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 ...

Design Rules to Fully Benefit From Bifaciality in Two-Terminal Perovskite/Silicon Tandem Solar Cells

Christophe Ballif, Quentin Thomas Jeangros, Mathieu Gérard Boccard, Olivier Denis Dupré, Pierre-Jean Alet, Arttu Matias Tuomiranta

The photovoltaics industry is adopting bifacial systems which offer improved energy harvesting compared to monofacial ones. This stems from the collection of light reflected by the surroundings on the rear side of the modules, leading to system-level gains ...

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 ...

Deep learning in the built environment: automatic detection of rooftop solar panels using Convolutional Neural Networks

Roberto Castello, Jean-Louis Scartezzini, Adrian Guerra, Martin Esguerra

Mapping the location and size of solar installations in urban areas can be a valuable input for policymakers and for investing in distributed energy infrastructures. Machine Learning techniques, combined with satellite and aerial imagery, allow to overcome ...

Influence of photovoltaic panel orientation on modern energy systems in residential buildings

Luise Middelhauve

The aim of modern energy systems is to be independent of fossil fuels and to minimize their impact on the environment. Photovoltaic (PV) panels are a common solution for renewable electric energy generation, but the volatility caused by the fluctuation of ...

Glass-free lightweight PV building elements: solutions to minimize weight and maximize durability

Ana Cristina Oliveira Martins

In densely populated countries, little free land is available for the deployment of photovoltaics (PV) in field installations. In addition, 40% of the world's demand for electricity is related to buildings. These facts provide a strong argument for the acc ...

Urban planning support based on the photovoltaic potential of buildings: a multi-scenario ranking system

Giuseppe Peronato

An increased use of renewable energy and of energy efficiency measures in buildings is needed to face the urgency of climate change. Buildings are in fact among the highest worldwide consumers of primary energy, mostly of fossil fuel origin, while still ma ...

Quantifying and modeling the impact of interconnection failures on the electrical performance of crystalline silicon photovoltaic modules

Christophe Ballif, Antonin Faes, Jacques Levrat, Alessandro Francesco Aldo Virtuani, Matthieu Despeisse, Fanny Sculati-Meillaud, Eleonora Annigoni

Failures in the metallic interconnections are among the main degradation modes for photovoltaic modules. Fatigue accumulation due to thermomechanical stresses can result in deterioration of the solder joints or in broken ribbons. In this paper, we first qu ...

Field test and electrode optimization of electrodynamic cleaning systems for solar panels

Christophe Ballif, Aïcha Hessler-Wyser, Antonin Faes, Jacques Levrat, Nicolas Badel, Nicolas Würsch, Matthieu Despeisse

Soiling is the major cause of power loss of photovoltaics (PV) and concentrated solar power (CSP) in desert areas. Electrodynamic cleaning system (EDS) is an automatic and water-free integrated cleaning system for mirrors or solar panels, which uses pulsed ...
