Dutch government telecom agency AT is taking an international manufacturer to court for producing faulty solar panels which can cause ‘serious disruption’ to the C2000 communications network used by police and emergency services. The AT has not published the name of the manufacturer  because of legal reasons but confirmed the case involves a ‘big international player’, NU.nl said. The agency has received dozens of complaints from ambulance, police and fire brigade staff in the last year, it writes in its annual report. It is currently investigating if all are down to faulty panels and installation. The solar panel signals affect not only C2000 system but also internet speed, radio and tv reception and phone connections. The AT will be revealing the name of the solar panel manufacturer in the coming weeks.
