1. 1. Study case: The water-cooling effect on floating photovoltaic plants performance

   Master-uppsats, KTH/Energiteknik

   Författare :Alice Dragon; [2024]
   Nyckelord :Solar photovoltaic; Floating photovoltaic; Performance analysis; Thermal loss; Panel Efficiency; Cooling effect; Solceller; Flytande solceller; Prestandaanalys; Termisk förlust; Panelens effektivitet; Kylande effekt;

   Sammanfattning : Floating solar technology is relatively new, and it comes with its own set of challenges and opportunities. This master thesis focuses on understanding how Floating Photovoltaic (FPV) projects perform compared to Ground-Based Photovoltaic (GPV) projects, in specific weather conditions. LÄS MER

3. 2. High-Temperature Thermal Energy Storage for Innovative Hybrid CSP/PV Plants : A Comprehensive Design Optimization

   Master-uppsats, KTH/Energiteknik

   Författare :Lorenzo Centonze; [2023]
   Nyckelord :;

   Sammanfattning : By means of a literature review, critical parameters in the context of thermal energy storage systems, particularly packed bed thermal energy storage systems are identified. The goals of this thesis project are to come up with an optimized design for a PBSTES and to evaluate the thermal performance of alternative storage materials derived from byproducts of industrial processes and natural rocks in order to reduce the environmental impact of the designed system.
