Sabine, Victoria who will be next? The next storm is as certain as the sunrise

In recent years a series of storms have swept across Europe. The list comprises some prominent storms in Germany like hurricane Niklas (2015), storm Xavier (2017), hurricane Friederike (2018), hurricane Sabine, and storm Victoria (both in 2020). During the last hurricane named Sabine, winds reached speeds of up to 177 km/h. Even in the lowlands, speeds of around 150 km/h could still be measured. This is a good enough reason for us to take a closer look at the calculation of PV systems. Because one thing is for certain – there will be more hurricanes on the way!


“Mounting systems” blog series part 7: Flat roof – safety – How many guardian angels have we already used?

Flat roofs are still of high relevance when it comes to the installation of PV systems. As already explained in previews articles of this blog series, the usage of roofs will change from not-used to used as soon as a PV system is installed. This results in a potential danger that previously safe work paths are now blocked. Therefore, the risk analysis has changed which particularly effects necessary work on roofs. In this sense, it may happen that paths for roof work, for example for the maintenance and servicing of water pipes or climate or ventilation systems which are now within  fall hazard areas. In such cases, a safe working condition within this area is important. System operators as well as designated companies are in charge of the responsibility to create a risk analysis.(more…)

The profile that came in from the cold

Right into the freezer and back. Well – with  an area of 30 square meters the freezer in this case is slightly bigger than the usual household devices. We are referring to a special test that we have performed on our mounting systems. We wanted to know the following: Will temperatures of  minus 20 degrees harm the rails and modules and can major icing cause frost damage? (more…)

“Mounting systems” blog series part 6: Flat roof heat insulation – How much of a burden can it handle?

Flat roofs are particularly well suited for the installation of a PV system – especially when a large PV system should be placed on the roof. More and more flat roofs are being equipped with PV systems; in the case of commercial business, they are usually for self-consumption. We have already discussed the installation of PV systems on flat roofs in part 4 of this blog series. Today’s article is all about heat insulation on these roofs and what areas require special attention. (more…)

“Mounting systems” blog series part 5: What else experts should know

It is important for the solar energy system to be securely fixed to the roof of all installations – and every roof has its own specific requirements. I would like to take the opportunity with this and other blog entries on the subject of “mounting systems” to present the typical mounting options to operators and installers for the most frequent roof types and give them recommendations. Today our topic is practical tips. (mehr…)
