24 hours of sun is possible.

Our vision: 24 hours of sun


We believe in a future in which we cover 100% of our global energy requirements from renewable sources: the world of 24 hours of sun.

We call this energy future 24 hours of sun. In this future, renewable energy will be intelligently and economically generated, stored, distributed and consumed with unprecedented efficiency. In this energy world, renewables are the most independent, effective and cheapest energy sources. This will make energy available in a sufficient quantity to everyone, anywhere and at any time. Solar energy plays a leading role in the mix of renewables that supply us with energy around the clock. 24 hours of sun will bring us:

We are obliged to ensure the world still holds a worthwhile future for our children. 24 hours of sun is the solution for an economically and ecologically sustainable energy supply for us and future generations.
The transformation of our energy supply and grid infrastructure will provide strong impetus for growth and with it many jobs worldwide. We will all profit from the technological innovations that will turn renewables into the cheapest form of energy production in the world.
24 hours of sun will liberate us from fossil fuels and energy imports. At the same time, it frees us from the vulnerability of a central energy system. In the world of 24 hours of sun, we will be able to choose where our energy comes from and, above all, we will all have access to clean energy.


The key lies in technologies and solutions that, step by step, allow renewable energy to be generated and stored ever more efficiently, as well as to be distributed and consumed intelligently and cost-effectively. We are working on this, day in day out, to drive the transition towards an energy future with 100% renewables with our technologies and energy solutions.

To achieve this, we at Fronius are focussing on the following three principles for every product, service or technological innovation relating to the generation, storage, distribution or consumption of renewable energy:

  • Reliability of supply: does the innovation ensure long-lasting, reliable operation?
  • System optimisation: does the innovation optimise performance in terms of efficiency or scope?
  • Future-proofing: does the innovation contribute towards fulfilling future demands today and can it be upgraded to accommodate further functions in the future?

Applying these principles guides our decision-making process in making energy from renewable sources more competitive with our technologies and energy solutions: step by step, until they become the most cost-effective forms of energy in the world and 24 hours of sun become a reality for us all.

We at Fronius know that we cannot achieve 24 hours of sun alone. This is why we are cooperating with other innovators who share our passion for this vision of a clean energy future. And we know it will take more than just technology: it will require people and companies who actively choose us and support us in our goal of a safe and clean energy supply. Only by working together can we make this visionary goal a reality for us all.
