462 kWp Membrane Flat-Roof PV in Istanbul on ISOFLAT D13 V.3 Mounts
Completed module rows next to the rooflight domes
In brief
ISOTEC supplied the ISOFLAT D13 V.3 mounting system and a project-specific structural analysis for a 462 kWp solar plant on the flat membrane roof of a building in Arnavutköy, Istanbul. The plant has 840 modules of 550 Wp, laid out back to back in an east–west arrangement and fixed to the roof covering with IMC.
The project
Back-to-back rows on a long flat roof with rooflight domes
The plant sits on the flat, membrane-covered roof of a 19.50 m high building in Arnavutköy, Istanbul. The roof is long and wide; a line of rooflight domes runs along one edge, and the module rows continue past them to the far end of the roof without a break.
ISOFLAT D13 carries the modules back to back in an east–west layout at a tilt of 9.72°. On this roof 840 modules of 550 Wp were laid out in this arrangement. The installation photos from October 2024 show the rails and feet laid out first, then the module rows closing up. The modules are fixed to the roof covering with IMC membrane fixings, which are welded to the membrane with hot air.
ISOTEC prepared a project-specific structural report for the supporting system. It is based on a ground snow load of 0.75 kN/m² and a wind pressure of 0.80 kN/m², with the building height of 19.50 m taken into account. The report was reviewed and approved by the civil engineering department of a university.

FAQ
Which mounting system was used at this plant in Istanbul?
ISOTEC's east–west flat-roof system ISOFLAT D13 V.3. A total of 840 modules of 550 Wp are laid out back to back, giving 462 kWp.
How were the modules fixed to the roof?
The modules are fixed to the roof covering with IMC membrane fixings, which were welded to the membrane with hot air.
Which loads did the structural analysis assume?
The project-specific structural report is based on a ground snow load of 0.75 kN/m², a wind pressure of 0.80 kN/m² and a building height of 19.50 m.
What roof equipment is there?
A line of rooflight domes runs along one edge of the roof, and the module rows continue alongside it.
