We support


The solar industry holds a major key to solving one of the most pressing challenges of our time: Fighting climate change and achieving the transition to green and sustainable energy. That’s why we support solar and everything it stands for. As one of the leading manufacturers of solar mounting systems, we are proud to directly contribute to the green energy transition. Over 55 GWp of solar power have been installed on our systems worldwide. This means we are currently helping to save around 31.4 million tons of CO₂ per year.

We also believe that a growing solar industry is a tide that lifts all boats – customers, investors, competitors, humanity, the environment, and ourselves. And that economic success and sustainability must go hand in hand if we are to achieve lasting change. Balancing out these aspects is key for our clients as well as for our own operations. And it is the basis of our ambitious CSR policy that we have implemented and are constantly improving throughout our company.

Enabling the green energy transition every day.

We work hard to make the world a fairer, cleaner, and more sustainable place to live, but we’ve never actually articulated our goals, actions, or the impact we have as a business. Until now.

It’s taken us months to compile our first-ever CSR report, and we’re so proud to finally be able to share it with you. Inside, you’ll find our honest, in-depth account of 2023 from various environmental, social, and governance-related perspectives.

We’ll be releasing updated CSR reports annually from now on – but, for now, feel free to grab your copy of the original.

It’s hard to make progress on something you neither track nor measure, so we’re proud to have formalized a set of goals designed to guide our efforts in reducing our carbon and ecological footprints, conserving and prolonging resources, and embracing practices that contribute to a cleaner, healthier planet.

Over time, and depending on the progress we make, these goals will continually evolve. But, for now, they are:


  • >50% recycled packaging / single-material packaging / alternative packaging materials
  • >95% recyclable material at the end of the lifecycle of our products


  • 100% monitored supply chain (Tier 1)
  • >50% recycled materials in our products
  • Reduction of our products’ CO2 footprints by decreasing their power-to-weight ratios (kg of material per MW of installed capacity) by 5% annually


  • Achieve 100% coverage of the power supply for administrative workstations from renewable or green energy sources at Schletter locations


A Brighter Future.

Outstanding quality is and always has been an integral part of our sustainability approach. Our mounting systems are built to last. They are known in the industry for their advanced engineering and exceptional durability.

Our definition of quality goes well beyond producing the best possible product for its designated task. It also means using the resources we need to produce our products in the most efficient way possible. This is an attitude that is deeply engrained in Schletter’s DNA.

Our uncompromising commitment to quality is reflected in highest engineering and manufacturing standards. We strive to hit a „zero-defect target“ with all our products. We have backed up this target by strict and clearly defined processes and preventive risk-management practices throughout our own production and supply chain. These include the guideline for structural components, kits for aluminum structures (EN 1090-1, EN 1090-2 and EN 1090-3), and the Machinery Directive (2006/42/EC). And we are conducting constant training and vetting to ensure that these high standards are met.

We support

sustainable development goals.

As one of the leading solar mounting companies worldwide, we are contributing to several gigawatts of solar projects every year. But promoting clean, renewable energy is only one aspect of sustainability. There are many more areas where we need to act if we want to secure a peaceful and prosperous future for our planet.

The United Nations have defined these areas of action in the 2030 Agenda for Sustainable Development, defining 17 Sustainable Development Goals (SDGs). Asking ourselves what impact we can make as a company, we have committed ourselves to 12 specific SDGs.

Zero Hunger
