Methods Used To Collect Solar Thermal Energy

the methods of collecting solar thermal energy depends on the type of the system used to collect the solar energy , the most common types are :

  • active solar heating this method uses low temperature i.e under 100 C ,using glass as a common material , this method used for domestic water heating or swimming pools heating also used for space heating , another type of high temperature active solar heating uses mirrors to amplify the water temperature this commonly used for steam turbines that generate the electricity.
  • passive solar heating this method based on absorption of solar energy directly into the building to reduce the heating load , then using the air to circulate the energy without pumps or fans , the solar collector usually integrated as apart of the building , the lower energy buildings design effectively reduces the heat demand where small passive solar gains make effective contribution in the cold terms.
