The general behavior of underground temperature distribution is shown in Fig. 1.18. At a great depth, for example, at 20 to 30 meters underground, the temperature is the annual average temperature of the surface, for ex-ample, ̄T = 10 C. At the surface, the temperature varies over the seasons.
Hereby, we present the first version of our book Solar Energy: Fundamentals, Technology and Systems and hope that it will be a useful source that helps our readers to study the different topics of solar energy. It covers the topics that are treated in the three lec-tures on photovoltaics (PV) that are taught at the Delft
