In Germany 2017 was the weakest year for solar thermal collector sales in more than a decade, according to the combined statistics by associations BDH and BSW-Solar.
Their data reveals that only 78,000 systems were sold last year. The newly installed collector area added up to 625,000 m², down 16 % from 2016 and as much as 72 % from the boom year of 2008. It was an astonishingly poor showing, considering the strong growth in the construction industry and the high incentive amounts available in Germany.
A press release from 13 February 2018 jointly drafted by associations BSW-Solar, representing the solar industry, and BDH, speaking for the heating sector, explicitly mentioned the around EUR 3,600 that homeowners in Germany could get for a state-of-the-art solar thermal unit including a new boiler. There has been only one requirement, namely that the application must be submitted before the start of the retrofit.
