Flagsol Develops New Solar Collector

Flagsol Develops New Solar Collector

Flagsol GmbH, a Solar Millennium technology subsidiary, has developed a new line of parabolic trough collectors. According to the company, a series of innovations means that the investment costs for solar collectors will be reduced by 15 to 20 percent in the future. The new collector has been designed by Flagsol's engineering team in Cologne, Germany.

Offering More Than Ever: Technical Trends in Solar Thermal

There are a wealth of products available in the solar thermal sector, but it is hard to tell which ones match up in the performance stakes. Amin Bennouna explores the evolution of performance and the results of a comparative study of both flat plate and vacuum tube systems.
U.S. Releases Solar Thermal Market Stats

U.S. Releases Solar Thermal Market Stats

The U.S. Energy Information Administration (EIA) released a report this month covering U.S. solar photovoltaic (PV) and solar thermal market activity in 2003. While the U.S. solar thermal market was ho-hum last year, the PV cell and module business was anything but dull. The second-largest manufacturer of photovoltaic (PV) cells and modules, AstroPower, went bankrupt. Other major manufacturers significantly changed their relative outputs of cells and modules, as well as entering and leaving major end-use markets. The result was the first decline in total peak kW production of PV cells and modules since EIA resumed collecting such data in 1986. In this, the second of a two-part series of the U.S. solar market, SolarAccess.com has compiled some key information pertaining to the U.S. solar thermal market. The first installment, covering the U.S. solar PV market can be accessed at this link
Solar Energy Fights for Roof Space

Solar Energy Fights for Roof Space

An increasing problem in today's crowded buildings is finding the best position to fit solar collectors. The two main forms of collectors found on roofs are for water heating (solar thermal) and photovoltaic (solar electricity). If space is short, how can you decide which of these two technologies gets priority?

SolCalor B.V. presents the most efficient solar collector UHV on the world, on the High Tech Campus !!!

At the official launch of our unique solar collector UHV at the High Tech Campus Eindhoven (NL) has been very well responded. Even with a thick layer of snow on the collector, the ultra-high vacuum thermal solar still produce 80 degrees, while the current solar collectors than almost deliver nothing. The European Institute for Nuclear Research in Switzerland has laid the foundations […]
Steamback Shows Promise for Solar Water Overheating

Steamback Shows Promise for Solar Water Overheating

Commercial and residential customers install solutions that heat their water, businesses and homes. But what happens when there is too much of a good thing? Solar water heating systems can and do overheat, creating both inconvenience and cost for the customer. But a European technique called steamback or vapor drainback provides multiple advantages over existing technologies, including fewer service calls, more system uptime, and reduced overall costs.
