User advice sheet: Use, maintenance and repairs
SMQ-F0-13-180724
Congratulations, you have become the proud owner of an EASY ROOF EVOLUTION system!
With EASY ROOF EVOLUTION you have chosen a practical, reliable and aesthetic solution for your roof
photovoltaic project.
For an optimal use of the system , please read and keep the following cleaning and maintenance instructions:
All photovoltaic systems must be regularly monitored and cleaned. To this end, your installer can provide you
with a maintenance contract. If you are interested please ask him for details.
All maintenance and repair operations on IRFTS products must be carried out by qualified technicians trained by
IRFTS. These operations require electrical and roofing skills.
System maintenance or repair operations must be carried out in compliance with work regulations and in
particular regulations for work at height. To avoid putting direct weight onto the modules, do not walk on them.
Putting weight on the clamps and fixing brackets is acceptable.
In the case of a maintenance or repair operation that requires the removal of a photovoltaic module, the
electric disconnection and reconnection procedure applicable for the replacement of a module must be adhered
to.
Photovoltaic field maintenance
At least once a month (before summer to optimise electricity production) as part of the roof maintenance:
The photovoltaic modules must be cleaned with a hosepipe (without using pressure or a concentrated
stream of water)
Visual inspection, spotting damage
Waterproofing check: check the condition of the different waterproofing elements, that the water runs
freely through the flashing channels. If necessary, clean the channels.
Check the wiring
Check the fixing points: check that all the screws and bolts are present and properly fixed in place
Electrical maintenance
If, once the real amount of sunshine has been taken into account, a measurable reduction in yearly production
from one year to the next is observed, the inverter and the individual modules should be checked to see if they
are working properly.
Module replacement
If the glass of the photovoltaic panel or the panel itself is damaged, please follow this procedure:
1. Disconnect the inverter (s) from the network by opening the AC circuit breaker located between the
inverter (s) and the meter.
2. Disconnect the photovoltaic field by opening the DC switch/breaker located between the modules and
the inverter. If the system is equipped with micro-inverters they automatically disconnect the
photovoltaic field after step 1.
3. Dismantle the parts of the assembly system in reverse installation order to gain access to the module’s
wiring. Never withdraw the connectors in the rain.
4. Assemble the new module in compliance with its installation instructions (see Installation instructions)
Reconnect the equipotential connection to the new installed module.
5. Check that the modules concerned are working properly:
a. Measure their open-circuit voltage range
b. Check the compatibility of this range with the inverter’s input range
6. Reconnect the photovoltaic field by closing the DC switch/breaker (except if there are micro-inverters),
then the AC circuit breaker.

a) Connect the ground wire directly to the PV
module.
Link the PV module directly to the grounding
wire using the holes provided by the
constructor underneath the module.
a) Method 1
Connect the ground wire to one middle bracket
(7) for two PV modules
It is possible to ground both the PV module and
the double mounting bracket (7) by using an
EASY GROUNDING (www.irfts.com)
one earthing part on every module
one earthing part every two modules
There are two ways of wiring the PV field
earth, depending on the regulations in force in

