SOLAR CONCENTRATOR COMPRISING FLAT MIRRORS ORIENTED NORTH-SOUTH AND A CYLINDRICAL-PARABOLIC SECONDARY MIRROR HAVING A CENTRAL ABSORBER

摘要

The invention relates to a solar power concentrator (CSP) formed by a series of long flat (Fresnel-type) mirrors oriented in a north-south direction, each mirror having a single east-west axis of rotation, tracking the height of the sun. Together the mirrors reflect the light throughout the day towards a single cylindrical-parabolic mirror which concentrates the solar radiation onto a small area close to the focal line of the parabola on which an absorber is located that heats fluids and/or generates electricity.
