Photos: World's largest solar power plant

Germany isn't the sunniest of countries, but it is a hotbed of solar power. And now it's home to what the companies involved are calling the world's largest solar electric power plant. On Friday, Silicon Valley-based SunPower marked the dedication of the Gut Erlasee Solar Park, a 12-megawatt facility located amid cropland near the Bavarian town of Arnstein. SunPower's solar cells are used in about one-third of the "mover" panels--from German solar technology company Solon--that tilt and rotate to stay facing the sun throughout the day.
