Comparative performance evaluation of ground-mounted and floating solar PV systems

Abstract

The global shift towards sustainable energy sources, driven by the need to reduce carbon emissions and ensure energy sustainability, has shifted from traditional fuel-based energy generation to a surge in interest in Renewable Energy Technologies such as Solar Photovoltaic. Solar Photovoltaic energy has the potential to mitigate carbon emissions and achieve energy security that is in line with Sustainable Development Goals but challenges such as land requirements and system efficiency persist. This study compares the performance of ground-mounted and floating solar Photovoltaic systems at the Bui Generating Station in Ghana. The findings reveal that floating PV systems have several superiorities over ground-mounted systems, including lower temperatures, higher energy generation capabilities, and more efficient area cover use. However, floating PV systems are also prone to aluminium frame corrosion of the Photovoltaic modules and other metallic components within the mounting structures, which could be mitigated through design modifications. The superior performance of floating Photovoltaic systems suggests their viability as a strategic tool in achieving renewable energy targets. As floating Photovoltaic technology advances, it promises to create a greener and more resilient energy landscape.
