This book gives you theory and design of PV/T systems. Are you interested in solar energy? If you are, you must have read about solar panels, or photovoltaics (PV). If you have installed a photovoltaic system, you must have noticed it not to generate the amount of power mentioned in its datasheet. A major issue that PV suffers from is its temperature, which causes a drop in its power. Among the solutions to this issue is to use active cooling methods, such as the hybrid photovoltaic thermal (PV/T) system. These systems can produce electrical and thermal energy simultaneously and within same area. The thermal collector serves to cool down the PV surface temperature, which negatively affects the PV efficiency, to reclaim the efficiency or bring it back close to standard testing conditions value. Moreover, the thermal collector will convey this heat using a working fluid and extract it as thermal energy. On the other hand, the electrical power generated from the PV can be utilized in standalone or grid-connected configuration. Moreover, the book presents a novel PV/T collector which can utilize nanofluids and nano-Phase Change Material (PCM) to enhance its performance in tropical climate conditions. The methods used to develop the heat transfer and energy balance equations are presented as well. PV/T collector numerical simulation using MATLAB and computational fluid dynamic (CFD) was also presented. Finally, the approach of life cycle cost analysis (LCCA) is presented to evaluate PV/T with nanofluid and nano-PCM, economically.
This book focuses on solar energy and its applications in Iraq and its neighboring countries. Iraq suffers from electricity shortages and faces many challenges to meet and overcome current and future increases in electrical demand. Although Iraq relies primarily on petroleum as an energy source, many scientists agree that the future of energy efficiency and safety will rely heavily on the implementation of green and renewable energies. This book is aimed at researchers, policymakers, and students and discusses how PV systems can be successfully implemented in order to reduce dependency on fossil fuel resources. Contains case studies and examples to enhance practical application of the technologies presented; Presents actual adopted Iraqi PV projects; Explains the use and application of photovoltaic cells.
