USA: Solar Heating and Vacuum Tube Collectors are catching up

Submitted by Baerbel Epp on October 27, 2008

The US-American domestic solar heating and cooling market grew by 31 % in 2007, after the rapid climb of 77 % in 2006. These are figures from the annual statistics of the Energy Information Administration (EIA), which publishes the official energy statistics of the U.S. Government. In total 150,000 m2 of collector area was shipped last year (against 111,000 m2 in 2006). The EIA assumes that only 2 % of the total shipment was exported last year; the home market volume was thus 147,000 m2.

Submitted by Baerbel Epp on October 24, 2008

The US-American based renewable system supplier Solar Panels Plus LLC (SPP) has launched an alternative to petroleum-based propylene glycol. The new heat transfer fluid made from corn is completely renewable and biodegradable. “The underlying corn glycol product is made by chemical giant DuPont and we developed our own formula for the production of an efficient heat transfer liquid”, says SPP COO John Williams.

Mature European Market: More than € 2 billion and More than 30,000 Jobs

Submitted by Baerbel Epp on October 23, 2008

The solar thermal market in Europe is by far a mature sector with a substantial total turnover of more than € 2 billion and more than 30,000 jobs. This is shown by the Solar thermal barometer published in October by the French-based organization Observ´ER. These figures result from some simple assumptions.

Submitted by Baerbel Epp on October 17, 2008

Riello Group, the Italian giant in fossil fuel burners, has discovered the solar thermal technology for itself. In September of 2008, the company started producing solar thermal collectors at its production facility in Padua, 35 km north of Venice. “We intend to produce 30,000 m2 of collector area this year”, Silvio Giordano, manager for the new production site, announced.

Promotion of Solar Water Heaters

Submitted by Baerbel Epp on October 17, 2008

This 55-page study "International Experiences with the Promotion of Solar Water Heaters on Household-level", published in October 2006, introduces possible promotion mechanisms for solar water heaters on a household-level. Criteria for their assessment are defined in compliance therewith. The main focus of this paper is on describing and evaluating international experiences with promotion mechanisms in Germany, Greece, France, Tunisia, and Barcelona.
