Renusol introduces new flat-roof PV mounting system

German solar giant, Renusol has introduced its new ballasted flat-roof mounting system FS10-S and FS18-S for mounting south-facing photovoltaic panels.

The new Aerodynamic system requires few components and uses especially short rails, making the system cost effective and quick to install.

The solar system has little surface area exposed to the wind and is further equipped with wind deflectors, therefore, minimal ballasting is required, making the new mounting system especially suited for commercial and agricultural buildings with lightweight roofs.

According to Renusol’s Managing Director, Sven Künzel, Renusol is increasingly emphasizing simple mounting systems that are easy to install at the construction site.

He says that their product developers have opted for an innovative screw joint that works without a nut, meaning that fewer movements are needed. Since the rails are delivered pre-punched, there is also no need to take cumbersome measurements on site, which decreases installation errors, thus added efficiency.

All standard framed solar modules can be mounted with the new system. The FS10-S system mounts PV modules at a 10 degree angle, while the FS18-S mounts at an 18 degree angle. Short rails with lengths of 1.38 m and 1.73 m are used with the FS10-S and FS18-S, respectively. Both sizes are easy to transport and maneuver on the construction site.

The remaining system components also come with benefits such as easy handling and storage which is an advantage for wholesale customers. The short rails are joined with connectors, making it possible to compensate for unevenness in the roof. In addition, slots in the rail connectors compensate for temperature expansions, which could otherwise lead the PV system to shift on the roof.

“Our customers also really appreciate that solar modules can be mounted up to half a meter from the edge of the roof. This makes it possible to install more modules on the roof and deliver a maximum power potential”, reports Marko Balen, Product Manager at Renusol.

The new mounting system is suited for bitumen, concrete, foil and gravel roofs. There is no need to penetrate the roof membrane in order to safely fix the system on the roof. Instead, pavers or concrete slabs are placed in the channels of the wind deflectors. Renusol offers a ten-year product warranty.
The system will be available beginning in February and will be presented at Ecobuild in London from 8th to 10th of March 2016.
