Varista mounting clip

The mounting clip is at the heart of our varista® substructure — an innovative connection solution made of durable plastic and a specially engineered stainless-steel nut, which ensures maximum stability, easy installation and precise positioning of the components. This is how a secure hold in the varista® mounting rail with effortless adjustment at the same time.

"We have already successfully completed numerous projects together with varista. The gorund-mount systems impress with high-quality substructures, precise planning and timely implementation. Professional project support and close coordination during planning and implementation ensure smooth implementation. varista is the right partner for demanding projects."
Gerhard Rabensteiner
Managing Director, KPV Solar GmbH
“The varista mounting system impressed us all round: high-quality materials, sophisticated construction and intelligent solutions — even for complex roof shapes. The blue mounting clip in particular saves significant time and makes handling significantly easier, without sacrificing safety or stability. Even under heavy snow loads and demanding conditions, the system proves its strength through flexible and tailor-made solutions — absolutely reliable.”
Martin Reifensteiner
Product Manager, Schrack Technik GmbH
“We have been using Varista's mounting systems for several years. Our guys on the construction site are still excited about it. It's really easy to use, everything fits, nothing wobbles. Especially with a tight schedule, this is worth its weight in gold. But that's not all: in addition to the sophisticated assembly systems, the close and excellent collaboration with the Varista team, which has grown over the years, was and is also a real highlight for us. Competent, available, communicating on equal footing and always solution-oriented with the customer — that is what makes working in partnership for us. Thanks for that!”

Flat roof PV in Berlin with Aero Rail Twice

In Berlin, a photovoltaic system with an output of 615 kWp was successfully implemented using our Aero Rail Twice system. The aerodynamic assembly system impressed with its simple and quick installation, which was particularly efficient thanks to pre-assembled components and clear system logic. The low ballast and the sophisticated construction make the Aero Rail Twice the ideal solution for flat roofs with limited load capacity. The result: a stable, safe and durable PV substructure that meets the highest standards of efficiency and ease of installation.

WOW! We designed and produced the substructure for the third-largest solar thermal system in Germany!

We supply our customer with an assembly system specially developed for the SPX5 tube collector. We are thus making an important contribution to the energy revolution and supporting the expansion of sustainable energy sources. The construction site in Stralsund began in October. Our team's work on site will be completed by the end of April. From mid-2025, the solar thermal plant is to be put into operation and produce around eleven gigawatt hours of renewable, CO2-free heat every year.
