Is the roof in good condition?
Do not change it and opt for



overlaid system

The GSE ON-ROOF SYSTEM is the quick and easy solution for fastening photovoltaic panels overlaid on the roof. Its revolutionary patented design has been developed in 2018 for an installation in total safety whilst maintaining the warranty of the current roof covering.

main advantages of
GSE On-roof system

Resistant and solid

This innovative solution enjoys extreme mechanical resistance.
• Tests on the studs have been conducted by CSTB (Scientific and Technical Centre for Building) on a traction of 1488 kg/stud (1489 daN) and shearing (slip) of 306 kg/stud (300 daN).
• It complies with the DTU implementation rules for roof covering components. Loads are transmitted directly onto the rafter. The standard fitting track has a wide span with just two studs on 5 m of track.
• Eurocode 8 climate resistance: The studs or hooks are compatible with all snow and wind areas up to the coast.
(France - Rule NV65/Eurocode 8,m Order of 22/10/10 amended).


This fitting system prevents rainwater from infiltrating under the tiles. The assembly is fully watertight; this has been validated by CTMNC (Technical Centre for Natural Building Materials) wind tunnel tests (Moby Dick 2).


2 studs, 2 plates for 100% of roofs!

The two 96mm and 136mm high studs coupled with an exclusive 40x40cm plate or a 50x60cm lead tile, allow for overlay fixing on 100% of roofs. It is compatible with framed photovoltaic panels of any size and with all roofing elements on the market. This innovative Made in France solution has been developed in line with GSE Intégration's own innovation and with Terreal's 30 years of expertise in lead tiles.
Innovative solutions have been developed for slates, flat tiles and tiles with highly-curved channels.

Easy to fit and extremely resistant:

Ideal for professionals seeking to simplify and optimise their installations in line with best practices!

The system can be fitted in portrait or landscape format without cross track and with a very limited number of parts:
• Just two studs for all roof coverings and fully watertight assembly. They exist in two sizes: H96/H136 mm.
• Single-profile aluminium tracks for wide span! They exist in five lengths: 2,10/2,40/3,15/3,58/4,15 m.
• Just one stud every two metres depending on the installation areas.
• Two fitting methods: Slate and flat tile/Flat roof tile, slightly and highly curved.
• Quick-fit brackets and aluminium fasteners round out the GSE ON-ROOF SYSTEM.
• Roof slope: identical to the stipulations of the manufacturer of the roofing.
• Materials: Stainless steel/Aluminium/PEHD/PVC/Lead.
• Warranty: Ten years.
