China: solar water heaters on the up
The Chinese market for solar thermal installations has enjoyed a period of enormous growth since the turn of the century. In recent years, this development has been lent further impetus by a series of government measures. China is not only the world's largest solar thermal market, but also the country with the largest solar thermal industry in the world.

Collector bonding: Finding the right adhesive
Two years ago Brötje was forced to recall its FK 24 collectors because there was a risk of panes loosening as a result of inadequate adhesion. Despite this, the use of adhesives in the production of solar collectors is experiencing an upswing – partly because the procedure can be automated.

Solar cooling: a historic chance not to be missed
Solar cooling will not succeed on its own. The sector needs considerably more support than it has received so far. If the attempt to secure this technology a place in the National Renewable Energy Action Plans of the EU countries does not succeed, a historic window of opportunity will close.
SUN & WIND ENERGY 10/2009
On the rise: integrated absorber manufacturing
No other manufacturing step in solar thermal is as consistently automated as absorber manufacture. No matter whether it is the guide roller of the laser head or the sonotrode which is rolling over the absorber. More and more suppliers of welding machines now also offer complete production lines for collector production. SUN & WIND ENERGY would like to introduce them – plus a few newcomers.
SUN & WIND ENERGY 9/2009
Building codes worldwide
Some good ideas take a while to be copied. This is the case with solar building codes, which were invented in Israel 29 years ago. Within the last two to three years, this political instrument has reached all five continents and will develop solar thermal markets in a sustainable way. The world map shows the status quo in 16 countries.

Cairo: Solar heat from garbage
The city planner Thomas Henry Culhane is working together with rubbish collectors in Cairo to make solar heating and biogas plants out of recycled materials. For this initiative the National Geographic Society has awarded him the title “Emerging Explorer 2009”.

Intersolar 2009: From latent heat to solar cooling
Solar stations without collector sensors, latent heat storage tanks, drain-back systems - there was much more on display in the German city of Munich than just innovative collector concepts. The world’s biggest solar energy trade show, Intersolar, presented innovations in storage, stations, complex heating systems with solar heat pumps and solar heating/gas-condensation hybrids.

Large-scale installations across the globe
Large-scale solar thermal systems require a high level of expertise. To help assist planners and installers in project implementation, solar thermal providers around the world are running their own planning and service departments. And more than a few are installing systems on their own as well.

Ambitious targets in the Alpine republic
Austria is years ahead of the rest of Central Europe when it comes to the utilisation of solar thermal energy, which has long been a matter of course there. Furthermore, the expansion goals are more than ambitious: The market is to be expanded 10-fold by 2020.

Heating in hotels: Overcoming a lack of knowledge
Solar thermal systems for hotels are considered a market with a future. Sun & Wind Energy conducted a survey of companies in this sector to see what their experience has been. It turns out that the high upfront costs scare off a lot of hotel operators even though the return on investment is quick.

Solar heating on a grand scale
The grand masters of solar thermal energy come from Denmark. The company ARCON has produced and installed solar thermal systems in the megawatt class for more than 20 years. For several years, it has even done so without any government subsidies.

Schott's new receiver production in Spain
At the end of May, German special glass manufacturer Schott officially opened its production plant for parabolic trough receivers in Andalusia. The plant was under construction from April of 2007 to February of 2008. Schott invested some 25 million euros in the first stage of the plant located within sight of Abengoa's PS 10 and PS 20 solar towers near Sanlúcar la Mayor.

Solar heating by law
More and more cities and towns around the world are passing solar ordinances (obligations), which make solar thermal systems compulsory for new and existing buildings. There are many hurdles to overcome to do this, but once achieved, the communities are sure to gain recognition for their actions.
