Sound Intensity Mapping of Power Generators in Solar Energy Systems: A Case Study on Inverter Noise Emissions

Abstract

This study examines the acoustic emissions produced by power generators in solar energy systems, with a particular focus on inverters. Noise emissions from these systems are frequently overlooked, despite their potential environmental and health effects. Sound intensity mapping (SIM) was conducted at two distances (0.3 m and 1.0 m) and at three different times of the day to identify noise hotspots and characterize variations in sound power levels (SWL). The inverter, a crucial component of solar systems, was found to generate substantial noise, with SWLs reaching as high as 89 dB during peak operation. The findings underscore the significance of acoustic analysis in the design of solar systems and propose mitigation strategies to reduce noise exposure in sensitive environments. This research advocates for the incorporation of acoustic considerations into the planning and implementation of sustainable energy systems.
