This book proposes the development of solar water heating applications. The theme is topical since it is linked not only to its economic advantages, but above all to considerations relating to environmental protection. Indeed, the operation of water heating systems, industrial or domestic, by this solar energy, is characterized by the absence of polluting discharges (fumes containing CO2 and Nox), radioactive dangers and bulky waste (nuclear center). Overall, this book deals with the description of solar energy sources (thermal and photovoltaic), the structures of innovative water heating...
