Acoustic assessment of PV systems on motorways

Acoustic assessment of PV systems on motorways

In the Energy Strategy 2050, solar energy plays a primary role in Switzerland's future energy supply. In addition to locations such as building facades and roofs, the potential of photovoltaic (PV) arrays along transport infrastructure (retaining walls, noise barriers, etc.) has also come into focus. The installation of solar panels there can influence sound propagation and can either reduce noise (as an obstacle) or increase it (as a reflective surface). As part of a pilot project on behalf of the Federal Roads Office (FEDRO), G+P accompanied the acoustic assessment of a planned PV system along a section of motorway, focusing in particular on reflections, which can lead to undesirable increases in noise for local residents.
CPX Season 2024

CPX Season 2024

The G+P pavement acoustics team has been carrying out close-proximity measurements (CPX) throughout Switzerland since 2008. The eventful 2024 CPX measurement season came to an end with the first snowfall at the end of November. While initial preparations for next year are already being planned and organised, we would like to summarise the 2024 CPX measurement season at the end of the year.

One year of communicating values

In January 2024, as "The New Boss", I explained in a video statement what is important to us and to me at G+P. After almost a year as the new CEO, it's time for a little look back. Our values take centre stage. Values are a key success factor, especially for SMEs like us.

Our 40th anniversary

A weekend full of memories in Châteaux-d'Oex. Last weekend, we celebrated a special event: 40 years of company history. Our anniversary trip to Châteaux-d'Oex was a complete success, bringing us together with 60 employees from various branches. Thanks to bright sunshine, a great atmosphere and a varied programme, this weekend will remain unforgettable.

«As part of the pavement acoustics team, I carry out acoustic measurements throughout Switzerland and evaluate the measurement results in the office. In doing so, I particularly appreciate the thematic reference to my geography studies. In addition, unlike many of my fellow students, the combination of my professional activities and my studies was made extremely easy for me by the possibility of flexible working hours, for which I am extremely grateful.»
