Default situation for continuous mounting rails
Please note that the module can bend under high loads and can strike the mounting rails. Ensure that the mounting rail
displays a sufficient stability and the fixing points are set with sufficient frequency to prevent the mounting rail from
bending. (tested with Heckert Solar rails and a support spacing of max. 1m)
Ensure that the maximum mechanical load is not exceeded, in particular while also taking into account the site-
dependent loads, e.g. wind and snow (DIN 1055-4/5).
Do not use any fixing material that might damage the module e.g. due to pointed, sharp or uneven structures. Please
note that the module bends under load and can strike the supporting surface/ mounting rails. Ensure that the connector
sockets and cables, when necessary, are not damaged or exert pressure on the cells.
The total snow load on the ground sk in kN/m² results from the respective snow load zone, the building site and the
ground height above sea level. The total wind load for the project site must be determined from the wind zone map,
which takes into account the site situation as well as wind zones. For buildings up to a height of 25 m, the total wind
load may be determined through a simplified procedure. Independent of building heights, the wind load is specified as
velocity pressure q in kN/m
