A city district in the German town Freiburg will use a solar thermal system for heating and hot water production. During periods with low solar irradiation, the buildings will be supplied with heat from a district heating system.
What happens to a collector when it is exposed to the elements day in and day out? Does it lose a significant amount of its performance over the years or might the frame even crumble at some point? Researchers did not find evidence for any of this. Modern, industrially manufactured collectors are resilient. And not just in the moderate climate of central Europe, but also under extreme conditions such as in tropical India.
On 1 April, Germany introduced yield-dependent funding for solar thermal systems. Even if the funding does not go as far as some had hoped, it is apparently enjoying a high level of acceptance.
During 2015, the UK’s solar thermal market for single households continued its long term decline which started over 5 years ago. This was the opposite of the intended effect of all the government’s incentive schemes over this period but without doubt all these have failed for solar thermal.
