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

by

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!

Static friction coefficient with AeroFix and AeroFlat

by
Static friction and spring scale

In the flat roof sector, aerodynamic mounting systems have evolved, especially for foil, bitumen, green and gravel roofs. The reason for this success is the simple assembly compared to other systems, as normally no roof penetrations have to be made and better load values are achieved through the aerodynamics. Instead, ballast is only applied depending on the project. In this context, the so-called static friction coefficient between the bracket and the roof cladding plays an important role in all aerodynamic systems on the market, for example in our IBC AeroFix and IBC AeroFlat systems, because it strongly influences the ballast. How this is determined exactly and what needs to be taken into account is explained in more detail below. (more…)

“Mounting systems” blog series part 8: design – when the visual appearance matters

by

When photovoltaics originated homeowners decided to use solar energy and install their own PV roof system with the conviction of sustainable and green power generation. Little attention was paid to the appearance or design of the PV system. However, thanks to continuously reduced prices of photovoltaic systems in recent years, a change has now occurred. PV systems should no longer only be sustainable and renewable, but should also be elegant in design and visually appealing. As a result, more and more products are being launched on the market for modules as well as mounting systems to meet this demand, such as the IBC TopFix 200 insertion system.(more…)

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

by

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…)
