A novel lightning mast layout to eliminate shading effect on PV panels

Year: 2024

Type: article

Abstract: Globally, solar energy technologies are increasingly being implemented to combat climate change. The appeal of photovoltaic (PV) systems lies in their ability to efficiently convert sunlight into electricity, making them popular among homeowners, manufacturers, and businesses. To maximize the output of a PV system, it is crucial to install the panels in a location with ample sunlight exposure and minimal shading. Typically, PV panels are mounted on rooftops to avoid shading and reduce the risk of lightning strikes during storms. When a lightning strike occurs, the energy can potentially damage the building's electrical system, posing a serious threat. To mitigate this risk, engineers implement direct lightning protection measures. This paper focuses solely on direct lightning protection methods, discussing the importance of the earth grid and the factors influencing its effectiveness. Additionally, the paper introduces a new layout for lightning masts for PV systems with back-to-back east and west panel orientations where space constraints limit the separation of PV rows. This approach is considered novel as it cannot be found in any published peer-reviewed works. A detailed case study is also presented.
