Solarserver reports on the world's largest solar heating plant, which has been in operation in China since 2016. It consists of parabolic trough collectors.
On the roof of a XuChen factory hall next to the company headquarters, there are 22,000 m2 collector area, a further 71,000 m2 collector area are implemented as ground-mounted systems. Together they deliver an output of 65 MWth. With concentrating collectors, it would thus be the largest solar heating plant of its kind. An even larger one is the Danish Silkeborg plant (110 MWth)which, however, is equipped with a different collector technology.
By way of comparison, the largest German solar thermal plant supplying a housing estate, neighbourhood or district currently has just 14,800 m².
