Swiss logistics firm invests in a 2.34 MWp rooftop solar PV system employing Delta inverters
In Frauenfeld, Switzerland, the logistics firm Rieser + Vetter installed on their distribution center one of the largest Swiss commercial rooftop PV systems in order to offset carbon emissions and benefit from remuneration via a feed-in tariffTeningen, )
Fuchs Wohnbau AG Solartechnik was selected for the system engineering and main turnkey construction of the solar project.
PV arrays were installed on several warehouse rooftops at the Frauenfeld site. 8293 LG solar modules in total were utilized in the solar PV system.
46 Delta RPI M50A inverters (each with a rated power output of 55 kVA) were selected for the PV project and installed on several of the warehouse exteriors. The solar inverters were purchased from Delta sales distribution partner, Baywa r.e.
The RPI-series inverters have a high maximum efficiency of 98.6% to help ensure a good solar energy yield. The rugged aluminum chassis and IP65 protection rating provide a secure moisture seal that is fitting for the periodic rain and snow common in this region of Switzerland.
According to Erich Stutz, the Solar Installation Manager at Fuchs Wohnbau AG, “Delta inverters were chosen due to the compact form factor of the units with a very high power output of 55 kWs. In addition, the good reputation of Delta as a financially viable manufacturer gives us confidence that they will be around in the long term to support their inverters for the entire guarantee period.”
Construction of the project began in April 2016 and commissioning of the system took place in September 2016. The new solar system now generates around 2.1 GWh of electricity per year, and the logistics firm is expected to reduce its carbon footprint by about 1,688 tonnes of carbon dioxide per year.
Delta is proud to be able to supply its inverters to this project and to have a good cooperation with like-minded companies that want to reduce carbon output to support the environment while also gaining financial benefits from the predictable and clean solar PV energy resource. Delta is working together with Fuchs Wohnbau AG to supply its solar inverters for further PV projects within Switzerland.
