123989 - Energy Fluctuation of Floating Photovoltaic Solar Panel Due to Wave-Induced Motions 

Solar photovoltaics is predicted to be the most widely used energy method in the future. However, the expansion of solar panels is currently limited by scarce land and lake spaces. To meet the world's future clean energy target, floating solar panels are expected to be deployed on abundant ocean space, but floating photovoltaics in the ocean will be subject to loads and motions induced by ocean waves. In particular, a continuous pitch motion causes the solar panel surface to constantly change its sunlight intake angle, which could lead to a loss of energy. 

To investigate this phenomenon, a novel interdisciplinary experimental facility is established at Cranfield University, where a solar simulator is installed on top of a wave tank. A floating solar unit is placed in the middle of the tank, subject to wave-induced motions. The motions are measured and related to the energy output fluctuation measured at the same time. In this way, empirical relations are established to predict floating solar power with different motions in different wave conditions. Overall, the work presents a novel experimental approach with valuable benchmark data. With the wave impact considered, the empirical relations provide insights into the ongoing industrial projects and enable accurate power prediction of ocean-based floating solar projects.
