"This purchase will allow Conergy to expand its business, especially into the Asian and Southern European markets," Conergy founder and chief executive Hans-Martin Rüter said.

The Cap-Aus team is led by industry specialists Rodger Meads, Mal Hayes and Hans Brekelmans, with a solid background in product development and establishment of distribution networks for solar heat pumps and solar thermal systems.

Cap-Aus managing director Rodger Meads said the success of the product range was based on the cost advantages of its thermosyphon systems over traditional fossil-fuel hot water systems.

"The cost advantage is especially pronounced in sun-rich South-East Asia and Southern Europe," he said.

Christian Langen, managing director of Conergy's Australian subsidiary, said the Cap-Aus acquisition also provides a strong distribution network in these regions in addition to the strength of the Cap-Aus Solitaire and Envirosun brandings.

Conergy's previous acquisitions in the Australian renewable energy market include Quirk's Victory Light Company and Taurus Energy.

Conergy has also recently entered the consumer market for small-scale, consumer oriented wind energy after securing the exclusive rights for the Ampair Wind Generator Pacific 300 within Australia.

The small turbine can generate 12V or 24V power, featuring automatic blade "pitch control" to improve its adaptability to harsh wind conditions.

Conergy also supplies Ampair wind and water generators, the Ampair Pacific and Aquair 100.
