Modelling Symphony motion: Towards a better understanding of 2D Symphony motion

This work simulates the impact of horizontal motion on the Symphony wave power device. To that end the existing time domain simulation is expanded with a module that simulates horizontal motion in the 2d plane. This extension is coupled with the existing operational modelling. the extension is based on a mathematical motion model based on rigid...

Next Generation Shade-Tolerant Reconfigurable PV Modules for Urban Landscapes

In urban environments, more and more building added and building integrated photovoltaic (PV) systems are found. These systems use conventional PV modules which have a poor performance under non-uniform illumination conditions. When the module is partially shaded, either at least one subgroup is bypassed or the module current is limited by the...

Performance assessment and optimization of a HVAC system integrating a BIPV/T system: Model development and application to the Deep Performance Dwelling of TeamMTL for the Solar Decathlon China 2018

European policy makers have established a set of 20-20-20 targets for the year 2020 in the energy sector, goals based on security of supply, competitive markets and sustainability.
