Plate fixing point (without pre-drilling)
---|---
| Plate fixing point (pre-drilling 10mm)
| Clamp fixing point (6 clamps) (pre-drilling 10mm)
| Clamp fixing point (4 clamps) (pre-drilling 10mm)
Warning: Do not screw too deep into the frame
B. Half-Frames v.2022
- Fix the 1st half-frame through its middle fixation point and through the 2 other fixation points on the upper plot already pre-drilled.
- Assemble the other half-frames laterally thanks to the ergot and vertically. Fix them the same way than described in 1.
| Frame fixing point (already placed, without predrilling)
---|---
| Frame fixing point (already pre-drilled at 10mm)
| Clamp fixing point (4 & 8 clamps) (lateral interlocking needing a 10mm pre-
drilling)
Warning: Do not screw too deep into the frame
Adjust the graduation between rows according to the module length (cf p.1)
Lateral flashings
-
Place the wedges beneath the ridges of the frames
Position 1: wedges for Half-Frames v.2022. Position 2: wedges for Frames v.2012 and v.2020. R for the Right side of the PV array.
L for the Left side of the PV array.
-
Flashings are placed on each other (150mm overlapping)
-
Straight to the clamps position, pre-drill through the flashing, plastic frame and wedge.
Solar panels
A. Cabling – Grounding
| Fix the micro-
inverters on a batten in the central holes of the frames.
---|---
| The central
holes of the GSE In-Roof frames allow an easy connection of module frames and
micro-inverters grounding cables.
B. Laying of the solar panels
The module is maintained with the upper protrusions and must rest on the pads. Pre-drill with a 10mm drill bit the fixing points of the clamps on the frame, then screw the clamps in their pre-drilled position.
DO NOT USE AN IMPACT SCREWDRIVER TO FIX THE CLAMPS.
It is necessary to use a normal screwdriver to ensure that the clamps remain
mechanically still over time.
Top/corner flashings
Position the attach angles and the top flashings so that it fits the module thickness. Make cuts on the attach angle at the position of the GSE panel corrugations.
Assemble the top flashing with the junction and the corner pieces.| 
---|---
Apply a seal joint at each junction between 2 pieces.| 
If needed, you will have to cut the corner flashings according to the GSE In- Roof frame selected and the thickness of the module as defined in the following table:
| Module thickness | 30-34 mm | 35-39 mm | 40 et + |
|---|---|---|---|
| Frames 2012 | Waterproofing strip* | Needed cut | No cut needed |
| Frames 2020 | Needed cut | No cut needed | Waterproofing strip* |
| Frames 2022 | Needed cut | No cut needed | Waterproofing strip* |
- Laying of a waterproofing strip on top of the PV field
Follow the 3 steps below to cut the corner flashings:
Cut the corner flashing in two distinct pieces.| Adjust the height of the corner flashing by overlapping the two pieces.| Once the height adjusted, drill the overlapped pieces with a 4,5mm drill bit and fix it with a rivet.
