This 2009 document is the contribution from ESTELA (European Solar Thermal Electricity Association) to the European Commission’s Strategic Energy Technology Plan. The report gives a good overview of the strategic benefits of focusing on solar thermal and connects it with its socio-economic...
Solarge is a European co-operation project promoting the installation of collective solar thermal systems (CSTS) with collector areas of 30m2 and larger. The project looks in particular to multi-family buildings, hotels, public and social buildings. This report, which has been revised in 2007...
This Technical Brochure, published in 2009, presents the final results of the SOLCO project. This project promotes, among other objectives, the widespread use of solar technologies and energy savings due to solar cooling applications in the building sector. The SOLCO project focuses on solar...
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...
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.
Generally speaking, you can differentiate between naturally growing markets and incentive driven markets. In the former, low-cost solar water heaters are already an economic alternative for households to produce hot water instead of using fossil fuels or electricity. Some examples are: China, which is the biggest solar thermal market in the world, Cyprus which has one of the highest solar thermal capacities in operation per capita in the world, and Turkey, which is the third biggest market in the world.
In incentive driven markets like Germany, there are grants for households and companies. In Austria there is a nationwide subsidy scheme for hotels and guesthouses and there are grants at a provincial level for household customers.
A third category is markets driven by legal frameworks such as solar obligations. The most famous example is Israel, where the government – because of the oil crisis – passed an obligation applying to all new residential buildings as well as hotels, old people’s homes and boarding schools 29 years ago. Spain followed two years ago with a national solar obligation. In the meantime 15 countries more adapted renewable building laws or solar obligations. You find further news on this issues in the filter section "key pillars", then "policy" and "obligation".
