The collapse of part of Dutch Eredivisie football club AZ Alkmaar’s stadium roof has been blamed on the weight of solar panels installed four years ago.
The club had installed 1,700 solar panels on the stand in 2015, with the work being carried out by Dutch company Amstelveen Sunprojects.
Nobody was hurt when part of the roof in the Molenaar Stand collapsed at the weekend. The club has hired engineering and consultancy firm Royal HaskoningDHV to conduct an investigation into the incident at AFAS Stadion.
Officials from Royal HaskoningDHV and the municipality of Alkmaar inspected the site on Sunday.
Chris de Wild – a spokesperson for the municipality of Alkmaar, said:
According to the building decree, solar panels can be installed without an adapted building permit or inspection. Calculations by the constructor showed that the roof could support the panels.
At the time, we were kept well informed about the plans and calculations, that was sufficient for the municipality.
The AFAS Stadion has a capacity of 17,023 people, opened in 2006 and is located in Alkmaar, 25 miles outside Amsterdam.
