Solar energy

Solar energy refers to both electricity and thermal energy that is harnessed from the sun. Solar thermal energy can be harnessed either passively — where no moving parts are required such as for passive solar building design — or actively for a wide range ofapplications, including domestic hot water and space heating via solar thermal collectors. Direct current (DC) electricity can be generated directly from sunlight using photovoltaic (PV) or solar cells that contain no moving parts. In addition, photoelectrochem-ical cells can also be used to generate solar hydrogen, and while this offers interesting potential for energy storage, it is neither a mature nor widespread technology and will therefore not be mentioned further in this chapter.
