Abstract

The floating photovoltaic system has a large potential for development as a new type of power generation technology. Offshore floating photovoltaics face challenges with wave-induced damage to connectors in the array. Numerical models are created to analyze various connection configurations within multi-floating photovoltaic arrays. This study examines the effects of different connector configurations on the pitch response, connector bending angles, connector stresses, and receiving solar irradiance of multi-floating photovoltaic arrays in offshore conditions with regular wave incidence. The study evaluates the dependence of the seakeeping performance of offshore multi-floating photovoltaic arrays on connectors. The results indicate that the multi-floating array connected by the connector with spring damping （CSD） has a better motion response than the hinge connection, and it has a stronger load-bearing capacity than the bolt connection. The CSD connector is ideal for offshore multi-floating photovoltaic arrays due to its superior seakeeping performance and strong ability to receive solar irradiance compared to other connectors. The study is of great importance in expediting the commercialization process of offshore floating photovoltaics.
