Photovoltaic Systems. Which One to Mount? It Depends On The Roof!

Photovoltaic systems. Considering that every roof is different, before installing a mounting system it is always advisable to consult an expert. It is in fact important to take particular account of static requirements.

Pitched roof frameworks.

First, you need to determine the position of the hook according to the project drawing.

In the fixing points of the hook you have to remove or lift the tiles, so that you can place the hook without putting pressure on the tile.
Adjust the hook in height and laterally in order to position it in the middle of the ondulations of the roof.
Fix the profile for each panels row (using screws and nuts)
In order to connect more mounting rails in series you can choose several types of connections (i.e. connector plates, …)

Hereafter, according to the kind of panels used you have to position the sliding block swivel on the upper profile, pushing it till the click. You can fix the end clamp in the sliding block swivel using a screw. (see which one)

NB: solar panels can be framed or frameless.

Pitched roof frameworks: the crossrail system.

A particular kind of installation is the crossrail system. When and why using it?

To mount frameless panels
The structure is much more stable

NB: you have to follow the mounting instructions of the solar panels producer.

Flat roof frameworks for trapezoidal metal sheet.

The installation of this kind of structure is carried out in 2 steps:

LOWER FIXING SYSTEM:

– Fix the triangles to the supporting structure

– Position a cup head square neck bolt in the upper profile (discover the screw)

– Hereafter, position the mounting plate on the threads in order to clamp the connection with a nut with flange and serration. (see which one)

NB: alternatively you can position the sliding block swivel in the profile. Hereafter, using a mounting plate fix the profile to the upper support with a screw (see which one).

UPPER FIXING SYSTEM:

– Fix the supporting structures for the solar panels to the tringle. How to do it? Place the screw in the lower profile of the supporting structure, leaving the threads visible. (see which screw)

– Position the mounting plate on the threads

– Clamp them using a nut with flange and serration (see which one)
