Risk Assessment of the Lightning Protection System for Hybrid Solar Power Generation Rooftop System on the Factory Using the FMECA Technique

This paper presents a risk assessment of the lightning protection system for hybrid solar power generation rooftop system on the factory using the FMECA technique. The case study focuses on lightning strikes affecting solar power systems on hybrid roofs, leading to damage. The installation of lightning protection systems to safeguard against natural phenomena, such as direct and indirect lightning strikes, requires an assessment for preventive maintenance. This assessment considers four criteria: efficiency, environment, safety/reliability, and finance. Data collection was carried out using Microsoft Excel, and the lightning protection system was critically analyzed using the FMECA technique. The results indicate that the highest risk in financial operations is within the green, yellow, and red zones, as repair costs are still manageable. The FMECA method proves to be an effective tool for assessing lightning protection systems, enhancing maintenance efficiency, and reinforcing the reliability and stability of the protection system within a suitable budget.
