For the Photovoltaik special edition „Flachdach-Spezial“, our CTO, Christian Ganahl, was interviewed. He explains how PV installations on flat roofs can be safely planned without damaging the building and while withstanding high wind loads. Here's a brief overview of the article “We Can Plan More Complexly.”
The focus is on the responsibility of planners and craftsmen to ensure that the photovoltaic system does not cause any damage. Christian Ganahl emphasizes the legal consequences if the right components and correct construction execution are not considered. Possible repercussions range from civil claims to criminal liability.
A particular emphasis is placed on supporting installers to prevent damage. This starts with product safety and extends to planning reliability and safety for the building. The CE marking for the system plays a crucial role in providing protection against recourse claims.
Safety through standards and CE marking:
As there is no harmonised standard for photovoltaic racking solutions in Europe, Christian Ganahl refers to EN 1090. Adhering to these standards and obtaining the CE marking is crucial to protect against recourse claims.
Product safety in detail:
The article provides insight into ensuring product safety at the component and system levels. It introduces computational proofs and component testing to ensure compliance with standards. The Finite Element Method (FEM) is explained as a software solution for performing static optimizations.
