Germany: Cost Optimisation in the Collector Industry

Submitted by Baerbel Epp on September 1, 2011

 ultrasonic welded aluminium absorber” German collector manufacturers have come under high pressure: Copper prices are still on the rise, but the German market is not picking up. Replacing the copper material in the absorber and using a plastic tray instead of an aluminium frame are two of the cost-saving measures the producers have implemented to get sales margins under control. Two German collector manufacturers - STI Solar- Technologie- International and Bosch Thermotechnik - presented collectors with ultrasonic-welded aluminium absorbers and polymer trays on the fairs during the first half of 2011. The photo shows the STI collector, which has an ultrasonic-welded aluminium plate and an aluminium pipe absorber, at the ISH in March.

Slow down after Boom in Germany?

Submitted by Baerbel Epp on December 1, 2008

The crises of the financial markets did not seem to harm the speedy growth of the solar thermal market in Germany. Industry insiders at the conference Forum Solarpraxis in Berlin on the 20th/21st November agreed that the collector area installed in Germany will reach 1.7 to 1.9 million m2 (1.2 to 1.3 GW). This is almost a doubling of the 2007 market volume of 950,000 m2 (665 MW).
