Japan was once leading in the solar water heater market. Although being one of the first countries to have solar water heaters installed in 1950, the solar water heater industry has decreased steadily since the 1980’s. In 2007, the country reached a new low with 188,500 m2 of newly installed collector area – not even a tenth of the market volume of 2.8 million m2 it had in the peak year 1980.
Solar showcase in Austria: This single family house in Tyrol generates a 30 % share of the domestic hot water and heating demand from renewable energies. Since 2008 more and more Austrian states have required an ecological heating system, if homeowners want to profit from housing assistance.
Generating electric energy apart from the Sun is not only possible through fotovoltage solar panels, but also from heat produced from solar radiation. The technology able to achieve this is called Thermoelectric Solar.
Solar systems on the balcony: This is the answer to the space problem in the mega-cities in the eastern part of China. Solar obligations force system suppliers to work on systems which can be used on the balcony as shown in this solar exhibition. Already 6 provinces implemented solar building codes.

Since 2006, the solar thermal market in the Netherlands has enjoyed an annual growth rate of 20 – 30%. The currently biggest pieces of the pie go to glycol-drainback solar combination systems (<6 m²). The new incentive programme “Duurzame Warmte” (Sustainable Warmth programme) now offers an even greater opportunity for solar thermal installations. As Arthur de Vries, secretary of the association Holland Solar, said: “We expect this market instrument to be a decisive factor in quickly expanding the market for households.”
Under the new national subsidy scheme of the government of India some more solar cities like Magarpatta in Pune, Maharashtra State, will be realised. The solar thermal market in India has seen a lot of different subsidy models over the years.

Solar roof in the Swedish city of Onsala: The increased subsidies in Sweden focus on larger collector fields – like the 220 m2 plant from 2005.

Namibia has successfully implemented a directive in 2007 which requires SWH on all new public buildings, on existing public buildings without water heaters and existing public buildings with electric geysers. Namibia could reduce its peak electricity demand by almost 20 MW thanks to this directive. Find more details about the solar obligation in the following table.
Second oldest collector manufacturer worldwide: the Japanese company Chiryu Heater which is run by Yasuo Okamoto. He told solarthermalworld.org the history of the company that his father Ei-ichi Okamoto founded in 1944.
