What happened

A solar energy system caught fire on the roof of an industrial building on the BR-101 highway in Araquari, Santa Catarina, on 16 January 2024. The fire affected approximately 30 square metres of roof. The fire service used 15 litres of water, a truck and three hose lines to extinguish the flames from a distance. After initial containment the service waited for a platform to reach the photovoltaic panels and prevent reignition. The cause remains under investigation by local authorities.
