  • Process Heat: the Solar Thermal Challenge of the Future

    So far solar thermal technology is mostly used for domestic hot water, pool heating and room heating. It´s often forgotten that there is a huge demand for heat below 250 °C in industry, which can easily be reached with solar thermal collectors.

    An international team of researchers...

  • Is solar thermal technology still a niche market?

    There are a number of mature markets like Israel, Austria, Barbados, China or Cyprus where solar thermal is used by a wide majority of people for heating the domestic hot water and sometimes for room heating.

    One factor that shows the market penetration of this technology in a certain country is the total capacity installed per capita. In Cyprus there were 0.65 kWth in operation per capita at the end of 2007 followed by Israel (0.5 kWth/head), Austria (0.23 kWth/head) and Barbados (0.2 kWth/head). You find niche markets when looking at market penetrations such as in the United States with only 0.006 kWth per capita or in sunny South Africa with so far not more than 0.0036 kWth per capita. Also, there is still quite a large untouched potential worldwide in using solar thermal technology for cooling and for supplying process heat.

    0.7 kWth nominal solar thermal power equals 1 m2 of collector area.
