by

One thing is for sure, it doesn’t get any greener than installing a photovoltaic system on a green roof. Recent reports have shown that this combination is very effective and has a positive effect on the performance of PV modules, for example, green roofs improve the PV yield. On top of that, the ecological aspect is of course also interesting, as green areas enable new species-rich habitats for flora and fauna due to the partial shading of the roof. There is no doubt that the combination of PV and green roof has its advantages, but there are also some things to consider. (more…)

“Mounting systems” blog series part 4: Full capacity for business buildings – flat roofs

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.

Flat roofs (generally with up to 10 degrees inclination and building heights of up to 25 m) are particularly well-suited to the installation of a PV system – above all when there should be a lot of PV capacity on the roof. (mehr…)
