Abstract

Solar photovoltaics, especially rooftop systems also called distributed solar photovoltaics, are crucial in the ongoing energy transition. Modeling these systems is vital to understanding their role in a decentralized energy system. While ground‐mounted photovoltaic power plants are easier to model, generalizing yield profiles for rooftop systems is challenging. This study aims to estimate yield loss effects for rooftop solar photovoltaic systems compared to optimized ground‐mounted systems. Anticipated yield losses are 18% for residential, 7% for commercial, and 4% for industrial rooftop systems. The impact on residential prosumers' viability is assessed by comparing prosumer system optimization results with and without yield losses. Results show a non‐uniform change in installed solar photovoltaic and battery capacities, with a tendency to compensate for reduced yields by increasing photovoltaic capacity by up to 20%, given favorable cost prospects by 2050. The annualized total cost of energy for prosumer households could therefore increase by up to 20% by 2050. Despite yield reductions, installing a solar photovoltaic prosumer system remains more favorable than relying entirely on‐grid electricity. This study highlights the importance of considering yield losses in rooftop solar photovoltaics and the significant role of prosumers despite identified yield losses. [ABSTRACT FROM AUTHOR]

Abstract

This work analyses load profiles for East African microgrids, and then investigates the integration of electric two-wheelers and portable storage into a solar PV with battery microgrid in Uganda, East Africa. By introducing e-mobility and portable storage, demand side management strategic load growth can thus be achieved and electricity access can be expanded. Battery degradation is also considered. The results showed a 98.5% reduction in PV energy curtailment and a 57% reduction in the levelized cost of energy (LCOE) from 0.808 USD/kWh to 0.350 USD/kWh when the electric two-wheeler and portable storage loads were introduced. Such reductions are important enablers of financial viability and sustainability of microgrids. It is possible to avoid emissions of up to 73.27 tons of CO2/year with the proposed e-bikes, and an average of 160 customers could be served annually as off-microgrid consumers without requiring an investment in additional distribution infrastructure. Annual revenue could be increased by 135% by incorporating the additional loads. Sensitivity analyses were conducted by varying component costs, the battery lifetime, the interest rate, and the priority weighting of the additional loads. The battery costs were found to be a major contributor to lifecycle costs (LCC) and also have a big impact on the LCOE. The interest rate significantly affects the LCC as well.

Abstract

The market for microinverters is growing, especially in Europe. Driven by rising electricity prices and an easing in legislation since 2024, the number of mini-photovoltaic energy systems (mini-PVs) being installed is increasing substantially. Indoor and outdoor studies of microinverters have been carried out at Paderborn University since 2014. In the indoor lab, conversion efficiencies as a function of load have been measured with high accuracy and ranked according to Euro and CEC weightings; the latest rankings from 2024 are included in this paper. In the outdoor lab, energy yields have been measured using identical and calibrated crystalline silicon PV modules; until 2020, measurements were carried out using 215 Wp modules. Because of increasing PV module power ratings, 360 Wp modules were used from 2020 until 2024. In 2024, the test modules were upgraded to 410 Wp modules, taking into account the increase from 600 W to 800 W of inverter power limits, which is suitable for simplified operation permission ("plug-in") in many European countries within a homogenised legislation area for such mini-photovoltaic energy systems or "balcony power plants". This legislation for simplified operation also covers overpowered mini-plants, although the maximum AC output remains limited to 800 W. Presently, yield assessments are being carried out in the outdoor lab, which will take at least a year to be valid and comparable. Kits consisting of PV modules, inverters, and mounting systems are also being evaluated. Yield rankings sometimes differ from efficiency rankings due to the use of different MPPT algorithms with different MPP approach speeds and accuracies. To accelerate yield assessment, we developed a novel, simple formula to determine energy yield for any module and inverter configuration, including overpowered systems. This is a linear approach, determined by just two coefficients, a and b, which are given for several inverters. To reduce costs, inverters will be integrated into the module frame or the module terminal box in the future. [ABSTRACT FROM AUTHOR]

