PV convert light into electric current using the photoelectric effect. Applications CSP - normally focuses the sun's energy to boil water which is then used to provide power. PV - used to power small and medium-sized applications (from calculators to off-grid homes). Energy storage methods Molten salts. Ø low-cost, Ø have a high specific heat capacity Ø can deliver heat at the right temperature. Solar power plants The 354 MW SEGS CSP installation is the largest solar power plant in the world (California) Other large CSP plants include the Solnova Solar Power Station and the Andasol solar power station, both in Spain. The Charanka Solar Park in India - world's largest PV plant. One 140 acres of unused land on Nellis Air Force Base, Nevada. Click to edit Master text styles Second level Third level
2 2 ml munavalgu lahusele lisansin 2 ml küllastunud lahust. 3 Loksutasin. 4 Jäätsin katseklaasi 5 minutiks seisma. Tekkinud globuliinide sademe eraldasin filtrimise abil. Selleks kasutasin ~5 cm diameetriga filterpaberit ja sobiva suurusega plastiklehtrit. Piisas vaid poole lahuse filtrimisest. 5 Saadud filtraadile lisasin kristalset kuni küllastuskontsentratsiooni saavutamiseni. Selleks lisasin väikeste portsjonitena soola ja loksutasin katseklaasi hoolikalt. Segs tegin nii kaua, kuni soola kristallid enam ei lahustunud. Lahus muutus häguseks. Lahusesse tekkisid valge sademe tükid. Järeldus: Poolküllastanud lahuses (NH4)2SO4 sadenevad globuliinid. Need on jäänud filtris. Albumiinid aga ei sadene poolküllastunud lahuses. Nende sadenemiseks on vajalik küllastunud lahus. (NH4)SO4 lisamisel küllastamiseni jälgime albumiinite sade tekkimist. Kui ma võreldasin globuliinide
world and brought renewed attention to developing solar technologies. Deployment strategies focused on incentive programs such as the Federal Photovoltaic Utilization Program in the US and the Sunshine Program in Japan. Other efforts included the formation of research facilities in the US (SERI, now NREL), Japan (NEDO), and Germany (Fraunhofer Institute for Solar Energy Systems ISE). Commercial concentrating solar power (CSP) plants were first developed in the 1980s. CSP plants such as SEGS project in the United States have a LEC of 1214 ¢/kWh.[139] The 11 MW PS10 power tower in Spain, completed in late 2005, is Europe's first commercial CSP system, and a total capacity of 300 MW is expected to be installed in the same area by 2013. Solar installations in recent years have also largely begun to expand into residential areas, with governments offering incentive programs to make "green" energy a more economically viable option
