Buildings that have photovoltaic systems on their roofs and facades are becoming more common and this trend is expected to continue to rise. However, despite being a safe technology, it represents a notable increase in the risk of fire derived from this installation, which must be taken into account when carrying out risk analysis and designing fire protection systems, whether they are active or passive.
During the last decade, the installation of photovoltaic systems has spread on a large scale throughout the national and international territory. The adoption of this solution has found wide feedback thanks to its environmental sustainability characteristics, since it allows to produce electricity in an eco-sustainable way, in addition to quickly amortizing the installation based on the Kw / h (kilowatt hours) produced.
This guide only discusses linear fiber optic fire detection, but other linear detection methods (digital cable) or thermal imaging cameras could also be used.
It is recommended to install automatic fire detection in converters, transformers, batteries, power factor correction equipment and distribution panel rooms. As well as in the solar panels themselves. All this can be protected with the same sensor cable.
With the fiber optic LHD solution it is possible to monitor the temperature value along the entire route of the sensor cable and control every slight variation as a function of time (Rate of Rase) even at very low temperatures. It also allows the assignment of a set of different alarm criteria for each zone configured on the sensor cable. The sensor cable withstands temperatures of up to 750ºC for 2 hours (certified) while maintaining its effectiveness and giving an idea of the size of the fire.
