Tremendous Market Growth in Germany

Submitted by Baerbel Epp on March 3, 2009

The German solar thermal market more than doubled in 2008. According to the solar industry association BSW-Solar and the heating industry association BDH; 2.1 million m2 of new collector area (1.5 GWth) were installed on German roofs last year (940,000 m2 = 658 MWth in 2007). This proves to be a great success after the downswing in 2007, when the German solar thermal market experienced a 40 % decrease in collector area installations.

Solar cooling: a new Field for Simulations

Submitted by Baerbel Epp on February 24, 2009

Solar cooling is a promising new field of application for solar thermal technology. A new version of the simulation software Polysun will be published in April. It will not only be able to design solar thermal systems but also solar powered cooling plants that work with compression coolers or fan coils. A version that also contains a simulation model for absorption chillers is scheduled for the summer months. Polysun is offered in Chinese, Czech, English, French, German, Greek, Italian, Portuguese and Spanish.

Italy: Cap for Tax Reductions Removed

Submitted by Baerbel Epp on February 3, 2009

The solar community can breathe a sigh of relief. The sun is shining again over the solar thermal market in Italy. The temporary law of the government from the 29th of November (Decreto Legge 185/08) was approved by the Italian Parliament only after major changes were made on January 27th (see article “Overall Cap for Tax Reductions in Italy”). The law is applicable for deductions granted after 1st of January 2009.

Solar Mega Fairs in Europe breaking Records

Submitted by Baerbel Epp on January 30, 2009

The next three months will be busy ones for the solar thermal industry. Several solar mega fairs will take place in Europe before the end of May.

The fair season starts with the biggest fair of all, the ISH in Frankfurt, Germany, including 2,400 exhibitors on more than 250,000 m2 of exhibition gross space, from the 10th to the 14th of March. Renewable energy technology is one of several areas at the fair, which also includes sanitation, air conditioning and building services.

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).

Solar Heat Used Rarely in Industrial Processes

Submitted by Baerbel Epp on November 14, 2008

If solar heat likes to gain more importance in the future, it should not ignore the industrial sector. Task 33 of the International Energy Agency's (IEA) Solar Heating & Cooling programme performed an analysis of industrial energy needs and looked for the potential of solar heat within the sector. The Task’s scientists found a huge potential for energy from the sun. The industrial sector makes up about 28 % of total primary energy consumption in the European Union. A significant share of the heat used in industrial processes is used at low or medium temperatures.
