1. Introduction
The main purpose of this installation manual is to provide instructions and detailed procedures for installing and
maintaining Autarco pitched roof mounting system based on R6 type rails on buildings up to 20m in height.
1.1 Safety Symbols
DANGER! A danger symbol indicates a hazardous situation, which if not avoided, will result in death
or serious injury.
WARNING! Indicates a hazardous situation which, if not avoided, can result in serious injury.
ATTENTION! Attention statements are used to indicate where a part of the process or equipment
has a special requirement. Attention statements should be followed at all times.
1.2 Target Audience
This manual is intended for qualified personnel who installs an Autarco solar PV solution with R6 pitched roof
mounting systems. Before any further action, the installer must first read all safety regulations and be aware of the
potential danger to operate high-voltage devices such as PV modules.
ATTENTION! Qualified personnel means a person with valid license from the local authority for:
•Installing electrical equipment and PV power systems (up to 1000 V)
•Applying all applicable installation codes and using personal protective equipment (PPE)
•Analyzing and reducing the hazards involved in performing electrical work

2. Preparing for Installation
2.1 Safety Instructions
DANGER! Do not install during severe or sub-zero weather conditions.
WARNING! Never step or sit on the glass surface of a solar module.
The glass may break, resulting in shock or bodily injury. The module may also stop generating power.
WARNING! Always use the supplied parts to attach the solar modules and mounts.
Use of other parts is dangerous and may cause the solar modules or mounts to loosen or fall.
DANGER! Do not install this system on a roof with pitch > 60 degrees.
WARNING! The installation, maintenance, recycling and disposal of the mounting components
must be performed by qualified personnel in compliance with national and local standards and
regulations.
WARNING! Always install modules onto a minimum of two rails which are parallel to the shorter side
of the module.
Otherwise, loosening of the modules may occur due to expansion or contraction of the rails under
varying heat.
Any unauthorized actions including modification of product functionality of any form will affect the validation of
warranty service; Autarco may deny the obligation of warranty service accordingly.

2.4 Solar Panel Position Guideline
ATTENTION! DO NOT install this system on a roof with pitch > 60 degrees.
The minimum clearance of solar panels from the roof edges, gutters and ridges is typically 30cm (please check with
your local building regulations before proceeding).

2.5 Hooks and Rails Position Guideline
Before proceeding with the installation, make sure the hooks and rails are installed according to the dimensions
given below. This can be different per product:
•The maximum distance between two successive hooks (H1) is 120cm, but typically 60-80cm.
Refer to our calculator for the specific value.
•The distance between rails (R2) is between 0.5 and 0.7 times the length of the module (L). Please check
the allowed clamping position in the Solar Panel Installation Manual.
Refer to the ‘Mounting’ section of your module’s manual for the specific values.
•The maximum rail overhang distance (OH3) is 30cm.
As a quick guide, you may also use below table as a reference for installing Autarco modules:
Autarco Module
Module Dimension (mm)
Minimum Distance
Maximum Distance

0.52 x L
0.63 x L
MHL / TBL / TL Series
1903

0.45 x L
0.66 x L
The values for Hook Distance (H1) and Overhang Distance (OH3) are determined by wind zone, height of the
building and terrain code.

3.1 Marking the position of mounting hooks
Step 1 – Measure and identify the position of the mounting hooks using a measuring tool .
see section 2.5 (Pg 10) for the recommended hook (H1) and rail (R2) distances
Step 2 – Use a chalk or marker pen to mark the roof tile that will be removed for mounting.
This is the tile directly above the tile that the hook mounts onto.
Use the same procedure to mark on a corrugated or standing seam roof.

3.2 Mounting hooks onto the roof
Autarco offers various types of roof hooks depending on rafter, batten, corrugated roof and tile specifications.
In this manual we illustrate the installation procedure for the M2.AR6THX1 Hook 7a and the M2.AR6LHOOK.
Step 1 – Remove the roof tiles marked in 3.1, by sliding it upwards and under the roof tile immediately above.
For THX1 Hook
Step 2– Fit the M2.AR6THX1.1 Hook
onto the trough of the roof tile (downward curve of the tile). The
hook should secure both the roof tile and the batten.
For corrugated and standing seam roofs, fix the mounts as marked in Section 3.1.
Step 3 – Slide the removed roof tile back in place.

3.4 Clamping modules into the rails
3.4.1 How to assemble clamps onto the rails
End clamps 5 and middle clamps can be easily ‘snapped’ into the rails using the steps given below. We use the
middle clamp 6
in this illustration, but the steps are exactly the same for end clamps .
Step 1 – Hinge both legs of the clamp into the rail.
Step 2 – Press firmly down to snap the hinged legs in place.
Step 3 – Slide the clamp into the desired position on the rail and screw bolt to fix position.
3.4.2 Anchoring the rails (portrait & landscape):
Step 1 – Adjust the orientation of the bracket portrait or landscape by untightening the
screw and repositioning the bracket before retightening the screw.
Step 2 – Place your rail over the bracket attachment.
Step 3 – Adjust the height of the bracket attachment.
Step 4 – Push down on the rail until you hear a click.
Step 5 – Tighten the screw on the attachment.

3.4.3 Installing first module onto the rails with end clamps
Step 1 – Assemble the end clamps (see 3.4.1) into the R6 rails . Make sure less than 4cm of the rail is protruding
outwards from the end clamp.
Step 2 – Position the solar module in portrait on the rails and align against the end clamps .
Step 3 – Tighten the screws preassembled on the end clamps to fix the solar module onto the rails.
Step 4 – Slide the end caps onto the rail to secure the end clamps .
use the wire slot on the rail to tuck away any wires or cables (Fig. 1)

with the adjacent module 1 . Do not tighten the clamps yet.
Step 2 – Position the solar module 1
in portrait on the rails and align against the middle clamps .
Step 3 – Tighten the preassembled screws on the middle clamps to fix the solar module onto the rails.
Step 4 – Repeat steps 1 to 3 until the final solar module along the rails is installed.
