Customer ServicePartial shading and fading in the heat are the most critical failure modes due to external events. The partial shading effect is primarily due to new construction near the panels and grass growing above the height of the solar panels. Proper care can significantly minimize the probability of partial shading and new shading elements.
The occurrence of electrical and fire risks can vary based on the type (e.g., rooftop, ground-mount), setting (e.g., residential, commercial, utility-scale), and weather conditions during PV installations.
It usually occurs due to electro-chemical reaction between the metallic parts/connections and water . The common reason for this is penetration of moisture and oxygen in the PV module due to glass breakage, etc. or during high and prolonged humidity conditions .
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.
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. Most of the time, it happens at negative voltage with reference to ground potential.
The fire spread area is limited by size of PV arrays. This indicates that the configuration of PV installation has also a strong influence on fire propagation. A study studied fire dynamics and flame spread behavior at roofs having PV modules installation. The experimental setup for one of the studied case in this research is shown in Fig. 23.
