The urgent global need for sustainable energy has placed solar energy at the forefront of technological innovation. Among the different renewable solutions, solar thermal systems represent a highly efficient and environmentally friendly approach to producing heat for domestic, industrial, and energy applications. However, the optimization of their design and operation remains a scientific and engineering challenge. This book introduces and develops the concept of thermal convexity, a novel theoretical framework that provides deeper understanding into heat transfer processes in solar water heating systems. By combining fundamental principles of conduction, convection, and radiation with advanced modeling techniques, thermal convexity offers a new perspective for analyzing system efficiency and guiding design improvements. This book is structured to progress from the global energy context to the fundamentals of solar thermal technologies, before applying thermal convexity to the simulation and experimental validation of solar water heating systems. The inclusion of both theoretical developments and experimental results ensures a balance between scientific approach and practical relevance. This book is intended for researchers, engineers, and graduate students working in the fields of renewable energy, thermal sciences, and process engineering. It aims to contribute not only to academic knowledge but also to the practical advancement of sustainable technologies, where innovation is urgently needed. We hope readers will find in these pages both the scientific foundations and the inspiration to pursue new directions in solar thermal research and applications.
