a colloquial and descriptive name of the parabolic cylinder (surface of constant parabolic cross-section) used for collecting solar radiation along the focal length Trough systems follow the path of the sun by pivoting on one axis (typically East-West or North-South), using shiny parabolic troughs to heat the collector fluid that passes through a tube at the focus Below is an illustration from the Solar Radiation Data Manual for Flat Plate and Concentrating Collectors
