5.4.1 Roof mount
1. When installing a module on a roof or
building, ensure that it is securely and
cannot fall as a result of wind or snow
loads.
2. Provide adequate ventilation under a
module for cooling (5cm minimum air
space between module and mounting
surface).
3. The module is in a minimum fire resistance
rating of Class C, and the fire rating of this
module is valid only when mounted in the
manner specified in the mechanical
mounting instructions.
4. When installing module on a roof, ensure
that the roof construction is suitable. In
addition, any roof penetration required to
mount the module must be properly sealed
to prevent leaks.
5. In some cases, a special support frame
may be necessary.
6. The roof installation of solar modules may
affect the fireproofing of the house
construction. This module has a Class C
Fire Rating and must be installed over a
roof which is with appropriate fire
resistance.
