Increasing the PV hosting Capacity of Distribution Grids with Distributed Storage: Siting, Sizing and Costs

Mario Paolone, Fabrizio Sossan, Rahul Kumar Gupta, Enrica Scolari

The capacity of electrical distribution systems of hosting photo-voltaic (PV) generation is limited due to the requirements of distribution system operators (DSOs) to respect statutory voltage levels along feeders and not exceed line current limits. Tradit ...

A city-scale roof shape classification using machine learning for solar energy applications

Jean-Louis Scartezzini, Dan Assouline, Nahid Mohajeri Pour Rayeni, Bérénice Guiboud, Andreas Bill

Solar energy deployment through PV installations in urban areas depends strongly on the shape, size, and orientation of available roofs. Here we use a machine learning approach, Support Vector Machine (SVM) classification, to classify 10,085 building roofs ...

Field Performance versus Standard Test Condition Efficiency of Tandem Solar Cells and the Singular Case of Perovskites/Silicon Devices

Christophe Ballif, Stefaan De Wolf, Björn Niesen, Olivier Denis Dupré

Multijunction cells may offer a cost-effective route to boost the efficiency of industrial photovoltaics. For any technology to be deployed in the field, its performance under actual operating conditions is extremely important. In this perspective, we eval ...

Multi-period multi-time optimisation of CO2 based district energy systems

François Maréchal, Luc Girardin, Paul Michael Stadler, Raluca-Ancuta Suciu

Energy system design should take into account the hourly, daily and seasonal variations of both the energy demand and the considered utilities, and therefore requires a multi-time-resolution problem formulation. Multi-period / multi-time optimization is ne ...

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, Eleonora Annigoni

We present an electrical model developed with LT SPICE that simulates the performance of a string of cells with disconnections in the electrical circuit. In a previous contribution, we quantified experimentally how the module performance is affected when o ...

In-situ Determination of Moisture Diffusion Properties of PV Module Encapsulants Using Digital Humidity Sensors

Christophe Ballif, Eleonora Annigoni, Marko Jankovec

We conducted a long-term (>6500 h) in-situ PV module humidity monitoring experiment, where digital humidity sensors encapsulated in different encapsulants (EVA, TPO, POE and ionomer) were exposed to different humidity conditions in a climatic chamber. From ...
