Preface Photovoltaic engineering is a multidisciplinary speciality deeply rooted in physics for solar cell theory and technology, and heavily relying on electrical and electpolrlli;c engineering for system design and analysis. The conception, design and analysis of photovoltaic systems are important tasks o h requiring the help of computers to perform fast and accurate computations or simuhfim. Today’s engineers and professionals working in the field and also students of dSa& technical disciplines know how to use computers and are familiar with r~nning .rpeckaliz& software. Computer-aided technical work is of great help in photovoltaics became a# the system components are described by nonlinear equations, and the node circuit quaions that have to be solved to find the values of the currents and voltages, most often do II& have analytical solutions. Moreover, the characteristics of solar cells and PV generators sarongly depend on the intensity of the solar radiation and on the ambient temperature. As k are variable magnitudes with time, the system design stage will be more accurate if a4.1 estimation of the performance of the system in a long-term scenario with realistic tikm series of radiation and temperature is carried out. The main goal of this book is to help understand PV systems operation gathering concepts, design criteria and conclusions, which are either defined or illustrated us& computer software, namely PSpice. The material contained in the book has been taught for more than 10 years as an undergraduate semester course in the UPC (Universidad Politecnica de catahria) in Barcelona, Spain and the contents refined by numerous interactions with the studats. PSpice was introduced as a tool in the course back in 1992 to model a basic solar celI and since then more elaborated models, not only for solar cells but also for PV gemerators, battery, converters, inverters, have been developed with the help of MSc and PhD -dents. The impression we have as instructors is that the students rapidly jump into the tool and am ready to use and apply the models and procedures described in the book by themselves- Interaction with the students is helped by the universal availability of Pspice or mze advanced versions, which allow the assignments to be tailored to the development: of the course and at the same time providing continuous feedback from the students on the
