Roofs, loads and the correct mounting system

The AeroFix base rail G2 Eco

I will never forget my father´s face when my sister-in-law walked across his newly laid parquet flooring with spiked heels on …This funny example reminds me of, how “not so funny” and also how important sufficient area is for the distribution of relative loads. Because the same situation also applies to PV systems on flat roofs as in these situations, heavy loads can play a role, too. Either caused by snow loads, e.g. in Scandinavia or in the Alps, or by high ballasting weight. As a Certified Surveyor for Photovoltaic Systems, I see more and more cases where installers are confronted with building insurance claims for damaged roof coverings caused by heavy loads. In the case of a commercial sized roof, the resulting claims against the installer can easily get up to a six-digit number of value. (more…)

Static friction coefficient with AeroFix and AeroFlat

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 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…)

IBC SOLAR partners with Preising for more safety on roofs

Safety on roofs is a major issue throughout Europe. There are different regulations and guidelines that cause a lot of uncertainty. Preising and IBC SOLAR now collaborate offering their customers a unique safety system for the maintenance of PV systems on the flat roof: a fall protection device, the AeroFix Latch (more…)

Uppsala is Sweden’s solar stronghold

The solar boom has reached Sweden and Uppsala is at the top. The town is in forefront when it comes to number of PV installations. Uppsala is also the venue for Sweden’s most important solar trade fair, the Solelmässan. Of course IBC SOLAR AB was one of the exhibitors on November 27. (more…)
