“Energy communities are here to stay”

Published on 27. January 2026
The PV system on the roof generates more electricity than is needed. The son studies 250 km away and pays high electricity bills. How convenient it would be to share your own energy! What was once unthinkable is now easily possible thanks to community energy. In this interview, energy expert and co-founder of the Fronius […]

What is the best orientation for solar panels?

Published on 20. December 2025
“Look to the south!” is always the guiding principle when installing solar modules. Or is it? It is true that south-facing solar panels are the most productive for generating solar power in the northern hemisphere, but it’s not the only option. In this blog you will learn all about the best orientation for solar panels, […]

Photovoltaics in winter—is it worth it? Facts & tips

Published on 12. December 2025
Summer and sun go hand in hand with solar power, but what happens in winter? PV systems are also reliable electricity generators in the winter months, albeit with lower yields because the sun is lower and the days are shorter. However, contrary to popular belief, cold and snow can actually have a positive effect on […]

The right battery for your PV system

Published on 27. November 2025
You can already use the PV electricity you generate during the day, but what about at night or during power outages? There are several aspects you need to consider for round-the-clock availability: not only the number of PV modules and type of inverter, but also what battery capacity would be the most economically sensible. The […]

Arc detection: why today’s PV systems are safer than ever

Published on 18. November 2025
Photovoltaic systems are considered safe—and with good reason. However, one danger is frequently underestimated: electric arcs that occur directly on the solar modules. These can cause fires that are tough to locate and difficult to fight. And this is exactly where AFCI technology comes into play: it detects arcs early on, thereby helping to minimize […]

Shade encroaching on PV systems—is it a problem of the past?

Published on 30. October 2025
More sun equals more solar power. Anyone planning their own PV system on the roof should look into the best conditions for their installation, to make sure the system works perfectly and generates optimum yields. The shading of solar modules continues to be one of the main factors preventing this, although smart developments on the […]
