Engineering Springs for
Solar & Renewable Energy
Manufactured for industrial applications according to customer specifications
We manufacture wire-formed springs, stamped and bent parts, and other types of technical springs as components for PV and solar systems. Based on drawings, samples, or specifications.
Advantages
Prototype production and various surface coatings to test fit and function.
Certified stainless steels and surface coatings for long-lasting outdoor applications
Ready to use
Assembly of components and custom packaging available upon request
We understand the challenges
facing the solar industry
Solar power systems are designed to last 25 years
exposed to extreme weather conditions, UV radiation, and cyclic mechanical loading. Even a
a small clip or a spring that, after five years,
If it breaks, it can result in immense maintenance costs.
We provide the security your components need
require.
We process highly resistant stainless spring steels
(e.g., 1.4310 or 1.4401), which are resistant to salt spray and permanently weather-resistant.
Our springs can withstand extreme wind and snow loads. They are designed for continuous tension and high fatigue strength.
We optimize springs for specific applications,
For example, for click systems that allow for tool-free and repeatable assembly.
Through process monitoring and comprehensive documentation, we safeguard your claims against end customers.
Areas of Application
Where our technical expertise in solar thermal energy and
photovoltaics makes a difference
We manufacture precision components for the key parts of your PV system, exactly according to
Your drawing, sample, or functional requirement.
Mounting Systems & Module Fastening
Ensure the mechanical stability of your equipment for decades to come.
Wire-formed springs, stamped and bent parts, and compression springs optimized for wind and snow loads, designed to securely hold PV modules in place on module mounts.
Specially shaped clips that drastically reduce installation time on the roof or at the installation site.
Fatigue-resistant springs for movable substructures that are subjected to daily mechanical load cycles.
Electrical Engineering & Energy Storage Systems
Reliable electrical connections and protection for sensitive electronics.
Highly Conductive Components for Inverters and Junction Boxes
Reliable electrical connection to the system ground for the mounting rails.
Spring elements for vibration-resistant connections to battery cells.
Protection & Safety

Precision Components for Management and Safety Systems
Precision springs for fuse holders and switchgear in DC applications.
Small Parts for Home Energy Management Systems and Smart Home Components
From Prototype to "
" Production Part
From prototype to mass production in record time. Have you developed a new mounting bracket? We can quickly produce samples for you or advise you on prototype manufacturing so you can test the spring force and fit in real-world conditions. This helps you minimize your risk before starting mass production.
The Sketch / Idea
Do you have an idea, a rough sketch, or a 2D/3D drawing for a new mount?? We review your functional requirements and advise you on the optimal design . Even at this stage, we take into account the installation situation, available space, and environmental conditions, in order to streamline the subsequent manufacturing process.
The Prototype
Before your part goes into production, we’ll quickly produce prototype parts or a small batch to verify its functionality.. This allows you to test spring force, holding force, and fit directly on the object. This minimizes your development risk, refines the geometry, and provides you with maximum assurance before the start of series production.
The Production Part
Once approval is granted, we will transition seamlessly to mass production. We process certified materials to ensure long-term stability through continuous process monitoring. Upon request, you can receive your components ready for assembly or in special packaging tailored to your logistics needs..
Technical Springs for the Solar Industry
Whether you already have a finished drawing or still need assistance with the design of your spring components:
We are your partner, providing guidance from the initial prototype all the way through to on-time mass production by us. Reduce your risk of complaints with springs that deliver on their promises.
We can quickly answer your questions by phone or email, or through the contact form. You can find the direct points of contact on the Contact page.

Questions and Answers: Technical Springs in the Solar Industry
What information do you need to provide a quote?
Ideally, a drawing (2D/3D) or a sample part. Additional information such as the installation situation, desired spring force, available space, quantity, and operating environment (e.g., outdoors, salty air) is also helpful.
Do you also manufacture prototypes or sample parts for PV components?
We provide you with detailed guidance on prototype development and, based on this, deliver samples or a small production run for functional validation before seamlessly transitioning to mass production.
What materials do you use for outdoor applications?
For photovoltaic applications, we process stainless spring steels such as 1.4310 or 1.4401, which are designed to withstand corrosion and weathering.
Can you design clips and wire-formed springs for click systems?
Yes. We design wire-formed springs and clips so that the assembly process and holding force are tailored to the application, with a focus on tool-free and error-free assembly.
Do you supply only individual parts, or do you also supply pre-assembled units?
Upon request, we also supply subassemblies and custom packaging to simplify your assembly and logistics processes.
How do you ensure documentation and process reliability?
Through process monitoring and comprehensive documentation, we ensure traceability, which is helpful in the event of a complaint.
