Pflaum roof panels turn the roof into a solar power plant
The roof as a solar power plant
The European Union has set itself the goal of becoming climate neutral by 2050. As part of its Green Deal legislation, the EU Commission wants to create increasingly sustainable energy systems. Net greenhouse gas emissions are to be reduced by at least 55 percent by 2030 and renewable energy generation capacity is to be expanded to 1,236 GW. A so-called "solar obligation", i.e. a legally binding EU obligation to install solar roofs, is accordingly under consideration.Resulting requirements for today's roof solutions
Efficient installation of photovoltaic modules is part of any planning for these reasons, but also for economic reasons. With rising energy costs, the solar power produced on the roof is integrated into the building and its utilisation concept and firmly planned as an independent, cost-effective energy supply - just like a lightweight, highly insulating roof covering.
Pflaum panels are the first choice for economical roofing due to their high load-bearing capacity, the best possible air and water tightness and perfect thermal insulation. The insulating roof elements can bridge spans of up to 6 m unsupported and achieve the best U-values for ideal thermal insulation in thicknesses of up to 140mm. With the 60µm Hairexcel® coating applied at the factory and the optimised joint geometry, Pflaum roof panels have proven their worth on countless roofs in Austria and Europe over the long term.
Solutions for the installation of photovoltaic modules
Due to the increasing demand, we have decided to offer our customers several options for mounting and to include the most common systems in the approval for our panels. The previous fastening via a rail in the longitudinal joint has now been supplemented by the most common fastening systems on the market:
- Schletter SingleFix V
- Schletter ClampFit
- K2 BasicRail
- Novotegra C24
- Novotegra C47.
Requirements for the coating
The covering of the actual roof surface by the PV modules prevents the usual cleaning effects caused by rain and wind. Thus, leaves, branches and other dirt can collect under the solar panels after only a short time and lead to an increased corrosive load. Furthermore, the corrosion protection system is exposed to additional stress through installation and maintenance of the solar system. The IFBS guideline PA10 (solar technology in lightweight metal construction) requires a thickness of the organic coating of at least 45 µm for metal roofs under solar systems. With Hairexcel® we offer a robust and corrosion-resistant coating system with 60µm that is adapted to the application.
