Solar hot water panel

The construction of a solar hot water panel helps to understand how it is possible to heat water with the Sun. The basic principle is to circulate water in a black pipe placed behind a glass exposed to the Sun. Thanks to the greenhouse effect and the black colour that absorbs most of the Sun's rays, it is ... »
