Launch of Solar Thermal Yearbook 2021

Solar thermal energy is indispensable for the energy transition, but just as indispensable is informing the interested public about the state of the art and the wide range of possible solar heat applications. This is the motivation of the editorial team for launching the first English language edition of the Solar Thermal Yearbook Solare Wärme, which has been published annually in German since 2019. The 22-page publication can be downloaded free of charge at
“We are pleased about the interest from abroad, the furthest request came from Canada,” said Detlef Koenemann, publisher of the Solar Thermal Yearbook Solare Wärme. “That is why we are now piloting an English edition.”
The articles in this first publication cover a range of international topics, for example the solar obligation in Barcelona and its effects, a portrait of a Greek company that has been producing solar collectors for almost 50 years, and a solar heating system on the highest mountain hut in the Austrian Alps. Germany’s largest solar house is presented, as is a pioneer in solar thermal systems for district heating networks. There is currently significant growth in Germany in large-scale systems for solar-thermal-supported heating networks. Another article deals with PVT collectors, which combine solar thermal energy and photovoltaics. 
Also included is an article titled Solar thermal energy: And yet it pays off on the biggest misconceptions about solar thermal systems (page 4). It is by far the most read article on the Solar Thermal Yearbook website. “This shows how great the interest is in the technology, but also in independent information about it,” said Jens Peter Meyer, member of the editorial team and author of this article.

The four editors are all dedicated experts on solar heating and cooling and look back at many years of cooperation. All four contributed significantly to the international magazine Sun & Wind Energy, with its dedicated section on solar thermal in each edition. After the publication of Sun & Wind Energy was stopped in 2014, the four journalists joined forces and started the annual publication of the Solar Thermal Yearbook Solare Wärme in 2019 in German.
“With this first edition of Solar Wärme in English we want to test the interest, also from the solar thermal industry, and if possible publish a complete edition in English in 2022,” said Koenemann and he invites people to send feedback to the editorial team ( “Based on this, we will decide whether there will be a more comprehensive international edition in the future.”
All German articles from the magazine Solare Wärme are available for download online. A monthly newsletter can be ordered via the website.
