Roof fire in Klipphausen: Photovoltaic system causes total damage!

Klipphausener Ortsteil Bockwen, Deutschland - On Sunday afternoon, the municipality of Klipphausen was hit by a shocking incident: a family home in the Bockwen district caught fire. According to Sächsische.de , the photovoltaic system on the roof was finally caused by the roof collapsed. Fortunately, the residents were not in the house at the time of the incident, so there were no injuries to complain, but the building is now uninhabitable.

The fire brigades from Klipphausen, Meißen, Coswig and Weinböhla were quickly on site and used several jet pipes to control the fire and ultimately extinguish them. The police have already investigated the cause of the fire to find out how this dangerous incident could occur.

Security risks of photovoltaic systems

The risk of fire in photovoltaic systems is a topic that is increasingly focusing on. A fire can be due to various factors, for example due to installation errors and defects in planning or products. This was also confirmed by the results of an extensive research project by experts from Germany and Switzerland, which have examined the fire risks in solar systems for almost four years. In a free, over 300 -page guide, the findings were published, from which it becomes clear that while over 1.5 million solar systems are in operation in Germany, a clear clarification of safety precautions is urgently required.

As can be seen from the guide, the risk of fires can be further reduced through targeted measures, including the improved qualification of the installers and technical acceptance. Florian Reil of TÜV Rheinland emphasizes that fire risks are low, but should not be ignored. The situation is particularly critical when it comes to the high voltage in photovoltaic systems, where up to 1,500 volts can be available - even if the system is separated from the power grid. This can make the work of the fire brigade considerably more difficult because the high DC voltages can lead to lighting sheets that endanger the emergency services.

recommendations for fire fighting

In order to ensure the security of the fire brigade, it is recommended in accordance with the VDE directive VDE-AR-E 2100-712 that DC lines are switched down to less than 120 volts as soon as the AC page is switched off. In addition, it is advisable to install DC outdoor switches with remote release or special switch-off devices near the modules. However, these are often not optimally placed, which can lead to dangerous tensions on long line paths.

The alert willingness of the fire brigade and the need for well -planned security protocols are urgent in this context. Especially in the case of fire in Klipphausen it becomes clear that despite the increasing use of renewable energies, the safety of human life and buildings must have a top priority.

The topic of safety precautions for photovoltaic systems are also considered urgent by many experts, especially in accordance with the aging of the materials. A look at the guidelines mentioned above shows that the fire risk can be reduced by regular checks and new technologies such as light -bog tectors.

Overall, it remains to be hoped that the high potential of solar technology can be used through increased education and technical optimizations without creating a danger to building security and emergency services.
