“From sunlight to energy” is an interesting and impressive way to produce renewable energy and to sustainably create and provide regular energy resources� For this reason, we at CWF, decided to make our contribution with the products and services of our company�

We are an established and dynamic company that offers a patented, high-quality carrier system for open-field photovoltaic installations�

Based on long-standing experience, we have eveloped carrier systems that are especially adapted to the requirements of open-field photovoltaic installations� Our aim is always to design a bearing, multi-adjustable and easy-to-install carrier system� We have made it - down to the last detail!

More than 2,0 gigawatt of carrier system for open-field photovoltaic installations worldwide are evidence of customer satisfaction and our ability to adapt our system to the market requirements�

Our services include:• Customized consulting and planning (structural analysis, trial pile driving, etc�)• Delivery and assembly of our carrier system• Module assembly

Vario Carrier system The patented CWF Vario angle-adjustment system

Highly flexible and precise angle adjustment

High flexibility on adaption to the compound

With our patented, multi- statically tested Vario angle-adjustment system, both S and C mounting piles can be chosen�The angle-adjustment system is fixed with only 6 bolts�

Our cross beams are individually adapted to each module layout� The advantage here is that the loads are distributed evenly across the entire frame design� Besides, it is also possible to further stabilize the cross beams to avoid excessive vibrations in the case of weather storms� The system is suitable for both framed and frameless modules�

For the entire system we only use high quality, weather-resistant and durable materials and components�

We at CWF want to leave nothing to chance as we want to make sure that your outdoor system withstands the forces of nature for at least 20 years�

We will be pleased to offer you advice and support to any further question about our system�
