We put special attention on highest quality:
From the planning to the completion of your PV system
Our clients and partners appreciate the quality of the consultation and of the planning, up to a complete fitted delivery and assembly.
You can be sure that Grammer Solar GmbH as a leading system integrator, offers only selected and certified components of high quality.
Our modules have only positive power tolerances and always an individual measurement verification. Our focus is on modules, manufactured in Germany, with longtime guarantees on which you can rely when the worst happens. Leading modules from Asia which have the same characteristics as the German modules are also part of our program.
Our cross bar assembly system, developed by ourselves, is statically proved and consists of stainless steel or aluminium. Our cross bar assembly system ensures a good rear ventilation of the modules, which guarantees high yield. This is important because cooler modules provide higher performance.
Together with the optimal designed interverters, a sustainable high yield is guaranteed.
Al components and services of Grammer Solar GmbH correspond to highest quality standards, so that your PV system can generate permanently high yields.
