Parabolic Troughs

Mirrors and absorption pipes are mounted precisely on steel support structures, which, together, form the collectors in a parabolic trough plant. Flagsol designs and delivers parabolic trough collectors. The metal support structure is anchored in the ground using a steel pylon. The hydraulic drives can adjust the collector chains with a precision of up to a tenth of millimeter allowing them to follow the sun on its daily course from east to west along a single axis. Computers in the plant's control room are used to direct the power plant's collectors.


Parabolic Trough plants have been in commercial operation for more than twenty years in Kramer Junction in the Mojave Desert of California (USA). Newer plants have recently been built in southern Spain and haven been supplying electricity to the Spanish grid since 2008.
