Abstract

PV systems have become commonplace due to the costs and availability of PV components. Due to its relatively modern status, lightning protection standards for PV systems are underdeveloped. One aspect to consider is the risk assessment of a structure fitted with a rooftop PV system. However, there is currently no framework available for incorporating a rooftop PV system in the risk assessment of a structure. This paper uses a computational methodology to integrate a small-scale rooftop PV system into the risk assessment of a residential structure. Two approaches are adopted to comparatively analyse the effects of a PV system on the risk of lightning damage to a structure and persons in the structure. It is found that the different approaches of incorporating the PV system into the risk assessment have an effect on the overall risk. Furthermore, results indicate that this effect must be carefully considered together with appropriate conditions when analysing the risk of lightning damage to a structure fitted with a small-scale rooftop PV system.
