Demonstration project: Finnish Collector Field Operating in Denmark

Submitted by Baerbel Epp on August 18, 2015
LogumklosterThe first solar district heating collector field in Denmark with direct-flow, aluminium absorbers from Finnish company Savo-Solar came into operation in July 2015. Municipal district heating company Løgumkloster Fjernvarme had ordered 9,400 m² of collector area (6.6 MWth) during the first phase of the project. “If we are satisfied with the performance, we will extend the collector field by 35,000 m² next year,” confirmed Peter G. Andersen, Head of Operations at Løgumkloster Fjernvarme. Savo-Solar used this demonstration project for a successful entry into the Danish district heating market, which was dominated by only one supplier, Arcon-Sunmark, since a merger in February 2015. The Finnish collector manufacturer won the tender by Jelling Varmevaerk in June 2015 and negotiated the final contract for the delivery of 15,000 m² collector area (10.5 WMth) with the municipality in southern Denmark. The utility aims at receiving the permits and confirming the contract by the beginning of November.

Finland: One Solar Roof - Three Partners

Submitted by Baerbel Epp on September 4, 2013

The new Ruukki Classic Solar Thermal Roof from Finland was shown twice this summer: First at the Intersolar Europe in Munich, Germany, at the booth of Finnish company Savo-Solar in June and then at the Finnish Housing Fair in Hyvinkää, Finland, in August. Three rather different companies have been involved in manufacturing, selling and distributing this roof-integrated solar solution. Finnish company Savo-Solar, which specialises in the production of solar collectors based on aluminium absorber sheets, manufactures the collector modules, which are then integrated into steel roof solutions of the Finnish Rautaruukki Corporation (Ruukki), a company known for its steel constructions. The last step in the sales chain is Pohjolan Design-Talo, a Finnish supply company of prefabricated houses, which was also responsible for the demonstration house at the Hyvinkää housing fair.

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.
