7 Mounting specifications

Always ensure that the mounting structure is earthed

(R ≤ 10Ω).

Leave a minimum distance of 5mm between modules

when mounting. This prevents mechanical tension

due to thermal expansion of the glass.

Leave a distance of at least 4cm between the back

side of the modules and the underlying surface, to

ensure the rear ventilation of the module.

Safety glass regulations

The product Elegante is a photovoltaic composite

safety glass (PV-VSG), marked with the code Z-70.3-

258 for the general architectural license (in Germany

"allgemeine bauaufsichtliche Zulassung - abZ"). The

module is a laminated safety glass (VSG) and should

therefore be used as a construction product.

In case of uncertainty regarding the mounting and

Linearly supported modules

Most of the architectural applications foreseen for this

product, e.g. carports or verandas, take reference to

mounting types in which the modules are supported

on at least two opposite sides through a continuous

line. Depending on their inclination against the per-

pendicular, they are divided into overhead glazing

(inclination > 10°) or vertical glazing (inclination ≤10°)

Figure 7A

Elegante Modules are licensed for both kinds of in-

stallation.

Mounting depth:

In case of an all-round linear support (e.g. in a frame)

the mounting depth must be at least 10mm. In the

case of two or three-sided linear support, the moun-

ting depth must be at least 15mm.

Deflection:

The assembly must be carried out in such a way that

the deflection of the module is not more than 1/100.

load, the linear support must ensure that the glass

safely remains in the support for both types of load.

No contact between glass and hard materials (e.g.

metal, wood) may occur under load and temperature

effects.

For distance between supports higher than 1.20 m

there is an increased risk that the glass will leave the

bearing in the event of a break.

Therefore, modules with a linear support along the

short side of the Elegante module, where the span

is higher than 1.20m, must be placed on all sides in a

linear support.

Drilling and cut-outs in the modules are not permitted.

The free edge of the module, parallel and perpendicu-

lar to the bearing, can be at most 30% of the support

length, but in any case not more than 300mm.

Overhead glazing:

In case of overhead glazing we recommend that the

surface of the modules is inclined at an angle of at

least 5°, so that precipitation can drain off supporting

the modules self-cleaning.

Elegante Modules linearly supported on the long sides,

can bear pressure loads till 7500 Pa and soak loads

till 5400 Pa, according to IEC 61215 (Crystalline silicon

terrestrial photovoltaic (PV) modules – Design qua-

lification and type approval), without compromising

the functional capabilty of the PV module.

7 .3

The technical rules for the dimensioning and execution

of point-mounted fastening types apply:

The point holders must be made of stainless steel with

at least a corrosion resistance class II.

The assembly must be designed in such a way that

the modules can be installed with consideration of

structural tolerances and that the glass cannot come

in contact with other hard components (e.g. metal)

under operating conditions (load, temperature, inflec-

tion of load bearing construction).

The free edge of the glass must not be more than

300 mm and at least 80mm.
