  • Ritter Gruppe - Market leader in Germany

    With its production facility Ritter Solar, the Ritter Gruppe is already market leader in Germany, the largest solar thermal and evacuated tube collector market in Europe! Ritter Solar is the largest supplier of evacuated tube collectors with and without CPC-reflectors within the OEM-Business.

  • Linuo Paradigma - Among the top 5 brands in China

    Linuo Paradigma is one of the most well-known suppliers of solar thermal systems in China. Established in 2001, the Sino-German joint venture has already installed millions of square meters of evacuated tube collectors.



    When thinking of the growing renewable energy industry, solar thermal heating often is an underestimated energy source! According to the International Energy Agency (IEA), in 2007 the total capacity in operation was 147 GW and the produced energy in TWh 89 GW.

    Heating accounts for a significant proportion of the world’s total energy demand. The building sector alone consumes 35.3 %, of which 75 % have already been consumed for domestic water and space heating - and it is increasing continuously! During the coming years and decades, fossil fuels and nuclear power will become increasingly scarce and expensive as a result of the exhaustion of natural resources and the climate change mitigation policies (Source: IEA 2006 and 2007).
