How Forward-Scattering Snow and Terrain Change the Alpine Radiation Balance With Application to Solar Panels

Michael Lehning, Annelen Kahl

Rough terrain in mid- and high latitudes is often covered with highly reflective snow, giving rise to a very complex transfer of incident sunlight. In order to simplify the radiative transfer in weather and climate models, snow is generally treated as an i ...

Parametric study of URBAN morphology on building solar energy potential in Singapore context

Jérôme Henri Kämpf

In 2014, the Singapore government announced plans to increase the adoption of solar power, including by integrating solar PV systems into the urban environment. Careful planning of a neighbourhood at early design stage, which determines the overall urban m ...

Reliability and Performance of Model Predictive Control for Demand Response with Residential Heat Pumps

Frédéric Louis-Pierre Raphaël Marie Amblard

Distributed energy resources like solar panels and wind turbines are increasingly replacing fossil fuel energy sources. Due to their natural fluctuations they cause imbalance in the power grid when their production does not overlap with demand. Thus, there ...

Investigations into Nanostructured Materials for Water Splitting and Direct Solar Energy Harvesting

Filip Mateusz Podjaski

This thesis deals with different aspects of renewable energy transformation and storage concepts and connects them. Although renewable energy installations are growing worldwide, their use is limited by storage technologies. As such, water splitting for hy ...
