RAU Photovoltaik: plantable noise protection that also generates solar power

RAU Photovoltaik combines effective noise protection with solar power generation, bringing function and economy together in a single system. The structure is based on RAU Klimawand R3, our planted noise barrier, and can be adapted to different sites. The photovoltaic modules are mounted on the Klimawand's steel baskets and oriented to suit local conditions. Depending on the project, up to three rows of solar panels can be integrated, and the wall can still be planted.

According to the data sheet, RAU Photovoltaik can be designed to suit each project and built up to 12 metres high. The base width varies with height and, according to the cross-section, ranges from approx. 0.8 to 3.0 metres. Further advantages include shallow foundations, long service life and greater local acceptance thanks to the combination of planting and power generation. Like any Klimawand, the wall is filled mostly with processed recycled crushed stone certified by the supplier; where excavated soil from the site is suitable, we use it.

Two ways to fix the modules

There are two ways of mounting the modules. In the first, the basket itself is manufactured at the optimum tilt angle for the modules. This is more elaborate and more expensive, but sets the modules at the best angle to the sun. The installation in Leutershausen is built this way.

In the second, angles with holes are welded to the basket and galvanised together with it. They carry an aluminium substructure that holds the modules vertically. We used this method in Seyring, Austria.
