What are the long-term future perspectives of the sector worldwide?
The international solar thermal market is growing constantly but with ups and downs. According to the annual study "Solar Heat Worldwide" the newly installed collector area globally grew accordingly:

2005: 10.3 %
2006: 22 %
2007: 8.7 %
The future perspective depends very much on the market development in China. In the last seven years the solar thermal market in the People’s Republic increased at an average rate of 21 % per year.
