  • Solar Power 2011 - Solar PV Breaks Records in 2010

    Solar photovoltaic (PV) companies manufactured a record 24,000 megawatts of PV cells worldwide in 2010, more than doubling their 2009 output. Annual PV production has grown nearly 100-fold since 2000, when just 277 megawatts of cells were made.  Newly installed PV also set a record in 2010, as 16,600 megawatts were installed in more than 100 countries.  This brought the total worldwide ...

  • MENA set to spearhead Solar developments as CSP & PV grind to a halt in the western world

    The solar community in the Western world is undergoing radical change in 2012. Falling PV prices and the ending of the DOE loan guarantees in the US have hit the CSP industry hard, making it difficult to secure the necessary political and financial support to continue development. The PV market is also on the brink of collapse, with damaging effects from government incentive programmes set to ...

  • Mirrors in Space for Low-Cost Terrestrial Solar Electric Power at Night

    ABSTRACT — A constellation of 18 mirror satellites is proposed in a polar sun synchronous dawn to dusk orbit at an altitude of approximately 1000 km above the earth. Each mirror satellite contains a multitude of 2 axis tracking mirror segments that collectively direct a sun beam down at a target solar electric field site delivering a solar intensity to that terrestrial site equivalent to ...

  • Thermal management of non–concentrating photovoltaic panels under extreme ambient conditions

    Solar photovoltaic modules have reduced efficiency levels when the ambient temperature is very high. In this paper, the temperature and the efficiency of a non–concentrating flat plate collector is determined by a one dimensional steady state analysis at different solar radiation levels for the city of Riyadh, Saudi Arabia where the radiation intensity and ambient temperatures are very high. The ...

  • Harnessing the Sun`s Energy for Water and Space Heating

    The pace of solar energy development is accelerating as the installation of rooftop solar water heaters takes off. Unlike solar photovoltaic (PV) panels that convert solar radiation into electricity, these "solar thermal collectors" use the sun's energy to heat water, space, or both. China had an estimated 168 million square meters (1.8 billion square feet) of rooftop solar thermal collectors ...