Abstract

Reformatorische Paulusauslegung wird in der gegenwärtigen Paulusforschung meist mit Martin Luthers Vorlesungen zum Galater- und zum Römerbrief gleichgesetzt. Sie dient als Gegenbild, von dem sich moderne Paulusexegese abgrenzt. Die Aufsätze dieses Bandes zeigen, dass die Auslegung der Paulusbriefe im 16. Jahrhundert vielfältiger und als Gesprächspartner für heute interessanter ist. Ein Schwerpunkt des Bandes liegt auf der Schweizer Reformation in Zürich, der Oberrheinregion und Genf. Daneben kommen Ausleger der Wittenberger Reformation neben Luther sowie täuferische und humanistische Ausleger in den Blick. Eine Besonderheit dieses Bandes ist, dass auch deuteropaulinische Briefe einbezogen werden.

13. Das 'sterbende Weizenkorn'

Abstract

Paul’s statement that seeds die after sowing in the soil before they germinate is often assessed as a commonly held view of antiquity. Some scholars even claim that it conforms to the scientific standards of ancient philosophy. This paper examines the sources cited as evidence for this claim and shows that it is untenable. Paul’s formulation is very unusual. His idea that seeds die does not make sense on the background of ancient botany. Similar, albeit not identical ideas can be found only in the context of some ancient mystery cults. It is difficult to assess how wide-spread they were.

Abstract

This article compares De clementia, a somewhat neglected minor work of the Roman Stoic philosopher L. Annaeus Seneca, and Paul’s Letter to the Romans. First, Seneca’s ideas about rule as a god-given task of moral improvement of the subjects and the role of mercy (clementia) within it are analysed. Then, Seneca’s argument is compared with Paul’s thoughts concerning salvation by grace in his Letter to the Romans. Seneca’s short political treatise De clementia shows a considerable number of interesting and specific agreements with Paul’s reasoning in the Letter to the Romans, even more than his other writings, which have been in the focus of scholarly investigation. Finally, some suggestions are made about the possible source(s) of the convergences and how they could be interpreted.

Abstract

In Tit 2,2-7a wird moralische Unterweisung nach Geschlecht und Alter spezifiziert dar- geboten. Die massgeblichen Kommentare des 20. Jahrhunderts halten die Zuteilung der einzelnen paränetischen Inhalte auf die Gruppen für mehr oder weniger zufällig. Sie wer- den entweder als traditionell oder als antihäretisch bzw. antiasketisch motiviert erklärt. Ausgehend von auslegungsgeschichtlichen Beobachtungen versucht dieser Beitrag, Tit 2,2-7a in antike Diskurse zum Thema Alter einzuordnen, und reflektiert, welche Auswir- kungen eine solche Einordnung für die heutige theologische Relevanz des Textes hat.

Abstract

Die reformierten Kirchen der Schweiz weisen vielfältige Amtsverständnisse auf. Ihre Konturen und Konfliktlinien spiegeln sich auch in der Amtseinsetzung, der Ordination. Vor dem Hintergrund zurückgehender Mitgliederzahlen und Finanzen und der zunehmenden weltanschaulichen Pluralisierung muss darum nicht nur über die Ämter und Dienste der Kirche, sondern auch über die Ordination neu nachgedacht werden. Die Beiträgerinnen und Beiträger behandeln das Thema Ordination retrospektiv und zukunftsorientiert, gegenwartsanalytisch und auch im Blick auf den europäischen Protestantismus. Die Texte aus den Bereichen Neues Testament, Kirchengeschichte, Dogmatik, Ökumenik, Soziologie, Praktische Theologie und Kirchenrecht bieten einen fundierten Überblick und Impulse für die weitere Diskussion. Mit Beiträgen von L’ubomír Batka, Judith Becker, Michael N. Ebertz, Cla Reto Famos, Stefan Krauter, Ralph Kunz, Kerstin Menzel, Sabrina Müller, David Plüss und Matthias D. Wüthrich.
