Abstract
Uni-directional radiation vanes for a solar heating system for passing solar radiation and suppressing reradiation in the opposite direction. A plurality of parallel vanes are pivotally mounted. Drive means are connected to the vanes to rotate said vanes in parallel relation to follow the sun so that the sun's rays pass between said vanes. A plurality of grooves on the lower part of said vanes suppress reradiation between said vanes in the opposite direction to the sun's rays.
