Fronius expertise Your reliable partner for high-performance photovoltaics

Our expertise

The Fronius vision of 24 hours of sun represents a world in which 100 percent of our energy is obtained from renewable resources. Humanity’s daily energy needs will be met with clean electricity that is available to anyone, anywhere, at anytime. Solar energy plays a key role in this future world. To make this vision a reality, we must be able to generate, store, distribute and consume renewable energy efficiently and intelligently.

Many of the technologies and solutions required to achieve this are already available to us today. Others are in development or awaiting discovery. We are guided in our quest by the universal requirements that every cost-effective energy solution must meet: reliability of supply, system optimization and a future-proof design. Reliable energy supply means ensuring a stable and predictable supply of electrical energy, perfectly matching demand. Having electricity available when it is needed is the most important factor. System optimization means constantly improving energy solutions. The aim is to achieve the highest possible level of system efficiency, as our energy must remain affordable. Future-proof means energy solutions that are durable and flexible throughout their entire service lives. This allows them to adapt to changing technical requirements. This is the only way to secure your energy investment over the long term. Based on these three criteria, we develop reliable, cost-effective and sustainable energy solutions for today and tomorrow. Detailed information can be found on the following pages.

Reliability of supply

Regardless of the source, a reliable energy supply means electricity is always available, wherever it’s needed. Several things are necessary to make this possible, including a quality product, technical support and monitoring. Find out what Fronius is doing to ensure a reliable energy supply for today and beyond.


Our world is changing rapidly and with it, our energy supply. For long-term energy investments, such as PV systems that have a lifetime of several decades or a long payback period, this represents a major challenge. If conditions or infrastructure suddenly change, this may jeopardize the success of an investment. Therefore it’s important that energy solutions are future-proof. This means designing flexible, intelligent systems that can easily adapt to new requirements. Find out what Fronius does to secure your investment for the future.
