Solar Show Africa: New PV mounting system for flat roofs

Aerodynamic system for north-facing solar systems

Pretoria, 20.1.2016 – At the Solar Show Africa, South African wholesaler Lumax Energy presents Renusol´s new ballasted flat-roof mounting system FS10-S and FS18-S for mounting north-facing photovoltaic panels. It requires few components and uses especially short rails, making the system price-efficient and quick to install. As it has little surface area exposed to the wind and is equipped with wind deflectors, minimal ballasting is required, making the new mounting system especially suited for commercial and agricultural buildings with lightweight roofs.

“Renusol is increasingly emphasizing simple mounting systems that can be installed very quickly and comfortably at the construction site”, explained Sven Künzel, Managing Director of Renusol. “For example, our 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.”

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 manoeuver on the construction site. The remaining system components also offer easy handling and storage – 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.
