2.1 SAFETY AND TRANSPORT
3 PLANNING
3.1 REQUIREMENTS
This document allows you to plan your Q.FLAT-G5 flat roof
system in conjunction with the Q CELLS ROOFTOP PLANNER.
Please contact your Q CELLS sales representative to use the
Q CELLS ROOFTOP PLANNER design program.
Installation location
Please note the following information regarding the installation
location:
•
Q CELLS solar modules have been tested for safe operation
in temperate climates in accordance with IEC 61215.
•
Q CELLS solar modules are not explosion-proof operating
equipment.
Ä
Do not operate solar modules near flammable gases or vapours
(gas containers, petrol stations).
Ä
Do not install solar modules in enclosed spaces.
Ä
Do not install solar modules in locations where backwater
can build up (e.g. flood zones).
Ä
Solar modules cannot be used as a substitute for standard
roof covers (for example, solar modules are not impermeable
to water).
Ä
Do not install solar modules in close proximity to air condi-
tioning systems.
Ä
Do not install solar modules at altitudes exceeding 4000 m
above sea level.
Ä
Do not allow chemical substances (e.g. oil, solvents, etc.) to
come into contact with parts of the module. Only substances
approved by Q CELLS may be used during assembly, operation
and maintenance.
Absence of shadowing
Optimum insolation is required for maximum energy output:
Ä
Position each solar module so that they face the sky on the
front.
Ä
Avoid shadowing (e.g. due to buildings, chimneys, trees).
Ä
Avoid partial shading (e.g. due to overhead lines, dirt, snow,
plants).
Application limits
The Q.FLAT-G5 is designed for the following applications:
Ä
Operating temperatures from –40 °C to +85 °C (–40 °F to
+185 °F).
Ä
Wind impact pressure to q
p
=1.0 kN/m² (according to DIN EN
1990), snow load on the roof to s
k
=2.0 kN/m² (according to
DIN EN 1990).
Module selection
•
Q.FLAT-G5 may only be installed with Q CELLS solar
modules with the dimensions 1670 mm × 1000 mm × 32 mm
(e.g. Q.PEAK-G4.1) or 1685 mm × 1000 mm × 32 mm (e.g.
Q.PEAK DUO-G5), including frame.
•
The latest version of the product data sheet is always decisive.
Ä
Refer to the product data sheet for detailed electrical char-
acteristics.
Ä
Only wire solar modules of the same type and power class
together.
Fuses and cable cross-sections
Ä
The design of the fuses, cable cross-sections and other
electrical operating equipment must comply with DIN VDE
0100-712 and be carried out by a suitably qualified profes-
sional electrician.
Series connection
Series connection of the solar modules is only permissible up to
the maximum system voltage specified in the current version of
the data sheet as amended.
Ä
Ensure that the system voltage is not exceeded under any
operating conditions.
Roof suitability and protection
Q CELLS assumes no liability for the general suitability or pro-
tection of the roof when using the Q.FLAT-G5 flat roof system.
NOTE
!
During the verification of slip resistance, a static friction coef-
ficient of
μ
= 0.50 is established for the Q.FLAT-G5.
Ä
If this is not achieved with the existing roof, please contact
Q CELLS to correct this for the planning phase.
Ä
Use the document “Determining the static friction coefficient”
to determine the static friction coefficient.
Ä
Please note that the supplied building protection mat can be
combined with the roof cover. An aluminium-clad building
protection mat requires a foil roof cladding in order to prevent
plasticizer migration and accelerated ageing.
Regarding bulging of the roofing foil under wind-suction loads
(ballooning effect):
•
in the absence of a sufficient bond between the roof foil and
the roof structure, low pressure in roof areas exposed to the
wind can cause bulges to form in the roofing foil. In extreme
cases, this can lead to movement of the Q.FLAT-G5 flat roof
system.
Ä
Appropriate on-site safety measures must be taken to prevent
this.
Ä
Make sure that a sufficiently large gap is retained between the
roof cladding and loaded ballast carriers if the roof surfaces
are uneven.
