Solar World Record on the Tissot Arena in Biel, Switzerland


The world’s largest in-stadium solar power plant in Biel, Switzerland, uses 62 ABB TRIO inverters and has a capacity of 2.1 MW.

The Tissot-Arena is a multifunctional sports arena for soccer and hockey. The facility also contains a curling arena and a covered public space that has restaurants, stores and a multiplex cinema.

The sports complex features an extended roof which has approximately 16,500 square meters of space available for the solar modules – a total size of two soccer fields.

The roof also houses 62 ABB TRIO 27.6 kW inverters with proven reliability, high efficiency up to 98.2 per cent and a broad input voltage range.

TRIO inverters were chosen because of their two independent MPPTs (Maximum Power Point Tracker) per inverter which guarantee optimal energy output in the case of multiple strings with different orientations and angles.

The installation is the largest solar power plant integrated into a sport stadium in the world. The average annual production is expected to be roughly two gigawatt hours:
installed capacity is 2,106 kilowatt peak (kWp).

The expected annual energy production will equal the consumption of approximately 500 average Swiss households.
