Your solid foundation for large-scale projects

Mounting systems – the foundation of every photovoltaic installation

For over 20 years, we have been implementing photovoltaic systems across a wide range of applications. Our mounting systems for rooftops, open fields, façades, and carports combine proven technology with high reliability and long-lasting durability.

Proven reliability

Design according to Eurocode
DEKRA-certified according to ISO 9001:2015
Up to 20-year warranty with verification in K2 Base and documentation in the K2 DocuApp

Affordable

Universal components for quick and easy assembly: minimizing time and labor costs
Low material usage for easier handling

Optimization of PV Performance

Our planning experts maximize the potential of every surface – for highest energy yield and maximum efficiency
Digital tools for precise design calculations and layout optimization

Experience & Local Support

With experienced professionals in over 40 countries and state-of-the-art digital tools, we ensure technical precision and customized solutions throughout the entire project duration.

Sustainability key figures at a glance

PV systems fitted with K2 mounting systems generate 126 GWh per day worldwide (as of May 2026) – equivalent to around 12 coal-fired power stations¹
Over 85 per cent of K2 products are manufactured in the EU²
Average carbon footprint of 4.5 tonnes of CO₂ per tonne for the aluminium used in the products (aluminium bolts)³ – lower than the European and global averages⁴

¹ Simplified calculation example based on assumptions: A 600 MW coal-fired power plant operating at full capacity (24 h*600 MW) generates 14.4 GWh per day; at 70% capacity utilization, it generates 10.08 GWh per day. Consequently, 126 GWh/day mathematically corresponds to roughly 12.5 coal-fired power plants.
