The 2017 ranking of the world’s largest flat plate collector producers clearly shows the market dominance of Chinese companies. Even second-ranked
Greenonetec, an Austrian collector manufacturer, is now majority-owned by the Chinese-based
Haier Group. The
corporation acquired 51 % of the manufacturer’s shares on 18 May 2017. The largest European flat plate collector producer was heating technology supplier
Bosch Thermotechnik, although it remained at a certain distance from the top four. Business at Bosch Thermotechnik suffered from declining solar hot water markets in Germany (-16 %) and Brazil (-18 %). Nearly all the companies outside Germany increased production last year.
