IEA Study "Solar Heat Worldwide": Global Market Growth of 22 % in 2006

Submitted by Baerbel Epp on June 18, 2008

2006 was an extremely satisfying year for the global solar thermal industry. According to the new study “Solar Heat Worldwide. Markets and contribution to the Energy Supply 2006” on behalf of IEA Solar Heating & Cooling Programme the new installations grew 22 % in 2006. The authors from the Austrian research institute AEE Intec surveyed 48 countries and added up the newly installed collector area to 18.3 GWth (26.1 million m2).

Is there enough sunshine in all regions?

Submitted by Baerbel Epp on May 9, 2008

Solar thermal systems produce hot water whether the system is installed in Sweden, Germany, India, Tunisia or South America. The annual yield depends on the application (domestic hot water, pool heating, space heating), the local climatic conditions and system dimensioning (high or low solar fraction).

What are solar thermal systems made of?

Submitted by Baerbel Epp on May 9, 2008

Flat plat collectors are made of metal, glass, insulating and joining materials. Typically copper, steel or aluminium is used for the absorber configuration. The sides and bottom of the collector are usually metal and insulated with mineral wool to minimize heat loss. The glass top is made of special glass to resist facture and maximise transmission of energy. In the future, a variety of materials and combinations of materials including plastics may be used to improve cost benefits ratios, higher temperature ranges and systems performance.
