Reliability of Photovoltaic Power Systems
Edited by Saeed Peyghami, Peter Behrensdorff, Lars Oberbeck, Seyed Amir Hosseini
Solar photovoltaic (PV) technology has moved from a peripheral generation option to a structural element of the modern electricity system. This shift in scale changes the central analytical question. When PV occupies only a marginal share of electricity supply, the dominant concern is deployment. Once PV becomes deeply embedded in the power system, however, the more consequential question is whether the installed fleet can deliver energy dependably over long operating lifetimes and under diverse field conditions.
In this context, reliability is not a secondary technical attribute, but a governing determinant of energy yield, economic value, and confidence in long-term performance projections. This book approaches PV system reliability as a multiscale and interdisciplinary question, examining the reliability of PV power systems from device to system level, and including context on availability and maintainability. An international team of expert editors and contributors seek to answer the following questions: how reliable are PV systems in practice, how should that reliability be modelled, and which design, testing, monitoring, and operational strategies can most effectively enhance it?
Chapters cover reliability concepts and definitions, fault tree modelling, reliability modelling and design, effects of power converters on reliability, sun tracker systems, failures modes and mechanisms, maintenance of PV systems, and techno-economic analysis.
Reliability of Photovoltaic Power Systems offers systematic and practical coverage of PV system reliability for researchers in academia and industry, experts at grid operators, power plant designers and planners, PV inverter manufacturers and power system operators focuses on the reliability of PV power systems.
About the Editors
Saeed Peyghami is associate professor at the faculty of engineering and science at Aalborg University, Denmark. With a PhD from Sharif University of Technology in Tehran, he started 2017 as postdoctoral researcher at Aalborg. His research interests include reliability and risk assessment in modern power systems, control and stability of power electronics based power systems, and quantum computing applications in power systems.
Peter Behrensdorff Poulsen is group leader at the department of electrical and photonics engineering at Danmarks Tekniske Universitet (DTU), Denmark. Prior positions include CEO of DTU spin-outs and consultant at Danish Technological Institute. His award-winning research focuses on reliability, characterization, and performance of PV cells, modules, and systems, AI for PV production prediction, diagnostic methods, PV module design, and building-integrated photovoltaics, with the goal of increasing lifetime, reducing cost, and enabling new PV applications.
Lars Oberbeck is an expert for solar technologies at TotalEnergies, France, with more than 30 years of experience both in academia and industry. After working for the semiconductor company Infineon and the PV manufacturer SolarWorld, Lars joined TotalEnergies to head the solar R&D department. As a programme manager at the Institut Photovoltaique D'Île-De-France (IPVF), he also leads a team that focuses on techno-economic and environmental assessment of PV technologies.
Seyed Amir Hosseini is a postdoctoral research fellow at the Department of AAU Energy, Aalborg University, Denmark, where he develops analytical methods for the reliability, stability, and control of modern power systems. His research interests include power system reliability and risk assessment, renewable energy integration, frequency control, smart grids, quantum computing applications in power systems, demand-side flexibility, and battery energy storage systems. He received the BSc, MSc, and PhD degrees in Electrical Engineering from Sharif University of Technology, Tehran, Iran.
