| Outline of Final Research Achievements |
Solar energy is recognized as a promising energy source, and photovoltaic (PV) systems are commonly used to collect it. Many kinds of systems have been designed and proposed, depending on the purpose (such as roof-mounted systems for domestic use or ground-mounted systems for mega-scale photovoltaic systems). However, some PV systems have recently been damaged by strong wind. Wind tunnel tests are commonly used to verify the wind-resistant performance of these systems and thus find ways to prevent this kind of damage. In this paper, we clarify the mitigation effects of wind load acting on a PV system using aerodynamic appendages such as hanging walls and eaves. The mean forces and moments acting on a PV system model are measured in a wind tunnel using a six-component High Frequency Force Balance.
