Secure basis for high-yield solar power generation: The Duraklick SR mounting system is a lightweight, self-supporting flat-roof mounting system for large-scale photovoltaic systems on industrial and commercial buildings. The spoiler system in lightweight aluminum construction was specially developed to meet the requirements of large-scale rooftop systems. Due to the optimized airodynamics, ballasting can be reduced to a minimum. It impresses with its high quality and is quick and easy to install without roof penetration.
