Solar radiation reaching the Earth surface is the most abundant renewable energy. Solar energy can be harnessed in two types of technologies: Solar Photovoltaics (PV) and Solar Thermal. This chapter deals with the applications of solar thermal technologies in the built environment. The applications presented are electricity generation, hot water production, product drying, cooking, clean water production, space heating, space cooling and refrigeration. Fundamental principles and recent developments and trends of these applications are presented and discussed.
