On the path to energy self-sufficiency

Rising energy prices show just how important it is to become self-sufficient. To achieve this, the separate energy sectors of electricity, heating, cooling and mobility need to be considered from a holistic point of view.

Our goal is to achieve 24 hours of sun. Specifically, this means generating, storing, distributing and consuming energy from solar power cost-efficiently and intelligently. Solutions that optimally bring together the different energy sectors are essential to this. The ‘Energy sector integration’ is mapped at Fronius via the ‘Fronius energy flow management’. 

The following example illustrates why energy sector integration is so important. 

A 9 kWp photovoltaic system generates approximately 9,000 kWh of electricity per year. A self-consumption1 rate of 36% results in 5,800 kWh of excess current per year. This can be fed into the grid for a low price, equivalent to driving approximately 34,000 km in an electric vehicle (e-Golf) or generating 102,000 liters of hot water (Δ 50°C).
