Design and integration of an off-shore off-grid system and an on-land system for comparison on photovoltaic performance

The purpose of this thesis research was to perform a photovoltaic (PV) performance assessment and comparison between a small-scale land-based PV system and an off-shore off-grid floating PV system. Also from this research design guidelines for off-grid off-shore floating PV systems were developed. The research experiment was carried out in The...

The projection of climate change impact on the fatigue damage of offshore floating photovoltaic structures

In marine environment, floating photovoltaic (FPV) plants are subjected to wind, wave and current loadings. Waves are the primary source of fatigue damage for FPVs. The climate change may accumulatively affect the wave conditions, which may result in the overestimation or underestimation of fatigue damage. This paper aims to present a...

Offshore floating PV yield considering wave effect: DC output model and experimental analysis of a commercialized string inverter

The growing global energy demand and correlated rise in carbon emissions are increasing the need of renewable energy sources. This spread requires land to be occupied, competing with other activities such as agriculture and residency. This project can help the spread of photovoltaic (PV) technologies in an environment still little explored: the...

Nonlinear Fluid-Structure Interaction in Large-Scale Offshore Floating Photovoltaics

Efficient and affordable solar energy is essential for reducing greenhouse gas emissions and achieving climate neutrality. Large-scale offshore floating photovoltaics (LOFPV) provide creative opportunities for clean and cost-effective renewable energy production close to populated areas. They are composed of solar modules, a membrane platform,...

Modelling of a Flexible Inflatable Floater: Analysis of the stiffness behaviour of a drop-stitch panel for offshore floating photovoltaics

For floating photovoltaic systems, an uncommon type of offshore structure is considered, which is very flexible and deforms with the motion of the waves. In this research, the bending characteristics of a drop-stitch floater is analysed, which is an inflatable panel. By inflating the drop-stitch floater to a low air pressure, it obtains a...

Fully nonlinear hydroelastic modeling and analytic solution of large-scale floating photovoltaics in waves

This paper concerns the fully nonlinear fluid–structure interaction (FSI) of Large-scale floating photovoltaics (LFPV) in waves. The Euler Bernoulli–von Kármán beam models the structure while potential flow represents the fluid. A set of coupled dynamical equations is established. The fully analytic solution is sought with the unified Stokes...

Theoretical analysis of nonlinear fluid–structure interaction between large-scale polymer offshore floating photovoltaics and waves

The present research analyzes the nonlinear fluid–structure interaction (FSI) of free surface waves with large-scale polymer offshore floating photovoltaics (LPOFPV). The floating structure is modeled as a nonlinear Euler Bernoulli–von Kármán (EBVK) beam coupling with water beneath. The EBVK theory takes the in-plane force into consideration to...

Offshore Solar to Hydrogen System, Located North of Crete, Greece: A techno-economic assessment

The energy transition, is one of the most important topics nowadays. Renewable energy sources contribution in the energy mix is growing rapidly. However, due to their intermittent power output, they cannot ensure system security and stability, and therefore, energy storage technologies are needed. In this direction, hydrogen is an energy carrier...
