GehrTec® Top

The flexible rooftop installation system for photovoltaic modules

The GehrTec® Top is an arbitrarily scalable system for rooftop mounting of framed and frameless solar modules on various roofs.

Your advantage

Optimal economy
The solar modules can be fixed quickly and flexibly by a 4 point clamp. The system enables a high degree of pre-fabrication and, due to the few system parts, results in extremely low material costs.

Highest quality
All components “made in Germany” are of high quality aluminium or stainless steel (ISO standard). Thanks to its high
load-bearing ability the GehrTec® Top fulfils the requirements of DIN 1055 and has received the “LGA-tested Quality” certificate from TÜV Rheinland.

Long life cycle
The high quality system parts, high resistance to corrosion and the extensively tested system design guarantee particularly long operational reliability.

Flexible installation
The unique profiled rail system enables flexible installation of framed and frameless solar modules. Each groove allows for screwing in nuts and bolts at any point.

Competent service
Design software for configuration and calculation is available.
