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.
