drbubb Posted April 2, 2006 Report Share Posted April 2, 2006 Prices... update ...................................................... : SOLAR- 3 key stocks /Aug.14 : update : ESLR, STP, SIT.L : 3 Solar Shs . Solar cell prices are rising because of the shortage of silicon feedstocks (i believe) STOCKS include : Q-Cells Ag, SunPower Corp., and Suntech Power Holdings Co., Ltd., Opportunity : WHERE is the Sun strong enough... WHERE is the technology employed The seven world leaders in solar energy production include Japan, Switzerland, Germany, Australia, USA, Canada and the United Kingdom. The percentage of the total world solar production from these seven countries and other facts are shown in the table below. Country- - - MW.total Hr.Sun/yr Elec/kWhr w/cap %world Japan........ 301-2001 1200-1600 : 24cents : 2.4 : 45% Switzerland. 15-2000 - - 1700 - - : 12cents : 2.1 : - ? - Germany... 170-2001 1700-1800 : 15cents : 2.0 :. 6% Australia..... 29-2000 2500-3000. : 4 cents : 1.5 : - ? - U.S.A. ..... 139-2000 2000-2500. : 8 cents : 0.5 : 27% Canada........ 7-2000 1500-2500. : 4 cents : .22 : - 0 - U.K. ............ 2-2000 1500-1700 : 12 cents: .03 : 0.75% The map above divides the world into four daily solar radiation zones based on daily hours of sunlight and temperature. The amount of available sunlight varies across the globe. The areas with the most hours of daily sunlight are found near the equator. = = = Solar Technologies Photovoltaics (PV) Photovoltaic solar cells, which directly convert sunlight into electricity, are made of semiconducting materials. The simplest cells power watches and calculators and the like, while more complex systems can light houses and provide power to the electric grid. Passive Solar Heating, Cooling and Daylighting Buildings designed for passive solar and daylighting incorporate design features such as large south-facing windows and building materials that absorb and slowly release the sun's heat. No mechanical means are employed in passive solar heating. Incorporating passive solar designs can reduce heating bills as much as 50 percent. Passive solar designs can also include natural ventilation for cooling. Concentrating Solar Power Concentrating solar power technologies use reflective materials such as mirrors to concentrate the sun's energy. This concentrated heat energy is then converted into electricity. Solar Hot Water and Space Heating and Cooling Solar hot water heaters use the sun to heat either water or a heat-transfer fluid in collectors. A typical system will reduce the need for conventional water heating by about two-thirds. High-temperature solar water heaters can provide energy-efficient hot water and hot water heat for large commercial and industrial facilities. Issues Solar Resources Solar resource information provides data on how much solar energy is available to a collector and how it might vary from month to month, year to year, and location to location. Collecting this information requires a national network of solar radiation monitoring sites. Solar Access The availability or access to unobstructed sunlight for use both in passive solar designs and active systems is protected by zoning laws and ordinances in many communities. Green Power Consumer demand for clean renewable energy and the deregulation of the utilities industry have spurred growth in green power—solar, wind, geothermal steam, biomass, and small-scale hydroelectric sources of power. Small commercial solar power plants have begun serving some energy markets. @: http://www.eere.energy.gov/RE/solar.html = = = = = LINKS: Solar Buzz website..... : http://www.solarbuzz.com/ Solar Plaza news........ : http://www.solarplaza.com/content/news.php Evergreen's Link page : http://academic.evergreen.edu/g/grossmaz/petersj.html Link to comment Share on other sites More sharing options...
