ABSTRACT
Solar thermal technologies are among the most diverse and effective renewable energy technologies. They range from low temperature (<70°C) and simple in operation technologies such as solar space heating and solar cooking to high temperature (>200°C) and sophisticated ones like solar air conditioning and solar thermal power generation. Solar thermal technologies, similarly, have a broad economic bandwidth among them. The most successful application of solar thermal technologies so far has been in the form of solar water heating. In this entry, a brief overview of the prominent solar thermal technologies has been presented in which the technology fundamental and operational principles of these technologies have been precisely discussed.
