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...

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.

“Replacing imported fuels with local jobs”, this slogan of the European Solar Thermal Industry Federation (ESTIF) sums up perfectly the advantages of solar thermal technology for a national economy. The six biggest solar thermal markets in Europe – Germany, Austria, Italy, Spain, Greece and France – already exceeded 34,000 full time jobs in 2007 (check related article here). With an annual average growth rate of 20 % that is 6,800 jobs more each year. In the boom year 2008 in Europe this calculation results in 116,000 full-time jobs.
Furthermore solar thermal technology is an export trigger. In mature markets solar thermal industry is reaching high export rates. In 2007, Austria produced four times as many collectors as were newly installed in the country. In Greece, for the first time in 2008, the export will exceed local sales.

The ambitious scenario of the European Solar Thermal Industry Federation (ESTIF) expects Europe will reach 0.7 kWth (1 m2 of collector area) per European in 2020, equivalent to a total capacity in operation in the EU by then of 320 GWth. To reach this target, a suitable support framework will be required and solar will then be widely used for both cooling and supplying process heat, though the majority of this capacity will still supply domestic hot water and space heating. The average yearly growth rate of the EU market necessary to reach this target is 31 % – less than the rate achieved in 2006 and only 7 % above the 2002 to 2006 average. This scenario requires – supposing a linear growth – an installation of 12.2 GWth (17 million m2) in the year 2020, six times more than in 2007, when 2.1 GWth (3 million m2) were newly installed in Europe as a whole.

By far the largest solar thermal market in the world according to newly installed solar thermal capacity per year is China. In 2008, around 21 GWth (30 million m2) were sold in China, which was around 80 % of the world global solar thermal market.
In Europe, Germany – the second biggest market in the world – is dominating. With its newly installed capacity of 1.13 GWth (1,615,000 m2) in 2009, the country reached a market share of 38 % within Europe.
Position three is held by Turkey, a dynamic solar thermal market which is estimated at 785 MWth ( 1,120,000 m2).
Besides these front-runners, India, Brazil, Israel, Austria, Greece, USA, Japan, France, Italy, Spain and Australia are countries which reached a market volume of greater than 70 MWth (100,000 m2) in 2007.

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.
