Optimized market value of alpine solar photovoltaic installations

Jérôme François Sylvain Dujardin, Annelen Kahl

Solar photovoltaic (PV) is the most rapidly expanding renewable resource worldwide. Yet, its full potential may be hindered by mismatches with market demand and correlated production profiles. In this research, we explore a case study of innovative PV plac ...

SWEET-EDGE: Enabling Decentralized renewable Generation in the Alps

Michael Lehning, Jérôme François Sylvain Dujardin, Annelen Kahl

The overall EDGE objective is to fast-track the growth of locally-sourced decentralized renewable energy in Switzerland and to ensure that by 2035 and 2050, when ambitious shares of renewable energy are reached, the Swiss energy system is designed and oper ...

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 ...

Synergistic optimization of renewable energy installations through evolution strategy

Michael Lehning, Jérôme François Sylvain Dujardin, Annelen Kahl

With large parts of the world moving toward renewable energies, there is an urgent need to organize this large-scale transition effectively. This paper presents a new methodology to guide the planning and siting of renewable electricity generation for coun ...

Floating PV in mountain artificial lakes: a checklist for site assessment

Annelen Kahl

Floating photovoltaics is a emerging approach to deploy photovoltaics on water bodies. Thanks to its high overall global potential and the extensive experience gained (with more than 2 GWp installed and than 510 plants, up to 2020), it represents a promisi ...

The bright side of PV production in snow-covered mountains

Michael Lehning, Jérôme François Sylvain Dujardin, Annelen Kahl

Our work explores the prospect of bringing the temporal production profile of solar photovoltaics (PV) into better correlation with typical electricity consumption patterns in the midlatitudes. To do so, we quantify the potential of three choices for PV in ...

Charting the course: A possible route to a fully renewable Swiss power system

Michael Lehning, Pedro Filipe De Almeida Manso, Jérôme François Sylvain Dujardin, Albertus Christiaan Kruyt, Annelen Kahl, Stuart John Bartlett

The prospect of a renewable transition seems plausible for many countries, but can be shrouded in risks, costs and challenges. This paper illuminates a path for such a transition with a numerical investigation, aimed at resolving the power dynamics of a co ...
