What is the net PV energy production in Switzerland and how can we maximize it?

Gloria Serra Coch, Pablo Francisco Martinez Alcaraz

Maximizing solar energy production in Switzerland is key to meet energy transition goals. Understanding in detail the current situation, and the potential for expansion is important to develop effective strategies. With this study, we want to contribute to ...

Performance and degradation in silicon PV systems under outdoor conditions in relation to reliability aspects of silicon PV modules - Summary of results of COST Action PEARL PV

Andrew Wayne Fairbrother, David Moser

This paper presents the main results of COST Action PEARL PV, aiming at finding connections between the observed performance of monitored PV systems and degradation causes and failure modes according to literature with a focus on the most dominant technolo ...

Balancing DSO interests and PV system economics with alternative tariffs

Christophe Ballif, Alejandro Pena Bello, Robin Junod

Distributed rooftop photovoltaics (PV) is one of the pillars of the energy transition yet their widespread integration strains grids, leading to over-voltage, reverse power flow, and infrastructure strain. Furthermore, increased PV self-consumption reduces ...

Optimal sizing and siting of energy storage systems considering curtailable photovoltaic generation in power distribution networks

Fabrizio Sossan, Rahul Kumar Gupta

This work proposes a method for optimal planning (sizing and siting) energy storage systems (ESSs) in power distribution grids while considering the option of curtailing photo-voltaic (PV) generation. More specifically, for a given PV generation capacity t ...

Towards continuous measurements of snow drift and sublimation in polar environments

Michael Lehning, Wolf Hendrik Huwald, John Martin Kolinski, Yael Frischholz, Armin Sigmund, Balthazar Allegri

In polar regions, and specifically in continental Antarctica, the local surface mass and energy balances can be largely controlled by snow transport in form of drifting and blowing snow particles, and sublimation both from the snow or ice surface and from ...
