6 FAQs about [Common hidden dangers of photovoltaic module brackets]

What are the risks of a PV module?

Cell cracking is also a common defect which can take place at any stage in lifetime of PV module. Hotspots may cause irreversible damage to the cells and lead to huge power losses. Hail storms cause severe mechanical damage to the modules and may results in glass breakage and/or hidden cracks. 9.2. Fire risks and their mitigation 1.

Are PV modules a fire risk?

Besides underperformance and unreliability issues, there are fire risks associated with PV modules installed in the field, building applied PV (roof-mounted modules) and building integrated PV modules (PV roof tiles, PV facades, etc.), as bottom of modules contain combustible materials i.e. encapsulant and back sheet.

Are PV panels a hazard?

This hazard grows if the support beams are weakened during a fire. The modules could also fall during the fire, endangering both inhabitants and first responders. Be careful during the designing process and consult with the structural engineer if necessary. Always inform firefighters of the presence of a PV system on the roof. 4.

What is a photovoltaic mounting system?

Photovoltaic mounting systems (also called solar module racking) are used to fix solar panels on surfaces like roofs, building facades, or the ground. [ 1 ] These mounting systems generally enable retrofitting of solar panels on roofs or as part of the structure of the building (called BIPV). [ 2 ]

How dangerous is a PV system?

Electrical shock: PV modules keep producing power as long as they are exposed to a sufficiently powerful light source. Even artificial light sources from halogen lamps can produce enough power to energize PV systems to a dangerous level. The same threat can come from light emanating from a nearby fire.

Why do PV modules deteriorate after installation?

It happens only few years after system installation and gradually degrades the performance of PV module. This degradation shows exponential growth. This occurs due to presence of stray currents in ungrounded PV systems . The modules with negative voltage or positive voltage to ground are exposed to this degradation.