Technical definition de l'installation et Support
battens definition EASY ROOF
8)
19
The choice and sizing of the EASY ROOF system support battens is made according to the type and structure of the
roof frame destined to receive the integrated system. The EASY ROOF system can only be installed on roofs with
slopes ranging from 10° to 50°. The buildings must be enclosed (closed roofs).
Use the tables in the following pages to establish the dimensions of the support battens that you can use for the
assembly.
The number of fixing points per PV panel can vary between 4 or 6 depending on the battens that have been chosen
for the installation of the PV field and/or the installation zone (edge of roof, marine environment etc.)
The values set out the in the table below apply only to those geographic zones that correspond to 1 to 4 of the snow
and wind regulations French Standard NF EN 1991-1-4 and for an altitude of less than 900m. For zone 5 a technical
and feasibility study must be carried out on a case by case basis.
It is essential to adhere to the sizing instructions. A sizing software MY SOLAR PROJECT is available on the site IFRTS
(www.irfts.com).
For roofs with a continuous batten, an anti-abrasion underlay that is compliant with the DTU (Construction Unified
Codes of Practice) is mandatory
Please note that the guarantee will only apply if the installation has been carried out in compliance with the rules
provided in these instructions and in the different annexes to which they may refer.
For a PV field that is higher than 12m in the direction of the roof slope, horizontal deflectors must be placed (at right
angles to the slope) between the PV modules.
For PV fields of 15m and above in the direction of the roof slope, in addition to the required deflectors, the double
and single fixing brackets must be replaced by glazing stops that cover the whole length of the PV module with the
mandatory addition of blanking covers between the glazing stops (see Annexe 6 page 75).
MODULE COMPATIBILITY
The installer has to ensure that the PV module chosen for the installation is on the compatibility list drawn
up by IFRTS (www.irfts.com) and adapted to climatic loads.
If the EASY ROOF system is to be installed on a building by the sea or one used for intensive farming, it is up
to the companies installing the system to make sure that all of the parts used in the installation, in particular
the termination system, are compatible with either salt-spray exposure or an ammonia filled environment.
In particular, the modules must be validated according to French standards NF EN 61701 and NF EN 62716.
The assembly instructions of the photovoltaic module manufacturer must be respected. It is up to the
installer to check that the photovoltaic module manufacturer’s requirements are respected during the
mounting of the said module into the assembly system that is the subject of the present instructions.
TRAINING
IRFTS recommends and offers an “installer” training course, provided by itself or another company.
This training course covers the installation of the EASY ROOF system as well as all aspects relating to safety
(work at height, electrical safety).
A roof structure at ground level enables the different elements of the installation to be presented and allows
the participants to work under real-life conditions according to the technical regulations in force. It also
serves to highlight awareness of the dangers inherent to this profession and of the importance of following
safety regulations.
SAFETY INSTRUCTIONS
Before carrying out any work on a installation, appropriate safety measures for working at height must be
put in place such as, accident prevention measures using CPE or PPE for each worker.
INSTALLER QUALIFICATIONS
To become an EASY ROOF system installer you must be a professional with roofing and electricity expertise
corresponding to the French designations QUALIPV BAT and ELEC.

FIELD OF USE
Installation:
•Rural non-polluted, normal or heavy industrial or marine environments.
•On insulated or non-insulated buildings, exclusively on a cold roof
•Only in places with low or intermediate humidity, in a healthy environment.
•Use up to Seismic Zone 4 for Category IV buildings.
•Whole or partial roof installation.
•The length between the bottom of the PV field and the roof ridge must not be more than 12m
(discontinuous roofing).
PERFORMANCE IN DIFFICULT WEATHER CONDITIONS
•Thephotovoltaic panel structure does not contribute to the stability of the building
•Only the EASY ROOF system (with filling that retains its shape) is appropriate for wind zone 4 and for an
altitude of less than 900m for snow loads. The system is valid for normal to 1600 Pascal wind loads and
normal to 2400 Pascal snow loads.
•Moreover, it is the installer’s responsibility to ensure that the photovoltaic module used is appropriate
for the climate loads.
•Any modifications to loads for renovation projects must be studied by a specialist design office in
compliance with current calculation regulations. In any event, the solidity of the existing structure must
be tested by a certified testing body or by a specialist design office.
ELECTRICAL SAFETY OF THE PHOTOVOLTAIC FIELD
•The electrical standards in force must be complied with. In particular, in France, standards NF C15-100
and NF C-712 are mandatory
•The documentation supplied with the different modules makes it possible to confirm that they comply
with French standards EN 61 215 and EN 61 730 (guaranteed electric and thermal performances:
category A according to French standard NF EN 61 730 up to 1000 V DC).
•Some of the technical data sheets from module manufacturers mention that the characteristics of the
parts can be changed without prior notice. It is the installer’s responsibility to ensure that the panels
are always category A.
•The photovoltaic modules are equipped with detachable connectors, classed IP65 and category A.
The installer will ensure that all PV modules are of the same brand and the same reference.
•So as to guarantee the safety of the roof-integrated photovoltaic field, we recommend the use of PV
modules equipped with junction boxes that comply to standard CEI 62790:2014
•Bearing in mind the mention made in the technical data sheets, it is the installer’s responsibility to
make sure that the category of the equipment and the protection rating are A and IP65 respectively.
