Martin Mesmer Director Operations GSSG Solar

Monitoring systems are good for seeing whether there is an issue in the field. They give you an indication of whether there will be a problem in the near future.

The harshest environmental conditions

Dryness and an extreme installation height

Rijn Capital Chile operates a complex consisting of six photovoltaic systems that work reliably even under extreme conditions. The substantial level of dryness and extraordinary installation height at 2,600 metres above sea level turn what would otherwise be standard technological requirements into a real challenge.

Powerful “sunroof”

Connected to the grid in no time at all

Just under a year separated the initial idea and the grid connection of Switzerland’s most powerful rooftop photovoltaic system. Weidmüller’s expertise and experience helped achieve this record-breaking time.

Sustainable football stadium

Environmentally-friendly contribution to Switzerland’s biggest in-roof photovoltaic system

A 1.415-MW photovoltaic system comprising 4,730 accessible solar modules needed to be installed on the roof of a local football stadium. Following an initial visit to the general contractor, an agreement was quickly reached with the project managers. Weidmüller impressed with its solutions and professional support.

Photovoltaics make water treatment “greener”

As clear as daylight!

Covering an area of five football fields, the 3-MW system on the roof of the Aquiris water treatment plant is the largest of its kind in Belgium. Combiner boxes from Weidmüller help ensure that the 10,000 installed photovoltaic modules achieve a peak performance of more than 3.2 MW.

An outstanding team feat

Weidmüller supports record-breaking project from Electricité de France (EDF)

An area of 400 hectares, 1.5 million photovoltaic modules, a power output of 143 MWp, an investment of EUR 434 million and a set-up time of 11 months: that was the core data of the huge photovoltaic system built by EDF near Nancy in France.
