Successful LGA approval for the roof-mounted system GehrTec® Top


Dornach n. Munich. The Landesgewerbeanstalt Bayern (LGA), a public-law corporation accredited for structural analysis and mechanical stability testing, has tested and certified the module mounting system GehrTec® Top in August 2012. The test report S-WUE 070466 confirms once again the high quality and mechanical stability of the GehrTec® system which is both internally-developed and selfmanufactured. Currently there are very few suppliers in the market that can prove such an LGA certification for their mounting systems. Moreover, with GehrTec® Top a high degree of pre-installation is possible and, due to the few system parts, results in extremely low material and labour costs and optimized profitability.

The installer appreciates the legal certainty provided by the LGA type test that the dimensioning of the mounting system design conforms to all relevant norms and regulations. In some public sector construction projects, mandatory and often timeintensive structural auditing requirements of the applied calculation methods are also no longer required, as the type testing releases the supervisory authorities from this requirement. With respect to the instructions publicized in May 2012 by the German Institute for Construction Technology (DIBt) for photovoltaic plants, this is a further step to adherence to the construction requirements (product and dimensioning regulations) and the defining of photovoltaic systems as engineered structures.

GehrTec® Top is a flexible, scalable roof-top installation system, suitable for a wide range of roof top types. All components “made in Germany” are of high quality aluminum and stainless steel (ISO standard). Thanks to its high load-bearing ability the GehrTec® Top fulfills the DIN 1055. Moreover the high quality system parts are distinguished by their high resistance to corrosion, guaranteeing an especially long life of the entire system design.
