  • Solar power plants mw or kw?

    Solar power has come as a blessing to the humanity, not only to provide energy to all but to save humanity from the evils of industrial revolution. The biggest evil of industrial revolution in last two centuries is the concentration and centralization of wealth and resources and also huge political powers in the handful of people. So huge factories, mass production, big industrial and financial ...

  • Solar disinfection of natural waters with modified solar concentrators

    Solar water disinfection is a proven method for household purification of drinking water. Compound parabolic collectors (CPCs) have been used to enhance the inactivation rate of microorganisms. In the present study, a modified CPC with a higher concentration ratio of 1.1 was employed to further speed up the process. A large number of tests were conducted with water samples collected from ...

  • Parabolic Trough or Solar Tower? A technology decision

    Securing cost reductions and carving out routes to grid parity remains as ever the most pressing issue for the CSP industry. At the crux of this pursuit is understanding the associated costs of the CSP technologies themselves, whether it be Parabolic Trough, Solar Tower, Linear Fresnel or Dish Sterling. Delving even deeper, the ability to identify and successfully implement cost reduction ...

  • 2013: An important year for CSP in the United States

    Last week the CSP Today Global Tracker revealed that between now and early 2014 the total generation capacity of concentrated solar power in the United States will increase by more than 120%. Currently, 571.16MW of CSP capacity has been commissioned in the United States, but with five large-scale projects scheduled for completion in 2013-14 this capacity is set to increase by 120%, a further ...

  • CSP central to Moroccan renewable targets Recent news that tender for Phase II of the Ouarzazate site in southern Morocco will open at the end of 201

    Recent news that tender for Phase II of the Ouarzazate site in southern Morocco will open at the end of 2013 emphasises the role that concentrated solar power is playing in the country. Press reports indicate that Phase II of the Ouarzazate site will be over 300MW in size.  Adding this to the current 160MW in development of Phase I, this site alone will go some way towards meeting ...

  • Molten salt for parabolic trough applications: system simulation and scale effects

    The trend of solar thermal power plant engineering towards lower investment and energy costs leads to a demand for higher operating temperatures in the plant cycle. The use of molten salts withstanding temperatures up to 550 °C is considered for use in CSP plants, in particular for parabolic trough systems. In thermal storage systems fluids as “Solar Salt” (NaNO3/KNO3) are already ...

  • Characterization of high temperature solar thermal selective absorber coatings at operation temperature

    Abstract In cooperation between the Physikalisch-Technische Bundesanstalt (PTB) and the SCHOTT Solar CSP GmbH (SCHOTT Solar) measurements have been carried out with the goal to assure, that the directional-hemispherical reflectance measurements, done as production control by SCHOTT Solar, lead to applicable results for calculating the emittance of absorber tubes for parabolic trough ...

  • CSP technology advances crucial for cutting costs in South Africa

    With some of the highest levels of Direct Normal Irradiance (DNI) in the world, CSP is positioned to play an immense role in South Africa’s energy landscape. Currently, four CSP technologies are being promoted internationally, parabolic trough, power tower, fresnel and dish stirling, but with the lack of operational data in South Africa the industry is still evaluating the suitability of ...
