The binational cooperation between Switzerland and Poland to support solar thermal technology has reached the halfway mark: According to the Swiss State Secretariat for Economic Affairs (SECO), there were around 30,000 m² of solar water heaters installed between 2012 and 2014. Until the end of the implementation process in December 2016, this number should rise to at least 103,000 m2 for an estimated 20,000 private households and 195 public institutions.
