Solar Electric Technologies - 2011 Concentrated Photovoltaics CPV Others Solar PowerCommercially Parabolic Trough, Mono-Crystalline, HighAvailable Power Tower Poly-Crystalline, Concentration Thin Film Multi junction Low ConcentrationPilot Plants ,Brayton Cycle Dye Cells, High Parabolic Dish, Cogeneration PV & Concentration Fresnel Water Heaters Multi junction Long-Term Heat Bifacial Cells Low Storage Building Integrated Concentration Solar Boosting (PV (BIPV CPV on WaterResearch & Heat Storage Electricity Storage Solar TowerDevelopment Combined Cycle ((Chimney Super Critical SteamFuture ? CO2 High Temp Cycle Nanotechnology
  • 6. Photovoltaics – Solar Thermal (CSP)• Photovoltaic systems use solar radiation directly to convert light(photons) into direct electrical current (DC)• Thermal systems use concentrating optics, lenses or usually mirrors to concentrate the light (heat) onto a receiver to heat a fluid (e.g. water) to high temperatures and the fluid powers a heat engine (turbine) connected to an electrical generator.
  • 7. Photovoltaics Technologies• Silicon Based Cells• Thin Film
  • 8. Concentrated Solar Power (Thermal)• Concentrating solar power is one of the most ancient ways of using solar energy.• First Solar High Temp. Concentrator was built In Egypt 1912, parabolic solar collectors, were developed by a Philadelphia inventor named Frank Shuman• First Commercial Power Plants Inaugurated In California Mojave Desert 1984 by the Israeli company LUZ
  • 9. CSP TechnologiesParabolic Dish Power Tower Parabolic Trough (Central Receiver) Fresnel Linear Receiver
