What happened
A fire broke out on 9 June at a single-family home fitted with photovoltaic roof tiles and a green roof system in Kleve, Germany. Initial reports described a balcony fire; crews found the roof structure involved. About 65 firefighters worked for nearly five hours. The fire stayed confined to the roof and the interior was not affected. Occupants evacuated safely and no injuries were reported. Firefighters partly dismantled the roof to reach hidden hotspots. The cause remains under investigation. The fire service said integrated photovoltaic modules stay energised in sunlight, which complicates operations.
Contributing factors
The fire service said integrated photovoltaic tiles and a green roof made hotspots harder to detect and prolonged the operation. Solar tiles built into the roof are harder to access than panels mounted above a roof, and they can keep generating voltage in daylight.
Lessons learned
- Integrated photovoltaic tiles remain energised in daylight, so crews must isolate circuits before roof entry.
- Green roofs with built-in tiles hide hotspots, so partial roof dismantling must be planned in advance.
- Building-integrated solar is harder to access than surface panels, requiring adjusted ventilation tactics.
Not yet known
- Exact cause of the fire
- Model and age of the solar tiles
- Duration of roof repairs
- Cost of the damage
