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.
