Dome Solar, a specialist in photovoltaic mounting for large roofs, stands out from other photovoltaic installers due to its innovative heat-welded systems for flat roofs.

The advantage of these systems is that they allow photovoltaic panels to be mounted on flat roofs without ballasting.

There are two heat-welding systems depending on the type of membrane:

Each of them requires the intervention of a professional weatherproofer.

For a bitumen flat roof

The system is comprised of a set of rails: 1 rail and 2 retaining strips that are pre-mounted on the rail using 2 flanges.

The 4 installation steps are:

  1. Grid marked on the roof using a string or a laser based on the plans provided by Dome Solar;
  2. Marking in crayon of the precise location of the rails;
  3. The shiny surface of the membrane is heated so that the slate flakes melt down and penetrate into the bitumen;
  4. Positioning of the rail and flame welding of the two retaining strips.

These 4 steps are a mandatory protocol for the correct installation of Roof-Solar Bitumen and Roof-Solar Tilted Bitumen systems.

For a PVC or TPO synthetic flat roof

The set of rails is hot air welded.

The 4 installation steps are:

  1. Grid marked on the roof using a string or a laser based on the plans provided by Dome Solar;
  2. Marking in crayon of the precise location of the rails;
  3. Positioning of the rail and hot air welding of the two retaining strips;
  4. Tack welding of reinforcing patches in the corner of the rails.

These 4 steps are a mandatory protocol for the correct installation of Roof-Solar PVC, Roof-Solar Tilted PVC, Roof-Solar TPO and Roof-Solar Tilted TPO mounting systems.

Our photovoltaic mounting systems (bitumen, PVC and TPO) for large flat roofs enable your photovoltaic panels to be installed with a portrait or landscape orientation.

This technique, which does not require any ballasting, has the advantage of limiting the weight to be borne by your roof.
