Bilbao Kirolak, the municipal corporation under the city council of Bilbao, Spain, announced that part of the facilities at the San Inacio Sports Center were closed due to a roof collapse. Other facilities in the city of Bilbao remain open and operational and the cause of the collapse is currently under investigation.

In an interview with local radio, Mayor Juan Mari Aburto said heavy rain and the large number of solar panels on the roof of the sports center were likely the cause of the collapse.

These solar panels were installed after the project was awarded to Inbisa Construcción in 2010 and became the largest photovoltaic roof in Bizcaia at the time. The project originally consisted of 120 solar panels, but based on photos of the collapse, there are an estimated 168 at the site. The company's total investment in the project amounted to EUR 411,000 (USD 440,797).
