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 […]

Blackout: The Five True Solar Heroes That Power Through Outages

Published on 28. October 2025
When the lights go out it’s not only every second that counts, but every kilowatt hour too:  a sudden power cut can happen at any time—be it due to a storm or grid overload. Understandably, for many this is a worrying scenario. So it’s reassuring to know that a photovoltaic system can do more than […]

Blackout – when the grid is pushed to its limits

Published on 21. October 2025
Switching on the light, charging your cell phone, and even flushing the toilet—things that we all take for granted. But what happens when the power suddenly cuts out and the socket becomes a useless ornament from one moment to the next? In this article, we shine a light on the topic of blackouts.

Solar power in the Arctic Circle: the northernmost PV system in North America

Published on 16. October 2025
Producing PV electricity where the sun doesn’t rise for several weeks at a time and where the sea is frozen for around three quarters of the year? What may sound crazy at first is actually possible—not to mention lucrative—with state-of-the-art solar technology. But how? We reveal all in this Energy Story…
