2011 was a better year for the German solar thermal industry than 2010, but it still has been far from a good one: Compared to the so far best year, 2008, the collector area installed in 2011 was around 40% less, although figures are still 10 % above the previous year 2010. German’s solar and heating industry associations name different reasons for the dissatisfying market development in the last three years.
