3 novotegra for flat roof

The contents of this installation manual describe the installation of the substructure on roofs with sheet or

bitumen waterproofing, with or without gravel respectively substratum.

Depending on the roof seal material, separation and/or protection membranes may need to be added

between the roof seal and the substructure. This must be agreed upon directly between the company

installing the PV system, the building owner and the specialist roof sealing company.

The substructure is installed without penetrating the roof. The PV system is secured against wind suction

by providing ballast (e.g. suitable stones), based on the results of the wind tunnel tests for the system. The

required ballast is determined by BayWa r.e. Solar Energy Systems GmbH based on the project data

provided by the installation company. The ballast applies to the planned system; on-site deviations from

planning may lead to different results.

Protection against system sliding is verified based on a coefficient of friction of µ = 0.5. This value must be

checked by the installation company prior to installation. If the coefficient of friction is determined by the

installation company in advance, protection can be verified during planning using the determined value.

The system must be secured on site to prevent it from "creeping" due to expansion caused by temperature.

This can be achieved by installing suitable stop points on the roof surface or by anchoring to the parapet,

for example. The connection points on the building and building parts must be able to bear the forces

exerted.

General conditions to be observed in accordance with the wind tunnel test results:

Roof incline 0 – 5 degrees

Flat roofs with and without parapet

Distance from system to roof edge (without parapet) = 0.50 m

Distance from system to parapet (inside edge) = 0.50 m

Module width = min. 0,92 m; max. 1,08 m

Module length = max. 2,08 m

Angle of installation (fixed) = 13°

Distance between rows = 1.30 – 2.40 m (closed II) respectively 2.15 – 2.40 m (East-West II)

The installation system is designed for loads of up to 2.4 kN/m² (2,400 Pa). The modules are clamped on

the short frame side or, alternatively, on the long frame side in the corners (clamp surface 11 x 52 mm).

This requires approval from the module manufacturer for clamping on the short frame side or on the corner

of the long frame side. Any drainage openings on the module frame may not be blocked. This also applies

to the features provided for this purpose on the support components.

Subjects excepted. Illustrations are exemplary and may vary from the original.
